Replaces the remaining hand-rolled deferred promise implementations
with the native `Promise.withResolvers()` API and removes the now
unused helper and import.
Follow-up to #69739.
Cancel the unread response body before reporting NG02825 when its declared Content-Length exceeds the configured buffer limit. Without cancellation, SSR can finish while the underlying connection remains open.
Add regression coverage for the declared-length rejection path.
Prevent AbortController.abort() from executing during Observable teardown when a FetchBackend HTTP request has already completed successfully or errored.
Previously, FetchBackend unconditionally called abort() upon stream termination. When requests completed normally, calling abort() after delivery caused Chromium-based browsers to mark the resolved request as net::ERR_ABORTED in DevTools due to a race condition, leading to missing response body payloads ("Failed to load response data"). By tracking whether the request has already settled—similar to XhrBackend checking for xhr.readyState !== xhr.DONE—we ensure abort() is only called for unsettled, in-flight requests upon unsubscription.
Fixes#70071
Extract the charset parameter from the Content-Type response header in FetchBackend and pass it to TextDecoder when decoding text and json responses. When no valid charset is provided or supported, gracefully fall back to default utf-8 decoding.
Fixes#70061
By default, the `FetchBackend` on SSR will limit the response body size to 10 MB.
If the response body exceeds this limit, an error will be thrown.
This default value can be configured by providing by setting the `maxResponseBodySize` in `provideServerRendering`.
This is to prevent DoS on the server when loading large files
In order to raise an error on upload progress on the `FetchBackend`, we split `reportProgress` into 2 respective properties.
DEPRECATED: The `reportProgress` option is deprecated please use `reportUploadProgress` & `reportDownloadProgress` instead.
This commit replaces the `XhrHttpBackend` with the `FetchBackend` as the default implementation of the `HttpBackend`.
This introduces a breaking change a the `FetchBackend` does not support the report progress for uploads.
The previous behavior (`HttpXhrBackend`) can be restored by setting `withXhr()` in the `provideHttpClient()` provider function.
DEPRECATED: `withFetch` is now deprecated, it can be safely removed.
BREAKING CHANGE: Use the `HttpXhrBackend` with `provideHttpClient(withXhr)` if you want to keep supporting upload progress reports.
Introduces a referrer policy option for HTTP requests to allow specifying the referrer information sent, improving privacy and security controls.

This commit drops the `X-Request-URL` header. It was a non-standard HTTP response header, deprecated long ago and never part of any official specification. Modern browsers now expose the final URL via the `XMLHttpRequest.responseURL` property, as defined in the WHATWG spec.

The fetch backend now propagates the plain body when parsing the body fails.
This replicates the behavior of the XHR backend introduced in #19773.
The current state completely obfuscates errors of the "wrong" response type.
However, it's not uncommon for successful requests to return one type and
errors to return another type. Propagating the plain error allows downstream
error consumers to reason about the error body and decide how to parse it
depending on application needs.

Add support for mode and redirect options in Angular's HttpClient based on fech provider to enable control CORS behavior and redirect handling
PR Close#62315
This commit adds support for the Fetch API's keepalive option when using HttpClient with the withFetch provider.
The change includes:
- Added keepalive to HttpRequestInit interface
- Modified FetchBackend to pass the option
- Added some unit test

Prior to this change, is the `Content-Type` passed to the `FetchBackend` was lowercase it was overwritten with the default one.

The version of rxjs used to build the repository has been updated to v7.
This required only minimal changes to the code. Most of which were type
related only due to more strict types in v7. The behavior in those cases
was left intact. The most common type related change was to handle the
possibility of `undefined` with `toPromise` which was always possible with
v6 but the types did not reflect the runtime behavior. The one change that
was not type related was to provide a parameter value to the `defaultIfEmpty`
operator. It no longer defaults to a value of `null` if no default is provided.
To provide the same behavior the value of `null` is now passed to the operator.

This commit introduces a new `HttpBackend` implentation which makes requests using the fetch API
This feature is a developer preview and is opt-in.
It is enabled by setting the providers with `provideHttpClient(withFetch())`.
NB: The fetch API is experimental on Node but available without flags from Node 18 onwards.
