With this change we move `XhrFactory` to the root entrypoint of `@angular/commmon`, this is needed so that we can configure `XhrFactory` DI token at a platform level, and not add a dependency between `@angular/platform-browser` and `@angular/common/http`.
Currently, when using `HttpClientModule` in a child module on the server, `ReferenceError: XMLHttpRequest is not defined` is being thrown because the child module has its own Injector and causes `XhrFactory` provider to be configured to use `BrowserXhr`.
Therefore, we should configure the `XhrFactory` at a platform level similar to other Browser specific providers.
BREAKING CHANGE:
`XhrFactory` has been moved from `@angular/common/http` to `@angular/common`.

A previous commit implemented a streamlined performance metric reporting
system for the compiler-cli, controlled via the compiler option
`tracePerformance`.
This commit adds a custom Bazel flag rule //packages/compiler-cli:ng_perf
to the repository, and wires it through to the `ng_module` implementation
such that if the flag is set, `ng_module` will produce perf results as part
of the build. The underlying mechanism of `//:ng_perf` is not exported from
`@angular/bazel` as a public rule that consumers can use, so there is little
risk of accidental dependency on the contents of these perf traces.
An alias is added so that `--ng_perf` is a Bazel flag which works in our
repository.

ngtsc has an internal performance tracing package, which previously has not
really seen much use. It used to track performance statistics on a very
granular basis (microseconds per actual class analysis, for example). This
had two problems:
* it produced voluminous amounts of data, complicating the analysis of such
results and providing dubious value.
* it added nontrivial overhead to compilation when used (which also affected
the very performance of the operations being measured).
This commit replaces the old system with a streamlined performance tracing
setup which is lightweight and designed to be always-on. The new system
tracks 3 metrics:
* time taken by various phases and operations within the compiler
* events (counters) which measure the shape and size of the compilation
* memory usage measured at various points of the compilation process
If the compiler option `tracePerformance` is set, the compiler will
serialize these metrics to a JSON file at that location after compilation is
complete.

The Ivy Language Service uses the compiler's template type-checking engine,
which honors the configuration in the user's tsconfig.json. We recommend
that users upgrade to `strictTemplates` mode in their projects to take
advantage of the best possible type inference, and thus to have the best
experience in Language Service.
If a project is not using `strictTemplates`, then the compiler will not
leverage certain type inference options it has. One case where this is very
noticeable is the inference of let- variables for structural directives that
provide a template context guard (such as NgFor). Without `strictTemplates`,
these guards will not be applied and such variables will be inferred as
'any', degrading the user experience within Language Service.
This is working as designed, since the Language Service _should_ reflect
types exactly as the compiler sees them. However, the View Engine Language
Service used its own type system that _would_ infer these types even when
the compiler did not. As a result, it's confusing to some users why the
Ivy Language Service has "worse" type inference.
To address this confusion, this commit implements a suggestion diagnostic
which is shown in the Language Service for variables which could have been
narrowed via a context guard, but the type checking configuration didn't
allow it. This should make the reason why variables receive the 'any' type
as well as the action needed to improve the typings much more obvious,
improving the Language Service experience.

Currently, when importing `BrowserAnimationsModule`, Angular uses `AnimationRenderer`
as the renderer. When the root view is removed, the `AnimationRenderer` defers the actual
work to the `TransitionAnimationEngine` to do this, and the `TransitionAnimationEngine`
doesn't actually remove the DOM node, but just calls `markElementAsRemoved()`.
The actual DOM node is not removed until `TransitionAnimationEngine` "flushes".
Unfortunately, though, that "flush" will never happen, since the root view is being
destroyed and there will be no more flushes.
This commit adds `flush()` call when the root view is being destroyed.
BREAKING CHANGE:
DOM elements are now correctly removed when the root view is removed.
If you are using SSR and use the app's HTML for rendering, you will need

was added in microsoft/TypeScript#41523. The prior helpers `__spread`
and `__spreadArrays` used the `__read` helper internally, but the helper
is now emitted as an argument to `__spreadArray` so ngcc now needs to
support evaluating it statically. The real implementation of `__read`
reads an iterable into an array, but for ngcc's static evaluation
support it is sufficient to only deal with arrays as is. Additionally,
the optional `n` parameter is not supported as that is only emitted for
array destructuring syntax, which ngcc does not have to support.

BREAKING CHANGE:
Switching default of `emitDistinctChangesOnlyDefaultValue`
which changes the default behavior and may cause some applications which
rely on the incorrect behavior to fail.
`emitDistinctChangesOnly` flag has also been deprecated and will be
removed in a future major release.
The previous implementation would fire changes `QueryList.changes.subscribe`
whenever the `QueryList` was recomputed. This resulted in an artificially
high number of change notifications, as it is possible that recomputing
`QueryList` results in the same list. When the `QueryList` gets recomputed
is an implementation detail, and it should not be the thing that determines
how often change event should fire.
Unfortunately, fixing the behavior outright caused too many existing
applications to fail. For this reason, Angular considers this fix a
breaking fix and has introduced a flag in `@ContentChildren` and
`@ViewChildren`, that controls the behavior.

export class QueryCompWithStrictChangeEmitParent {
@ContentChildren('foo', {
// This option is the new default with this change.
emitDistinctChangesOnly: true,

Tsserver expects `@angular/language-service` to provide a factory function
as the default export (commonjs-style) of the package.
The current implementation side steps TypeScript's import syntax by using
`module.exports = factory`.
This allows the code to incorrectly re-export other symbols:
```ts
export * from './api';
```
which transpiles to:
```js
var tslib_1 = require("tslib");
tslib_1.__exportStar(require("@angular/language-service/api"), exports);
```
Doing this meant that the package now has a runtime dependency on `tslib`,
which is totally unnecessary.
With the proper `export =` syntax, `tslib` is removed, and no other exports
are allowed.

When there are elements in a translated message, the start and end tags
are encoded as placeholders. The names of these placeholders are computed
from the name of the element. For example `<a> will be `START_LINK` and
`</a>` will be `CLOSE_LINK`.
If there are more than one element with the same name, but different attributes,
then the starting placeholder name is made unique.
For example `<a href="a">` would be `START_LINK`, while `<a href="b">` in
the same message would then be called `START_LINK_1`.
But the closing tags will not be made unique since there are no attrbutes;
the always have the same text `</a>`, which will produce, for example,
`CLOSE_LINK`.
Previously, when extracting XLIFF 2 formatted translation files, the closing
tag placeholder names were computed incorrectly from the opening tag
placeholder names. For example `CLOSE_LINK_1`.
This commit strips these `_1` type endings from the start tag placeholder
name when computing the closing tag placeholder name. It also ensures

Previously, injector definitions contained a `factory` property that
was used to create a new instance of the associated NgModule class.
Now this factory has been moved to its own `ɵfac` static property on the
NgModule class itself. This is inline with how directives, components and
pipes are created.
There is a small size increase to bundle sizes for each NgModule class,
because the `ɵfac` takes up a bit more space:
Before:
```js
let a = (() => {
class n {}
return n.\u0275mod = c.Cb({type: n}),
n.\u0275inj = c.Bb({factory: function(t) { return new (t || n) }, imports: [[e.a.forChild(s)], e.a]}),
n
})(),

```js
let a = (() => {
class n {}
return n.\u0275fac = function(t) { return new (t || n) },
n.\u0275mod = c.Cb({type: n}),
n.\u0275inj = c.Bb({imports: [[r.a.forChild(s)], r.a]}),
n
})(),
```
In other words `n.\u0275fac = ` is longer than `factory: ` (by 5 characters)
and only because the tooling insists on encoding `ɵ` as `\u0275`.
This can be mitigated in a future PR by only generating the `ɵfac` property
if it is actually needed.

The compiler performs cycle analysis for the used directives and pipes
of a component's template to avoid introducing a cyclic import into the
generated output. The used directives and pipes are represented by their
output expression which would typically be an `ExternalExpr`; those are
responsible for the generation of an `import` statement. Cycle analysis
needs to determine the `ts.SourceFile` that would end up being imported
by these `ExternalExpr`s, as the `ts.SourceFile` is then checked against
the program's `ImportGraph` to determine if the import is allowed, i.e.
does not introduce a cycle. To accomplish this, the `ExternalExpr` was
dissected and ran through module resolution to obtain the imported
`ts.SourceFile`.
This module resolution step is relatively expensive, as it typically
needs to hit the filesystem. Even in the presence of a module resolution
cache would these module resolution requests generally see cache misses,
as the generated import originates from a file for which the cache has
not previously seen the imported module specifier.
This commit removes the need for the module resolution by wrapping the
generated `Expression` in an `EmittedReference` struct. This allows the
reference emitter mechanism that is responsible for generating the
`Expression` to also communicate from which `ts.SourceFile` the
generated `Expression` would be imported, precluding the need for module
resolution down the road.
PR Close#40948
The import graph scans source files for its import and export statements
to extract the source files that it imports/exports. Such statements
contain a module specifier string and this module specifier used to be
resolved to the actual source file using an explicit module resolution
step. This is especially expensive in incremental rebuilds, as the
module resolution cache has not been primed during program creation
(assuming that the incremental program was able to reuse the module
resolution results from a prior compilation). This meant that all module
resolution requests would have to hit the filesystem, which is
relatively slow.
This commit is able to replace the module resolution with TypeScript's
bound symbol of the module specifier. This symbol corresponds with the
`ts.SourceFile` that is being imported/exported, which is exactly what
the import graph was interested in. As a result, no filesystem accesses
are done anymore.

In Angular programs, changing a file may require other files to be
emitted as well due to implicit NgModule dependencies. For example, if
the selector of a directive is changed then all components that have
that directive in their compilation scope need to be recompiled, as the
change of selector may affect the directive matching results.
Until now, the compiler solved this problem using a single dependency
graph. The implicit NgModule dependencies were represented in this
graph, such that a changed file would correctly also cause other files
to be re-emitted. This approach is limited in a few ways:
1. The file dependency graph is used to determine whether it is safe to
reuse the analysis data of an Angular decorated class. This analysis
data is invariant to unrelated changes to the NgModule scope, but
because the single dependency graph also tracked the implicit
NgModule dependencies the compiler had to consider analysis data as
stale far more often than necessary.
2. It is typical for a change to e.g. a directive to not affect its
public API—its selector, inputs, outputs, or exportAs clause—in which
case there is no need to re-emit all declarations in scope, as their
compilation output wouldn't have changed.
This commit implements a mechanism by which the compiler is able to
determine the impact of a change by comparing it to the prior
compilation. To achieve this, a new graph is maintained that tracks all
public API information of all Angular decorated symbols. During an
incremental compilation this information is compared to the information
that was captured in the most recently succeeded compilation. This
determines the exact impact of the changes to the public API, which
is then used to determine which files need to be re-emitted.
Note that the file dependency graph remains, as it is still used to
track the dependencies of analysis data. This graph does no longer track
the implicit NgModule dependencies, which allows for better reuse of
analysis data.
These changes also fix a bug where template type-checking would fail to
incorporate changes made to a transitive base class of a
directive/component. This used to be a problem because transitive base
classes were not recorded as a transitive dependency in the file
dependency graph, such that prior type-check blocks would erroneously
be reused.
This commit also fixes an incorrectness where a change to a declaration
in NgModule `A` would not cause the declarations in NgModules that
import from NgModule `A` to be re-emitted. This was intentionally
incorrect as otherwise the performance of incremental rebuilds would
have been far worse. This is no longer a concern, as the compiler is now
able to only re-emit when actually necessary.

function was also moved to the same location (since it's a layer on top of the `readPatchedData` function).

For certain generated function calls, the compiler emits a 'PURE' annotation
which informs Terser (the optimizer) about the purity of a specific function
call. This commit expands that system to produce a new Closure-specific
'pureOrBreakMyCode' annotation when targeting the Closure optimizer instead
of Terser.

We currently provide completions for DOM elements in the schema as well
as attributes when we are in the context of an external template.
However, these completions are already provided by other extensions for
HTML contexts (like Emmet). To avoid duplication of results, this commit
updates the language service to exclude DOM completions for external
templates. They are still provided for inline templates because those
are not handled by the HTML language extensions.

In the new behavior Angular cleanups `popstate` and `hashchange` event listeners
when the root view gets destroyed, thus event handlers are not added twice
when the application is bootstrapped again.
BREAKING CHANGE:
Methods of the `PlatformLocation` class, namely `onPopState` and `onHashChange`,
used to return `void`. Now those methods return functions that can be called
to remove event handlers.

This commit updates the type of the `APP_INITIALIZER` injection token to
better document the expected types of values that Angular handles. Only
Promises and Observables are awaited and other types of values are ignored,
so the type of `APP_INITIALIZER` has been updated to
`Promise<unknown> | Observable<unknown> | void` to reflect this behavior.
BREAKING CHANGE:
The type of the `APP_INITIALIZER` token has been changed to more accurately
reflect the types of return values that are handled by Angular. Previously,
each initializer callback was typed to return `any`, this is now
`Promise<unknown> | Observable<unknown> | void`. In the unlikely event that
your application uses the `Injector.get` or `TestBed.inject` API to inject
the `APP_INITIALIZER` token, you may need to update the code to account for
the stricter type.
Additionally, TypeScript may report the TS2742 error if the `APP_INITIALIZER`
token is used in an expression of which its inferred type has to be emitted
into a .d.ts file. To workaround this, an explicit type annotation is needed,
which would typically be `Provider` or `Provider[]`.

The compiler considers template diagnostics to "belong" to the source file
of the component using the template. This means that when diagnostics for
a source file are reported, it returns diagnostics of TS structures in the
actual source file, diagnostics for any inline templates, and diagnostics of
any external templates.
The Language Service uses a different model, and wants to show template
diagnostics in the actual .html file. Thus, it's not necessary (and in fact
incorrect) to include such diagnostics for the actual .ts file as well.
Doing this currently causes a bug where external diagnostics appear in the
TS file with "random" source spans.
This commit changes the Language Service to filter the set of diagnostics
returned by the compiler and only include those diagnostics with spans
actually within the .ts file itself.
Fixes#41032
PR Close#41070
The current logic in the compiler is to bail when there are errors when
parsing a template into an HTML AST or when there are errors in the i18n
metadata. As a result, a template with these types of parse errors
_will not have any information for the language service_. This is because we
never attempt to conver the HTML AST to a template AST in these
scenarios, so there are no template AST nodes for the language service
to look at for information. In addition, this also means that the errors
are never displayed in the template to the user because there are no
nodes to map the error to.
This commit adds an option to the template parser to temporarily ignore
the html parse and i18n meta errors and always perform the template AST
conversion. At the end, the i18n and HTML parse errors are appended to
the returned errors list. While this seems risky, it at least provides
us with more information than we had before (which was 0) and it's only
done in the context of the language service, when the compiler is
configured to use poisoned data (HTML parse and i18n meta errors can be
interpreted as a "poisoned" template).

Currently, when importing `BrowserAnimationsModule`, Angular uses `AnimationRenderer`
as the renderer. When the root view is removed, the `AnimationRenderer` defers the actual
work to the `TransitionAnimationEngine` to do this, and the `TransitionAnimationEngine`
doesn't actually remove the DOM node, but just calls `markElementAsRemoved()`.
The actual DOM node is not removed until `TransitionAnimationEngine` "flushes".
Unfortunately, though, that "flush" will never happen, since the root view is being
destroyed and there will be no more flushes.
This commit adds `flush()` call when the root view is being destroyed.
BREAKING CHANGE:
DOM elements are now correctly removed when the root view is removed. It
is possible that tests could be accidentally relying on the old behavior by
trying to find an element that was not removed in a previous test. If
this is the case, the failing tests should be updated to ensure they

Previously, when `ngcc` encountered an entry-point with a format-path
that pointed to a non-existing or empty file it would throw an error and
stop processing the remaining tasks.
In the past, we used to ignore such format-paths and continue processing
the rest of the tasks ([see code][1]). This was changed to a hard
failure in 2954d1b5ca. Looking at the code
history, the reason for changing the behavior was an (incorrect)
assumption that the condition could not fail. This assumption failed to
take into account the case where a 3rd-party library has an invalid
format-path in its `package.json`. This is an issue with the library,
but it should not prevent `ngcc` from processing other

Currently there are two entry points for the `@angular/language-service`
package:
- `@angular/language-service`
This default entry point is for View Engine LS. Through the redirection
of `main` field in `package.json`, it resolves to
`./bundles/language-service.js`.
- `@angular/language-service/bundles/ivy.js`
This secondary entry point is for Ivy LS.
TypeScript recently changed the behavior of tsserver to allow only package
names as plugin names [1] for security reasons. This means the secondary
entry point for Ivy LS can no longer be used.
We implemented a quick hack in the module resolver (in the extension repo)
to fix this, but the long term fix should be in `@angular/language-service`.
Here, the `main` field in `package.json` is changed to `index.js`, and in the
index file we conditionally load View Engine or Ivy based on the input config.
This eliminates the need for multiple entry points.
As part of this PR, I also removed all source code for View Engine and Ivy
included in the NPM package. Consumers of this package should run the bundled
output and nothing else. This would help us prevent an accidental import that
results in execution of unbundled code.

Some tools (such as Language Server and ng-packagr) only care about
the processed typings generated by ngcc. Forcing these tools to process
the JavaScript files as well has two disadvantages:
First, unnecessary work is being done, which is time consuming.
But more importantly, it is not always possible to know how the final bundling
tools will want the processed JavaScript to be configured. For example,
the CLI would prefer the `--create-ivy-entry-points` option but this would
break non-CLI build tooling.
This commit adds a new option (`--typings-only` on the command line, and
`typingsOnly` via programmatic API) that instructs ngcc to only render changes
to the typings files for the entry-points that it finds, and not to write any
JavaScript files.
In order to process the typings, a JavaScript format will need to be analysed, but
it will not be rendered to disk. When using this option, it is best to offer ngcc a
wide range of possible JavaScript formats to choose from, and it will use the
first format that it finds. Ideally you would configure it to try the `ES2015` FESM
format first, since this will be the most performant.

Currently `NgTemplateOutlet` recreates its view if its template is swapped out or a context
object with a different shape is passed in. If an object with the same shape is passed in,
we preserve the old view and we mutate the previous object. This mutation of the original
object can be undesirable if two objects with the same shape are swapped between two
different template outlets.
The current behavior is a result of a limitation in `core` where the `context` of an embedded

When setting `ngZoneRunCoalescing` to true, `onStable` is not emitted correctly.
the reason is before this commit, the code looks like this:
```
// application code call `ngZone.run()`
ngzone.run(() => {}); // step 1
// inside NgZone, in the OnInvoke hook, NgZone try to delay the checkStable()
function delayChangeDetectionForEvents(zone: NgZonePrivate) {
if (zone.lastRequestAnimationFrameId !== -1) { // step 9
return;
}
zone.lastRequestAnimationFrameId = zone.nativeRequestAnimationFrame.call(global, () => { // step 2
if (!zone.fakeTopEventTask) {
zone.fakeTopEventTask = Zone.root.scheduleEventTask('fakeTopEventTask', () => {
zone.lastRequestAnimationFrameId = -1; // step 3
updateMicroTaskStatus(zone); // step 4
checkStable(zone); // step 6
}, undefined, () => {}, () => {});
}
zone.fakeTopEventTask.invoke();
});
updatemicroTaskStatus(zone);
}
function updateMicroTaskStatus(zone: NgZonePrivate, ignoreCheckRAFId = false) {
if (zone._hasPendingMicrotasks ||
((zone.shouldCoalesceEventChangeDetection || zone.shouldCoalesceRunChangeDetection) &&
zone.lastRequestAnimationFrameId !== -1)) { // step 5
zone.hasPendingMicrotasks = true;
} else {
zone.hasPendingMicrotasks = false;
}
}
function checkStable(zone: NgZonePrivate) {
if (zone._nesting == 0 && !zone.hasPendingMicrotasks && !zone.isStable) { // step 7
try {
zone._nesting++;
zone.onMicrotaskEmpty.emit(null);
...
}
// application ref subscribe onMicroTaskEmpty
ngzone.onMicroTaskEmpty.subscribe(() => {
ngzone.run(() => { // step 8
tick();
});
});
```
and the process is:
1. step 1: application call ngZone.run()
2. step 2: NgZone delay the checkStable() call in a requestAnimationFrame, and also set
zone.lastRequestAnimationFrameId
3. step 3: Inside the requestAnimationFrame callback, reset zone.lastRequestAnimationFrameId first
4. step 4: update microTask status
5, step 5: if zone.lastRequestAnimationFrameId is -1, that means no microTask pending.
6. step 6: checkStable and trigger onMicrotaskEmpty emitter.
7. step 7: ApplicationRef subscribed onMicrotaskEmpty, so it will call another `ngZone.run()` to process
tick()
8. step 8: And this new `ngZone.run()` will try to check `zone.lastRequestAnimationFrameId` in `step 9`
when trying to delay the checkStable(), and since the zone.lastRequestAnimationFrameId is already reset
to -1 in step 3, so this ngZone.run() will run into step 2 again.
9. and become a infinite loop..., so onStable is never emit
in this commit, there is a new flag `zone.isCheckStableRunning` added to
prevent re-entry when `shouldCoaleascing` flag is enabled.

that references a variable from a parent template (`name`):
```
<ng-template let-name="name">

We generate code that looks that looks like. Note how we access `name` through `ctx`:
```js
function template(rf, ctx) {
if (rf & 1) {
const r0 = ɵɵgetCurrentView();
ɵɵelementStart(0, "button", 2);
ɵɵlistener("click", function() {
ɵɵrestoreView(r0);

const ctx_r1 = ɵɵnextContext();
return ctx_r1.log(name_r0);
});

```
This works fine at the moment, because the template context object can't be changed after creation.
The changes in #40360 allow for the object to be changed, which means that the `ctx` reference
inside the listener will be out of date, because it was bound during creation mode.
This PR aims to address the issue by accessing the context inside listeners through the saved
view reference. With the new code, the generated code from above will look as follows:
```js
function template(rf, ctx) {
