By leveraging the chunks function filter option, the test option can be reduced to only a regular expression instead of the more complex function. This change also provides support for Webpack 5.
Multiple Webpack plugins are only used when certain options are enabled. By only requiring them when needed, startup time can be reduced by potentially eliminating large dependency hierarchies from being loaded that will then be unused. This change currently only applies to plugins that are required. This limitation is due to the current webpack configuration infrastructure being synchronous which prevents dynamic import usage.
This commit makes a few minor changes to enable syncing the CLI repository
into google3.
1. mark pkg_tar and pkg_npm as external
2. remove dependencies (marked as comment) which are stale in google3
3. remove TS files generated from JSON schema in BUILD files since these
files are compiled and added to the g3 codebase at sync time
4. Some minor typing changes
5. Remove duplicate licenses
6. mark dependencies which are not available in g3 as external
7. Immediately type the result of JSON.parse() as required by g3 linter.
Otherwise, the type defaults to `any`.
If no translation parsers could parse a translation-file
we displayed a generic error, which makes it difficult to
track down if there is a problem with the file.
https://github.com/angular/angular/pull/37909 introduces
a new `parser.analyze()` API that allows us to get hold
of the diagnostic messages from trying to parse the
translation-files.
This commit will render these messages if none of the
translation parsers are succcesful.
Note that in order to maintain compatibility with versions
of `@angular/localize` that do not have the `analyze()`
method, the commit includes a polyfill, which can be removed
after a release where we can guarantee that the method
will be available.
This change prevents webpack from removing the operator add imports from the rxjs package (for example, `import 'rxjs/add/operator/filter';`). The entire rxjs package is currently marked as side effect free from within the rxjs `package.json` but the files in the add directory intentionally contain side effects.
This change prevents import statements from being added to commonjs files when downleveling helpers are needed. These imports would then cause webpack to assume that the file is an ES module and potentially break the commonjs file.
Fixes#18284
