DEPRECATED:
The `resolver` argument of the `RouterOutletContract.activateWith` function and the `resolver` field of the `OutletContext` class are deprecated. Passing component factory resolvers are no longer needed. The `ComponentFactoryResolver`-related symbols were deprecated in `@angular/core` package since v13.
PR Close#45597
The current API for `activateWith` uses the deprecated
`ComponentFactoryResolver`. The replacement for this is to use
`EnvironmentInjector`. That is, instead of
```
const factory = componentFactoryResolver.resolveComponentFactory(component);
location.createComponent(factory, location.length, injector);
```
the replacement would be
```
location.createComponent(
component, {index: location.length, injector, environmentInjector});
```

Currently, the only way to specify new providers for a `Route` and the
children is to create a new `NgModule` with those providers and use the
`loadChildren` feature. This is pretty confusing and a wholly indirect
way of accomplishing this task. With this commit, developers will be
able to specify a list of providers directly on the `Route` itself.
These providers will apply the that route and its children.
This feature was inspired by the upcoming standalone components feature.
This ties in there because, as mentioned before, the prior art for lazy
loading configs was to load an `NgModule`. This loaded module contained
new route configs _and_ could specify new providers. Separating those
two concepts, there should be a way to load _just_ some new routes, but
there should also be a way to specify new providers as well (something
you could do in the `NgModule` world and now will be able to do in the
world without any `NgModule` through this feature).

Previously, the following code would fail to compile:
```
let form: FormGroup<{email: FormControl<string | null>}>;
form = fb.group({
email: ['', Validators.required]
});
```
This is because the compiler was unable to properly infer the inner type of `ControlConfig` arrays in some cases. The same issue applies to `FormArray` as well under certain circumstances.
This change cleans up the `FormBuilder` type signatures to always use the explicit Element type, and to catch `ControlConfig` types that might fall through.

Servers always decode + as a space, which is undesirable when one
actually wants to query for a plus.
BREAKING CHANGE:
Queries including + will now actually query for + instead of space.
Most workarounds involving custom codecs will be unaffected.
Possible server-side workarounds will need to be undone.

This commit bundles tests for standalone components that are possible after
previous implementation commits. Most new tests are compliance tests, but
a test is also included to validate that the template type-checking system
can work with standalone components as well.

This commit adds a type field to .d.ts metadata for directives, components,
and pipes which carries a boolean literal indicating whether the given type
is standalone or not. For backwards compatibility, this flag defaults to
`false`.
Tests are added to validate that standalone types coming from .d.ts files
can be correctly imported into new standalone components.

The ngcc integration test is in an awkward state: it's attempting to test
that the current ngcc can process @angular/core at v12. We need to make a
forwards-incompatible change to the typings of @angular/core, which means
that the compiled typings from the current ngcc won't be compatible with
core as of v12.
To get around this and allow the integration test to have some value, we're
disabling library checking for the time being.

This commit propagates the `isStandalone` flag for a component, directive,

allows the linker to properly process a standalone declaration that it

Standalone component scopes were first implemented in the
`ComponentDecoratorHandler` itself, due to an assumption that "standalone"
allowed for a localized analysis of the component's dependencies. However,
this is not strictly true. Other compiler machinery also needs to understand
component scopes, including standalone component scopes. A good example is
the template type-checking engine, which uses a `ComponentScopeReader` to
build full metadata objects (that is, metadata that considers the entire
inheritance chain) for type-checking purposes. Therefore, the
`ComponentScopeReader` should be able to give the scope for a standalone
component.
To achieve this, a new `StandaloneComponentScopeReader` is implemented, and
the return type of `ComponentScopeReader.getScopeForComponent` is expanded
to express standalone scopes. This cleanly integrates the "standalone"
concept into the existing machinery.

This commit adds an emit for standalone components of the

This commit expands on the unified dependency tracking in the previous
commit and adds tracking of NgModule dependencies. These are not used for
standard components, but are emitted for standalone components to allow the

Previously, the compiler tracked directives and pipes in template scopes
separately. This commit refactors the scope system to unify them into a
single data structure, disambiguated by a `kind` field.
PR Close#45672
Previously, the compiler would represent template dependencies of a
component in its component definition through separate fields (`directives`,
`pipes`).
This commit refactors the compiler/runtime interface to use a single field
(`dependencies`). The runtime component definition object still has separate
`directiveDefs` and `pipeDefs`, which are calculated from the `dependencies`
when the definition is evaluated.
This change is also reflected in partially compiled declarations. To ensure
compatibility with partially compiled code already on NPM, the linker
will still honor the old form of declaration (with separate fields).

`PipeSymbol` contains logic to detect changes in the public API surface of
pipes, which includes the pipe name. However, the pipe handler inadvertently
uses the pipe class name instead of the actual pipe name to initialize the
`PipeSymbol`, which breaks incremental compilation when pipe names change.
There is a test which attempts to verify that this logic is working, but the
test actually passes for a different reason. The test swaps the names of 2
pipes that are both used in a component, and asserts that the component is
re-emitted, theoretically because the public APIs of the pipes is changed.
However, the emit order of the references to the pipes depends on the order
in which they match in the template, which changes when the names are
swapped. This ordering dependency is picked up by the semantic dependency
tracking system, and is what actually causes the component to be re-emitted
and therefore the pipe test to pass in spite of the bug with name tracking.
This commit fixes the `PipeSymbol` initialization to use the correct pipe
name. The test is still flawed in that it's sensitive to the ordering of
pipe emits, but this ordering is due to change soon as a result of the
standalone components work, so this issue will be resolved in a future
commit.

This wasn't exactly possible before because the `RouterConfigLoader` was
not an Injectable so there wasn't a straightforward way to share
information between `ApplyRedirects` and the preloader. They each had
their own implementation so they needed to store the values on the
`Route` so they both had access to them. I imagine this was the case
because trying to inject `Router` (to get access to the events) into the
preloader would have caused a circular dependency.
This refactor co-locates the loading details with the loader itself
rather than leaking implementation into the public route config and
mutating the object in an awkward way. This also promotes
`RouterConfigLoader` to a proper `Injectable` so data can be shared
throughout the system.

This commit implements the `destroy` method on the `ApplicationRef` class. This feature is a preparation for the new logic to bootstrap (and teardown) standalone components (without going through the `NgModuleRef` destroy), which would return an instance of the `ApplicationRef` (the current bootstrap APIs return an instance of the `NgModuleRef`).

The `EnvironmentInjector` should be used instead of `Injector` for the
lazy loading. A future refactor will further update `RouterOutlet` to
use this injector to create the component rather the deprecated
`ComponentFactoryResolver`.
PR Close#45671
In the standalone world, these concepts will no longer be one and the
same. You can load routes without them being inside an `NgModule` with
`RouterModule.forChild`. In addition, routes will be able to define
their own providers, which will be included in an injector that is not
necessarily lazy loaded.
PR Close#45593
The `Injector` is really the piece of information that the `Router` is
interested in keeping track of. Storing the `NgModuleRef` is somewhat
confusing based on how it's used later on. `RouterOutlet` uses it for the
`componentFactoryResolver`, but this is not needed anymore (and deprecated). In
fact, we can get back to the `NgModuleRef` anyways using the injector.
For now, that's what this change does. A different refactor will remove
the use of the `componentFactoryResolver` altogether.
Additionally, in the standalone world, we plan to implement a feature to
allow defining `providers` directly on the `Route`. This means there
won't be an associated `NgModuleRef` so this refactor prepares for that
feature.

This commit adds a new internal scope to `R3Injector` for
`EnvironmentInjector`s specifically. This will allow us to scope services to
the environment side of the injector hierarchy specifically, as opposed to
the `'any'` scope which also includes view-side injectors created via
`Injector.create`. For now, this functionality is not exposed publicly, but
is available to use within `@angular/core` only.
PR Close#45626
This commit exposes a new `EnvironmentInjector` abstraction, which
generalizes the "module injector" concept to injectors that are not based on
NgModules.
An EnvironmentInjector is a conceptual analogue of an `NgModuleRef` - it
represents an injector on the former "module" DI hierarchy in Angular (now
renamed to the "environment injector hierarchy"). Environment injectors are
created via the `createEnvironmentInjector` function from a list of
`Provider`s.
For backwards compatibility with current code using `NgModuleRef`,
`EnvironmentInjector`s are wrapped by an adapter `NgModuleRef`
implementation, so injecting `NgModuleRef` always returns the latest
`EnvironmentInjector`, even if that injector was not based on an NgModule.
Conversely, NgModule-based `NgModuleRef`s created via `createNgModuleRef`
are _also_ `EnvironmentInjector`s.

This commit implements the `importProvidersFrom` function that allows

token which is used to run initialization logic when an injector is created.

Previously there was a test ordering issue with the application_module_spec
tests where the value of `getLocaleId()` depended on the order in which
tests ran. Specifically, `setLocaleId()` lower-cases the current locale ID,
so the measured value in a test depended on whether a previous test had
called `setLocaleId()` (the difference between 'en-US' and 'en-us').
