Paul Gschwendtner 762e057e85 build: update to rules_nodejs v4.0.0-beta.0 (#42760)
Updates the Bazel NodeJS rules to v4.0.0-beta.0. This is necessary
so that the Angular components repo can update, and it's generally
good to stay as up-to-date as possible with the Bazel rules as it's
easy to fall behind, and updating early allows us to discover issues
affecting our tooling earlier (where they are easier to address due to
e.g. potential breaking change policy).

Paul Gschwendtner 25f763cff8 feat(core): support TypeScript 4.3 (#42022)
Switches the repository to TypeScript 4.3 and the latest
version of tslib. This involves updating the peer dependency
ranges on `typescript` for the compiler CLI and for the Bazel
package. Tests for new TypeScript features have been added to
ensure compatibility with Angular's ngtsc compiler.

Alan Agius ed7d288364 build: update several dependencies (#41434)
With this change we update several dependencies to avoid Renovate creating a lot of PRs during onboarding. We also remove yarn workspaces as after further analysis these are not needed.

Certain dependencies such as `@octokit/rest`, `remark` and `@babel/*` have not been updated as they require a decent amount of work to update, and it's best to leave them for a seperate PR.

Greg Magolan 42a164f522 build: upgrade angular build, integration/bazel and @angular/bazel package to rule_nodejs 2.2.0 (#39182)
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.

Igor Minar 5d3ba8dec7 test: update ts-api-guardian's strip_export_pattern to exclude Ivy instructions (#38224)
Previously the instructions were included in the golden files to monitor the frequency and rate of
the instruction API changes for the purpose of understanding the stability of this API (as it was
considered for becoming a public API and deployed to npm via generated code).

This experiment has confirmed that the instruction API is not stable enough to be used as public
API. We've since also came up with an alternative plan to compile libraries with the Ivy compiler
for npm deployment and this plan does not rely on making Ivy instructions public.

For these reasons, I'm removing the instructions from the golden files as it's no longer important
to track them.

The are three instructions that are still being included: `ɵɵdefineInjectable`, `ɵɵinject`, and
`ɵɵInjectableDef`.

These instructions are already generated by the VE compiler to support tree-shakable providers, and
code depending on these instructions is already deployed to npm. For this reason we need to treat
them as public api.

This change also reduces the code review overhead, because changes to public api golden files now
require multiple approvals.

Paul Gschwendtner a1e00f82f4 build: fix ts-api-guardian golden approval not working on windows (#36115)
Currently on Windows, it's not possible to approve goldens in
`ts-api-guardian`. This is because paths are resolved relatively
to the working directory. In Windows, golden files are resolved
to the actual workspace directory. The current logic tries to
compute a relative path to the runfile from the working directory.

This causes the file paths to have a lot of parent directory
path segments. Eventually, when joined with the build workspace
directory, the paths end up being incorrect. e.g.

```
fileName = ../../../../../../projects/angular/golden/<..>/common.d.ts`
outFile = BUILD_WORKSPACE_DIR + fileName;
```

To fix this, we no longer deal with confusing relative paths, but
instead always use absolute file system paths.

Additionally, this fixes that new goldens are generated at the wrong
location on all platforms.

This is experimental and if `bazel test //:test.debug` fails than `bazel run` is still guaranteed to work as  `BUILD_WORKSPACE_DIRECTORY` will be set in that context

@babel/core dep had to be pinned to 7.6.4 or else //packages/localize/src/tools/test:test failed. Also //packages/localize uses @babel/generator, @babel/template, @babel/traverse & @babel/types so these deps were added to package.json as they were not being hoisted anymore from @babel/core transitive.

NB: integration/hello_world__systemjs_umd test must run with systemjs 0.20.0
NB: systemjs must be at 0.18.10 for legacy saucelabs job to pass
NB: With Bazel 2.0, the glob for the files to test `"integration/bazel/**"` is empty if integation/bazel is in .bazelignore. This glob worked under these conditions with 1.1.0. I did not bother testing with 1.2.x as not having integration/bazel in .bazelignore is correct.

Currently we are showing the following link https://github.com/angular/angular/blob/master/docs/PUBLIC_API.md#golden-files whenever there are updates to the golden files. However this is not correct as this document only applies to the Angular repo as other consumers of ts-api-guardian have different commands, and they store they golden files in different locations.

Greg Magolan dcff76e8b9 refactor: handle breaking changes in rules_nodejs 1.0.0 (#34736)
The major one that affects the angular repo is the removal of the bootstrap attribute in nodejs_binary, nodejs_test and jasmine_node_test in favor of using templated_args --node_options=--require=/path/to/script. The side-effect of this is that the bootstrap script does not get the require.resolve patches with explicitly loading the targets _loader.js file.
