The NgOptimizedImage directive was previously trying to use an
already destroyed injector in the ngOnDestroy callback. This fix
pre-injects necessery tokens so no injector calls are done
in the destroy process.

Valid density descriptors used in the NgOptimizedImage can contain multiple
digits (ex. 1.25x, 25x). This change fixes the issue where density descriptors
with multiple digits (ex. 25x) where considered invalid.
Please note that a valid density descriptor might still be rejected by the
directive's validation logic if the supplied value is too big.
PR Close#47230
This commit fixes a bug where `rawSrcset` in the image
directive would allow density descriptors like `1.5x`
but not like `1.25x`. Now descriptors with 2+ digits
after the decimal point should work.

This is a tiny commit to add newlines in the image
directive's "oversized image" error. Currently, the
rendered and intrinsic image sizes are printed
mid-line, which make them a little hard to read.
This commit puts them each on their own line.

This helper accepts a class for an Angular trait, and returns the NgModule which owns that trait. This will be useful for the language service import project, which needs to edit import arrays on the module.

prior to this change the stagger timing was being built during the
ast building instead of dynamically when visiting the stagger animation,
thus it could not handle params correctly, this change makes it so that
during ast building a timing ast is built instead and that ast is used
dynammically to build animations which can handle params correctly

Create three new helper methods: `addElementToArrayLiteral`, `objectPropertyAssignmentForKey`, and `updateObjectValueForKey`. These methods make interacting with array and object literals easier.
These will be useful for the standalone imports feature, which will need to add new terms to import arrays in Component and NgModule decorators.

This helper accepts a class, and returns the primary Angular Decorator associated with that trait (e.g. the Component, Pipe, Directive, or NgModule decorator). This will be useful for the language service import project, which needs to edit import arrays inside the decorator.

Fix compilation issue with TypeScript nightly. TypeScript added a field
`0` to `RegExpMatchArray` in
https://github.com/microsoft/TypeScript/commit/3b80ddca212959ae5dcf2f48704be627283c6468.
Before that, `RegExpMatchArray` and `RegExpExecArray` were identical.
In one place Angular incorrectly expects `RegExpMatchArray` as the
result of a RegExp#exec() call. This assignment fails on TypeScript
nightly with the error:
Property '0' is missing in type 'RegExpExecArray' but required in type 'RegExpMatchArray'.
Fix the issue by using the type `RegExpExecArray` instead. This also
works for older TypeScript versions.

Type inference in cases involving `ControlConfig` was previously not working as desired. This was because the compiler was enforcing that `ControlConfig` is a *tuple* -- which is not always that easy to prove! By relaxing this constraint a bit, and just inferring from `ControlConfig` as an array, the type inference catches many more cases, and is generally more correct.
PR Close#47034
In #39004 some logic was introduced that tries to recover invalid expressions by treating the `=` token as a recovery point. It works by skipping ahead to the next recovery point inside the `skip` method which is called whenever an error is reported. This can lead to an infinite loop inside the `parseChain` method which assumes that reporting an error would've skipped over the token, but that won't happen since the `=` token is a recovery point. These changes resolve the infinite loop by breaking the loop if `error` didn't skip to a different token after the error was reported.
Fixes#47131.

This commit adds a console warning in development mode
if the ultimate rendered size of the image is much
smaller than the dimensions of the requested image.
In this case, the warning recommends adjusting the
size of the source image or using the `rawSrcset`
attribute to implement responsive sizing.

This commit cleans up some stylistic nits and

This commit fixes a bug in NgOptimizedImage where
if you bound the width or height attribute (e.g.
`[width]=width`), the attribute would only be
reflected as "ng-reflect-x". The actual "width" or
"height" attribute would not be set on the host
element. This is a problem because the exact named
attribute must be set on the element for the
browser to detect it and use it to reserve space
for the image (and thus prevent CLS).

This commit adds the docs for the NgOptimizedImage directive.
As a part of this commit, we also remove an export of directive-related symbols previously exposed as public APIs (i.e. APIs can not be used directly).

With this commit, the NgOptimizedImage directive will throw
a runtime error if it detects that one of the density descriptors
in rawSrcset is higher than 3x. It's generally not recommended
to use density descriptors higher than ~2, as it causes image to
download at very large sizes on mobile screens (thus slowing down
LCP). The density max is set conservatively to 3 in case apps
expect users to zoom in.
In future commits, we may want to throw even at densities >
than 2 and provide a configuration override for the zoom case.

This commit updates the logic of Image Loaders to throw an error in case an absolute URL is provided an an input to the loader function. The loaders can construct URLs based on image paths relative to the bas URL configured for a loader.

Refactoring tests made me realise that we are misinterpreting the

This change introduces common infrastructure for image
loaders. This removes code duplication and makes it
easier to write loaders - a loader author just needs
to provide a loader config to the URL mapping function.

This commit updates the image loader tests to avoid creating the TestBed environment, since it's not really needed for the tests. Instead, the loader functions are invoked directly and the output is verified.

This commit modifies the provideImgixLoader function to support

As more loaders get developed we will refactor code to streamline
