This change aligns with the supported Node.js versions of the Angular CLI.
See: https://github.com/angular/angular-cli/pull/24026
BREAKING CHANGE: Angular no longer supports Node.js versions `14.[15-19].x` and `16.[10-12].x`. Current supported versions of Node.js are `14.20.x`, `16.13.x` and `18.10.x`.

Currently, there's no check if the task (that is being canceled) has the right state.
Only `scheduled` and `running` tasks can be canceled. If the task has a non-appropriate
state, then an error will be thrown. Cancelation should not throw an error on an already
canceled task, e.g. `clearTimeout` does not throw errors when it's called multiple times
on the same timer.

In AOT compilations, the `strictInjectionParameters` compiler option can
be enabled to report errors when an `@Injectable` annotated class has a
constructor with parameters that do not provide an injection token, e.g.
only a primitive type or interface.
Since Ivy it's become required that any class with Angular behavior
(e.g. the `ngOnDestroy` lifecycle hook) is decorated using an Angular
decorator, which meant that `@Injectable()` may need to have been added
to abstract base classes. Doing so would then report an error if
`strictInjectionParameters` is enabled, if the abstract class has an
incompatible constructor for DI purposes. This may be fine though, as
a subclass may call the constructor explicitly without relying on
Angular's DI mechanism.
Therefore, this commit excludes abstract classes from the
`strictInjectionParameters` check. This avoids an error from being
reported at compile time. If the constructor ends up being used by
Angular's DI system at runtime, then the factory function of the
abstract class will throw an error by means of the `ɵɵinvalidFactory`
instruction.
In addition to the runtime error, this commit also analyzes the inheritance
chain of an injectable without a constructor to verify that their inherited
constructor is valid.
BREAKING CHANGE: Invalid constructors for DI may now report compilation errors
When a class inherits its constructor from a base class, the compiler may now
report an error when that constructor cannot be used for DI purposes. This may
either be because the base class is missing an Angular decorator such as
`@Injectable()` or `@Directive()`, or because the constructor contains parameters
which do not have an associated token (such as primitive types like `string`).
These situations used to behave unexpectedly at runtime, where the class may be
constructed without any of its constructor parameters, so this is now reported
as an error during compilation.
Any new errors that may be reported because of this change can be resolved either
by decorating the base class from which the constructor is inherited, or by adding
an explicit constructor to the class for which the error is reported.

This commit exports existing utility functions to check for control instances:
isFormControl, isFormGroup, isFormRecord, isFormArray
Those are useful when implementing validators that use the specifics of one of those control types.
To narrow down the type to what it actually is, we can now use the util functions in validators:
```
export const myArrayValidator: ValidatorFn = (control) => {
if (!isFormArray(control)) { return null; }
// now you can use FormArray-specific members, e.g.:
if (control.controls.every(c => !!c.value) {
return { myerror: true }
} else { return null; }
}

This commit switches `provideRouter()` to return the new
`EnvironmentProviders` wrapper type, preventing it from being accidentally
(or intentionally) included in `@Component.providers`.
PR Close#47669
This commit introduces a new type `EnvironmentProviders` which can be used
in contexts where Angular accepted `Provider`s destined for
`EnvironmentInjector`s. This includes contexts such as `@NgModule.providers`
and `Route.providers`.
The new type is useful for preventing such providers from accidentally
ending up in `@Component.providers`. It can be used as the return type of
provider functions (such as `provideRouter`) to enforce this safety.
Because `Provider` allows `any[]` nested arrays, the compile-time safety
provided by `EnvironmentProviders` is easily circumvented. However, the
runtime shape of `EnvironmentProviders` is not compatible with component
injectors and will result in a runtime error if it leaks through (NG0207).
A new function `makeEnvironmentProviders` is used to construct this new type
from an array of providers.
The existing `importProvidersFrom` operation previously returned a very
similar type `ImportedNgModuleProviders` which had the same goal. This
machinery is switched over to use the new `EnvironmentProviders` interface
instead (in fact, `ImportedNgModuleProviders` is now just an alias to
`EnvironmentProviders`).

This commit modifies `R3Injector` and other code in Angular that deals with

`EnvironmentProviders` as a public feature.

Previously when a file was being analyzed to determine if a shim should
be generated, up to two calls to the host `fileExists` function per file
per generator were made. In the default host, each `fileExists` call made
two underlying file system calls. Following these calls, the file was then
read via `getSourceFile`. However, `getSourceFile` will return `undefined`
if the requested file does not exist. As a result, `getSourceFile` can be
used directly to request both potential file names and leverage the return
value to determine if the file does not exist. This avoids the need to call
`fileExists` at all.

`HttpXsrfTokenExtractor` allows returning `string|null` for an XSRF token,
and the interceptor checked if the returned token is `null`. However, some
implementations return `undefined` instead (behind an `any`) type, which
caused the interceptor to crash when trying to set an `undefined` value for
the header.
This commit makes the XSRF interceptor a little more resilient against such
broken implementations of the `HttpXsrfTokenExtractor` interface.

Ordinarily, providing `HttpClient` (either via `provideHttpClient` or the
`HttpClientModule`) creates an entirely separate HTTP context. Requests made
via that client are not passed through the interceptor chains that are
configured in a parent injector, for this example.
This commit introduces a new option for `provideHttpClient` called
`withRequestsMadeViaParent()`. When this option is passed, requests made in
the child context flow through any injectors, etc. and are then handed off
to the parent context.
This addresses a longstanding issue with interceptors where it's not
possible to extend the set of interceptors in a child context without
repeating all of the interceptors from the parent.
PR Close#47502
This commit introduces a new feature for `provideHttpClient` called
`withInterceptors`. This feature exposes and configures the new concept of
functional interceptors.
Functional interceptors use functions instead of classes to implement an
HTTP interceptor. Such interceptor functions have access to the DI context
from the `EnvironmentInjector` in which they're configured via the
`inject()` function. Otherwise, functional interceptors are identical in
capability to the existing interceptor system.

This commit introduces the main components of the `provideHttpClient()`
provider API, designed in the style of `provideRouter()`. Initial features
are defined for including legacy class-based interceptors, JSONP support,
and configuring or disabling the builtin XSRF protection.
This API is an alternative to providing `HttpClient` via the
`HttpClientModule`, and is more tree-shakable and more capable than the
NgModule implementation.
Tests are included to validate the new configuration format as well as the
interoperability of the two styles of providing and configuring
`HttpClient`.

these tokens, and will rely on injecting them from either the parent context
or from these root providers.
