This commit removes the `Compiler` injectee from the `RouterPreloader` constructor. It's unused but was still being referenced in the factory definition: `static ɵfac = ɵɵngDeclareFactory(...)`.
PR Close#60945
Adds support for asynchronous redirects in the router, allowing redirect logic to be resolved dynamically (e.g., via API or async function). This enhances routing flexibility and supports more complex navigation scenarios.
BREAKING CHANGE: The `RedirectFn` can now return `Observable` or
`Promise`. Any code that directly calls functions returning this type
may need to be adjusted to account for this.
PR Close#60863
Redirects in the router are handled before `canMatch` guards are evaluated. As a result, `canMatch` will not run for routes that include a redirect. Instead of silently ignoring this misconfiguration, developers should be alerted to help them understand why it doesn't behave as expected.

This commit moves zoneless from experimental to developer preview.
* Update tag on provider API
* Remove "experimental" from provider name
* Move documentation from "experimental features" to "Best practives ->
Performance" (at least temporarily until there is a better place)
BREAKING CHANGE: `provideExperimentalZonelessChangeDetection` is
renamed to `provideZonelessChangeDetection` as it is now "Developer
Preview" rather than "Experimental".

Only require a readonly array as input for router commands instead of a writable array. Router itself does not need writable access to the array of commands. If router requires a writable array somebody on the outside would have to spread a readonly array to a new writable array. We can avoid this by just require what route actually needs.
Fixes#60269
BREAKING CHANGE: Several methods in the public API of the Router which
required writable arrays have now been updated to accept readonly
arrays when no mutations are done.

This adjusts code to use `NavigationTrigger` type where appropriate and
moves the `isPublicRouterEvent` next to the private event type union to
make it more obvious that it should be updated along with any updates to
the private type union.

This commit adds the ability to directly abort a navigation through the
`Router.getCurrentNavigation()?.abort()` method. While there are no
feature requests for this, it is a feature that will be necessary for
integration with the navigation API. The API enables better tracking of
an ongoing navigation for SPAs and a site visitor can cancel a
navigation by clicking the stop button in the browser. While this could
technically be done on the transition with an internal jsdoc comment to
hide it from application developers, there's no need.
With this feature, I believe it would be possible to create somewhat of a shim
to integrate with the navigation API even before the router has full support
using the router events to control a deferred navigation that never
commits the URL and always aborts itself on navigation end.

This commit re-exports the symbols that are exposed by the `RouterTestingModule` (which re-exports
the symbols from the `RouterModule`. These re-exports are needed for the Angular compiler
to overcome its limitation (on the consumer side) of not knowing where to import import
symbols when relative imports are used within the package.

This commit updates the `StateManager` base class to contain common
concrete implementations that would be the same regardless of whether
the state manager is backed by the browser history API or the Navigation
API.

This commit updates the OutletInjector and related code to avoid special handling of that injector. The main code that had special handling was refactored to no longer require is in https://github.com/angular/angular/pull/56763, this commit completes the cleanup.

This commit removes `'any'` from the type union for router guards and
replaces it with 'string', which will eventually also be removed. This
change allows TypeScript to infer the parameter types of functions when
using functional guards and enables stricter type-checking to ensure the
guard array contains valid values.
BREAKING CHANGE: The guards arrays on `Route` no longer include `any` in
the type union. The union includes functions for the functional guards
as well as a type matching `Injector.get`: `ProviderToken<T>|string`.
Note that string is still deprecated on both the route guards and
`Injector.get`.

Node.js v18 will reach End-of-Life on April 30, 2025, and will no longer be supported in Angular v20.
Node.js Release Schedule: https://github.com/nodejs/release#release-schedule
BREAKING CHANGE:
- Angular no longer supports Node.js v18.
- Node.js versions 22.0 to 22.10 are also no longer supported.
Before upgrading to Angular v20, ensure the Node.js version is at least 20.11.1.

`TestBed.get` isn't type safe and has been deprecated for several years now. These changes remove it from the public API and a follow-up change will add an automated migration to `TestBed.inject`.

This commit cleans up the transition subject a bit so it doesn't use a dummy
initial value. It also avoids copying over data from the previous
request when a new one is created.
PR Close#60357
Removes the deprecated `InjectFlags` symbol from the `@angular/core` public API, as well as all the places that accept it. The previous commit includes an automated migration to switch over to the new way of passing in flags.
BREAKING CHANGE:
* `InjectFlags` has been removed.
* `inject` no longer accepts `InjectFlags`.
* `Injector.get` no longer accepts `InjectFlags`.
* `EnvironmentInjector.get` no longer accepts `InjectFlags`.
* `TestBed.get` no longer accepts `InjectFlags`.
* `TestBed.inject` no longer accepts `InjectFlags`.

Though the plan is to change the default behavior or the router to
instead resolve the navigation promise with `false` to match all other
failed navigations, we should still prevent dangling promise rejections
from navigations triggered internally when developers opt to use the old
(current) behavior.

Using `setTimeout` to delay scrolling can result in scrolling in the
next frame and cause noticeable flicker. This commit races rAF and
timeout to ensure scroll happens before the render.

This commit updates the resolver execution to ensure that resolvers in
children routes are able to read the resolved data from anything above
them in the route tree. Because resolvers on one level block execution
of those below, it seems more of an oversight in the initial
implementation than anything else that this wasn't already possible.

In this commit, we prevent error handling when the root injector is already destroyed. This may happen when the observable completes before emitting a value, which would trigger a `catchError` block that attempts to call `runInInjectionContext` on a destroyed injector.

In this commit, we switch from decorators (which also produce redundant metadata, such as in the `declareFactory`
instruction) to the `inject` function to drop the `ROUTER_FORROOT_GUARD` token in production. This token factory function is only in development mode but is still referenced in the constructor due to the `@Inject(ROUTER_FORROOT_GUARD)` decorator.

Prior to this commit, the compiler produced:
```js
No = (function (e) {
return (
(e[(e.None = 0)] = "None"),
(e[(e.HasTransplantedViews = 2)] = "HasTransplantedViews"),
e
);
})(No || {});
```
Changing to `const enum` allows it to be entirely dropped and inline values.

In this commit, we manually complete the `events` subject to remove all active observers and enable
granular garbage collection, as users may forget to unsubscribe manually when subscribing to `router.events`.
PR Close#59327
Currently the `ɵEmptyOutletComponent` is very prone to generating ID collision warnings with user code, because it only has one child and no other metadata. This shows up some of our tests as well. While users can resolve it on their end, it can be confusing since they won't have any references to `ɵEmptyOutletComponent` in their own code.
These changes add an `exportAs` to it to make its component ID unique. This doesn't affect the public API of the component since users can't use it directly anyways.
