An experimental browser application builder (`browser-esbuild`) has been introduced that leverages esbuild as the bundler.
This new builder is compatible with options of the current browser application builder (`browser`) and can be enabled
for experimentation purposes by replacing the `builder` field of `@angular-devkit/build-angular:browser` from an existing
project to `@angular-devkit/build-angular:browser-esbuild`. The builder will generate an ESM-based application and
provides support for ES2015+ compatible output with ES2020 as the default.
This builder is considered experimental and is not recommended for production applications.
Currently not all `browser` builder options and capabilities are supported with this experimental builder.
Additional support for these options may be added in the future.
The following options and capabilities are not currently supported:
* Stylesheet Preprocessors (only CSS styles are supported)
* Angular JIT mode (only AOT is supported)
* Localization [`localize`]
* Watch and dev-server modes [`watch`, `poll`, etc.]
* File replacements [`fileReplacements`]
* License text extraction [`extractLicenses`]
* Bundle budgets [`budgets`]
* Global scripts [`scripts`]
* Build stats JSON output [`statsJson`]
* Deploy URL [`deployURL`]
* CommonJS module warnings (no warnings will be generated for CommonJS package usage)
* Web Workers
* Service workers [`serviceWorker`, `ngswConfigPath`]
The string helpers are predominantly used within schematics that will already depend and import from
the `@angular-devkit/schematics` package. By re-exporting from `@angular-devkit/schematics`, the need
to directly depend and import `@angular-devkit/core` within a schematic can be reduced and in many
cases eliminated.
The `glob`-based check when adding the sourcemap support packages to the karma setup was incorrectly
skipping the files due to Windows pathing issues. The `glob`-based check, however, is unneeded due
to the already present `require.resolve` checks for the sourcemap support packages which will
throw if the packages are not present.
This is not needed as inputs are typed checked to be `JsonValue`. With this change we get a step closer to remove `fast-json-stable-stringify` dependency.
The `_resolveReferenceString` abstract method of the `FileSystemEngineHostBase` class now has a third parameter
that provides the collection description of the schematic currently being resolved. This allows the resolver to
use any fields/options present within the collection description to adjust the resolution of the schematic. The
`encapsulation` optional field is also added to the `FileSystemCollectionDescription` type which will in the future
allow control of the `@angular/cli` VM context wrapping on an individual schematic collection basis.
During the build initialization phase, many paths are converted back and forth between multiple normalized forms. These conversions involve potentially expensive string operations. The majority of the custom path `normalize` function from `@angular-devkit/core` usages have now been removed in favor of the Node.js builtin path functions. This change reduces the need to perform additional string manipulation where possible.
Without the `node_modules` prefix, projects named the same as the excluded package names ex: `webpack` will not compile successfully as all files under the mentioned project will be excluded from being requested by the respective loaders.
Closes#22902
With this change we deprecate exception classes that are not used in the CLI repo.
DEPRECATED:
- `ContentHasMutatedException`, `InvalidUpdateRecordException`, `UnimplementedException` and `MergeConflictException` symbol from `@angular-devkit/core` have been deprecated in favor of the symbol from `@angular-devkit/schematics`.
- `UnsupportedPlatformException` - A custom error exception should be created instead.
These changes include fixes to tests, timeout and stop of architect to make tests work with Jasmine 4.
One noticeable change that when we didn't stop architect through `run.stop()` this causes Bazel to timeout now.

With this change we replace the custom dimension 8 `AOT Enabled`, with `Angular CLI Major Version`. The motivation behind replacing this dimension is that the there is already an `aot` dimension with id 13 which serves for the same purpose.
More information to why we need a new dimension for the Angular CLI major version can be found #22130Closes#22130
Since Angular 8, the CLI has transformed decorator metadata to a form that can be used by the Angular dependency injector without the TDZ limitations of Typescript's decorator metadata emit feature.
As a result, a JIT application compiled with the CLI no longer requires the reflect metadata polyfill that was provided by `core-js`.
This polyfill was also the last remaining usage of the `core-js` package within `@angular-devkit/build-angular` which allows the `core-js` package to also be removed.
Refs: https://github.com/angular/angular-cli/pull/14473 & https://github.com/angular/angular/pull/37382
BREAKING CHANGE: Reflect metadata polyfill is no longer automatically provided in JIT mode
Reflect metadata support is not required by Angular in JIT applications compiled by the CLI.
Applications built in AOT mode did not and will continue to not provide the polyfill.
For the majority of applications, the reflect metadata polyfill removal should have no effect.
However, if an application uses JIT mode and also uses the previously polyfilled reflect metadata JavaScript APIs, the polyfill will need to be manually added to the application after updating.
To replicate the previous behavior, the `core-js` package should be manually installed and the `import 'core-js/proposals/reflect-metadata';` statement should be added to the application's `polyfills.ts` file.
`inquirer` has a number of depedencies which slow down module resolution when importing (~138ms) by lazy loading this module we remove this overhead when prompts are not needed.
The return value of `listSchematicNames` will include hidden schematics when is invoked with true as first parameter.
By default, hidden schematics are not returned.
.substr() is deprecated so we replace it with .slice() which works similarily but isn't deprecated
