This migration will allow developers to migrate the deprecated `HttpClientModule`, `HttpClientJsonpModule` & `HttpClientXsrfModule` to their respective provider functions.
PR Close#54020
This commit deprecates the `HttpClientModule` and other related http modules. Those can be replaced by provider function only.
Angular is an opinionated framework, feature guidance will help developer choose the recommended way to enable feature (like Http requests here).
Note: This is not an indication of deprecation for `NgModule`. The deprecated module's only purpose here was to define providers. This can be done directly by the provide function pattern.
DEPRECATED: `HttpClientModule`, `HttpClientXsrfModule` and `HttpClientJsonpModule`
As mentionned, those modules can be replaced by provider function only.

The change in the index is to allow the framework to add a type to the object that is passed from the contract to the dispatcher. ie
registerDispatcher(contract, (eventInfo: EventInfoWrapper) => ...).
The latter is to return the event contract so that tests can clean it up.

`RouterOutlet` uses a unique injector logic that returns a value that correspond to the `ActivatedRoute` token dynamically. This logic breaks when a component/directive/pipe that injects the `ActivatedRoute` is located within a `@defer` block, because defer creates an `EnvironmentInjector` instance, which doesn't have that dynamic logic.
We've added some special handling of the `OutletInjector` in one of the previous commits, but it was incomplete and it was not covering cases when different routes use the same component. This commit updates defer logic to re-establish this dynamic behavior for `ActivatedRoute` by creating an instance of the `OutletInjector` when a parent injector was also an instance of `OutletInjector`.
This fix is a short-term solution and longer term we should find a way to achieve the dynamic behavior that Router relies on, but without adding a special case logic into defer.

PR #51670 removed the usage of `const enum`. As a consequence HttpStatusCode that were previously inlined now pull and retains the (fairly large) `HttpStatusCode` enum.
By intermediate constants, we prevent the framework from pulling this big enum by default.

Angular DevTools depends on many modern Angular features in order to function. As a result, at present the last officially supported version is v12. Angular DevTools may function for some Angular 9, 10 and 11 applications, but they are not officially supported.
This commit fixes an issue where DevTools would not inject a backend script into an Angular application if it detected it was below version 12. This backend script is important because it's used to inform the DevTools panel that the inspected application is in fact Angular, but that it is not on a supported version.
Angular 9, 10 and 11 applications that successfully have Angular DevTools initialize will now have a red highlight and tooltip on their version number, informing the user that they are using Angular DevTools on a version of Angular that is no longer supported.
Angular DevTools for applications that are below version 9 will continue to display the "Angular Devtools supports Angular versions 12 and above" message.

This commit introduces a check plus an associated warning for situations where
the combination of the collection change and the tracking expression resulted
in the entire view structure managed by @for to be re-created.
The check uses the following conditions before raising a warning:
- the entire collection was re-created and there were no other operations (ex.: move);
- views in a collection are considered "expensive" to re-create;
- a developer is using tracking by identity.
The last condition tries to capture cases where changes to immutable data
collections can cause significent performance and / or corectness problems.
Note that this warning might be "overreacting" and report cases where
the collection re-creation is the intended behavior. Still, the assumption is that
most of the time it is undesired.

Angular only checks the contents of template nodes in full type checking mode. After v17, the new control flow always had its body checked, even in basic mode, which started revealing compilation errors for apps that were using the schematic to automatically switch to the new syntax.
These changes mimic the old behavior by not checking the bodies of `if`, `switch` and `for` blocks in basic mode. Note that the expressions of the blocks are still going to be checked.
Fixes#52969.

This commit adds helpful stack information for the case when change
detection continues to be triggered in the event loop and would cause
the browser to freeze.
PR Close#55231
There is an existing pattern that zone-based applications use to avoid
`ExpressionChangedAfterItHasBeenCheckedError` which is also used in
`NgModel`: update the state in a microtask instead of doing it
synchronously. This defers the state update to another round of change
detection, and with ZoneJS, also still executes in the same event loop.
These types of changes across multiple rounds of change detection were
still executed before the browser paint.
This update allows the `NgModel` workaround to continue working in
Zoneless. This may not be permanent and is certainly still not
advisable. Render hooks (`afterNextRender`/`afterRender`) will execute between these
rounds of change detection when they are intended to be run after all
DOM updates completed.

This commit adds the ability to return `RedirectCommand` from the error
handler provided by `withNavigationErrorHandler`. This will prevent the
error from being surfaced in the `events` observable of the Router and
instead convert the error to a redirect. This allows developers to
have more control over how the Router handles navigation errors. There
are some cases when the application _does not_ want the URL to be reset
when an error occurs.

This commit ensures we correctly handle the exit from the zone.run in
the zoneless scheduler. Run coalescing would delay the `onMicrotaskEmpty` event
until after we have exited the change detection triggered by the
zoneless scheduler and mean that the subscription cannot determine if
`ApplicationRef.tick` should be skipped.

For ideal DOM usage, you would not unwrap an ElementRef outside of the browser. However, it's reasonable to want to find the tag name of the host node on the server, and so this introduces a HOST_TAG_NAME token that can be injected to read this value.

Flip `stopPropagation` constructor parameter default to `false` for
`EventContract` and `EventContractMultiContainer`. Change type for
`EventContract` to `false` to indicate that no values besides `false`
should be passed. This enables removing all usages of `stopPropagation`
in `EventContract` and leaving only usages of `stopPropagation = true`
for `EventContractMultiContainer`.

When `cleanUp` is called `containerManager` is set to null. Currently
the `EventContract` API assumes that users know not to call further
methods on `EventContract`, but this lead to a bug in a downstream app,

not null.

This commit integrates the JSA contract binary into the NPM package and ensures its accessibility by including it in the package exports. This adjustment is essential for enabling Angular CLI to effectively access and inject the script.

This commit loosens the restrictions on calling `ComponentFixture.detectChanges`
when using the zoneless scheduler. While we don't necessarily think it's
a good idea, the thought is that it's unnecessary mental overhead to
diverge behaviors in the API when zoneless is enabled versus when it is
not. Instead, these opinionated restrictions can be considered when we
look at new testing APIs.
