When a component/directive has a generic type parameter, the template
type checker attempts to translate the type parameter such that the
type parameters can be replicated in the type constructor that is
emitted into the typecheck file.
Type parameters with a default clause would incorrectly be emitted into
the typecheck file using the original `ts.TypeNode` for the default
clause, such that `ts.TypeReferenceNode`s within the default clause
would likely be invalid (i.e. referencing a type for which no import is
present in the typecheck file). This did not result in user-facing
type-check errors as errors reported in type constructors are not
translated into template positions Regardless, this commit ensures that
`ts.TypeReferenceNode`s within defaults are properly translated into the
typecheck file.

The template type checker is capable of recreating generic type bounds
in a different context, rewriting type references along the way (if
possible). This was previously done using a visitor that only supported
a limited set of types, resulting in the inability to emit all sorts of
types (even if they don't contain type references at all).
The inability to emit generic type bounds was not critical when the type
parameter emitting logic was introduced, as the compiler also has a
fallback strategy of creating inline type constructors. However, this
fallback is not available to the language service, resulting in
inaccurate types when components/directives use a complex generic type.
To mitigate this problem, the specialized visitor has been replaced with
a generalized TypeScript transform, where only type references get
special treatment. This allows for more complex types to be emitted,
such as union and intersection types, object literal types and tuple
types.

If an implcit receiver is accessed in a listener inside of an `ng-template`, we generate some extra code in order to ensure that we're assigning to the correct object. The problem is that the logic wasn't covering keyed writes which caused it to write to the wrong object and throw an assertion error at runtime.
These changes expand the logic to cover keyed writes.
Fixes#41267.

Previously, redirects had to be configured in both the Firebase config
(`firebase.json`) and the ServiceWorker config (`ngsw-config.json`).
This made it challenging to correctly configure redirects, since one had
to understand the different formats of the two configs, and was also
prone to getting out-of-sync configs.
This commit simplifies the process of adding redirects by removing the
need to update the ServiceWorker config (`ngsw-config.json`) and keep it
in sync with the Firebase config (`firebase.json`). Instead the
ServiceWorker `navigationUrls` are automatically generated from the list
of redirects in the Firebase config.
NOTE:
Currently, the automatic generation only supports the limited set of
patterns that are necessary to translate the existing redirects. It can
be made more sophisticated in the future, should the need arise.
PR Close#42452
The ServiceWorker `navigationUrls` globs defined in `ngsw-config.json`
are supposed to exclude any URLs that are redirected on the server (as
configured in `firebase.json`). However, the list of redirected
URLs/globs in `firebase.json` and `ngsw-config.json` have gotten out of
sync.
This commit updates the globs in `ngsw-config.json` to match the ones in
`firebase.json`.

Previously, we were not consistent in allowing a trailing `/` in
`navigationUrls` globs in `ngsw-config.json`. And when we did, we used

trailing `/`. It also merges the two glob patterns (the one with and the
one without the `/`) into one.

This commit removes some `navigationUrls` globs from `ngsw-config.json`
that have no effect. More specifically:
- It removes globs of the form `!/**/xyz.html`, since these are already
covered by the more generic `!/**/*.*` glob.
- It removes `!/api/**/NgFor`, since it does not have a corresponding
redirect rule in `firebase.json`.

This commit adds a test assertion to verify that all redirect rules

tested.

Previously, the `destinations` test suite in

inside) the `with legacy URLs` one.

Previously, the `NotificationComponent` would be hidden by reducing its
height to `0`. This allowed for a smoother hide animation when closing
the notification, but left the component's interactive elements
focusable via keyboard navigation. This was confusing for users, because
the focused elements would not be visible on the page.
This commit fixes the issue be also setting the `display` CSS property
to `none` when the `NotificationComponent` is hidden, thus ensuring that
its contents are not focusable via keyboard navigation.
(This does not affect the hide animation, since the `display` style is
not animatable and is only applied at the end of the animation.)

Previously, we included a dummy `MatIcon` element in `AppComponent` in
order to ensure that the `Material Icons` font would be requested (and
thus cached by the ServiceWorker) on every navigation. However, #41129
introduced the `ThemeToggleComponent`, which will be present on all
pages (since it is located in the top-menu) and relies on the
`Material Icons` font. Therefore, the work-around for loading the
`Material Icons` font is no longer necessary.
This commit removes the now redundant `MatIcon` from `AppComponent`.

This commit changes the anchor elements used for external links to
`MatIconButton`s. While the appearance remains the same (with the
exception of hover/focus styles), this better aligns the styling of
external link icons with other nearby icon buttons (i.e. the theme
toggle) and alows as to simplify the CSS for external links (since much
of their styling is handled by Angular Material).
PR Close#42584
Since we now use SVG for external link icons, there are no `<img>`
elements inside the anchor elements. So, the CSS rule does not match any

Previously, we only tracked the sizes of the eagerly loaded JS bundles.
However, the CSS styles (which also have a non-negligible size) must

This is something I ran into while working on a fix for the `TestBed` module teardown behavior for #18831. In the `RouterInitializer.appInitializer` we have a callback to the `LOCATION_INITIALIZED` which has to do some DI lookups. The problem is that if the module is destroyed before the location promise resolves, the `Injector.get` calls will fail. This is unlikely to happen in a real app, but it'll show up in unit tests once the test module teardown behavior is fixed.
PR Close#42560
We currently have two long-standing issues related to how `TestBed` tests are torn down:
1. The dynamically-created test module isn't going to be destroyed, preventing the `ngOnDestroy` hooks on providers from running and keeping the component `style` nodes in the DOM.
2. The test root elements aren't going to be removed from the DOM. Instead, they will be removed whenever another test component is created.
By themselves, these issues are easy to resolve, but given how long they've been around, there are a lot of unit tests out there that depend on the broken behavior.
These changes address the issues by introducing APIs that allow users to opt into the correct test teardown behavior either at the application level via `TestBed.initTestEnvironment` or the test suite level via `TestBed.configureTestingModule`.
At the moment, the new teardown behavior is opt-in, but the idea is that we'll eventually make it opt-out before removing the configuration altogether.
Fixes#18831.
