With recent improvements to the dev-server builder unit tests, additional parallel testing should now be possible.
The unused `express` dependencies are also removed.
This change updates the remainder of the non-builder harness tests to use a random port when testing. This change reduces the frequency of test flakes as well as improves the opportunity for parallel test execution.
With the removal of the deprecated ViewEngine-based Webpack plugin, the ivy namespace export that was previously used is now deprecated in favor of direct exports of the Ivy-based plugin.
The default Jasmine test timeout is set to 2.5 minutes for all builder tests. The smaller timeouts (that are now removed from individual tests) can lead to test flakes especially on CI which can have large performance variability.
BREAKING CHANGE:
Removal of deprecated browser and server command options.
- `i18nFile`, use `locales` object in the project metadata instead.
- `i18nFormat`, No longer needed as the format will be determined automatically.
- `i18nLocale`, use `localize` option instead.
BREAKING CHANGE: Removal of deprecated `extract-i18n` command options
The deprecated `i18nLocale` option has been removed and the `i18n.sourceLocale` within a project's configuration should be used instead.
The deprecated `i18nFormat` option has been removed and the `format` option should be used instead.
BREAKING CHANGE: Removal of View Engine support from application builds
With the removal of the deprecated View Engine compiler in Angular version 12 for applications, Ivy-based compilation will always be used when building an application.
The default behavior for applications is to use the Ivy compiler when building and no changes are required for these applications.
For applications that have opted-out of Ivy, a warning will be shown and an Ivy-based build will be attempted. If the build fails,
the application may need to be updated to become Ivy compatible.
The package's `@angular-devkit/core` dependency is only used in non-test code to provide a single type which is no longer needed with the latest architect.
The `json.JsonObject` generic constraint did not force the options type to be a valid JSON object but required all builders to add the `json.JsonObject` type to all builder option types when calling `createBuilder`.
BREAKING CHANGE: Removal of View Engine support from i18n extraction
With the removal of the deprecated View Engine compiler in Angular version 12 for applications, the `ng extract-i18n` command will now always use the Ivy compiler.
The `--ivy` option has also been removed as Ivy-based extraction is always enabled.
The default behavior for applications is to use the Ivy compiler for building/extraction and no changes are required for these applications.
For applications that have opted-out of Ivy, a warning will be shown and Ivy-based extraction will be attempted. If the extraction fails,
the application may need to be updated to become Ivy compatible.
This change improves the performance of incremental type checking of Angular templates by reducing the number of calls to retrieve the diagnostics.
Only the set of affected files will be queried on a rebuild. The affected set includes files TypeScript deems affected, files that
are required to be emitted by the Angular compiler, and the original file for any TTC shim file that TypeScript deems affected.
If an error occurs during a build, it is possible that the output path directory may not be present and then cause the stats JSON file write to fail.
