The ExperimentalPendingTasks service was accidently exposing one of its
internal fields as a public one. This commit fixes this by marking the
field in question as private.
PR Close#55516
The new ExperimentalPendingTasks API lets developers to add and remove
tasks that control applications stability: a pending task prevents
application from being stable.
This API is important for all the use-cases that depend on the concept
of stability and SSR serialization is a notable example.

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.

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.

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.

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.

This commit ensures components in the route config predictably always

sometimes being dependent on where they are inserted.
fixes#53369
BREAKING CHANGE: Providers available to the routed components always
come from the injector heirarchy of the routes and never inherit from
the `RouterOutlet`. This means that providers available only to the
component that defines the `RouterOutlet` will no longer be available to

whenever routes defined providers, either through lazy loading an
`NgModule` or through explicit `providers` on the route config.

This commit updates the internal resolve value of the navigation promise
to use `false` instead of `null` when a navigation is skipped. The

`false` instead.

This change aligns the stability of `ComponentFixture` with that of
`ApplicationRef`, preventing confusing differences between the two as
more APIs start using the `PendingTasks` that may not be tracked by
`NgZone`.
BREAKING CHANGE: `ComponentFixture.whenStable` now matches the
`ApplicationRef.isStable` observable. Prior to this change, stability
of the fixture did not include everything that was considered in
`ApplicationRef`. `whenStable` of the fixture will now include unfinished
router navigations and unfinished `HttpClient` requests. This will cause
tests that `await` the `whenStable` promise to time out when there are
incomplete requests. To fix this, remove the `whenStable`,
instead wait for another condition, or ensure `HttpTestingController`
mocks responses for all requests. Try adding `HttpTestingController.verify()`
before your `await fixture.whenStable` to identify the open requests.
Also, make sure your tests wait for the stability promise. We found many
examples of tests that did not, meaning the expectations did not execute
within the test body.
In addition, `ComponentFixture.isStable` would synchronously switch to
true in some scenarios but will now always be asynchronous.

An initializer API like `input`, `output`, or signal queries may not be
compatible with certain access levels. E.g. queries cannot work with ES
private class fields.
This commit introduces a check for access levels into the initializer
API recognition— enforcing that every initializer API *clearly*
specifies what type of access is allowed.

This commit improves the API documentation for `input` after
we added support for initializer APIs in angular.dev docs generation.
Changes:
- Rename `ReadT` to `T`. This conceptually makes it easy to talk about
inputs of type `T` if there is no transform involved. The common case.
- Rename `WriteT` to `TransformT`. This makes it clear that this is the
type that the "transform" needs to handle.
- Improves the "overall" description of the input function so that it
can be shown as a general overview for the API site.
- Improves usage notes to be a little more helpful, yielding more useful
content in the API docs usage notes section.
- Add short JSDoc description for each individual overload.

This commit updates the logic around `Route.redirectTo` to enable using a
function to create the redirect. This function can return a string,
ands acts the same as previous string redirects, or a `UrlTree`, which
will act as an absolute redirect.
To be useful, the redirect function needs access to the params and data.
Today, developers can access these in their redirect strings, for
example `{path: ':id', redirectTo: '/user/:id'}`. Unfortunately,
developers only have access to params and data on the _current route_
today in the redirect strings. The params and data in the `RedirectFn`
give developers access to anything from the matched parent routes as
well. This is done as the same way as param and data aggregation later
on (https://github.com/angular/angular/blob/897f014785578d87bc655ea6ae9e113653960f50/packages/router/src/router_state.ts#L236-L278).
In order to accomplish this, we inherit params and data while
matching, after the `ActivatedRouteSnapshot` is created for the matched
route rather than waiting until the end.
The `RedirectFunction` does not return the full
`ActivatedRouteSnapshot` interface. Some things are not accurately known
at the route matching phase. For example, resolvers are not run until
later, so any resolved title would not be populated. The same goes for lazy
loaded components. The is also true for all the snapshots up to the
root, so properties that include parents (root, parent, pathFromRoot)
are also excluded. And naturally, the full route matching hasn't yet
happened so firstChild and children are not available either.
fixes#13373resolves#28661 (though not for the redirect string - you would return a
`UrlTree` from the function)
BREAKING CHANGE: This change allows `Route.redirectTo` to be a function
in addition to the previous string. Code which expects `redirectTo` to
only be a string on `Route` objects will need to be adjusted.

Returning `UrlTree` from a guard was a convenient new feature added to
the `Router`. However, it does not have feature-parity with the old
`router.navigate(...); return false;` pattern. The most common use-case
for this feature is to redirect to a new page _without_ updating the URL
from the initially attempted navigation. For example, rendering a 404
page when the user does not have access privelages to a route.

An `EventEmitter` is a construct owned by Angular that should be
used for outputs as of right now.
As we are introducing the new `OutputRef` interface for the new output
function APIs, we also think `EventEmitter` should implement
`OutputRef`— ensuring all "known" outputs follow the same contract.
This commit ensures `EventEmitter` implements an `OutputRef`
Note: An output ref captures the destroy ref from the current injection
context for clean-up purposes. This is also done for `EventEmitter` in a
backwards compatible way:
- not requiring an injection context. EventEmitter may be used
elsewhere.
- not cleaning up subscriptions/completing the emitter when the
directive/component is destroyed. This would be a change in behavior.
Note 2: The dependency on `DestroyRef` causes it to be retained in all
bundling examples because ironically `NgZone` uses `EventEmitter`- not
for outputs. The code is pretty minimal though, so that should be
acceptable.
`EventEmitter` will now always retain `NgZone. This increases the
payload size slightly around 800b for AIO. Note that the other increases
were coming from previous changes. This commit just pushed it over the
threshold.
