DEPRECATED: `@angular-devkit/build-optimizer`
It's functionality has been included in `@angular-devkit/build-angular` so this package is no longer needed by the CLI and we will stop publishing the package soon. It has been an experimental (never hit `1.0.0`) and internal (only used by Angular itself) package and should be not be used directly by others.
rules_nodejs 4 requires that a package_name property be specified within a ts_library rule for the output to be linked into the package repository. Failing to add the property can cause test failures due to unresolved packages.
The `no-useless-escape` eslint rule has now been enabled which removes unneeded characters and complexity from string literals and regular expressions. All files that were in violation of this rule have also been corrected.
The dev-infra tooling now directly provides public API change testing capabilities that leverage the `api-extractor` utility. These new testing capabilities are shared with framework and components.
`ts-api-guardian` has been removed as a dependency as a result.
With the support of TypeScript 4.3 within the Angular framework, the CLI now supports using TypeScript 4.3 as well. TypeScript 4.2 also continues to be supported for existing projects.
With this change we update to `webpack` to `5.38.1`, this also updates `webpack-sources` to `2.3.0`, The latter is causing OOM errors on our CI, but it in real projects the memory usage only increased by a small fraction. Also, the OOM errors don't manifest themselves when the entire test suit is run locally.
Therefore with this change we also disable sourcemap genertation for most of the browser builds to speed up the tests and reduce memery usage.
All TypeScript files have been updated to pass the new eslint-based linting checks. eslint compatible disabling comments have also been added in place of the previous tslint comments.
