The `browserTarget` option has been removed as part of the refactoring process. This option was part of a private API and is no longer used. Projects relying on this option should migrate to using the `buildTarget` option. BREAKING CHANGE: The `browserTarget` option has been removed from the DevServer and ExtractI18n builders. `buildTarget` is to be used instead.

/**
|
|
* Main entry point for the migration rule.
|
|
*
|
|
* This schematic migration performs updates to the Angular workspace configuration
|
|
* to ensure that application projects are properly configured with polyfills
|
|
* required for internationalization (`localize`).
|
|
*
|
|
* It specifically targets application projects that use either the `application`
|
|
* or `browser-esbuild` builders.
|
|
*
|
|
* The migration process involves:
|
|
*
|
|
* 1. Iterating over all projects in the workspace.
|
|
* 2. Checking each project to determine if it is an application-type project.
|
|
* 3. For each application project, examining the associated build targets.
|
|
* 4. If a build target's `localize` option is enabled but the polyfill
|
|
* `@angular/localize/init` is missing from the `polyfills` array, the polyfill
|
|
* is automatically added to ensure proper internationalization support.
|
|
*
|
|
* Additionally, this migration updates projects that use the `dev-server` or `extract-i18n`
|
|
* builders to ensure that deprecated `browserTarget` options are migrated to the
|
|
* newer `buildTarget` field.
|
