The i18n option creation for a project, which is a combination of the `i18n` project field and the `localize`
build option, is now in a separate file from the Webpack specific i18n configuration setup.
This allows the i18n option creation to be used without loading anything Webpack specific.
The i18n inlining worker code was previously imported in several locations to allow
reuse of the options object used to configure the worker. To prevent the worker
code from being used outside of an actual worker, the options object definition is
now located in a separate file and imported in both the worker and any other files
that need to use the inlining options.
This commit changes how we set the `LOCALE_ID` when using the `localize` option
- We now include the locale setting snippet only in the main bundle.
- We use `globalThis` to set the the value globally and be accessible across module boundaries. This is important as in some causes such as when using MF `@angular/core` can be located in a bundles others than `main` and `vendor`.
Remove deprecated support for ES5 output.
BREAKING CHANGE: Producing ES5 output is no longer possible. This was needed for Internet Explorer which is no longer supported. All browsers that Angular supports work with ES2015+
Prepares the `@angular-devkit/build-angular` package for the eventual change of enabling the
TypeScript `useUnknownInCatchVariables` option. This option provides additional
code safety by ensuring that the catch clause variable is the proper type before
attempting to access its properties. Similar changes will be needed in the other
packages in the repository prior to enabling `useUnknownInCatchVariables`.
Previously, we used to delete the temporary emitted JS and map files. However this causes a problem in watch mode, as Webpack will not re-emit these deleted files during the next incremental re-build.
With this change we now delete the entire temporary directory when the process is being terminated instead of a file by file bases.
Closes#22395
Temporary JavaScript application files that have been queued for i18n processing are now removed immediately after reading their content. This reduces the on-disk size of temporary files as well as reduces the needed disk access during the final asset copy phase of the i18n inlining process. Additional debug logging has also been added to the i18n inlining process which can be enabled via the `NG_DEBUG=1` environment variable.
Stopping the workers can be a potentially lengthy process with a multi-stage approach based on the state of the worker. This can cause lengthy blocking of the build. This change allows the shutdown to happen in parallel to the remainder of the build.
