This commit updates the routes extractor to use the newly exported private `ɵloadChildren` method from the router to executes a `route.loadChildren` callback and return an array of child routes.
See: https://github.com/angular/angular/pull/51818
This commit changes the way that global style updates are applied when using `vite`. When either live-reload or hmr are enabled the styles are replaced in placed (HMR style) without a live-reload.
This fixes an issue were routes could not be discovered automatically in a standalone application.
This is a total overhaul of the route extraction process as instead of using `guess-parser` NPM package, we now use the Angular Router. This enables a number of exciting possibilities for the future which were not possible before.
# How it works?
The application is bootstrapped and through DI injection we get the injector and router config instance and recursively build the routes tree.
The terser build time constant import from the `@angular/compiler-cli` package is no
longer used in the esbuild-based builder. The constants present are already defined
and conditionally added within the build configuration itself. This not only provides
more flexibility but also removes the need to import the package early in the process.
The import is also an expensive import due to it needing TypeScript and being ESM that
needs to be dynamically imported via a function helper to work around current ESM/TypeScript/CommonJS
limitations.
This commit fixes an issue were previously we spawned piscina with `maxThreads` set to `0` which causes it to exit with a non zero error code when there are no routes to prerender.
Now, in the application builder we exit at n earlier stage if there are no routes to prerender.
This commit updates the `ng generate application` to use the esbuild `application` builder. This also updates the schematics to support both `browser` and `application` builders.
BREAKING CHANGE: `rootModuleClassName`, `rootModuleFileName` and `main` options have been removed from the public `pwa` and `app-shell` schematics.
An upcoming change in Angular will allow `style` specified as strings, in addition to a new `styleUrl` property. These changes update the JIT resource transform to support the change.
Newer versions of the babel packages allow for removing some types packages as well as some helper
packages. The `@babel/template` package export used within the CLI is accessible from the `@babel/core`
package which allows removal of `@babel/template` as a direct dependency. Also, the `@babel/plugin-proposal-async-generator-functions`
package has been transitioned to `@babel/plugin-transform-async-generator-functions` due to async generators
being merged into the ECMAScript standard. Minor code cleanup based on the type cleanup was also performed
in the build optimizer babel passes.
The development server proxy configuration file for Webpack supports a `pathRewrite` field that is
not directly supported by the underlying Vite development server when using the application or esbuild-
browser builders. To provide equivalent support, especially for JSON file-based proxy configurations,
the `pathRewrite` field is now converted internally to a proxy `rewrite` function.
When using the Vite-based development server and a custom `index` build option (not `index.html`),
the custom index path will now be used as the root of the development server. This mimics the behavior
of the Webpack-based development server.
The JavaScript generated for the published packages is now using ES2022.
This removes additional downleveling of code that was previously necessary
to use newer features.
The minimum Node.js version of 18.13 provides support for the needed features.
While this change does require a patch to `@bazel/concatjs` to allow the target
to be set to `ES2022`, this patch is now already required by the migration of
the universal repository into the CLI repository.
By setting up a single instance of the `JavaTransformer`, the Vite-based development server will now
have a fixed and controllable number of worker threads available to process prebundling requests. This
avoids a potentially large number of initial worker threads when a new application with a large number
of dependencies is first used with the development server. This is particularly beneficial for web
container setups which may not be able to efficiently handle the number of workers.
Updates the logic that elides `setClassMetadata` calls to also elide `setClassMetadataAsync`. The latter will be emitted when the component uses the new `defer` block syntax.
Updates the logic for removing Angular metadata and pure top-level functions to account for arrow-function-based IIFEs. Currently Angular doesn't generate arrow functions, but it's being explored in https://github.com/angular/angular/pull/51637.
The esbuild-based application builder will now access the project level i18n configuration
as well as the builder `localize`, `duplicateTranslationBehavior`, and `missingTranslationBehavior`
options to construct a full, normalized i18n option structure.
These options are not yet used by the builder but they are now available to access as future
work incrementally adds i18n support.
This removes the util function for express, instead the "CommonEngine" is called directly infuture before this package is final we might rename the "CommonEngine" to something else.
The `ng extract-i18n` command now supports using either the developer preview esbuild-based browser
or application builders. Support for the existing Webpack-based build system has been maintained.
The extraction process will now build the application based on the build target defined builder in
the case of either `@angular-devkit/build-angular:browser-esbuild` and `@angular-devkit/build-angular:application`.
In the case of the application builder, SSR output code generation is disabled to prevent duplicate messages
for the same underlying source code.
BREAKING CHANGE: Node.js v16 support has been removed
Node.js v16 is planned to be End-of-Life on 2023-09-11. Angular will stop supporting Node.js v16 in Angular v17.
