This Fetch API interface represents a resource request.
cache: RequestCache
Returns the cache mode associated with request, which is a string indicating how the request will interact with the browser's cache when fetching.
credentials: RequestCredentials
Returns the credentials mode associated with request, which is a string indicating whether credentials will be sent with the request always, never, or only when sent to a same-origin URL.
destination: RequestDestination
Returns the kind of resource requested by request, e.g., "document" or "script".
Returns a Headers object consisting of the headers associated with request. Note that headers added in the network layer by the user agent will not be accounted for in this object, e.g., the "Host" header.
integrity: string
Returns request's subresource integrity metadata, which is a cryptographic hash of the resource being fetched. Its value consists of multiple hashes separated by whitespace. [SRI]
keepalive: boolean
Returns a boolean indicating whether or not request can outlive the global in which it was created.
method: string
Returns request's HTTP method, which is "GET" by default.
mode: RequestMode
Returns the mode associated with request, which is a string indicating whether the request will use CORS, or will be restricted to same-origin URLs.
redirect: RequestRedirect
Returns the redirect mode associated with request, which is a string indicating how redirects for the request will be handled during fetching. A request will follow redirects by default.
referrer: string
Returns the referrer of request. Its value can be a same-origin URL if
explicitly set in init, the empty string to indicate no referrer, and
"about:client" when defaulting to the global's default. This is used during
fetching to determine the value of the Referer header of the request
being made.
referrerPolicy: ReferrerPolicy
Returns the referrer policy associated with request. This is used during fetching to compute the value of the request's referrer.
signal: AbortSignal
Returns the signal associated with request, which is an AbortSignal object indicating whether or not request has been aborted, and its abort event handler.
