    ) => GraphQLHandler;

    put: HttpRequestHandler;
    delete: HttpRequestHandler;
    patch: HttpRequestHandler;

Functions

function bypass

bypass: (input: BypassRequestInput, init?: RequestInit) => Request;

Creates a Request instance that will always be ignored by MSW.
Example 1
import { bypass } from 'msw'
fetch(bypass('/resource')) fetch(bypass(new URL('/resource', 'https://example.com))) fetch(bypass(new Request('https://example.com/resource')))
See Also

function cleanUrl

cleanUrl: (path: string) => string;

Removes search parameters and the fragment from a given URL string.

function delay

delay: (durationOrMode?: DelayMode | number) => Promise<void>;

Delays the response by the given duration (ms).
Example 1
await delay() // emulate realistic server response time await delay(1200) // delay response by 1200ms await delay('infinite') // delay response infinitely
See Also

function getResponse

getResponse: (
    handlers: Array<RequestHandler>,
    request: Request,
    resolutionContext?: ResponseResolutionContext
) => Promise<Response | undefined>;

Finds a response for the given request instance in the array of request handlers.
Parameter handlers
The array of request handlers.
Parameter request
The Request instance.
Parameter resolutionContext
Request resolution options.
Returns
{Response} A mocked response, if any.

function handleRequest

handleRequest: (
    request: Request,
    requestId: string,
    handlers: Array<RequestHandler>,
    options: RequiredDeep<SharedOptions>,
    emitter: Emitter<LifeCycleEventsMap>,
    handleRequestOptions?: HandleRequestOptions
) => Promise<Response | undefined>;

function isCommonAssetRequest

isCommonAssetRequest: (request: Request) => boolean;

Determines if the given request is a static asset request. Useful when deciding which unhandled requests to ignore. Despite being ignored, you can still intercept and mock static assets by creating request handlers for them.
Example 1
import { isCommonAssetRequest } from 'msw'
await worker.start({ onUnhandledRequest(request, print) { if (!isCommonAssetRequest(request)) { print.warning() } } })

function matchRequestUrl

matchRequestUrl: (url: URL, path: Path, baseUrl?: string) => Match;

Returns the result of matching given request URL against a mask.

function onUnhandledRequest

onUnhandledRequest: (
    request: Request,
    strategy?: UnhandledRequestStrategy
) => Promise<void>;

function passthrough

passthrough: () => HttpResponse<any>;

Performs the intercepted request as-is.
This stops request handler lookup so no other handlers can affect this request past this point. Unlike bypass(), this will not trigger an additional request.
Example 1
http.get('/resource', () => { return passthrough() })

method text

static text: <BodyType extends string>(
    body?: NoInfer<BodyType> | null,
