Now, hovering over an attribute on an element will provide information
about the directive that attribute matches in the element, if any.
(More generally, we return information about directive symbols
matched on an element attribute.)
I believe this is similar to how the indexer provides this kind of
information, though more precise in the sense that this commit provides
directive information only if the directive selector exactly matches the
attribute selector. In another sense, this is a limitation.
In fact, there are the limitations of:
- Directives matched on the element, but with a selector of anything
more than the attribute (e.g. `div[string-model]` or
`[string-model][other-attr]`) will not be returned as symbols matching
on the attribute.
- Only one symbol can be returned currently. If the attribute matches
multiple directives, only one directive symbol will be returned.
Furthermore, we cannot say that the directive symbol returned is
determinstic.
Resolution of these limitations can be discussed in the future. At least
the second limitation should be very easy to fixup in a future commit.
This relies solely on the template compiler and is agnostic to any Ivy
changes, so this is strictly a feature enhancement that will not have to
be refactored when we migrate the language service to Ivy.

Prior to this change, a static attribute that corresponds with a
directive's input would not be type-checked against the type of the
input. This is unfortunate, as a static value always has type `string`,
whereas the directive's input type might be something different. This
typically occurs when a developer forgets to enclose the attribute name
in brackets to make it a property binding.
This commit lets static attributes be considered as bindings with string
values, so that they will be properly type-checked.

This commit introduces an internal config option of the template type
checker that allows to disable strict null checks of input bindings to
directives. This may be particularly useful when a directive is from a
library that is not compiled with `strictNullChecks` enabled.
Right now, strict null checks are enabled when `fullTemplateTypeCheck`
is turned on, and disabled when it's off. In the near future, several of
the internal configuration options will be added as public Angular
compiler options so that users can have fine-grained control over which
areas of the template type checker to enable, allowing for a more
incremental migration strategy.
PR Close#33066
Prior to this change, the template type checker would always allow a
value of type `undefined` to be passed into a directive's inputs, even
if the input's type did not allow for it. This was due to how the type
constructor for a directive was generated, where a `Partial` mapped
type was used to allow for inputs to be unset. This essentially
introduces the `undefined` type as acceptable type for all inputs.
This commit removes the `Partial` type from the type constructor, which
means that we can no longer omit any properties that were unset.
Instead, any properties that are not set will still be included in the
type constructor call, having their value assigned to `any`.
Before:
```typescript
class NgForOf<T> {
static ngTypeCtor<T>(init: Partial<Pick<NgForOf<T>,
'ngForOf'|'ngForTrackBy'|'ngForTemplate'>>): NgForOf<T>;
}
NgForOf.ngTypeCtor(init: {ngForOf: ['foo', 'bar']});

```typescript
class NgForOf<T> {
static ngTypeCtor<T>(init: Pick<NgForOf<T>,

ngForOf: ['foo', 'bar'],
ngForTrackBy: null as any,

Prior to this fix, whenever a style or class binding is present, the

This check is, however, unnecessary because if (and only if) there
are directives present on the element then are collisions possible.
This patch removes the need for style/class bindings to register

present on an element. This means that all map and prop-based

Currently the `ngForOf` input accepts `null` or `undefined` as valid
values. Although when using strict template input type checking
(which will be supported by `ngtsc`), passing `null` or `undefined`
with strict null checks enabled causes a type check failure because
the type for the `ngForOf` input becomes too strict if strict null checks
are enabled. The type of the input needs to be expanded to also accept
`null` or `undefined` to behave consistently regardless of the
`strictNullChecks` flag.
This is necessary because whenever strict input type checking is enabled
by default, most of the Angular projects that use `*ngFor` with the async pipe
will either need to disable template type checking or strict null checks
because the `async` pipe returns `null` if the observable hasn't been
emitted yet.
See for example how this affects the `angular/components` repository and
how much bloat the workaround involves: https://github.com/angular/components/pull/16373/files#r296942696.

In View Engine, animation metadata could occur in nested arrays which
would be flattened in the compiler. When compiling a component for Ivy
however, the compiler no longer statically evaluates a component's
animation metadata and is therefore unable to flatten it statically.
This resulted in an issue to find animations at runtime, as the metadata
was incorrectly registered with the animation engine.
Although it would be possible to statically evaluate the animation
metadata in ngtsc, doing so would prevent reusable animations exported
from libraries from being usable as ngtsc's partial evaluator is unable
to read values inside libraries. This is unlike ngc's usage of static
symbols represented in a library's `.metadata.json`, which explains how
the View Engine compiler is able to flatten the animation metadata
statically.
As an alternative solution, the metadata flattening is now done in the
runtime during the registration of the animation metadata with the
animation engine.

- Mark all groups as non-capturing (since we do not use the captured

Currently the undecorated-classes-with-di migration leverages NGC in order
to work with metadata resolution. Since NGC by default tries to resolve referenced
resources on initialization of the underlying TS program, it can result in unexpected

This is especially an issue since the CLI wraps the `AngularCompilerProgram` with
special logic (i.e. to support SCSS preprocessing etc.). We don't have all of this since
we instantiate a vanilla NGC program.

ivy when creating the `@angular/compiler-cli` program for the migration.
This code is still relevant even though the update from version 7
to version 8 landed. Developers can run `ng update` from version 7
and immediately get to version 9 where Ivy is enabled by default (and in
that case we need to ensure that ngtsc is not accidentally used).

In an attempt to be compatible with previous translation files
the Angular compiler was generating instructions that always
included the message id. This was because it was not possible
to accurately re-generate the id from the calls to `$localize()` alone.
In line with https://hackmd.io/EQF4_-atSXK4XWg8eAha2g this
commit changes the compiler so that it only renders ids if they are
"custom" ones provided by the template author.
NOTE:
When translating messages generated by the Angular compiler
from i18n tags in templates, the `$localize.translate()` function
will compute message ids, if no custom id is provided, using a
common digest function that only relies upon the information
available in the `$localize()` calls.
This computed message id will not be the same as the message
ids stored in legacy translation files. Such files will need to be
migrated to use the new common digest function.
This only affects developers who have been trialling `$localize`, have
been calling `loadTranslations()`, and are not exclusively using custom
ids in their templates.

Similarly to `ts_library` compilation actions, the `ng_module` compile action should include
the current compile mode in the action description. This makes it consistent with `ts_library`
targets and also avoids confusion when both output flavors are requested.
Currently when both output flavors are requested (e.g. in the `ng_package` rule), both
devmode and prodmode compilations have the same action name. This is confusing and
looks like the given target is built *twice* due to a bug (which is obviously not the case though)

With #31953 we moved the factories for components, directives and pipes into a new field called `ngFactoryDef`, however I decided not to do it for injectables, because they needed some extra logic. These changes set up the `ngFactoryDef` for injectables as well.
For reference, the extra logic mentioned above is that for injectables we have two code paths:
1. For injectables that don't configure how they should be instantiated, we create a `factory` that proxies to `ngFactoryDef`:
```
// Source
@Injectable()
class Service {}
// Output
class Service {
static ngInjectableDef = defineInjectable({
factory: () => Service.ngFactoryFn(),
});
static ngFactoryFn: (t) => new (t || Service)();
}
```
2. For injectables that do configure how they're created, we keep the `ngFactoryDef` and generate the factory based on the metadata:
```
// Source
@Injectable({
useValue: DEFAULT_IMPL,
})
class Service {}
// Output
export class Service {
static ngInjectableDef = defineInjectable({
factory: () => DEFAULT_IMPL,
});
static ngFactoryFn: (t) => new (t || Service)();
}

There are a couple scenarios that are problematic and need special
handling:
1. A user has a custom implementation of lazy-loaded modules, sets some
provider overrides, then compiles the module so it can be loaded. In a
follow-up test, the user sets different overrides for the module and
then compiles. This is problematic because we need to be sure the module
registered in the first test is not used, so we need to clear it out of
the modules list in `ng_module_factory_registration`.
2. A user has a similar lazy-loaded module factory implementation but
relies on the module being registered automatically. This can happen,
for example, as a side effect of importing the ngfactory file.

Recently ng-packagr was updated to include a transform that used to be
done in tsickle (https://github.com/ng-packagr/ng-packagr/pull/1401),
where only constructor parameter decorators are emitted in tsickle's
format, not any of the other decorators.
ngcc used to extract decorators from only a single format, so once it
saw the `ctorParameters` static property it assumed the library is using
the tsickle format. Therefore, none of the `__decorate` calls were
considered. This resulted in missing decorator information, preventing
proper processing of a package.
This commit changes how decorators are extracted by always looking at
both the static properties and the `__decorate` calls, merging these
sources appropriately.

ngcc may need to insert public exports into the bundle's source as well
as to the entry-point's declaration file, as the Ivy compiler may need
to create import statements to internal library types. The way ngcc
knows which exports to add is through the references registry, to which
references to things that require a public export are added by the
various analysis steps that are executed.
One of these analysis steps is the augmentation of declaration files
where functions that return `ModuleWithProviders` are updated so that a
generic type argument is added that corresponds with the `NgModule` that
is actually imported. This type has to be publicly exported, so the
analyzer step has to add the module type to the references registry.
A problem occurs when `ModuleWithProviders` already has a generic type
argument, in which case no update of the declaration file is necessary.
This may happen when 1) ngcc is processing additional bundle formats, so
that the declaration file has already been updated while processing the
first bundle format, or 2) when a package is processed which already
contains the generic type in its source. In both scenarios it may occur
that the referenced `NgModule` type does not yet have a public export,
so it is crucial that a reference to the type is added to the
references registry, which ngcc failed to do.
This commit fixes the issue by always adding the referenced `NgModule`
type to the references registry, so that a public export will always be
created if necessary.

properties were read twice, making the `setStyle` \ `setClass` functions the

Now that the `$localize` translations are `MessageId` based the
compiler must render `MessageId`s in its generated `$localize` code.
This is because the `MessageId` used by the compiler is computed
from information that does not get passed through to the `$localize`
tagged string.
For example, the generated code for the following template
```html
<div id="static" i18n-title="m|d" title="introduction"></div>
```
will contain these localization statements
```ts
if (ngI18nClosureMode) {
/**
* @desc d
* @meaning m
*/
const MSG_EXTERNAL_8809028065680254561$$APP_SPEC_TS_1 = goog.getMsg("introduction");
I18N_1 = MSG_EXTERNAL_8809028065680254561$$APP_SPEC_TS_1;
}
else {
I18N_1 = $localize \`:m|d@@8809028065680254561:introduction\`;
}
```
Since `$localize` is not able to accurately regenerate the source-message
(and so the `MessageId`) from the generated code, it must rely upon the
`MessageId` being provided explicitly in the generated code.
The compiler now prepends all localized messages with a "metadata block"
containing the id (and the meaning and description if defined).
Note that this metadata block will also allow translation file extraction
from the compiled code - rather than relying on the legacy ViewEngine
extraction code. (This will be implemented post-v9).
Although these metadata blocks add to the initial code size, compile-time
inlining will completely remove these strings and so will not impact on
production bundle size.

Within an Angular package, it can happen that there are
entry-points which do not contain features that belong into
an `@NgModule` or need metadata files to be generated.
For example: the `cdk`, `cdk/testing` and `cdk/coercion`
entry-points. Besides other entry-points in the `cdk`
package, those entry-points do not need metadata to
be generated and no not use the `ng_module` rule.
Currently the "ng_package" rule properly picks up such
entry-points and builds bundles, does downleveling etc.
The only thing it misses is that no `package.json` files
are generated for the entry-point. This means that consumers
will not be able to use these entry-points built with "ts_library"
(except accessing the individual bundlings explicitly).
The "ng_package" rule should follow the full APF specification
for such entry-points. Partially building bundles and doing the
downleveling is confusing and a breaking issue.
The motifivation of supporting this (besides making the
rule behavior consistent; the incomplete output is not
acceptable), is that using the "ng_module" rule does
not make sense to be used for non-Angular entry-points.
Especially since it depends on Angular packages to
be specified as Bazel action inputs just to compile
vanilla TypeScript with `@angular/compiler-cli`.

This is a refactoring that moves the source code around to provide a better
platform for adding the compile-time inlining.
1. Move the global side-effect import from the primary entry-point to a
secondary entry-point @angular/localize/init.
This has two benefits: first it allows the top level entry-point to
contain tree-shakable shareable code; second it gives the side-effect
import more of an "action" oriented name, which indicates that importing
it does something tangible
2. Move all the source code into the top src folder, and import the localize
related functions into the localize/init/index.ts entry-point.
This allows the different parts of the package to share code without
a proliferation of secondary entry-points (i.e. localize/utils).
3. Avoid publicly exporting any utilities at this time - the only public
API at this point are the global `$localize` function and the two runtime
helpers `loadTranslations()` and `clearTranslations()`.
This does not mean that we will not expose additional helpers for 3rd
party tooling in the future, but it avoid us preemptively exposing
something that we might want to change in the near future.
Notes:
It is not possible to have the `$localize` code in the same Bazel package
as the rest of the code. If we did this, then the bundled `@angular/localize/init`
entry-point code contains all of the helper code, even though most of it is not used.
Equally it is not possible to have the `$localize` types (i.e. `LocalizeFn`
and `TranslateFn`) defined in the `@angular/localize/init` entry-point because
these types are needed for the runtime code, which is inside the primary
entry-point. Importing them from `@angular/localize/init` would run the
side-effect.
The solution is to have a Bazel sub-package at `//packages/localize/src/localize`
which contains these types and the `$localize` function implementation.
The primary `//packages/localize` entry-point imports the types without
any side-effect.
The secondary `//packages/localize/init` entry-point imports the `$localize`
function and attaches it to the global scope as a side-effect, without
bringing with it all the other utility functions.
BREAKING CHANGES:
The entry-points have changed:
* To attach the `$localize` function to the global scope import from
`@angular/localize/init`. Previously it was `@angular/localize`.
* To access the `loadTranslations()` and `clearTranslations()` functions,
import from `@angular/localize`. Previously it was `@angular/localize/run_time`.

In ngcc's reflection host for UMD and CommonJS bundles, custom logic is
present to resolve import details of an identifier. However, this custom
logic is unable to resolve an import for an identifier inside of
declaration files, as such files use the regular ESM import syntax.
As a consequence of this limitation, ngtsc is unable to resolve
`ModuleWithProviders` imports that are declared in an external library.
In that situation, ngtsc determines the type of the actual `NgModule`
that is imported, by looking in the library's declaration files for the
generic type argument on `ModuleWithProviders`. In this process, ngtsc
resolves the import for the `ModuleWithProviders` identifier to verify
that it is indeed the `ModuleWithProviders` type from `@angular/core`.
So, when the UMD reflection host was in use this resolution would fail,
therefore no `NgModule` type could be detected.
This commit fixes the bug by using the regular import resolution logic
in addition to the custom resolution logic that is required for UMD
and CommonJS bundles.

In ESM2015 bundles, a class with decorators may be emitted as follows:
```javascript
var MyClass_1;
let MyClass = MyClass_1 = class MyClass {};
MyClass.decorators = [/* here be decorators */];
```
Such a class has two declarations: the publicly visible `let MyClass`
and the implementation `class MyClass {}` node. In #32539 a refactoring
took place to handle such classes more consistently, however the logic
to find static properties was mistakenly kept identical to its broken
state before the refactor, by looking for static properties on the
implementation symbol (the one for `class MyClass {}`) whereas the
static properties need to be obtained from the symbol corresponding with
the `let MyClass` declaration, as that is where the `decorators`
property is assigned to in the example above.
This commit fixes the behavior by looking for static properties on the
public declaration symbol. This fixes an issue where decorators were not
found for classes that do in fact have decorators, therefore preventing
the classes from being compiled for Ivy.
