Functions

function bootstrapApplication

bootstrapApplication: (
    rootComponent: Type<unknown>,
    options?: ApplicationConfig,
    context?: BootstrapContext
) => Promise<ApplicationRef>;

Bootstraps an instance of an Angular application and renders a standalone component as the application's root component. More information about standalone components can be found in [this guide](guide/components/importing).
The root component passed into this function **must** be a standalone one
@Component({ template: 'Hello world!' }) class Root {} const appRef: ApplicationRef = await bootstrapApplication(Root);
You can add the list of providers that should be available in the application injector by specifying the providers field in an object passed as the second argument:
await bootstrapApplication(Root, { providers: [ {provide: BACKEND_URL, useValue: 'https://yourdomain.com/api'} ] });
The importProvidersFrom helper method can be used to collect all providers from any existing NgModule (and transitively from all NgModules that it imports):
await bootstrapApplication(Root, { providers: [ importProvidersFrom(SomeNgModule) ] });
Note: the bootstrapApplication method doesn't include [Testability](api/core/Testability) by default. You can add [Testability](api/core/Testability) by getting the list of necessary providers using provideProtractorTestingSupport() function and adding them into the providers array, for example:
import {provideProtractorTestingSupport} from '@angular/platform-browser'; await bootstrapApplication(Root, {providers: [provideProtractorTestingSupport()]});
Parameter rootComponent
A reference to a standalone component that should be rendered.
Parameter options
Extra configuration for the bootstrap operation, see ApplicationConfig for additional info.
Parameter context
Optional context object that can be used to provide a pre-existing platform injector. This is useful for advanced use-cases, for example, server-side rendering, where the platform is created for each request.
Returns
A promise that returns an ApplicationRef instance once resolved.

function createApplication

createApplication: (
    options?: ApplicationConfig,
    context?: BootstrapContext
) => Promise<ApplicationRef>;

Create an instance of an Angular application without bootstrapping any components. This is useful for the situation where one wants to decouple application environment creation (a platform and associated injectors) from rendering components on a screen. Components can be subsequently bootstrapped on the returned ApplicationRef.
Parameter options
Extra configuration for the application environment, see ApplicationConfig for additional info.
Parameter context
Optional context object that can be used to provide a pre-existing platform injector. This is useful for advanced use-cases, for example, server-side rendering, where the platform is created for each request.
Returns
A promise that returns an ApplicationRef instance once resolved.

function disableDebugTools

disableDebugTools: () => void;

Disables Angular tools.

function enableDebugTools

enableDebugTools: <T>(ref: ComponentRef<T>) => ComponentRef<T>;

Enabled Angular debug tools that are accessible via your browser's developer console.
Usage:
1. Open developer console (e.g. in Chrome Ctrl + Shift + j) 1. Type ng. (usually the console will show auto-complete suggestion) 1. Try the change detection profiler ng.profiler.timeChangeDetection() then hit Enter.

function platformBrowser

platformBrowser: (extraProviders?: StaticProvider[]) => PlatformRef;

A factory function that returns a PlatformRef instance associated with browser service providers.

function provideClientHydration

provideClientHydration: (
    ...features: HydrationFeature<HydrationFeatureKind>[]
) => EnvironmentProviders;

Sets up providers necessary to enable hydration functionality for the application.
By default, the function enables the recommended set of features for the optimal performance for most of the applications. It includes the following features:
* Reconciling DOM hydration. Learn more about it [here](guide/hydration). * [HttpClient](api/common/http/HttpClient) response caching while running on the server and transferring this cache to the client to avoid extra HTTP requests. Learn more about data caching [here](guide/ssr#caching-data-when-using-httpclient). Incremental hydration. [Learn more](guide/incremental-hydration).
These functions allow you to disable some of the default features or enable new ones:
* withNoHttpTransferCache to disable HTTP transfer cache * withHttpTransferCacheOptions to configure some HTTP transfer cache options * withI18nSupport to enable hydration support for i18n blocks * withEventReplay to enable support for replaying user events * withNoIncrementalHydration to disable incremental hydration
Basic example of how you can enable hydration in your application when bootstrapApplication function is used:
bootstrapApplication(App, { providers: [provideClientHydration()] });
Alternatively if you are using NgModules, you would add provideClientHydration to your root app module's provider list.
@NgModule({ declarations: [RootCmp], bootstrap: [RootCmp], providers: [provideClientHydration()], }) export class AppModule {}
Parameter features
Optional features to configure additional hydration behaviors.
Returns
A set of providers to enable hydration.
17.0
See Also

function provideProtractorTestingSupport

provideProtractorTestingSupport: (options?: {
    usePendingTasksForStability?: boolean;
}) => Provider[];

Returns a set of providers required to setup [Testability](api/core/Testability) for an application bootstrapped using the bootstrapApplication function. The set of providers is needed to support testing an application with Protractor (which relies on the Testability APIs to be present).
Returns
An array of providers required to setup Testability for an application and make it available for testing using Protractor.

function withEventReplay

withEventReplay: () => HydrationFeature<HydrationFeatureKind.EventReplay>;

Enables support for replaying user events (e.g. clicks) that happened on a page before hydration logic has completed. Once an application is hydrated, all captured events are replayed and relevant event listeners are executed.
Basic example of how you can enable event replay in your application when bootstrapApplication function is used:
bootstrapApplication(App, { providers: [provideClientHydration(withEventReplay())] });
See Also
- provideClientHydration

function withHttpTransferCacheOptions

withHttpTransferCacheOptions: (
    options: HttpTransferCacheOptions
) => HydrationFeature<HydrationFeatureKind.HttpTransferCacheOptions>;

The function accepts an object, which allows to configure cache parameters, such as which headers should be included (no headers are included by default), whether POST requests should be cached or a callback function to determine if a particular request should be cached.
See Also
- [Configuring HTTP transfer cache options](guide/ssr#caching-data-when-using-httpclient)

function withI18nSupport

withI18nSupport: () => HydrationFeature<HydrationFeatureKind.I18nSupport>;

Enables support for hydrating i18n blocks.
20.0

function withIncrementalHydration

withIncrementalHydration: () => HydrationFeature<HydrationFeatureKind.IncrementalHydration>;

Enables support for incremental hydration using the hydrate trigger syntax.
Basic example of how you can enable incremental hydration in your application when the bootstrapApplication function is used:
bootstrapApplication(App, { providers: [provideClientHydration(withIncrementalHydration())] });
20.0
See Also
- provideClientHydration
Deprecated
Since v22.0.0, incremental hydration is enabled by default with provideClientHydration. Intent to remove in v24.

function withNoHttpTransferCache

withNoHttpTransferCache: () => HydrationFeature<HydrationFeatureKind.NoHttpTransferCache>;

Disables HTTP transfer cache. Effectively causes HTTP requests to be performed twice: once on the server and other one on the browser.
See Also
- [Disabling Caching](guide/ssr#disabling-caching)

function withNoIncrementalHydration

withNoIncrementalHydration: () => HydrationFeature<HydrationFeatureKind.NoIncrementalHydration>;

Disables support for incremental hydration (which is enabled by default).
22.0

class DomSanitizer

abstract class DomSanitizer implements Sanitizer {}

DomSanitizer helps preventing Cross Site Scripting Security bugs (XSS) by sanitizing values to be safe to use in the different DOM contexts.
For example, when binding a URL in an <a [href]="someValue"> hyperlink, someValue will be sanitized so that an attacker cannot inject e.g. a javascript: URL that would execute code on the website.
In specific situations, it might be necessary to disable sanitization, for example if the application genuinely needs to produce a javascript: style link with a dynamic value in it. Users can bypass security by constructing a value with one of the bypassSecurityTrust... methods, and then binding to that value from the template.
These situations should be very rare, and extraordinary care must be taken to avoid creating a Cross Site Scripting (XSS) security bug!
When using bypassSecurityTrust..., make sure to call the method as early as possible and as close as possible to the source of the value, to make it easy to verify no security bug is created by its use.
It is not required (and not recommended) to bypass security if the value is safe, e.g. a URL that does not start with a suspicious protocol, or an HTML snippet that does not contain dangerous code. The sanitizer leaves safe values intact.
Calling any of the bypassSecurityTrust... APIs disables Angular's built-in sanitization for the value passed in. Carefully check and audit all values and code paths going into this call. Make sure any user data is appropriately escaped for this security context. For more detail, see the [Security Guide](https://g.co/ng/security).

property ɵfac

static ɵfac: i0.ɵɵFactoryDeclaration<DomSanitizer, never>;

property ɵprov

static ɵprov: i0.ɵɵInjectableDeclaration<DomSanitizer>;

method bypassSecurityTrustHtml

abstract bypassSecurityTrustHtml: (value: string) => SafeHtml;

Bypass security and trust the given value to be safe HTML. Only use this when the bound HTML is unsafe (e.g. contains <script> tags) and the code should be executed. The sanitizer will leave safe HTML intact, so in most situations this method should not be used.
**WARNING:** calling this method with untrusted user data exposes your application to XSS security risks!

method bypassSecurityTrustResourceUrl

abstract bypassSecurityTrustResourceUrl: (value: string) => SafeResourceUrl;

Bypass security and trust the given value to be a safe resource URL, i.e. a location that may be used to load executable code from, like <script src>, or <iframe src>.
**WARNING:** calling this method with untrusted user data exposes your application to XSS security risks!

method bypassSecurityTrustScript

abstract bypassSecurityTrustScript: (value: string) => SafeScript;

Bypass security and trust the given value to be safe JavaScript.
**WARNING:** calling this method with untrusted user data exposes your application to XSS security risks!

method bypassSecurityTrustStyle

abstract bypassSecurityTrustStyle: (value: string) => SafeStyle;

Bypass security and trust the given value to be safe style value (CSS).
**WARNING:** calling this method with untrusted user data exposes your application to XSS security risks!

method bypassSecurityTrustUrl

abstract bypassSecurityTrustUrl: (value: string) => SafeUrl;

Bypass security and trust the given value to be a safe style URL, i.e. a value that can be used in hyperlinks or <img src>.
**WARNING:** calling this method with untrusted user data exposes your application to XSS security risks!

method sanitize

abstract sanitize: (
    context: SecurityContext,
    value: SafeValue | string | null
) => string | null;

Gets a safe value from either a known safe value or a value with unknown safety.
If the given value is already a SafeValue, this method returns the unwrapped value. If the security context is HTML and the given value is a plain string, this method sanitizes the string, removing any potentially unsafe content. For any other security context, this method throws an error if provided with a plain string.

class Meta

class Meta {}

A service for managing HTML <meta> tags.
Properties of the MetaDefinition object match the attributes of the HTML <meta> tag. These tags define document metadata that is important for things like configuring a Content Security Policy, defining browser compatibility and security settings, setting HTTP Headers, defining rich content for social sharing, and Search Engine Optimization (SEO).
To identify specific <meta> tags in a document, use an attribute selection string in the format "tag_attribute='value string'". For example, an attrSelector value of "name='description'" matches a tag whose name attribute has the value "description". Selectors are used with the querySelector() Document method, in the format meta[{attrSelector}].
