There is no need to check that the `ref.node` is of any particular type
because immediately after this check the entry is tested to see if it passes
`isClassDeclarationReference()`.
The only difference is that the error that is reported is slightly different
in the case that it is a `ref` but not one of the TS node types.
Previously:
```
`Value at position ${idx} in the NgModule.${arrayName} of ${
className} is not a reference`
```
now
```
`Value at position ${idx} in the NgModule.${arrayName} of ${
className} is not a class`
```
Arguably the previous message was wrong, since this entry IS a reference
but is not a class.

When ngcc is configured to run with the `--use-program-dependencies`
flag, as is the case in the CLI's asynchronous processing, it will scan
all source files in the program, starting from the program's root files
as configured in the tsconfig. Each individual root file could
potentially rescan files that had already been scanned for an earlier
root file, causing a severe performance penalty if the number of root
files is large. This would be the case if glob patterns are used in the
"include" specification of a tsconfig file.
This commit avoids the performance penalty by keeping track of the files
that have been scanned across all root files, such that no source file
is scanned multiple times.

Previously, the `isCommitClosingPullRequest()` method (used in
`ng-dev release` to detect whether a commit is closing a PR based on
keywords found in the commit message) was only able to detect a subset
of the keywords supported by GitHub.
This is fine currently, because the merge script adds `PR Close #XYZ`
when merging a PR, but it might break in the future.
This commit makes the code more robust by ensuring the method can detect
all keywords supported by GitHub for automatically closing a PR based on
a commit message.

In #39135, the commit message string was accidentally changed from a
template literal to a regular string literal. This prevented the
`npmDistTag` variable from being correctly displayed in the error
message.
This commit fixes it by switching it back to a template literal.
NOTE:
This was pointed out in
https://github.com/angular/angular/pull/39135#discussion_r503361412, but
the PR was accidentally merged before the review feedback had been
addressed.

The `ng-dev release publish` command needs to check whether a commit
closed a pull request. This is implemented via checking the commit
message for specific closing keywords referencing the pull request
number.
The regex used previously failed to correctly ensure that the specified
pull request was referenced. For example, it would allow `#12345` to
also match for `#1234`.
This commit fixes the regex.

When working on the docs, it is helpful to run a local instance of the
angular.io app and run scripts that watch both the docs contents and the
app build artifacts to automatically update the running instance on
changes. Typically, this is achieved via the `start` and `docs-watch`
npm scripts. As a convenience, one can run the `serve-and-sync` script,
which runs both in one terminal.
Previously, it was not possible to pass arguments to `ng nerve` (which
is what the `start` script runs under the hood) when running it via
`serve-and-sync`.
This commit adds support for passing any arguments passed to
`serve-and-sync` through to the `start` script. This can be useful for
things like specifying a custom host or port.

Although in SSR we patch the global prototypes with DOM globals

At a high level, the current shadow DOM shim logic works by escaping the content of a CSS rule
(e.g. `div {color: red;}` becomes `div {%BLOCK%}`), using a regex to parse out things like the
selector and the rule body, and then re-adding the content after the selector has been modified.
The problem is that the regex has to be very broad in order capture all of the different use cases,
which can cause it to match strings suffixed with a semi-colon in some places where it shouldn't,
like this URL from Google Fonts `https://fonts.googleapis.com/css2?family=Roboto:wght@400;500&display=swap`.
Most of the time this is fine, because the logic that escapes the rule content to `%BLOCK%` will
have converted it to something that won't be matched by the regex. However, it breaks down for rules
like `@import` which don't have a body, but can still have quoted content with characters that can
match the regex.
These changes resolve the issue by making a second pass over the escaped string and replacing all
of the remaining quoted content with `%QUOTED%` before parsing it with the regex. Once everything
has been processed, we make a final pass where we restore the quoted content.
In a previous iteration of this PR, I went with a shorter approach which narrowed down the
regex so that it doesn't capture rules without a body. It fixed the issue, but it also ended
up breaking some of the more contrived unit test cases. I decided not to pursue it further, because
we would've ended up with a very long and brittle regex that likely would've broken in even weirder
ways.

Updates to rules_nodejs 2.2.0. This is the first major release in 7 months and includes a number of features as well
as breaking changes.
Release notes: https://github.com/bazelbuild/rules_nodejs/releases/tag/2.0.0
Features of note for angular/angular:
* stdout/stderr/exit code capture; this could be potentially be useful
* TypeScript (ts_project); a simpler tsc rule that ts_library that can be used in the repo where ts_library is too
heavy weight
Breaking changes of note for angular/angular:
* loading custom rules from npm packages: `ts_library` is no longer loaded from `@npm_bazel_typescript//:index.bzl`
(which no longer exists) but is now loaded from `@npm//@bazel/typescript:index.bzl`
* with the loading changes above, `load("@npm//:install_bazel_dependencies.bzl", "install_bazel_dependencies")` is
no longer needed in the WORKSPACE which also means that yarn_install does not need to run unless building/testing
a target that depends on @npm. In angular/angular this is a minor improvement as almost everything depends on @npm.
* @angular/bazel package is also updated in this PR to support the new load location; Angular + Bazel users that
require it for ng_package (ng_module is no longer needed in OSS with Angular 10) will need to load from
`@npm//@angular/bazel:index.bzl`. I investigated if it was possible to maintain backward compatability for the old
load location `@npm_angular_bazel` but it is not since the package itself needs to be updated to load from
`@npm//@bazel/typescript:index.bzl` instead of `@npm_bazel_typescript//:index.bzl` as it depends on ts_library
internals for ng_module.
* runfiles.resolve will now throw instead of returning undefined to match behavior of node require
Other changes in angular/angular:
* integration/bazel has been updated to use both ng_module and ts_libary with use_angular_plugin=true.
The latter is the recommended way for rules_nodejs users to compile Angular 10 with Ivy. Bazel + Angular ViewEngine is
supported with @angular/bazel <= 9.0.5 and Angular <= 8. There is still Angular ViewEngine example on rules_nodejs
https://github.com/bazelbuild/rules_nodejs/tree/stable/examples/angular_view_engine on these older versions but users
that want to update to Angular 10 and are on Bazel must switch to Ivy and at that point ts_library with
use_angular_plugin=true is more performant that ng_module. Angular example in rules_nodejs is configured this way
as well: https://github.com/bazelbuild/rules_nodejs/tree/stable/examples/angular. As an aside, we also have an
example of building Angular 10 with architect() rule directly instead of using ts_library with angular plugin:
https://github.com/bazelbuild/rules_nodejs/tree/stable/examples/angular_bazel_architect.
NB: ng_module is still required for angular/angular repository as it still builds ViewEngine & @angular/bazel
also provides the ng_package rule. ng_module can be removed in the future if ViewEngine is no longer needed in
angular repo.
* JSModuleInfo provider added to ng_module. this is for forward compat for future rules_nodejs versions.

The right needs to be wrapped in parens or we cannot accurately match its
span to just the RHS. For example, the span in `e = $event /*0,10*/` is ambiguous.
It could refer to either the whole binary expression or just the RHS.
We should instead generate `e = ($event /*0,10*/)` so we know the span 0,10 matches RHS.
This is specifically needed for the TemplateTypeChecker/Language Service
when mapping template positions to items in the TCB.

PR Close#39124
The expression parser already has support for recovering on malformed
property reads, but did not have tests describing the recovered ast in
such cases. This commit adds tests to demonstrate such cases; in
particular, the recovered ast is a full PropertyRead but with an empty
property name. This is likely the most preferred option, as it does not
constrain consumers of the AST to what the property name should look
like. Furthermore, we cannot mark the property name as empty in any
other way (e.g. an EmptyExpr) because the property name, as of present,
is a string field rather than an AST itself.
Note that tokens past a malformed property read are not preserved in the
AST (for example in `foo.1234`, `1234` is not preserved in the AST).
This is because the extra tokens do not belong to the singular
expression created by the property read, and there is not a meaningful
way to interpret a secondary expression in a single parsed expression.

This patch refactors the interpolation parser to do so iteratively
rather than using a regex. Doing so prepares us for supporting granular
recovery on poorly-formed interpolations, for example when an
interpolation does not terminate (`{{ 1 + 2`) or is not terminated
properly (`{{ 1 + 2 {{ 2 + 3 }}`).

This patch adds support for recovering well-formed (and near-complete)
ASTs for semantically malformed keyed reads and keyed writes. See the
added tests for details on the types of semantics we can now recover;
in particular, notice that some assumptions are made about the form of
a keyed read/write intended by a user. For example, in the malformed
expression `a[1 + = 2`, we assume that the user meant to write a binary
expression for the key of `a`, and assign that key the value `2`. In
particular, we now parse this as `a[1 + <empty expression>] = 2`. There
are some different interpretations that can be made here, but I think
this is reasonable.
The actual changes in the parser code are fairly minimal (a nice
surprise!); the biggest addition is a `writeContext` that marks whether
the `=` operator can serve as a recovery point after error detection.

width and it had to be wrapped into multiple lines, it was hard to

lines from other headings by reducing the spacing between wrapped lines
of the same heading (making it more obvious that they belong together).
