Classes

class Accessibility

class Accessibility {}

The Accessibility class provides methods for inspecting the browser's accessibility tree. The accessibility tree is used by assistive technology such as screen readers or switches.
Remarks
Accessibility is a very platform-specific thing. On different platforms, there are different screen readers that might have wildly different output.
Blink - Chrome's rendering engine - has a concept of "accessibility tree", which is then translated into different platform-specific APIs. Accessibility namespace gives users access to the Blink Accessibility Tree.
Most of the accessibility tree gets filtered out when converting from Blink AX Tree to Platform-specific AX-Tree or by assistive technologies themselves. By default, Puppeteer tries to approximate this filtering, exposing only the "interesting" nodes of the tree.
Modifiers
- @public

method snapshot

snapshot: (options?: SnapshotOptions) => Promise<SerializedAXNode | null>;

Captures the current state of the accessibility tree. The returned object represents the root accessible node of the page.
Returns
An AXNode object representing the snapshot.
Remarks
**NOTE** The Chrome accessibility tree contains nodes that go unused on most platforms and by most screen readers. Puppeteer will discard them as well for an easier to process tree, unless interestingOnly is set to false.
Example 1
An example of dumping the entire accessibility tree:
const snapshot = await page.accessibility.snapshot(); console.log(snapshot);
Example 2
An example of logging the focused node's name:
const snapshot = await page.accessibility.snapshot(); const node = findFocusedNode(snapshot); console.log(node && node.name); function findFocusedNode(node) { if (node.focused) return node; for (const child of node.children || []) { const foundNode = findFocusedNode(child); return foundNode; } return null; }

BrowserContext emits various events which are documented in the BrowserContextEvent enum.
If a page opens another page, e.g. using window.open, the popup will belong to the parent page's browser context.
Remarks
In Chrome all non-default contexts are incognito, and default browser context might be incognito if you provide the --incognito argument when launching the browser.

class ElementHandle

abstract class ElementHandle<

ElementHandle represents an in-page DOM element.
Remarks
ElementHandles can be created with the Page.$ method.
import puppeteer from 'puppeteer'; const browser = await puppeteer.launch(); const page = await browser.newPage(); await page.goto('https://example.com'); const hrefElement = await page.$('a'); await hrefElement.click(); // ...
ElementHandle prevents the DOM element from being garbage-collected unless the handle is disposed. ElementHandles are auto-disposed when their associated frame is navigated away or the parent context gets destroyed.
ElementHandle instances can be used as arguments in Page.$eval and Page.evaluate methods.
If you're using TypeScript, ElementHandle takes a generic argument that denotes the type of element the handle is holding within. For example, if you have a handle to a <select> element, you can type it as ElementHandle<HTMLSelectElement> and you get some nicer type checks.

This method scrolls element into view if needed, and then uses Page.screenshot to take a screenshot of the element. If the element is detached from DOM, the method throws an error.

method scrollIntoView

scrollIntoView: (this: ElementHandle<Element>) => Promise<void>;

Scrolls the element into view using either the automation protocol client or by calling element.scrollIntoView.

method select

select: (...values: string[]) => Promise<string[]>;

Triggers a change and input event once all the provided options have been selected. If there's no <select> element matching selector, the method throws an error.
Parameter values
Values of options to select. If the <select> has the multiple attribute, all values are considered, otherwise only the first one is taken into account.
Example 1
handle.select('blue'); // single selection handle.select('red', 'green', 'blue'); // multiple selections

method tap

tap: (this: ElementHandle<Element>) => Promise<void>;

This method scrolls element into view if needed, and then uses Touchscreen.tap to tap in the center of the element. If the element is detached from DOM, the method throws an error.

An error if the handle does not match. **The handle will not be automatically disposed.**

Example 1

const element: ElementHandle<Element> = await page.$(
  '.class-name-of-anchor',
);
// DO NOT DISPOSE `element`, this will be always be the same handle.
const anchor: ElementHandle<HTMLAnchorElement> =
  await element.toElement('a');

method touchEnd

touchEnd: (this: ElementHandle<Element>) => Promise<void>;

method touchMove

touchMove: (this: ElementHandle<Element>, touch?: TouchHandle) => Promise<void>;

This method scrolls the element into view if needed, and then moves the touch to the center of the element.

method waitForSelector

waitForSelector: <Selector extends string>(
    selector: Selector,
    options?: WaitForSelectorOptions
) => Promise<ElementHandle<NodeFor<Selector>> | null>;

Wait for an element matching the given selector to appear in the current element.

class EventEmitter

class EventEmitter<Events extends Record<EventType, unknown>>
    implements CommonEventEmitter<EventsWithWildcard<Events>> {}

The EventEmitter class that many Puppeteer classes extend.
Remarks
This allows you to listen to events that Puppeteer classes fire and act accordingly. Therefore you'll mostly use on and off to bind and unbind to event listeners.
Modifiers
- @public

    type: Key,
    event: EventsWithWildcard<Events>[Key]
) => boolean;

off: <Key extends '*' | keyof Events>(
    type: Key,
    handler?: Handler<EventsWithWildcard<Events>[Key]>
) => this;

Remove an event listener from firing.
Parameter type
the event type you'd like to stop listening to.

this to enable you to chain method calls.

method once

once: <Key extends '*' | keyof Events>(
    type: Key,
    handler: Handler<EventsWithWildcard<Events>[Key]>
) => this;

Like on but the listener will only be fired once and then it will be removed.
Parameter type
the event you'd like to listen to
Parameter handler
the handler function to run when the event occurs
Returns
this to enable you to chain method calls.

method removeAllListeners

removeAllListeners: (type?: keyof EventsWithWildcard<Events>) => this;

Removes all listeners. If given an event argument, it will remove only listeners for that event.
Parameter type
the event to remove listeners for.
Returns
this to enable you to chain method calls.

class ExtensionTransport

class ExtensionTransport implements ConnectionTransport {}

Experimental ExtensionTransport allows establishing a connection via chrome.debugger API if Puppeteer runs in an extension. Since Chrome DevTools Protocol is restricted for extensions, the transport implements missing commands and events.
Modifiers
- @experimental
- @public

property onclose

onclose?: () => void;

property onmessage

onmessage?: (message: string) => void;

method close

close: () => void;

method connectTab

static connectTab: (tabId: number) => Promise<ExtensionTransport>;

method send

send: (message: string) => void;

class FileChooser

class FileChooser {}

File choosers let you react to the page requesting for a file.
Remarks
FileChooser instances are returned via the Page.waitForFileChooser method.
In browsers, only one file chooser can be opened at a time. All file choosers must be accepted or canceled. Not doing so will prevent subsequent file choosers from appearing.
Example 1
const [fileChooser] = await Promise.all([ page.waitForFileChooser(), page.click('#upload-file-button'), // some button that triggers file selection ]); await fileChooser.accept(['/tmp/myfile.pdf']);
Modifiers
- @public

method accept

accept: (paths: string[]) => Promise<void>;

Accept the file chooser request with the given file paths.
Remarks
This will not validate whether the file paths exists. Also, if a path is relative, then it is resolved against the current working directory. For locals script connecting to remote chrome environments, paths must be absolute.

method cancel

cancel: () => Promise<void>;

Closes the file chooser without selecting any files.

method isMultiple

isMultiple: () => boolean;

Whether file chooser allow for multiple file selection.

class Frame

abstract class Frame extends EventEmitter<FrameEvents> {}

Represents a DOM frame.

To understand frames, you can think of frames as <iframe> elements. Just like iframes, frames can be nested, and when JavaScript is executed in a frame, the JavaScript does not affect frames inside the ambient frame the JavaScript executes in.

Remarks

Frame lifecycles are controlled by three events that are all dispatched on the parent page:

- PageEvent.FrameAttached - PageEvent.FrameNavigated - PageEvent.FrameDetached

Example 1

At any point in time, pages expose their current frame tree via the Page.mainFrame and Frame.childFrames methods.

Example 2

An example of dumping frame tree:

import puppeteer from 'puppeteer';

const browser = await puppeteer.launch();
const page = await browser.newPage();
await page.goto('https://www.google.com/chrome/browser/canary.html');
dumpFrameTree(page.mainFrame(), '');
await browser.close();

function dumpFrameTree(frame, indent) {
  console.log(indent + frame.url());
  for (const child of frame.childFrames()) {
    dumpFrameTree(child, indent + '  ');
  }
}

Example 3

An example of getting text from an iframe element:

const frames = page.frames();
let frame = null;
for (const currentFrame of frames) {
  const frameElement = await currentFrame.frameElement();
  const name = await frameElement.evaluate(el => el.getAttribute('name'));
  if (name === 'myframe') {
    frame = currentFrame;
    break;
  }
}
if (frame) {
  const text = await frame.$eval(
    '.selector',
    element => element.textContent,
  );
  console.log(text);
} else {
  console.error('Frame with name "myframe" not found.');
}

Modifiers

@public

    selector: Selector
) => Promise<ElementHandle<NodeFor<Selector>> | null>;

Queries the frame for an element matching the given selector.
Parameter selector

Returns
A element handle to the first element matching the given selector. Otherwise, null.

method $$

$$: <Selector extends string>(
    selector: Selector,
    options?: QueryOptions
) => Promise<Array<ElementHandle<NodeFor<Selector>>>>;

An array of element handles that point to elements matching the given selector.

method $$eval

$$eval: <
    Selector extends string,
    Params extends unknown[],
    Func extends EvaluateFuncWith<
        ParseSelector<ComplexSelector>[],
        Params
    > = EvaluateFuncWith<ParseSelector<ComplexSelector>[], Params>
>(
    selector: Selector,
    pageFunction: string | Func,
    ...args: Params
) => Promise<Awaited<ReturnType<Func>>>;

Runs the given function on an array of elements matching the given selector in the frame.
If the given function returns a promise, then this method will wait till the promise resolves.
Parameter selector
selector to query the page for. CSS selectors can be passed as-is and a Puppeteer-specific selector syntax allows querying by text, a11y role and name, and xpath and combining these queries across shadow roots. Alternatively, you can specify the selector type using a prefix.

Example 1
const divsCounts = await frame.$$eval('div', divs => divs.length);

method $eval

$eval: <
    Selector extends string,
    Params extends unknown[],
    Func extends EvaluateFuncWith<
        ParseSelector<ComplexSelector>,
        Params

options to configure the polling method, timeout and signal.

Parameter args

arguments to pass to the pageFunction.

Returns

the promise which resolve when the pageFunction returns a truthy value.

Example 1

The waitForFunction can be used to observe viewport size change:

import puppeteer from 'puppeteer';

const browser = await puppeteer.launch();
const page = await browser.newPage();
const watchDog = page
  .mainFrame()
  .waitForFunction('window.innerWidth < 100');
page.setViewport({width: 50, height: 50});
await watchDog;
await browser.close();

To pass arguments from Node.js to the predicate of page.waitForFunction function:

const selector = '.foo';
await frame.waitForFunction(
  selector => !!document.querySelector(selector),
  {}, // empty options object
  selector,
);

method waitForNavigation

abstract waitForNavigation: (
    options?: WaitForOptions
) => Promise<HTTPResponse | null>;

Waits for the frame to navigate. It is useful for when you run code which will indirectly cause the frame to navigate.
Usage of the History API to change the URL is considered a navigation.
Parameter options
Options to configure waiting behavior.
Returns
A promise which resolves to the main resource response.
Example 1
const [response] = await Promise.all([ // The navigation promise resolves after navigation has finished frame.waitForNavigation(), // Clicking the link will indirectly cause a navigation frame.click('a.my-link'), ]);

method waitForSelector

waitForSelector: <Selector extends string>(
    selector: Selector,
    options?: WaitForSelectorOptions
) => Promise<ElementHandle<NodeFor<Selector>> | null>;

Waits for an element matching the given selector to appear in the frame.

This method works across navigations.

Parameter selector

The selector to query and wait for.

Parameter options

Options for customizing waiting behavior.

Returns

An element matching the given selector.

Throws

Throws if an element matching the given selector doesn't appear.

Example 1

import puppeteer from 'puppeteer';

const browser = await puppeteer.launch();
const page = await browser.newPage();
let currentURL;
page
  .mainFrame()
  .waitForSelector('img')
  .then(() => console.log('First URL with image: ' + currentURL));

for (currentURL of [
  'https://example.com',
  'https://google.com',
  'https://bbc.com',
]) {
  await page.goto(currentURL);
}
await browser.close();

class HTTPRequest

abstract class HTTPRequest {}

Represents an HTTP request sent by a page.
Remarks
Whenever the page sends a request, such as for a network resource, the following events are emitted by Puppeteer's page:
- request: emitted when the request is issued by the page.
- requestfinished - emitted when the response body is downloaded and the request is complete.
If request fails at some point, then instead of requestfinished event the requestfailed event is emitted.
All of these events provide an instance of HTTPRequest representing the request that occurred:
page.on('request', request => ...)
NOTE: HTTP Error responses, such as 404 or 503, are still successful responses from HTTP standpoint, so request will complete with requestfinished event.
If request gets a 'redirect' response, the request is successfully finished with the requestfinished event, and a new request is issued to a redirected url.

method failure

abstract failure: () => { errorText: string } | null;

Access information about the request's failure.
Returns
null unless the request failed. If the request fails this can return an object with errorText containing a human-readable error message, e.g. net::ERR_FAILED. It is not guaranteed that there will be failure text if the request fails.

class Keyboard

abstract class Keyboard {}

Keyboard provides an api for managing a virtual keyboard. The high level api is Keyboard.type, which takes raw characters and generates proper keydown, keypress/input, and keyup events on your page.
Remarks
For finer control, you can use Keyboard.down, Keyboard.up, and Keyboard.sendCharacter to manually fire events as if they were generated from a real keyboard.
On macOS, keyboard shortcuts like ⌘ A -> Select All do not work. See #1313.
Example 1
An example of holding down Shift in order to select and delete some text:
await page.keyboard.type('Hello World!'); await page.keyboard.press('ArrowLeft'); await page.keyboard.down('Shift'); for (let i = 0; i < ' World'.length; i++) await page.keyboard.press('ArrowLeft'); await page.keyboard.up('Shift'); await page.keyboard.press('Backspace'); // Result text will end up saying 'Hello!'

Remarks
If key is a single character and no modifier keys besides Shift are being held down, a keypress/input event will also generated. The text option can be specified to force an input event to be generated. If key is a modifier key, Shift, Meta, Control, or Alt, subsequent key presses will be sent with that modifier active. To release the modifier key, use Keyboard.up.
After the key is pressed once, subsequent calls to Keyboard.down will have repeat set to true. To release the key, use Keyboard.up.
Modifier keys DO influence Keyboard.down. Holding down Shift will type the text in upper case.

class Mouse

abstract class Mouse {}

The Mouse class operates in main-frame CSS pixels relative to the top-left corner of the viewport.

Remarks

Every page object has its own Mouse, accessible with Page.mouse.

Example 1

// Using ‘page.mouse’ to trace a 100x100 square.
await page.mouse.move(0, 0);
await page.mouse.down();
await page.mouse.move(0, 100);
await page.mouse.move(100, 100);
await page.mouse.move(100, 0);
await page.mouse.move(0, 0);
await page.mouse.up();

**Note**: The mouse events trigger synthetic MouseEvents. This means that it does not fully replicate the functionality of what a normal user would be able to do with their mouse.

For example, dragging and selecting text is not possible using page.mouse. Instead, you can use the `DocumentOrShadowRoot.getSelection()` functionality implemented in the platform.

Example 2

For example, if you want to select all content between nodes:

await page.evaluate(
  (from, to) => {
    const selection = from.getRootNode().getSelection();
    const range = document.createRange();
    range.setStartBefore(from);
    range.setEndAfter(to);
    selection.removeAllRanges();
    selection.addRange(range);
  },
  fromJSHandle,
  toJSHandle,
);

If you then would want to copy-paste your selection, you can use the clipboard api:

// The clipboard api does not allow you to copy, unless the tab is focused.
await page.bringToFront();
await page.evaluate(() => {
  // Copy the selected content to the clipboard
  document.execCommand('copy');
  // Obtain the content of the clipboard as a string
  return navigator.clipboard.readText();
});

**Note**: If you want access to the clipboard API, you have to give it permission to do so:

await browser
  .defaultBrowserContext()
  .overridePermissions('<your origin>', [
    'clipboard-read',
    'clipboard-write',
  ]);

class Page

abstract class Page extends EventEmitter<PageEvents> {}

Page provides methods to interact with a single tab or extension background page in the browser.
:::note
One Browser instance might have multiple Page instances.
:::
Example 1
This example creates a page, navigates it to a URL, and then saves a screenshot:
import puppeteer from 'puppeteer'; const browser = await puppeteer.launch(); const page = await browser.newPage(); await page.goto('https://example.com'); await page.screenshot({path: 'screenshot.png'}); await browser.close();
The Page class extends from Puppeteer's EventEmitter class and will emit various events which are documented in the PageEvent enum.
Example 2
This example logs a message for a single page load event:
page.once('load', () => console.log('Page loaded!'));
To unsubscribe from events use the EventEmitter.off method:
function logRequest(interceptedRequest) { console.log('A request was made:', interceptedRequest.url()); } page.on('request', logRequest); // Sometime later... page.off('request', logRequest);

selector to query the page for. CSS selectors can be passed as-is and a Puppeteer-specific selector syntax allows querying by text, a11y role and name, and xpath and combining these queries across shadow roots. Alternatively, you can specify the selector type using a prefix.
Remarks
Shortcut for Page.mainFrame().$(selector).

method $$

$$: <Selector extends string>(
    selector: Selector,
    options?: QueryOptions
) => Promise<Array<ElementHandle<NodeFor<Selector>>>>;

Finds elements on the page that match the selector. If no elements match the selector, the return value resolves to [].
Parameter selector
selector to query the page for. CSS selectors can be passed as-is and a Puppeteer-specific selector syntax allows querying by text, a11y role and name, and xpath and combining these queries across shadow roots. Alternatively, you can specify the selector type using a prefix.
Remarks
Shortcut for Page.mainFrame().$$(selector).

method $$eval

$$eval: <
    Selector extends string,
    Params extends unknown[],
    Func extends EvaluateFuncWith<
        ParseSelector<ComplexSelector>[],
        Params
    > = EvaluateFuncWith<ParseSelector<ComplexSelector>[], Params>
>(
    selector: Selector,
    pageFunction: Func | string,
    ...args: Params
) => Promise<Awaited<ReturnType<Func>>>;

This method returns all elements matching the selector and passes the resulting array as the first argument to the pageFunction.
Parameter selector
selector to query the page for. CSS selectors can be passed as-is and a Puppeteer-specific selector syntax allows querying by text, a11y role and name, and xpath and combining these queries across shadow roots. Alternatively, you can specify the selector type using a prefix.
Parameter pageFunction
the function to be evaluated in the page context. Will be passed an array of matching elements as its first argument.
Parameter args
any additional arguments to pass through to pageFunction.
Returns
The result of calling pageFunction. If it returns an element it is wrapped in an ElementHandle, else the raw value itself is returned.
Remarks
If pageFunction returns a promise $$eval will wait for the promise to resolve and then return its value.
Example 1
// get the amount of divs on the page const divCount = await page.$$eval('div', divs => divs.length); // get the text content of all the `.options` elements: const options = await page.$$eval('div > span.options', options => { return options.map(option => option.textContent); });
If you are using TypeScript, you may have to provide an explicit type to the first argument of the pageFunction. By default it is typed as Element[], but you may need to provide a more specific sub-type:
Example 2
await page.$$eval('input', elements => { return elements.map(e => e.value); });
The compiler should be able to infer the return type from the pageFunction you provide. If it is unable to, you can use the generic type to tell the compiler what return type you expect from $$eval:
Example 3
const allInputValues = await page.$$eval('input', elements => elements.map(e => e.textContent), );

method $eval

$eval: <
    Selector extends string,
    Params extends unknown[],
    Func extends EvaluateFuncWith<
        ParseSelector<ComplexSelector>,
        Params
    > = EvaluateFuncWith<ParseSelector<ComplexSelector>, Params>
>(
    selector: Selector,
    pageFunction: Func | string,
    ...args: Params
) => Promise<Awaited<ReturnType<Func>>>;

This method finds the first element within the page that matches the selector and passes the result as the first argument to the pageFunction.
Parameter selector
selector to query the page for. CSS selectors can be passed as-is and a Puppeteer-specific selector syntax allows querying by text, a11y role and name, and xpath and combining these queries across shadow roots. Alternatively, you can specify the selector type using a prefix.
Parameter pageFunction
the function to be evaluated in the page context. Will be passed the result of the element matching the selector as its first argument.
Parameter args
any additional arguments to pass through to pageFunction.
Returns
The result of calling pageFunction. If it returns an element it is wrapped in an ElementHandle, else the raw value itself is returned.
Remarks
If no element is found matching selector, the method will throw an error.
If pageFunction returns a promise $eval will wait for the promise to resolve and then return its value.
Example 1
const searchValue = await page.$eval('#search', el => el.value); const preloadHref = await page.$eval('link[rel=preload]', el => el.href); const html = await page.$eval('.main-container', el => el.outerHTML);
If you are using TypeScript, you may have to provide an explicit type to the first argument of the pageFunction. By default it is typed as Element, but you may need to provide a more specific sub-type:
Example 2
// if you don't provide HTMLInputElement here, TS will error // as `value` is not on `Element` const searchValue = await page.$eval( '#search', (el: HTMLInputElement) => el.value, );
The compiler should be able to infer the return type from the pageFunction you provide. If it is unable to, you can use the generic type to tell the compiler what return type you expect from $eval:
Example 3
// The compiler can infer the return type in this case, but if it can't // or if you want to be more explicit, provide it as the generic type. const searchValue = await page.$eval<string>( '#search', (el: HTMLInputElement) => el.value, );

method addScriptTag

addScriptTag: (
    options: FrameAddScriptTagOptions
) => Promise<ElementHandle<HTMLScriptElement>>;

Adds a <script> tag into the page with the desired URL or content.
Parameter options
Options for the script.
Returns
An element handle to the injected <script> element.
Remarks
Shortcut for page.mainFrame().addScriptTag(options).

method addStyleTag

addStyleTag: {
    (options: Omit<FrameAddStyleTagOptions, 'url'>): Promise<
        ElementHandle<HTMLStyleElement>
    >;
    (options: FrameAddStyleTagOptions): Promise<ElementHandle<HTMLLinkElement>>;
};

Adds a <link rel="stylesheet"> tag into the page with the desired URL or a <style type="text/css"> tag with the content.
Shortcut for page.mainFrame().addStyleTag(options).
Returns
An element handle to the injected <link> or <style> element.

method authenticate

abstract authenticate: (credentials: Credentials | null) => Promise<void>;

Provide credentials for HTTP authentication.
:::note
Request interception will be turned on behind the scenes to implement authentication. This might affect performance.
:::
Remarks
To disable authentication, pass null.

method bringToFront

abstract bringToFront: () => Promise<void>;

Brings page to front (activates tab).

method browser

abstract browser: () => Browser;

Get the browser the page belongs to.

abstract browserContext: () => BrowserContext;

Get the browser context that the page belongs to.

method captureHeapSnapshot

abstract captureHeapSnapshot: (options: HeapSnapshotOptions) => Promise<void>;

Captures a snapshot of the JavaScript heap and writes it to a file.

method click

click: (selector: string, options?: Readonly<ClickOptions>) => Promise<void>;

This method fetches an element with selector, scrolls it into view if needed, and then uses Page.mouse to click in the center of the element. If there's no element matching selector, the method throws an error.
Parameter selector
selector to query the page for. CSS selectors can be passed as-is and a Puppeteer-specific selector syntax allows querying by text, a11y role and name, and xpath and combining these queries across shadow roots. Alternatively, you can specify the selector type using a prefix. If there are multiple elements satisfying the selector, the first will be clicked
Parameter options
Object
Returns
Promise which resolves when the element matching selector is successfully clicked. The Promise will be rejected if there is no element matching selector.
Remarks
Bear in mind that if click() triggers a navigation event and there's a separate page.waitForNavigation() promise to be resolved, you may end up with a race condition that yields unexpected results. The correct pattern for click and wait for navigation is the following:
const [response] = await Promise.all([ page.waitForNavigation(waitOptions), page.click(selector, clickOptions), ]);
Shortcut for page.mainFrame().click(selector[, options]).

method close

abstract close: (options?: { runBeforeUnload?: boolean }) => Promise<void>;

method content

content: () => Promise<string>;

The full HTML contents of the page, including the DOCTYPE.

method cookies

abstract cookies: (...urls: string[]) => Promise<Cookie[]>;

If no URLs are specified, this method returns cookies for the current page URL. If URLs are specified, only cookies for those URLs are returned.
Deprecated
Page-level cookie API is deprecated. Use Browser.cookies or BrowserContext.cookies instead.

method createCDPSession

abstract createCDPSession: () => Promise<CDPSession>;

Creates a Chrome Devtools Protocol session attached to the page.

method createPDFStream

abstract createPDFStream: (
    options?: PDFOptions
) => Promise<ReadableStream<Uint8Array>>;

Generates a PDF of the page with the print CSS media type.
Parameter options
options for generating the PDF.
Remarks
To generate a PDF with the screen media type, call `page.emulateMediaType('screen')` before calling page.pdf().
By default, page.pdf() generates a pdf with modified colors for printing. Use the `-webkit-print-color-adjust` property to force rendering of exact colors.

method deleteCookie

abstract deleteCookie: (...cookies: DeleteCookiesRequest[]) => Promise<void>;

Deprecated
Page-level cookie API is deprecated. Use Browser.deleteCookie, BrowserContext.deleteCookie, Browser.deleteMatchingCookies or BrowserContext.deleteMatchingCookies instead.

method emulate

emulate: (device: Device) => Promise<void>;

Emulates a given device's metrics and user agent.
To aid emulation, Puppeteer provides a list of known devices that can be via KnownDevices.
Remarks
This method is a shortcut for calling two methods: Page.setUserAgent and Page.setViewport.
This method will resize the page. A lot of websites don't expect phones to change size, so you should emulate before navigating to the page.
Example 1
import {KnownDevices} from 'puppeteer'; const iPhone = KnownDevices['iPhone 15 Pro']; const browser = await puppeteer.launch(); const page = await browser.newPage(); await page.emulate(iPhone); await page.goto('https://www.google.com'); // other actions... await browser.close();

method emulateCPUThrottling

    isScreenUnlocked: boolean;
}) => Promise<void>;

Emulates the idle state. If no arguments set, clears idle state emulation.

Parameter overrides

Mock idle state. If not set, clears idle overrides

Example 1

// set idle emulation
await page.emulateIdleState({isUserActive: true, isScreenUnlocked: false});

// do some checks here
...

// clear idle emulation
await page.emulateIdleState();

method emulateMediaFeatures

abstract emulateMediaFeatures: (features?: MediaFeature[]) => Promise<void>;

Parameter features

<?Array<Object>> Given an array of media feature objects, emulates CSS media features on the page. Each media feature object must have the following properties:

Example 1

await page.emulateMediaFeatures([
  {name: 'prefers-color-scheme', value: 'dark'},
]);
await page.evaluate(
  () => matchMedia('(prefers-color-scheme: dark)').matches,
);
// → true
await page.evaluate(
  () => matchMedia('(prefers-color-scheme: light)').matches,
);
// → false

await page.emulateMediaFeatures([
  {name: 'prefers-reduced-motion', value: 'reduce'},
]);
await page.evaluate(
  () => matchMedia('(prefers-reduced-motion: reduce)').matches,
);
// → true
await page.evaluate(
  () => matchMedia('(prefers-reduced-motion: no-preference)').matches,

  () => matchMedia('(prefers-color-scheme: light)').matches,
);
// → false
await page.evaluate(
  () => matchMedia('(prefers-reduced-motion: reduce)').matches,
);
// → true
await page.evaluate(
  () => matchMedia('(prefers-reduced-motion: no-preference)').matches,
);
// → false

await page.emulateMediaFeatures([{name: 'color-gamut', value: 'p3'}]);
await page.evaluate(() => matchMedia('(color-gamut: srgb)').matches);
// → true
await page.evaluate(() => matchMedia('(color-gamut: p3)').matches);
// → true
await page.evaluate(() => matchMedia('(color-gamut: rec2020)').matches);
// → false

method emulateMediaType

abstract emulateMediaType: (type?: string) => Promise<void>;

Parameter type

Changes the CSS media type of the page. The only allowed values are screen, print and null. Passing null disables CSS media emulation.

Example 1

await page.evaluate(() => matchMedia('screen').matches);
// → true
await page.evaluate(() => matchMedia('print').matches);
// → false

await page.emulateMediaType('print');
await page.evaluate(() => matchMedia('screen').matches);
// → false
await page.evaluate(() => matchMedia('print').matches);
// → true

await page.emulateMediaType(null);
await page.evaluate(() => matchMedia('screen').matches);
// → true
await page.evaluate(() => matchMedia('print').matches);
// → false

method emulateNetworkConditions

abstract emulateNetworkConditions: (
    networkConditions: NetworkConditions | null
) => Promise<void>;

This does not affect WebSockets and WebRTC PeerConnections (see https://crbug.com/563644). To set the page offline, you can use Page.setOfflineMode.

A list of predefined network conditions can be used by importing PredefinedNetworkConditions.

Parameter networkConditions

Passing null disables network condition emulation.

Example 1

import {PredefinedNetworkConditions} from 'puppeteer';
const slow3G = PredefinedNetworkConditions['Slow 3G'];

const browser = await puppeteer.launch();
const page = await browser.newPage();
await page.emulateNetworkConditions(slow3G);
await page.goto('https://www.google.com');
// other actions...
await browser.close();

method emulateTimezone

abstract emulateTimezone: (timezoneId?: string) => Promise<void>;

Parameter timezoneId
Changes the timezone of the page. See ICU’s metaZones.txt for a list of supported timezone IDs. Passing null disables timezone emulation.

method emulateVisionDeficiency

abstract emulateVisionDeficiency: (
    type?: Protocol.Emulation.SetEmulatedVisionDeficiencyRequest
) => Promise<void>;

Simulates the given vision deficiency on the page.

Parameter type

the type of deficiency to simulate, or 'none' to reset.

Example 1

import puppeteer from 'puppeteer';

const browser = await puppeteer.launch();
const page = await browser.newPage();
await page.goto('https://v8.dev/blog/10-years');

await page.emulateVisionDeficiency('achromatopsia');
await page.screenshot({path: 'achromatopsia.png'});

await page.emulateVisionDeficiency('deuteranopia');
await page.screenshot({path: 'deuteranopia.png'});

await page.emulateVisionDeficiency('blurredVision');
await page.screenshot({path: 'blurred-vision.png'});

await page.emulateVisionDeficiency('reducedContrast');
await page.screenshot({path: 'reduced-contrast.png'});

await browser.close();

method evaluate

evaluate: <
    Params extends unknown[],
    Func extends EvaluateFunc<Params> = EvaluateFunc<Params>
>(
    pageFunction: Func | string,
    ...args: Params
) => Promise<Awaited<ReturnType<Func>>>;

Evaluates a function in the page's context and returns the result.
If the function passed to page.evaluate returns a Promise, the function will wait for the promise to resolve and return its value.
Parameter pageFunction
a function that is run within the page
Parameter args
arguments to be passed to the pageFunction
Returns
the return value of pageFunction.
Example 1
const result = await frame.evaluate(() => { return Promise.resolve(8 * 7); }); console.log(result); // prints "56"
You can pass a string instead of a function (although functions are recommended as they are easier to debug and use with TypeScript):
Example 2
const aHandle = await page.evaluate('1 + 2');
To get the best TypeScript experience, you should pass in as the generic the type of pageFunction:
const aHandle = await page.evaluate(() => 2);
Example 3
ElementHandle instances (including JSHandles) can be passed as arguments to the pageFunction:
const bodyHandle = await page.$('body'); const html = await page.evaluate(body => body.innerHTML, bodyHandle); await bodyHandle.dispose();

method evaluateHandle

evaluateHandle: <
    Params extends unknown[],
    Func extends EvaluateFunc<Params> = EvaluateFunc<Params>
>(
    pageFunction: Func | string,
    ...args: Params
) => Promise<HandleFor<Awaited<ReturnType<Func>>>>;

Parameter pageFunction
a function that is run within the page
Parameter args
arguments to be passed to the pageFunction
Remarks
The only difference between page.evaluate and page.evaluateHandle is that evaluateHandle will return the value wrapped in an in-page object.
If the function passed to page.evaluateHandle returns a Promise, the function will wait for the promise to resolve and return its value.
You can pass a string instead of a function (although functions are recommended as they are easier to debug and use with TypeScript):
Example 1
const aHandle = await page.evaluateHandle('document');
Example 2
JSHandle instances can be passed as arguments to the pageFunction:
const aHandle = await page.evaluateHandle(() => document.body); const resultHandle = await page.evaluateHandle( body => body.innerHTML, aHandle, ); console.log(await resultHandle.jsonValue()); await resultHandle.dispose();
Most of the time this function returns a JSHandle, but if pageFunction returns a reference to an element, you instead get an ElementHandle back:
Example 3
const button = await page.evaluateHandle(() => document.querySelector('button'), ); // can call `click` because `button` is an `ElementHandle` await button.click();
The TypeScript definitions assume that evaluateHandle returns a JSHandle, but if you know it's going to return an ElementHandle, pass it as the generic argument:
const button = await page.evaluateHandle<ElementHandle>(...);

method evaluateOnNewDocument

abstract evaluateOnNewDocument: <
    Params extends unknown[],
    Func extends (...args: Params) => unknown = (...args: Params) => unknown
>(
    pageFunction: Func | string,
    ...args: Params
) => Promise<NewDocumentScriptEvaluation>;

Adds a function which would be invoked in one of the following scenarios:
- whenever the page is navigated
- whenever the child frame is attached or navigated. In this case, the function is invoked in the context of the newly attached frame.
The function is invoked after the document was created but before any of its scripts were run. This is useful to amend the JavaScript environment, e.g. to seed Math.random.
Parameter pageFunction
Function to be evaluated in browser context
Parameter args
Arguments to pass to pageFunction
Example 1
An example of overriding the navigator.languages property before the page loads:
// preload.js // overwrite the `languages` property to use a custom getter Object.defineProperty(navigator, 'languages', { get: function () { return ['en-US', 'en', 'bn']; }, }); // In your puppeteer script, assuming the preload.js file is // in same folder of our script. const preloadFile = fs.readFileSync('./preload.js', 'utf8'); await page.evaluateOnNewDocument(preloadFile);

method exposeFunction

abstract exposeFunction: (
    name: string,
    pptrFunction: Function | { default: Function }
) => Promise<void>;

The method adds a function called name on the page's window object. When called, the function executes puppeteerFunction in node.js and returns a Promise which resolves to the return value of puppeteerFunction.

If the puppeteerFunction returns a Promise, it will be awaited.

:::note

Functions installed via page.exposeFunction survive navigations.

:::

Parameter name

Name of the function on the window object

Parameter pptrFunction

Callback function which will be called in Puppeteer's context.

Example 1

An example of adding an md5 function into the page:

import puppeteer from 'puppeteer';
import crypto from 'crypto';

const browser = await puppeteer.launch();
const page = await browser.newPage();
page.on('console', msg => console.log(msg.text()));
await page.exposeFunction('md5', text =>
  crypto.createHash('md5').update(text).digest('hex'),
);
await page.evaluate(async () => {
  // use window.md5 to compute hashes
  const myString = 'PUPPETEER';
  const myHash = await window.md5(myString);
  console.log(`md5 of ${myString} is ${myHash}`);
});
await browser.close();

Example 2

An example of adding a window.readfile function into the page:

import puppeteer from 'puppeteer';
import fs from 'node:fs';

const browser = await puppeteer.launch();
const page = await browser.newPage();
page.on('console', msg => console.log(msg.text()));
await page.exposeFunction('readfile', async filePath => {
  return new Promise((resolve, reject) => {
    fs.readFile(filePath, 'utf8', (err, text) => {
      if (err) reject(err);
      else resolve(text);
    });
  });
});
await page.evaluate(async () => {
  // use window.readfile to read contents of a file
  const content = await window.readfile('/etc/hosts');
  console.log(content);
});
await browser.close();

method focus

Parameter selector
selector to query the page for. CSS selectors can be passed as-is and a Puppeteer-specific selector syntax allows querying by text, a11y role and name, and xpath and combining these queries across shadow roots. Alternatively, you can specify the selector type using a prefix. If there are multiple elements satisfying the selector, the first will be hovered.

While a screenshot is being taken in a BrowserContext, the following methods will automatically wait for the screenshot to finish to prevent interference with the screenshot process: BrowserContext.newPage, Browser.newPage, Page.close.
Calling Page.bringToFront will not wait for existing screenshot operations.

method select

select: (selector: string, ...values: string[]) => Promise<string[]>;

Triggers a change and input event once all the provided options have been selected. If there's no <select> element matching selector, the method throws an error.
Parameter selector
selector to query the page for. CSS selectors can be passed as-is and a Puppeteer-specific selector syntax allows querying by text, a11y role and name, and xpath and combining these queries across shadow roots. Alternatively, you can specify the selector type using a prefix.
Parameter values
Values of options to select. If the <select> has the multiple attribute, all values are considered, otherwise only the first one is taken into account.
Returns
Remarks
Shortcut for page.mainFrame().select()
Example 1
page.select('select#colors', 'blue'); // single selection page.select('select#colors', 'red', 'green', 'blue'); // multiple selections

method setBypassCSP

abstract setBypassCSP: (enabled: boolean) => Promise<void>;

Toggles bypassing page's Content-Security-Policy.
Parameter enabled
sets bypassing of page's Content-Security-Policy.
Remarks
NOTE: CSP bypassing happens at the moment of CSP initialization rather than evaluation. Usually, this means that page.setBypassCSP should be called before navigating to the domain.

We no longer support intercepting drag payloads. Use the new drag APIs found on ElementHandle to drag (or just use the Page.mouse).

method setExtraHTTPHeaders

abstract setExtraHTTPHeaders: (headers: Record<string, string>) => Promise<void>;

The extra HTTP headers will be sent with every request the page initiates.
:::tip
All HTTP header names are lowercased. (HTTP headers are case-insensitive, so this shouldn’t impact your server code.)
:::
:::note
page.setExtraHTTPHeaders does not guarantee the order of headers in the outgoing requests.
:::
Parameter headers
An object containing additional HTTP headers to be sent with every request. All header values must be strings.

method setGeolocation

abstract setGeolocation: (options: GeolocationOptions) => Promise<void>;

Sets the page's geolocation.

It does not change the download/upload/latency parameters set by Page.emulateNetworkConditions
Parameter enabled
When true, enables offline mode for the page.

method setRequestInterception

abstract setRequestInterception: (value: boolean) => Promise<void>;

Activating request interception enables HTTPRequest.abort, HTTPRequest.continue and HTTPRequest.respond methods. This provides the capability to modify network requests that are made by a page.
Once request interception is enabled, every request will stall unless it's continued, responded or aborted; or completed using the browser cache.
See the Request interception guide for more details.
Parameter value
Whether to enable request interception.
Example 1
An example of a naïve request interceptor that aborts all image requests:
import puppeteer from 'puppeteer'; const browser = await puppeteer.launch(); const page = await browser.newPage(); await page.setRequestInterception(true); page.on('request', interceptedRequest => { if ( interceptedRequest.url().endsWith('.png') || interceptedRequest.url().endsWith('.jpg') ) interceptedRequest.abort(); else interceptedRequest.continue(); }); await page.goto('https://example.com'); await browser.close();

method setUserAgent

abstract setUserAgent: {
    (
        userAgent: string,
        userAgentMetadata?: Protocol.Emulation.UserAgentMetadata
    ): Promise<void>;
    (options: {
        userAgent?: string;
        userAgentMetadata?: Protocol.Emulation.UserAgentMetadata;
        platform?: string;
    }): Promise<void>;
};

Parameter userAgent
Specific user agent to use in this page
Parameter userAgentData
Specific user agent client hint data to use in this page
Returns
Promise which resolves when the user agent is set.
Deprecated
Use Page.setUserAgent instead.
Parameter options
Object containing user agent and optional user agent metadata
Returns
Promise which resolves when the user agent is set.

method setViewport

abstract setViewport: (viewport: Viewport | null) => Promise<void>;

page.setViewport will resize the page. A lot of websites don't expect phones to change size, so you should set the viewport before navigating to the page.
In the case of multiple pages in a single browser, each page can have its own viewport size. Setting the viewport to null resets the viewport to its default value.
Parameter viewport
Remarks
NOTE: in certain cases, setting viewport will reload the page in order to set the isMobile or hasTouch properties.
Example 1
const page = await browser.newPage(); await page.setViewport({ width: 640, height: 480, deviceScaleFactor: 1, }); await page.goto('https://example.com');

method tap

tap: (selector: string) => Promise<void>;

This method fetches an element with selector, scrolls it into view if needed, and then uses Page.touchscreen to tap in the center of the element. If there's no element matching selector, the method throws an error.
Parameter selector
selector to query the page for. CSS selectors can be passed as-is and a Puppeteer-specific selector syntax allows querying by text, a11y role and name, and xpath and combining these queries across shadow roots. Alternatively, you can specify the selector type using a prefix. If there are multiple elements satisfying the selector, the first will be tapped.
Remarks
Shortcut for page.mainFrame().tap(selector).

method target

abstract target: () => Target;

A target this page was created from.
Deprecated
Use Page.createCDPSession directly.

method title

title: () => Promise<string>;

The page's title
Remarks
Shortcut for page.mainFrame().title().

method type

type: (
    selector: string,
    text: string,
    options?: Readonly<KeyboardTypeOptions>
) => Promise<void>;

Sends a keydown, keypress/input, and keyup event for each character in the text.
To press a special key, like Control or ArrowDown, use Keyboard.press.
Parameter selector
selector to query the page for. CSS selectors can be passed as-is and a Puppeteer-specific selector syntax allows querying by text, a11y role and name, and xpath and combining these queries across shadow roots. Alternatively, you can specify the selector type using a prefix.
Parameter text
A text to type into a focused element.
Parameter options
have property delay which is the Time to wait between key presses in milliseconds. Defaults to 0.
Returns
Example 1
await page.type('#mytextarea', 'Hello'); // Types instantly await page.type('#mytextarea', 'World', {delay: 100}); // Types slower, like a user

method url

url: () => string;

The page's URL.
Remarks
Shortcut for page.mainFrame().url().

method viewport

abstract viewport: () => Viewport | null;

Returns the current page viewport settings without checking the actual page viewport.
This is either the viewport set with the previous Page.setViewport call or the default viewport set via ConnectOptions.defaultViewport.

method waitForDevicePrompt

abstract waitForDevicePrompt: (
    options?: WaitTimeoutOptions
) => Promise<DeviceRequestPrompt>;

This method is typically coupled with an action that triggers a device request from an api such as WebBluetooth.
:::caution
This must be called before the device request is made. It will not return a currently active device prompt.
:::
Example 1
const [devicePrompt] = Promise.all([ page.waitForDevicePrompt(), page.click('#connect-bluetooth'), ]); await devicePrompt.select( await devicePrompt.waitForDevice(({name}) => name.includes('My Device')), );

method waitForFileChooser

abstract waitForFileChooser: (
    options?: WaitTimeoutOptions
) => Promise<FileChooser>;

This method is typically coupled with an action that triggers file choosing.
:::caution
This must be called before the file chooser is launched. It will not return a currently active file chooser.
:::
:::caution
Interception of file dialogs triggered via DOM APIs such as window.showOpenFilePicker is currently not supported.
:::
Remarks
In the "headful" browser, this method results in the native file picker dialog not showing up for the user.
Example 1
The following example clicks a button that issues a file chooser and then responds with /tmp/myfile.pdf as if a user has selected this file.
const [fileChooser] = await Promise.all([ page.waitForFileChooser(), page.click('#upload-file-button'), // some button that triggers file selection ]); await fileChooser.accept(['/tmp/myfile.pdf']);

method waitForFrame

waitForFrame: (
    urlOrPredicate: string | ((frame: Frame) => Awaitable<boolean>),
    options?: WaitTimeoutOptions
) => Promise<Frame>;

Waits for a frame matching the given conditions to appear.

Example 1

const frame = await page.waitForFrame(async frame => {
  const frameElement = await frame.frameElement();
  if (!frameElement) {
    return false;
  }
  const name = await frameElement.evaluate(el => el.getAttribute('name'));
  return name === 'test';
});

method waitForFunction

waitForFunction: <
    Params extends unknown[],
    Func extends EvaluateFunc<Params> = EvaluateFunc<Params>
>(
    pageFunction: Func | string,
    options?: FrameWaitForFunctionOptions,
    ...args: Params
) => Promise<HandleFor<Awaited<ReturnType<Func>>>>;

Waits for the provided function, pageFunction, to return a truthy value when evaluated in the page's context.

Parameter pageFunction

Function to be evaluated in browser context until it returns a truthy value.

Parameter options

Options for configuring waiting behavior.

Example 1

Page.waitForFunction can be used to observe a viewport size change:

import puppeteer from 'puppeteer';

const browser = await puppeteer.launch();
const page = await browser.newPage();
const watchDog = page.waitForFunction('window.innerWidth < 100');
await page.setViewport({width: 50, height: 50});
await watchDog;
await browser.close();

Example 2

Arguments can be passed from Node.js to pageFunction:

const selector = '.foo';
await page.waitForFunction(
  selector => !!document.querySelector(selector),
  {},
  selector,
);

Example 3

The provided pageFunction can be asynchronous:

const username = 'github-username';
await page.waitForFunction(
  async username => {
    const githubResponse = await fetch(
      `https://api.github.com/users/${username}`,
    );
    const githubUser = await githubResponse.json();
    // show the avatar
    const img = document.createElement('img');
    img.src = githubUser.avatar_url;
    // wait 3 seconds
    await new Promise((resolve, reject) => setTimeout(resolve, 3000));
    img.remove();
  },
  {},
  username,
);

method waitForNavigation

waitForNavigation: (options?: WaitForOptions) => Promise<HTTPResponse | null>;

Waits for the page to navigate to a new URL or to reload. It is useful when you run code that will indirectly cause the page to navigate.
Parameter options
Navigation parameters which might have the following properties:
Returns
A Promise which resolves to the main resource response.
- In case of multiple redirects, the navigation will resolve with the response of the last redirect. - In case of navigation to a different anchor or navigation due to History API usage, the navigation will resolve with null.
Remarks
Usage of the History API to change the URL is considered a navigation.
Example 1
const [response] = await Promise.all([ page.waitForNavigation(), // The promise resolves after navigation has finished page.click('a.my-link'), // Clicking the link will indirectly cause a navigation ]);

method waitForNetworkIdle

waitForNetworkIdle: (options?: WaitForNetworkIdleOptions) => Promise<void>;

Waits for the network to be idle.
Parameter options
Options to configure waiting behavior.
Returns
A promise which resolves once the network is idle.

- signal: A signal object that allows you to cancel a waitForResponse call.
Example 1
const firstResponse = await page.waitForResponse( 'https://example.com/resource', ); const finalResponse = await page.waitForResponse( response => response.url() === 'https://example.com' && response.status() === 200, ); const finalResponse = await page.waitForResponse(async response => { return (await response.text()).includes('<html>'); }); return finalResponse.ok();

method waitForSelector

waitForSelector: <Selector extends string>(
    selector: Selector,
    options?: WaitForSelectorOptions
) => Promise<ElementHandle<NodeFor<Selector>> | null>;

Wait for the selector to appear in page. If at the moment of calling the method the selector already exists, the method will return immediately. If the selector doesn't appear after the timeout milliseconds of waiting, the function will throw.
Parameter selector

Evaluates a given function in the worker.
Parameter func
Function to be evaluated.
Parameter args
Arguments to pass into func.
Returns
The result of func.
Remarks
If the given function returns a promise, evaluate will wait for the promise to resolve.
As a rule of thumb, if the return value of the given function is more complicated than a JSON object (e.g. most classes), then evaluate will _likely_ return some truncated value (or {}). This is because we are not returning the actual return value, but a deserialized version as a result of transferring the return value through a protocol to Puppeteer.
In general, you should use evaluateHandle if evaluate cannot serialize the return value properly or you need a mutable handle to the return object.

method evaluateHandle

evaluateHandle: <
    Params extends unknown[],
    Func extends EvaluateFunc<Params> = EvaluateFunc<Params>
>(
    func: Func | string,

Evaluates a given function in the worker.
Parameter func
Function to be evaluated.
Parameter args

Returns
A handle to the return value of func.
Remarks
If the given function returns a promise, evaluate will wait for the promise to resolve.
In general, you should use evaluateHandle if evaluate cannot serialize the return value properly or you need a mutable handle to the return object.

interface BluetoothEmulation

interface BluetoothEmulation {}

Exposes the bluetooth emulation abilities.
Remarks
Web Bluetooth specification requires the emulated adapters should be isolated per top-level navigable. However, at the moment Chromium's bluetooth emulation implementation is tight to the browser context, not the page. This means the bluetooth emulation exposed from different pages of the same browser context would interfere their states.
Example 1
await page.bluetooth.emulateAdapter('powered-on'); await page.bluetooth.simulatePreconnectedPeripheral({ address: '09:09:09:09:09:09', name: 'SOME_NAME', manufacturerData: [ { key: 17, data: 'AP8BAX8=', }, ], knownServiceUuids: ['12345678-1234-5678-9abc-def123456789'], }); await page.bluetooth.disableEmulation();

class Accessibility

class Accessibility {}

The Accessibility class provides methods for inspecting the browser's accessibility tree. The accessibility tree is used by assistive technology such as screen readers or switches.
Remarks
Accessibility is a very platform-specific thing. On different platforms, there are different screen readers that might have wildly different output.
Blink - Chrome's rendering engine - has a concept of "accessibility tree", which is then translated into different platform-specific APIs. Accessibility namespace gives users access to the Blink Accessibility Tree.
Most of the accessibility tree gets filtered out when converting from Blink AX Tree to Platform-specific AX-Tree or by assistive technologies themselves. By default, Puppeteer tries to approximate this filtering, exposing only the "interesting" nodes of the tree.
Modifiers
- @public

method snapshot

snapshot: (options?: SnapshotOptions) => Promise<SerializedAXNode | null>;

Captures the current state of the accessibility tree. The returned object represents the root accessible node of the page.
Returns
An AXNode object representing the snapshot.
Remarks
**NOTE** The Chrome accessibility tree contains nodes that go unused on most platforms and by most screen readers. Puppeteer will discard them as well for an easier to process tree, unless interestingOnly is set to false.
Example 1
An example of dumping the entire accessibility tree:
const snapshot = await page.accessibility.snapshot(); console.log(snapshot);
Example 2
An example of logging the focused node's name:
const snapshot = await page.accessibility.snapshot(); const node = findFocusedNode(snapshot); console.log(node && node.name); function findFocusedNode(node) { if (node.focused) return node; for (const child of node.children || []) { const foundNode = findFocusedNode(child); return foundNode; } return null; }

class Browser

abstract class Browser extends EventEmitter<BrowserEvents> {}

Browser represents a browser instance that is either:

- connected to via Puppeteer.connect or - launched by PuppeteerNode.launch.

Browser emits various events which are documented in the BrowserEvent enum.

Example 1

Using a Browser to create a Page:

import puppeteer from 'puppeteer';

const browser = await puppeteer.launch();
const page = await browser.newPage();
await page.goto('https://example.com');
await browser.close();

Example 2

Disconnecting from and reconnecting to a Browser:

import puppeteer from 'puppeteer';

const browser = await puppeteer.launch();
// Store the endpoint to be able to reconnect to the browser.
const browserWSEndpoint = browser.wsEndpoint();
// Disconnect puppeteer from the browser.
await browser.disconnect();

// Use the endpoint to reestablish a connection
const browser2 = await puppeteer.connect({browserWSEndpoint});
// Close the browser.
await browser2.close();

class BrowserContext

abstract class BrowserContext extends EventEmitter<BrowserContextEvents> {}

BrowserContext represents individual user contexts within a browser.
When a browser is launched, it has at least one default browser context. Others can be created using Browser.createBrowserContext. Each context has isolated storage (cookies/localStorage/etc.)
BrowserContext emits various events which are documented in the BrowserContextEvent enum.
If a page opens another page, e.g. using window.open, the popup will belong to the parent page's browser context.
Remarks
In Chrome all non-default contexts are incognito, and default browser context might be incognito if you provide the --incognito argument when launching the browser.

class ElementHandle

abstract class ElementHandle<

import puppeteer from 'puppeteer'; const browser = await puppeteer.launch(); const page = await browser.newPage(); await page.goto('https://example.com'); const hrefElement = await page.$('a'); await hrefElement.click(); // ...
ElementHandle prevents the DOM element from being garbage-collected unless the handle is disposed. ElementHandles are auto-disposed when their associated frame is navigated away or the parent context gets destroyed.
ElementHandle instances can be used as arguments in Page.$eval and Page.evaluate methods.
If you're using TypeScript, ElementHandle takes a generic argument that denotes the type of element the handle is holding within. For example, if you have a handle to a <select> element, you can type it as ElementHandle<HTMLSelectElement> and you get some nicer type checks.

Throws

An error if the handle does not match. **The handle will not be automatically disposed.**

Example 1

const element: ElementHandle<Element> = await page.$(
  '.class-name-of-anchor',
);
// DO NOT DISPOSE `element`, this will be always be the same handle.
const anchor: ElementHandle<HTMLAnchorElement> =
  await element.toElement('a');

method touchEnd

touchEnd: (this: ElementHandle<Element>) => Promise<void>;

method touchMove

touchMove: (this: ElementHandle<Element>, touch?: TouchHandle) => Promise<void>;

This method scrolls the element into view if needed, and then moves the touch to the center of the element.
Parameter touch
An optional TouchHandle. If provided, this touch will be moved. If not provided, the first active touch will be moved.

method touchStart

touchStart: (this: ElementHandle<Element>) => Promise<TouchHandle>;

This will not validate whether the file paths exists. Also, if a path is relative, then it is resolved against the current working directory. For locals script connecting to remote chrome environments, paths must be absolute.

method waitForSelector

waitForSelector: <Selector extends string>(
    selector: Selector,
    options?: WaitForSelectorOptions
) => Promise<ElementHandle<NodeFor<Selector>> | null>;

Wait for an element matching the given selector to appear in the current element.

Returns
this to enable you to chain method calls.

class ExtensionTransport

class ExtensionTransport implements ConnectionTransport {}

Experimental ExtensionTransport allows establishing a connection via chrome.debugger API if Puppeteer runs in an extension. Since Chrome DevTools Protocol is restricted for extensions, the transport implements missing commands and events.
Modifiers
- @experimental
- @public

property onclose

onclose?: () => void;

property onmessage

onmessage?: (message: string) => void;

method close

close: () => void;

class FileChooser

class FileChooser {}

File choosers let you react to the page requesting for a file.
Remarks
FileChooser instances are returned via the Page.waitForFileChooser method.
In browsers, only one file chooser can be opened at a time. All file choosers must be accepted or canceled. Not doing so will prevent subsequent file choosers from appearing.
Example 1
const [fileChooser] = await Promise.all([ page.waitForFileChooser(), page.click('#upload-file-button'), // some button that triggers file selection ]); await fileChooser.accept(['/tmp/myfile.pdf']);
Modifiers
- @public

method accept

accept: (paths: string[]) => Promise<void>;

Accept the file chooser request with the given file paths.
Remarks
This will not validate whether the file paths exists. Also, if a path is relative, then it is resolved against the current working directory. For locals script connecting to remote chrome environments, paths must be absolute.

method cancel

cancel: () => Promise<void>;

Closes the file chooser without selecting any files.

method isMultiple

isMultiple: () => boolean;

Whether file chooser allow for multiple file selection.

class Frame

abstract class Frame extends EventEmitter<FrameEvents> {}

Represents a DOM frame.

Remarks

Frame lifecycles are controlled by three events that are all dispatched on the parent page:

- PageEvent.FrameAttached - PageEvent.FrameNavigated - PageEvent.FrameDetached

Example 1

At any point in time, pages expose their current frame tree via the Page.mainFrame and Frame.childFrames methods.

Example 2

An example of dumping frame tree:

import puppeteer from 'puppeteer';

const browser = await puppeteer.launch();
const page = await browser.newPage();
await page.goto('https://www.google.com/chrome/browser/canary.html');
dumpFrameTree(page.mainFrame(), '');
await browser.close();

function dumpFrameTree(frame, indent) {
  console.log(indent + frame.url());
  for (const child of frame.childFrames()) {
    dumpFrameTree(child, indent + '  ');
  }
}

Example 3

An example of getting text from an iframe element:

const frames = page.frames();
let frame = null;
for (const currentFrame of frames) {
  const frameElement = await currentFrame.frameElement();
  const name = await frameElement.evaluate(el => el.getAttribute('name'));
  if (name === 'myframe') {
    frame = currentFrame;
    break;
  }
}
if (frame) {
  const text = await frame.$eval(
    '.selector',
    element => element.textContent,
  );
  console.log(text);
} else {
  console.error('Frame with name "myframe" not found.');
}

Modifiers

method $$

$$: <Selector extends string>(
    selector: Selector,
    options?: QueryOptions
) => Promise<Array<ElementHandle<NodeFor<Selector>>>>;

Usage of the History API to change the URL is considered a navigation.
Parameter options
Options to configure waiting behavior.
Returns
A promise which resolves to the main resource response.
Example 1
const [response] = await Promise.all([ // The navigation promise resolves after navigation has finished frame.waitForNavigation(), // Clicking the link will indirectly cause a navigation frame.click('a.my-link'), ]);

method waitForSelector

waitForSelector: <Selector extends string>(
    selector: Selector,
    options?: WaitForSelectorOptions
) => Promise<ElementHandle<NodeFor<Selector>> | null>;

Waits for an element matching the given selector to appear in the frame.

This method works across navigations.

Parameter selector

The selector to query and wait for.

Parameter options

Options for customizing waiting behavior.

Returns

An element matching the given selector.

Throws

Throws if an element matching the given selector doesn't appear.

Example 1

import puppeteer from 'puppeteer';

const browser = await puppeteer.launch();
const page = await browser.newPage();
let currentURL;
page
  .mainFrame()
  .waitForSelector('img')
  .then(() => console.log('First URL with image: ' + currentURL));

for (currentURL of [
  'https://example.com',
  'https://google.com',
  'https://bbc.com',
]) {
  await page.goto(currentURL);
}
await browser.close();

class HTTPRequest

abstract class HTTPRequest {}

Represents an HTTP request sent by a page.
Remarks
Whenever the page sends a request, such as for a network resource, the following events are emitted by Puppeteer's page:
- request: emitted when the request is issued by the page.
- requestfinished - emitted when the response body is downloaded and the request is complete.
If request fails at some point, then instead of requestfinished event the requestfailed event is emitted.
All of these events provide an instance of HTTPRequest representing the request that occurred:
page.on('request', request => ...)
NOTE: HTTP Error responses, such as 404 or 503, are still successful responses from HTTP standpoint, so request will complete with requestfinished event.
If request gets a 'redirect' response, the request is successfully finished with the requestfinished event, and a new request is issued to a redirected url.

method failure

abstract failure: () => { errorText: string } | null;

Access information about the request's failure.
Returns
null unless the request failed. If the request fails this can return an object with errorText containing a human-readable error message, e.g. net::ERR_FAILED. It is not guaranteed that there will be failure text if the request fails.

class Keyboard

abstract class Keyboard {}

Keyboard provides an api for managing a virtual keyboard. The high level api is Keyboard.type, which takes raw characters and generates proper keydown, keypress/input, and keyup events on your page.
Remarks
For finer control, you can use Keyboard.down, Keyboard.up, and Keyboard.sendCharacter to manually fire events as if they were generated from a real keyboard.
On macOS, keyboard shortcuts like ⌘ A -> Select All do not work. See #1313.
Example 1
An example of holding down Shift in order to select and delete some text:
await page.keyboard.type('Hello World!'); await page.keyboard.press('ArrowLeft'); await page.keyboard.down('Shift'); for (let i = 0; i < ' World'.length; i++) await page.keyboard.press('ArrowLeft'); await page.keyboard.up('Shift'); await page.keyboard.press('Backspace'); // Result text will end up saying 'Hello!'

Remarks
If key is a single character and no modifier keys besides Shift are being held down, a keypress/input event will also generated. The text option can be specified to force an input event to be generated. If key is a modifier key, Shift, Meta, Control, or Alt, subsequent key presses will be sent with that modifier active. To release the modifier key, use Keyboard.up.
After the key is pressed once, subsequent calls to Keyboard.down will have repeat set to true. To release the key, use Keyboard.up.
Modifier keys DO influence Keyboard.down. Holding down Shift will type the text in upper case.

class Mouse

abstract class Mouse {}

The Mouse class operates in main-frame CSS pixels relative to the top-left corner of the viewport.

Remarks

Every page object has its own Mouse, accessible with Page.mouse.

Example 1

// Using ‘page.mouse’ to trace a 100x100 square.
await page.mouse.move(0, 0);
await page.mouse.down();
await page.mouse.move(0, 100);
await page.mouse.move(100, 100);
await page.mouse.move(100, 0);
await page.mouse.move(0, 0);
await page.mouse.up();

**Note**: The mouse events trigger synthetic MouseEvents. This means that it does not fully replicate the functionality of what a normal user would be able to do with their mouse.

For example, dragging and selecting text is not possible using page.mouse. Instead, you can use the `DocumentOrShadowRoot.getSelection()` functionality implemented in the platform.

Example 2

For example, if you want to select all content between nodes:

await page.evaluate(
  (from, to) => {
    const selection = from.getRootNode().getSelection();
    const range = document.createRange();
    range.setStartBefore(from);
    range.setEndAfter(to);
    selection.removeAllRanges();
    selection.addRange(range);
  },
  fromJSHandle,
  toJSHandle,
);

If you then would want to copy-paste your selection, you can use the clipboard api:

// The clipboard api does not allow you to copy, unless the tab is focused.
await page.bringToFront();
await page.evaluate(() => {
  // Copy the selected content to the clipboard
  document.execCommand('copy');
  // Obtain the content of the clipboard as a string
  return navigator.clipboard.readText();
});

**Note**: If you want access to the clipboard API, you have to give it permission to do so:

await browser
  .defaultBrowserContext()
  .overridePermissions('<your origin>', [
    'clipboard-read',
    'clipboard-write',
  ]);

class Page

abstract class Page extends EventEmitter<PageEvents> {}

Page provides methods to interact with a single tab or extension background page in the browser.
:::note
One Browser instance might have multiple Page instances.
:::
Example 1
This example creates a page, navigates it to a URL, and then saves a screenshot:
import puppeteer from 'puppeteer'; const browser = await puppeteer.launch(); const page = await browser.newPage(); await page.goto('https://example.com'); await page.screenshot({path: 'screenshot.png'}); await browser.close();
The Page class extends from Puppeteer's EventEmitter class and will emit various events which are documented in the PageEvent enum.
Example 2
This example logs a message for a single page load event:
page.once('load', () => console.log('Page loaded!'));
To unsubscribe from events use the EventEmitter.off method:
function logRequest(interceptedRequest) { console.log('A request was made:', interceptedRequest.url()); } page.on('request', logRequest); // Sometime later... page.off('request', logRequest);

        Params
    > = EvaluateFuncWith<ParseSelector<ComplexSelector>[], Params>
>(
    selector: Selector,
    pageFunction: Func | string,
    ...args: Params
) => Promise<Awaited<ReturnType<Func>>>;

This method returns all elements matching the selector and passes the resulting array as the first argument to the pageFunction.
Parameter selector
selector to query the page for. CSS selectors can be passed as-is and a Puppeteer-specific selector syntax allows querying by text, a11y role and name, and xpath and combining these queries across shadow roots. Alternatively, you can specify the selector type using a prefix.
Parameter pageFunction
the function to be evaluated in the page context. Will be passed an array of matching elements as its first argument.
Parameter args
any additional arguments to pass through to pageFunction.
Returns
The result of calling pageFunction. If it returns an element it is wrapped in an ElementHandle, else the raw value itself is returned.
Remarks
If pageFunction returns a promise $$eval will wait for the promise to resolve and then return its value.
Example 1
// get the amount of divs on the page const divCount = await page.$$eval('div', divs => divs.length); // get the text content of all the `.options` elements: const options = await page.$$eval('div > span.options', options => { return options.map(option => option.textContent); });
If you are using TypeScript, you may have to provide an explicit type to the first argument of the pageFunction. By default it is typed as Element[], but you may need to provide a more specific sub-type:
Example 2
await page.$$eval('input', elements => { return elements.map(e => e.value); });
The compiler should be able to infer the return type from the pageFunction you provide. If it is unable to, you can use the generic type to tell the compiler what return type you expect from $$eval:
Example 3
const allInputValues = await page.$$eval('input', elements => elements.map(e => e.textContent), );

method $eval

$eval: <
    Selector extends string,
    Params extends unknown[],
    Func extends EvaluateFuncWith<
        ParseSelector<ComplexSelector>,
        Params
    > = EvaluateFuncWith<ParseSelector<ComplexSelector>, Params>
>(
    selector: Selector,
    pageFunction: Func | string,
    ...args: Params
) => Promise<Awaited<ReturnType<Func>>>;

This method finds the first element within the page that matches the selector and passes the result as the first argument to the pageFunction.
Parameter selector
selector to query the page for. CSS selectors can be passed as-is and a Puppeteer-specific selector syntax allows querying by text, a11y role and name, and xpath and combining these queries across shadow roots. Alternatively, you can specify the selector type using a prefix.
Parameter pageFunction
the function to be evaluated in the page context. Will be passed the result of the element matching the selector as its first argument.
Parameter args
any additional arguments to pass through to pageFunction.
Returns
The result of calling pageFunction. If it returns an element it is wrapped in an ElementHandle, else the raw value itself is returned.
Remarks
If no element is found matching selector, the method will throw an error.
If pageFunction returns a promise $eval will wait for the promise to resolve and then return its value.
Example 1
const searchValue = await page.$eval('#search', el => el.value); const preloadHref = await page.$eval('link[rel=preload]', el => el.href); const html = await page.$eval('.main-container', el => el.outerHTML);
If you are using TypeScript, you may have to provide an explicit type to the first argument of the pageFunction. By default it is typed as Element, but you may need to provide a more specific sub-type:
Example 2
// if you don't provide HTMLInputElement here, TS will error // as `value` is not on `Element` const searchValue = await page.$eval( '#search', (el: HTMLInputElement) => el.value, );
The compiler should be able to infer the return type from the pageFunction you provide. If it is unable to, you can use the generic type to tell the compiler what return type you expect from $eval:
Example 3
// The compiler can infer the return type in this case, but if it can't // or if you want to be more explicit, provide it as the generic type. const searchValue = await page.$eval<string>( '#search', (el: HTMLInputElement) => el.value, );

method addScriptTag

addScriptTag: (
    options: FrameAddScriptTagOptions
) => Promise<ElementHandle<HTMLScriptElement>>;

Adds a <script> tag into the page with the desired URL or content.
Parameter options
Options for the script.
Returns
An element handle to the injected <script> element.
Remarks
Shortcut for page.mainFrame().addScriptTag(options).

method addStyleTag

addStyleTag: {
    (options: Omit<FrameAddStyleTagOptions, 'url'>): Promise<
        ElementHandle<HTMLStyleElement>
    >;
    (options: FrameAddStyleTagOptions): Promise<ElementHandle<HTMLLinkElement>>;
};

Adds a <link rel="stylesheet"> tag into the page with the desired URL or a <style type="text/css"> tag with the content.
Shortcut for page.mainFrame().addStyleTag(options).
Returns
An element handle to the injected <link> or <style> element.

method authenticate

abstract authenticate: (credentials: Credentials | null) => Promise<void>;

Provide credentials for HTTP authentication.
:::note
Request interception will be turned on behind the scenes to implement authentication. This might affect performance.
:::
Remarks
To disable authentication, pass null.

method bringToFront

abstract bringToFront: () => Promise<void>;

Brings page to front (activates tab).

method browser

abstract browser: () => Browser;

Get the browser the page belongs to.

method browserContext

abstract browserContext: () => BrowserContext;

Get the browser context that the page belongs to.

abstract captureHeapSnapshot: (options: HeapSnapshotOptions) => Promise<void>;

Captures a snapshot of the JavaScript heap and writes it to a file.

method click

click: (selector: string, options?: Readonly<ClickOptions>) => Promise<void>;

This method fetches an element with selector, scrolls it into view if needed, and then uses Page.mouse to click in the center of the element. If there's no element matching selector, the method throws an error.
Parameter selector
selector to query the page for. CSS selectors can be passed as-is and a Puppeteer-specific selector syntax allows querying by text, a11y role and name, and xpath and combining these queries across shadow roots. Alternatively, you can specify the selector type using a prefix. If there are multiple elements satisfying the selector, the first will be clicked
Parameter options
Object
Returns
Promise which resolves when the element matching selector is successfully clicked. The Promise will be rejected if there is no element matching selector.
Remarks
Bear in mind that if click() triggers a navigation event and there's a separate page.waitForNavigation() promise to be resolved, you may end up with a race condition that yields unexpected results. The correct pattern for click and wait for navigation is the following:
const [response] = await Promise.all([ page.waitForNavigation(waitOptions), page.click(selector, clickOptions), ]);
Shortcut for page.mainFrame().click(selector[, options]).

method close

abstract close: (options?: { runBeforeUnload?: boolean }) => Promise<void>;

method content

content: () => Promise<string>;

The full HTML contents of the page, including the DOCTYPE.

method cookies

abstract cookies: (...urls: string[]) => Promise<Cookie[]>;

If no URLs are specified, this method returns cookies for the current page URL. If URLs are specified, only cookies for those URLs are returned.
Deprecated
Page-level cookie API is deprecated. Use Browser.cookies or BrowserContext.cookies instead.

method createCDPSession

Creates a Chrome Devtools Protocol session attached to the page.

method createPDFStream

abstract createPDFStream: (
    options?: PDFOptions
) => Promise<ReadableStream<Uint8Array>>;

Generates a PDF of the page with the print CSS media type.
Parameter options
options for generating the PDF.
Remarks
To generate a PDF with the screen media type, call `page.emulateMediaType('screen')` before calling page.pdf().
By default, page.pdf() generates a pdf with modified colors for printing. Use the `-webkit-print-color-adjust` property to force rendering of exact colors.

method deleteCookie

abstract deleteCookie: (...cookies: DeleteCookiesRequest[]) => Promise<void>;

Deprecated
Page-level cookie API is deprecated. Use Browser.deleteCookie, BrowserContext.deleteCookie, Browser.deleteMatchingCookies or BrowserContext.deleteMatchingCookies instead.

method emulate

emulate: (device: Device) => Promise<void>;

Emulates a given device's metrics and user agent.
To aid emulation, Puppeteer provides a list of known devices that can be via KnownDevices.
Remarks
This method is a shortcut for calling two methods: Page.setUserAgent and Page.setViewport.
This method will resize the page. A lot of websites don't expect phones to change size, so you should emulate before navigating to the page.
Example 1
import {KnownDevices} from 'puppeteer'; const iPhone = KnownDevices['iPhone 15 Pro']; const browser = await puppeteer.launch(); const page = await browser.newPage(); await page.emulate(iPhone); await page.goto('https://www.google.com'); // other actions... await browser.close();

method emulateIdleState

abstract emulateIdleState: (overrides?: {
    isUserActive: boolean;
    isScreenUnlocked: boolean;
}) => Promise<void>;

Emulates the idle state. If no arguments set, clears idle state emulation.

Parameter overrides

Mock idle state. If not set, clears idle overrides

Example 1

// set idle emulation
await page.emulateIdleState({isUserActive: true, isScreenUnlocked: false});

// do some checks here
...

// clear idle emulation
await page.emulateIdleState();

method emulateMediaFeatures

abstract emulateMediaFeatures: (features?: MediaFeature[]) => Promise<void>;

Parameter features

<?Array<Object>> Given an array of media feature objects, emulates CSS media features on the page. Each media feature object must have the following properties:

Example 1

await page.emulateMediaFeatures([
  {name: 'prefers-color-scheme', value: 'dark'},
]);
await page.evaluate(
  () => matchMedia('(prefers-color-scheme: dark)').matches,
);
// → true
await page.evaluate(
  () => matchMedia('(prefers-color-scheme: light)').matches,
);
// → false

await page.emulateMediaFeatures([
  {name: 'prefers-reduced-motion', value: 'reduce'},
]);
await page.evaluate(
  () => matchMedia('(prefers-reduced-motion: reduce)').matches,
);
// → true
await page.evaluate(
  () => matchMedia('(prefers-reduced-motion: no-preference)').matches,

  () => matchMedia('(prefers-color-scheme: light)').matches,
);
// → false
await page.evaluate(
  () => matchMedia('(prefers-reduced-motion: reduce)').matches,
);
// → true
await page.evaluate(
  () => matchMedia('(prefers-reduced-motion: no-preference)').matches,
);
// → false

await page.emulateMediaFeatures([{name: 'color-gamut', value: 'p3'}]);
await page.evaluate(() => matchMedia('(color-gamut: srgb)').matches);
// → true
await page.evaluate(() => matchMedia('(color-gamut: p3)').matches);
// → true
await page.evaluate(() => matchMedia('(color-gamut: rec2020)').matches);
// → false

method emulateMediaType

abstract emulateMediaType: (type?: string) => Promise<void>;

Parameter type

Changes the CSS media type of the page. The only allowed values are screen, print and null. Passing null disables CSS media emulation.

Example 1

await page.evaluate(() => matchMedia('screen').matches);

await page.evaluate(() => matchMedia('print').matches);
// → false

await page.emulateMediaType('print');
await page.evaluate(() => matchMedia('screen').matches);
// → false
await page.evaluate(() => matchMedia('print').matches);
// → true

await page.emulateMediaType(null);
await page.evaluate(() => matchMedia('screen').matches);
// → true
await page.evaluate(() => matchMedia('print').matches);
// → false

method emulateNetworkConditions

abstract emulateNetworkConditions: (
    networkConditions: NetworkConditions | null
) => Promise<void>;

This does not affect WebSockets and WebRTC PeerConnections (see https://crbug.com/563644). To set the page offline, you can use Page.setOfflineMode.

A list of predefined network conditions can be used by importing PredefinedNetworkConditions.

Parameter networkConditions

Passing null disables network condition emulation.

Example 1

import {PredefinedNetworkConditions} from 'puppeteer';
const slow3G = PredefinedNetworkConditions['Slow 3G'];

const browser = await puppeteer.launch();
const page = await browser.newPage();
await page.emulateNetworkConditions(slow3G);
await page.goto('https://www.google.com');
// other actions...
await browser.close();

method emulateTimezone

abstract emulateTimezone: (timezoneId?: string) => Promise<void>;

Parameter timezoneId
Changes the timezone of the page. See ICU’s metaZones.txt for a list of supported timezone IDs. Passing null disables timezone emulation.

abstract emulateVisionDeficiency: (
    type?: Protocol.Emulation.SetEmulatedVisionDeficiencyRequest
) => Promise<void>;

Simulates the given vision deficiency on the page.

Parameter type

the type of deficiency to simulate, or 'none' to reset.

Example 1

import puppeteer from 'puppeteer';

const browser = await puppeteer.launch();
const page = await browser.newPage();
await page.goto('https://v8.dev/blog/10-years');

await page.emulateVisionDeficiency('achromatopsia');
await page.screenshot({path: 'achromatopsia.png'});

await page.emulateVisionDeficiency('deuteranopia');
await page.screenshot({path: 'deuteranopia.png'});

await page.emulateVisionDeficiency('blurredVision');
await page.screenshot({path: 'blurred-vision.png'});

await page.emulateVisionDeficiency('reducedContrast');
await page.screenshot({path: 'reduced-contrast.png'});

await browser.close();

method evaluate

evaluate: <
    Params extends unknown[],
    Func extends EvaluateFunc<Params> = EvaluateFunc<Params>
>(
    pageFunction: Func | string,
    ...args: Params
) => Promise<Awaited<ReturnType<Func>>>;

Evaluates a function in the page's context and returns the result.
If the function passed to page.evaluate returns a Promise, the function will wait for the promise to resolve and return its value.
Parameter pageFunction
a function that is run within the page
Parameter args
arguments to be passed to the pageFunction
Returns
the return value of pageFunction.
Example 1
const result = await frame.evaluate(() => { return Promise.resolve(8 * 7); }); console.log(result); // prints "56"
You can pass a string instead of a function (although functions are recommended as they are easier to debug and use with TypeScript):
Example 2
const aHandle = await page.evaluate('1 + 2');
To get the best TypeScript experience, you should pass in as the generic the type of pageFunction:
const aHandle = await page.evaluate(() => 2);
Example 3
ElementHandle instances (including JSHandles) can be passed as arguments to the pageFunction:
const bodyHandle = await page.$('body'); const html = await page.evaluate(body => body.innerHTML, bodyHandle); await bodyHandle.dispose();

method evaluateHandle

evaluateHandle: <
    Params extends unknown[],
    Func extends EvaluateFunc<Params> = EvaluateFunc<Params>
>(
    pageFunction: Func | string,
    ...args: Params
) => Promise<HandleFor<Awaited<ReturnType<Func>>>>;

Parameter pageFunction
a function that is run within the page
Parameter args
arguments to be passed to the pageFunction
Remarks
The only difference between page.evaluate and page.evaluateHandle is that evaluateHandle will return the value wrapped in an in-page object.
If the function passed to page.evaluateHandle returns a Promise, the function will wait for the promise to resolve and return its value.
You can pass a string instead of a function (although functions are recommended as they are easier to debug and use with TypeScript):
Example 1
const aHandle = await page.evaluateHandle('document');
Example 2
JSHandle instances can be passed as arguments to the pageFunction:
const aHandle = await page.evaluateHandle(() => document.body); const resultHandle = await page.evaluateHandle( body => body.innerHTML, aHandle, ); console.log(await resultHandle.jsonValue()); await resultHandle.dispose();
Most of the time this function returns a JSHandle, but if pageFunction returns a reference to an element, you instead get an ElementHandle back:
Example 3
const button = await page.evaluateHandle(() => document.querySelector('button'), ); // can call `click` because `button` is an `ElementHandle` await button.click();
The TypeScript definitions assume that evaluateHandle returns a JSHandle, but if you know it's going to return an ElementHandle, pass it as the generic argument:
const button = await page.evaluateHandle<ElementHandle>(...);

method evaluateOnNewDocument

abstract evaluateOnNewDocument: <
    Params extends unknown[],
    Func extends (...args: Params) => unknown = (...args: Params) => unknown
>(
    pageFunction: Func | string,
    ...args: Params
) => Promise<NewDocumentScriptEvaluation>;

Adds a function which would be invoked in one of the following scenarios:
- whenever the page is navigated
- whenever the child frame is attached or navigated. In this case, the function is invoked in the context of the newly attached frame.
The function is invoked after the document was created but before any of its scripts were run. This is useful to amend the JavaScript environment, e.g. to seed Math.random.
Parameter pageFunction
Function to be evaluated in browser context
Parameter args
Arguments to pass to pageFunction
Example 1
An example of overriding the navigator.languages property before the page loads:
// preload.js // overwrite the `languages` property to use a custom getter Object.defineProperty(navigator, 'languages', { get: function () { return ['en-US', 'en', 'bn']; }, }); // In your puppeteer script, assuming the preload.js file is // in same folder of our script. const preloadFile = fs.readFileSync('./preload.js', 'utf8'); await page.evaluateOnNewDocument(preloadFile);

method exposeFunction

abstract exposeFunction: (
    name: string,
    pptrFunction: Function | { default: Function }
) => Promise<void>;

If the puppeteerFunction returns a Promise, it will be awaited.

:::note

Functions installed via page.exposeFunction survive navigations.

:::

Parameter name

Name of the function on the window object

Parameter pptrFunction

Callback function which will be called in Puppeteer's context.

Example 1

An example of adding an md5 function into the page:

import puppeteer from 'puppeteer';
import crypto from 'crypto';

const browser = await puppeteer.launch();
const page = await browser.newPage();
page.on('console', msg => console.log(msg.text()));
await page.exposeFunction('md5', text =>
  crypto.createHash('md5').update(text).digest('hex'),
);
await page.evaluate(async () => {
  // use window.md5 to compute hashes
  const myString = 'PUPPETEER';
  const myHash = await window.md5(myString);
  console.log(`md5 of ${myString} is ${myHash}`);
});
await browser.close();

Example 2

An example of adding a window.readfile function into the page:

import puppeteer from 'puppeteer';
import fs from 'node:fs';

const browser = await puppeteer.launch();
const page = await browser.newPage();
page.on('console', msg => console.log(msg.text()));
await page.exposeFunction('readfile', async filePath => {
  return new Promise((resolve, reject) => {
    fs.readFile(filePath, 'utf8', (err, text) => {
      if (err) reject(err);
      else resolve(text);
    });
  });
});
await page.evaluate(async () => {
  // use window.readfile to read contents of a file
  const content = await window.readfile('/etc/hosts');
  console.log(content);
});
await browser.close();

method focus

Parameter selector
selector to query the page for. CSS selectors can be passed as-is and a Puppeteer-specific selector syntax allows querying by text, a11y role and name, and xpath and combining these queries across shadow roots. Alternatively, you can specify the selector type using a prefix. If there are multiple elements satisfying the selector, the first will be hovered.

NOTE: CSP bypassing happens at the moment of CSP initialization rather than evaluation. Usually, this means that page.setBypassCSP should be called before navigating to the domain.

method setBypassServiceWorker

abstract setBypassServiceWorker: (bypass: boolean) => Promise<void>;

Toggles ignoring of service worker for each request.
Parameter bypass
Whether to bypass service worker and load from network.

method setCacheEnabled

- page.reload(options)
- page.setContent(html,options)
- page.waitForNavigation(options)
Parameter timeout
Maximum navigation time in milliseconds.

method setDefaultTimeout

abstract setDefaultTimeout: (timeout: number) => void;

Parameter timeout
Maximum time in milliseconds.

method setDragInterception

abstract setDragInterception: (enabled: boolean) => Promise<void>;

Parameter enabled
Whether to enable drag interception.
Deprecated
We no longer support intercepting drag payloads. Use the new drag APIs found on ElementHandle to drag (or just use the Page.mouse).

method setExtraHTTPHeaders

abstract setExtraHTTPHeaders: (headers: Record<string, string>) => Promise<void>;

The extra HTTP headers will be sent with every request the page initiates.
:::tip
All HTTP header names are lowercased. (HTTP headers are case-insensitive, so this shouldn’t impact your server code.)
:::
:::note
page.setExtraHTTPHeaders does not guarantee the order of headers in the outgoing requests.
:::
Parameter headers
An object containing additional HTTP headers to be sent with every request. All header values must be strings.

method setGeolocation

abstract setGeolocation: (options: GeolocationOptions) => Promise<void>;

Sets the page's geolocation.
Remarks
Consider using BrowserContext.overridePermissions to grant permissions for the page to read its geolocation.
Example 1
await page.setGeolocation({latitude: 59.95, longitude: 30.31667});

method setJavaScriptEnabled

abstract setJavaScriptEnabled: (enabled: boolean) => Promise<void>;

Parameter enabled
Whether or not to enable JavaScript on the page.
Remarks
NOTE: changing this value won't affect scripts that have already been run. It will take full effect on the next navigation.

method setOfflineMode

abstract setOfflineMode: (enabled: boolean) => Promise<void>;

Emulates the offline mode.
It does not change the download/upload/latency parameters set by Page.emulateNetworkConditions
Parameter enabled
When true, enables offline mode for the page.

method setRequestInterception

abstract setRequestInterception: (value: boolean) => Promise<void>;

Activating request interception enables HTTPRequest.abort, HTTPRequest.continue and HTTPRequest.respond methods. This provides the capability to modify network requests that are made by a page.
Once request interception is enabled, every request will stall unless it's continued, responded or aborted; or completed using the browser cache.
See the Request interception guide for more details.
Parameter value
Whether to enable request interception.
Example 1
An example of a naïve request interceptor that aborts all image requests:
import puppeteer from 'puppeteer'; const browser = await puppeteer.launch(); const page = await browser.newPage(); await page.setRequestInterception(true); page.on('request', interceptedRequest => { if ( interceptedRequest.url().endsWith('.png') || interceptedRequest.url().endsWith('.jpg') ) interceptedRequest.abort(); else interceptedRequest.continue(); }); await page.goto('https://example.com'); await browser.close();

method setUserAgent

abstract setUserAgent: {
    (
        userAgent: string,
        userAgentMetadata?: Protocol.Emulation.UserAgentMetadata
    ): Promise<void>;
    (options: {
        userAgent?: string;
        userAgentMetadata?: Protocol.Emulation.UserAgentMetadata;
        platform?: string;
    }): Promise<void>;
};

Parameter userAgent
Specific user agent to use in this page
Parameter userAgentData
Specific user agent client hint data to use in this page
Returns
Promise which resolves when the user agent is set.
Deprecated
Use Page.setUserAgent instead.
Parameter options
Object containing user agent and optional user agent metadata
Returns
Promise which resolves when the user agent is set.

method setViewport

abstract setViewport: (viewport: Viewport | null) => Promise<void>;

page.setViewport will resize the page. A lot of websites don't expect phones to change size, so you should set the viewport before navigating to the page.
In the case of multiple pages in a single browser, each page can have its own viewport size. Setting the viewport to null resets the viewport to its default value.
Parameter viewport
Remarks
NOTE: in certain cases, setting viewport will reload the page in order to set the isMobile or hasTouch properties.
Example 1
const page = await browser.newPage(); await page.setViewport({ width: 640, height: 480, deviceScaleFactor: 1, }); await page.goto('https://example.com');

method tap

tap: (selector: string) => Promise<void>;

This method fetches an element with selector, scrolls it into view if needed, and then uses Page.touchscreen to tap in the center of the element. If there's no element matching selector, the method throws an error.
Parameter selector
selector to query the page for. CSS selectors can be passed as-is and a Puppeteer-specific selector syntax allows querying by text, a11y role and name, and xpath and combining these queries across shadow roots. Alternatively, you can specify the selector type using a prefix. If there are multiple elements satisfying the selector, the first will be tapped.
Remarks
Shortcut for page.mainFrame().tap(selector).

method target

abstract target: () => Target;

A target this page was created from.
Deprecated
Use Page.createCDPSession directly.

method title

title: () => Promise<string>;

The page's title
Remarks
Shortcut for page.mainFrame().title().

method type

type: (
    selector: string,
    text: string,
    options?: Readonly<KeyboardTypeOptions>
) => Promise<void>;

Sends a keydown, keypress/input, and keyup event for each character in the text.
To press a special key, like Control or ArrowDown, use Keyboard.press.
Parameter selector
selector to query the page for. CSS selectors can be passed as-is and a Puppeteer-specific selector syntax allows querying by text, a11y role and name, and xpath and combining these queries across shadow roots. Alternatively, you can specify the selector type using a prefix.
Parameter text
A text to type into a focused element.
Parameter options
have property delay which is the Time to wait between key presses in milliseconds. Defaults to 0.
Returns
Example 1
await page.type('#mytextarea', 'Hello'); // Types instantly await page.type('#mytextarea', 'World', {delay: 100}); // Types slower, like a user

method url

url: () => string;

The page's URL.
Remarks
Shortcut for page.mainFrame().url().

method viewport

abstract viewport: () => Viewport | null;

Returns the current page viewport settings without checking the actual page viewport.
This is either the viewport set with the previous Page.setViewport call or the default viewport set via ConnectOptions.defaultViewport.

method waitForDevicePrompt

abstract waitForDevicePrompt: (
    options?: WaitTimeoutOptions
) => Promise<DeviceRequestPrompt>;

This method is typically coupled with an action that triggers a device request from an api such as WebBluetooth.
:::caution
This must be called before the device request is made. It will not return a currently active device prompt.
:::
Example 1
const [devicePrompt] = Promise.all([ page.waitForDevicePrompt(), page.click('#connect-bluetooth'), ]); await devicePrompt.select( await devicePrompt.waitForDevice(({name}) => name.includes('My Device')), );

method waitForFileChooser

abstract waitForFileChooser: (
    options?: WaitTimeoutOptions
) => Promise<FileChooser>;

This method is typically coupled with an action that triggers file choosing.
:::caution
This must be called before the file chooser is launched. It will not return a currently active file chooser.
:::
:::caution
Interception of file dialogs triggered via DOM APIs such as window.showOpenFilePicker is currently not supported.
:::
Remarks
In the "headful" browser, this method results in the native file picker dialog not showing up for the user.
Example 1
The following example clicks a button that issues a file chooser and then responds with /tmp/myfile.pdf as if a user has selected this file.
const [fileChooser] = await Promise.all([ page.waitForFileChooser(), page.click('#upload-file-button'), // some button that triggers file selection ]); await fileChooser.accept(['/tmp/myfile.pdf']);

method waitForFrame

waitForFrame: (
    urlOrPredicate: string | ((frame: Frame) => Awaitable<boolean>),
    options?: WaitTimeoutOptions
) => Promise<Frame>;

Waits for a frame matching the given conditions to appear.

Example 1

const frame = await page.waitForFrame(async frame => {
  const frameElement = await frame.frameElement();
  if (!frameElement) {
    return false;
  }
  const name = await frameElement.evaluate(el => el.getAttribute('name'));
  return name === 'test';
});

method waitForFunction

waitForFunction: <
    Params extends unknown[],
    Func extends EvaluateFunc<Params> = EvaluateFunc<Params>
>(
    pageFunction: Func | string,
    options?: FrameWaitForFunctionOptions,
    ...args: Params
) => Promise<HandleFor<Awaited<ReturnType<Func>>>>;

Waits for the provided function, pageFunction, to return a truthy value when evaluated in the page's context.

Parameter pageFunction

Function to be evaluated in browser context until it returns a truthy value.

Parameter options

Options for configuring waiting behavior.

Example 1

Page.waitForFunction can be used to observe a viewport size change:

import puppeteer from 'puppeteer';

const browser = await puppeteer.launch();
const page = await browser.newPage();
const watchDog = page.waitForFunction('window.innerWidth < 100');
await page.setViewport({width: 50, height: 50});
await watchDog;
await browser.close();

Example 2

Arguments can be passed from Node.js to pageFunction:

const selector = '.foo';
await page.waitForFunction(
  selector => !!document.querySelector(selector),
  {},
  selector,
);

Example 3

The provided pageFunction can be asynchronous:

const username = 'github-username';
await page.waitForFunction(
  async username => {
    const githubResponse = await fetch(
      `https://api.github.com/users/${username}`,
    );
    const githubUser = await githubResponse.json();
    // show the avatar
    const img = document.createElement('img');
    img.src = githubUser.avatar_url;
    // wait 3 seconds
    await new Promise((resolve, reject) => setTimeout(resolve, 3000));
    img.remove();
  },
  {},
  username,
);

method waitForNavigation

waitForNavigation: (options?: WaitForOptions) => Promise<HTTPResponse | null>;

Waits for the page to navigate to a new URL or to reload. It is useful when you run code that will indirectly cause the page to navigate.
Parameter options
Navigation parameters which might have the following properties:
Returns
A Promise which resolves to the main resource response.
- In case of multiple redirects, the navigation will resolve with the response of the last redirect. - In case of navigation to a different anchor or navigation due to History API usage, the navigation will resolve with null.
Remarks
Usage of the History API to change the URL is considered a navigation.
Example 1
const [response] = await Promise.all([ page.waitForNavigation(), // The promise resolves after navigation has finished page.click('a.my-link'), // Clicking the link will indirectly cause a navigation ]);

method waitForNetworkIdle

waitForNetworkIdle: (options?: WaitForNetworkIdleOptions) => Promise<void>;

Waits for the network to be idle.
Parameter options
Options to configure waiting behavior.
Returns
A promise which resolves once the network is idle.
Remarks

A URL or predicate to wait for
Parameter options
Optional waiting parameters
Returns
Promise which resolves to the matched request
Remarks
Optional Waiting Parameters have:
- timeout: Maximum wait time in milliseconds, defaults to 30 seconds, pass 0 to disable the timeout. The default value can be changed by using the Page.setDefaultTimeout method.
- signal: A signal object that allows you to cancel a waitForRequest call.
Example 1
const firstRequest = await page.waitForRequest( 'https://example.com/resource', ); const finalRequest = await page.waitForRequest( request => request.url() === 'https://example.com', ); return finalRequest.response()?.ok();

Remarks
Optional Parameter have:
- timeout: Maximum wait time in milliseconds, defaults to 30 seconds, pass 0 to disable the timeout. The default value can be changed by using the Page.setDefaultTimeout method.
- signal: A signal object that allows you to cancel a waitForResponse call.
Example 1
const firstResponse = await page.waitForResponse( 'https://example.com/resource', ); const finalResponse = await page.waitForResponse( response => response.url() === 'https://example.com' && response.status() === 200, ); const finalResponse = await page.waitForResponse(async response => { return (await response.text()).includes('<html>'); }); return finalResponse.ok();

method waitForSelector

waitForSelector: <Selector extends string>(
    selector: Selector,
    options?: WaitForSelectorOptions
) => Promise<ElementHandle<NodeFor<Selector>> | null>;

Wait for the selector to appear in page. If at the moment of calling the method the selector already exists, the method will return immediately. If the selector doesn't appear after the timeout milliseconds of waiting, the function will throw.
Parameter selector
selector to query the page for. CSS selectors can be passed as-is and a Puppeteer-specific selector syntax allows querying by text, a11y role and name, and xpath and combining these queries across shadow roots. Alternatively, you can specify the selector type using a prefix.
Parameter options
Optional waiting parameters
Returns
Promise which resolves when element specified by selector string is added to DOM. Resolves to null if waiting for hidden: true and selector is not found in DOM.
Remarks
The optional Parameter in Arguments options are:
- visible: A boolean wait for element to be present in DOM and to be visible, i.e. to not have display: none or visibility: hidden CSS properties. Defaults to false.

- @public

class PuppeteerNode

class PuppeteerNode extends Puppeteer {}

Extends the main Puppeteer class with Node specific behaviour for fetching and downloading browsers.
If you're using Puppeteer in a Node environment, this is the class you'll get when you run require('puppeteer') (or the equivalent ES import).
Remarks
The most common method to use is launch, which is used to launch and connect to a new browser instance.

Remarks
Puppeteer can also be used to control the Chrome browser, but it works best with the version of Chrome for Testing downloaded by default. There is no guarantee it will work with any other version. If Google Chrome (rather than Chrome for Testing) is preferred, a Chrome Canary or Dev Channel build is suggested. See this article for a description of the differences between Chromium and Chrome. This article describes some differences for Linux users. See this doc for the description of Chrome for Testing.
Example 1
You can use options.ignoreDefaultArgs to filter out --mute-audio from default arguments:

) => Promise<Awaited<ReturnType<Func>>>;

Evaluates a given function in the worker.
Parameter func
Function to be evaluated.
Parameter args
Arguments to pass into func.
Returns
The result of func.
Remarks
If the given function returns a promise, evaluate will wait for the promise to resolve.
As a rule of thumb, if the return value of the given function is more complicated than a JSON object (e.g. most classes), then evaluate will _likely_ return some truncated value (or {}). This is because we are not returning the actual return value, but a deserialized version as a result of transferring the return value through a protocol to Puppeteer.
In general, you should use evaluateHandle if evaluate cannot serialize the return value properly or you need a mutable handle to the return object.

method evaluateHandle

evaluateHandle: <
    Params extends unknown[],
    Func extends EvaluateFunc<Params> = EvaluateFunc<Params>
>(
    func: Func | string,
    ...args: Params
) => Promise<HandleFor<Awaited<ReturnType<Func>>>>;

Evaluates a given function in the worker.
Parameter func
Function to be evaluated.
Parameter args
Arguments to pass into func.
Returns
A handle to the return value of func.
Remarks
If the given function returns a promise, evaluate will wait for the promise to resolve.
In general, you should use evaluateHandle if evaluate cannot serialize the return value properly or you need a mutable handle to the return object.

interface BluetoothEmulation

interface BluetoothEmulation {}

Exposes the bluetooth emulation abilities.
Remarks
Web Bluetooth specification requires the emulated adapters should be isolated per top-level navigable. However, at the moment Chromium's bluetooth emulation implementation is tight to the browser context, not the page.
