With this change we remove the usage of hard coded `src` directory and instead infer this from the `sourceRoot` project option.
We also remove the `angularCompilerOptions.entryModule` property in the server tsconfig as this is no longer needed with Ivy.
Closes#12104
With this change we update the TypeScript compilation target to `ES2020` for both new and existing projects. This is because all browsers that Angular supports (https://angular.io/guide/browser-support) support `ES2020` features without the need for polyfills.
The unit-tests where intended to not use build caching to better ensure test isolation. However, the configuration format was incorrect and did not disable the build caching.
Persistent disk build cache is now enabled by default. A number of options have been added to allow fine tuning of the cache.
The options can be configuration in `cli.cache` section in the `angular.json` as shown below.
- `enabled`: Configure whether disk caching is enabled. Defaults to `true`
- `environment`: Configure in which environment disk cache is enabled. Valid values `ci`, `local` or `all`. Defaults to: `local`
- `path`: cache base path. Defaults to `.angular/cache`
DEPRECATED: `NG_BUILD_CACHE` environment variable option will be removed in the next major version. Configure `cli.cache` in the workspace configuration instead.
BREAKING CHANGE: `NG_PERSISTENT_BUILD_CACHE` environment variable option no longer have effect. Configure `cli.cache` in the workspace configuration instead.
```json
{
"$schema": "./node_modules/@angular/cli/lib/config/schema.json",
"version": 1,
"cli": {
"cache": {
"enabled": true,
"path": ".custom-cache-path",
"environment": "all"
}
}
...
}
```
BREAKING CHANGE:
With this change we removed several deprecated builder options
- `extractCss` has been removed from the browser builder. CSS is now always extracted.
- `servePathDefaultWarning` and `hmrWarning` have been removed from the dev-server builder. These options had no effect.
In version 12.1, the framework added the `destroyAfterEach` an opt-in feature that improves tests performance and also addresses two long-standing issues.
The idea, is to have this enabled by default in the future. Related PR: https://github.com/angular/angular/pull/42566Closes#21280
With this change we update to `webpack` to `5.38.1`, this also updates `webpack-sources` to `2.3.0`, The latter is causing OOM errors on our CI, but it in real projects the memory usage only increased by a small fraction. Also, the OOM errors don't manifest themselves when the entire test suit is run locally.
Therefore with this change we also disable sourcemap genertation for most of the browser builds to speed up the tests and reduce memery usage.
With this change we configure new libraries to be published using Ivy partial compilation instead of the deprecated View Engine rendering engine, we also remove several view engine specific `angularCompilerOptions`.
New libraries can be published using this format, as they are not depend upon by View Engine libraries or application.
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.
This is another feature that we mentioned in the Eliminate Render Blocking Requests RFC (#18730)
Inlining of critical CSS is turned off by default. To opt-in this feature set `inlineCritical` to `true`.
Example:
```json
"configurations": {
"production": {
"fileReplacements": [
{
"replace": "src/environments/environment.ts",
"with": "src/environments/environment.prod.ts"
}
],
"optimization": {
"styles": {
"minify": true,
"inlineCritical": true,
}
},
```

In a future version of the Angular CLI `inlineCritical` will be enabled by default.

Currently, Karma is reporting a failed test and the total twice in a bare CLI project:

This is a bit annoying when you have several tests failing, and tend to confuse beginners.
This commit configures the Karma HTML reporter to suppress the duplicates (both error and success), which results in only one reporter showing the failed test and total:

The supported versions of Node.js support up to ES2018, the only reason why we don't use ES2017+ is because native `async` and `await` don't work with zone.js
See: https://github.com/angular/angular/issues/31730
With this change, we also ensure that we don't downlevel the server bundle to ES5 which is unnecessary.
Closes: #17794
With this change we update the target and module settings of various compilation units.
- We replace ES5 target in protractor. Protractor runs on Node.Js which support ES2018
- For applications we now use `ES2020` instead of `ESNext` as a module to avoid unexpected changes in behaviour
This changes also adds a migration to update existing projects and also removes `module` from the Universal tsconfig as per #17352 to enable lazy loading on the server.
BREAKING CHANGE:
The following deprecated devkit builders options have been removed:
- `skipAppShell:` This has no effect
- `evalSourceMap`: This done to improve performance in older versions of the CLI and is no longer needed
- `vendorSourceMap`: Use `sourceMap.vendor` instead
- `profile`: Use `NG_BUILD_PROFILING` environment variable instead
Previously, when using a preprocessor, resources (e.g., `url(./my-image.jpg)`) referenced in a stylesheet that was imported into another stylesheet would retain the exact URL. This would be problematic as the resource would not be at the relative location within the new combined stylesheet. With this change the resource URLs will now be adjusted to reference the origin location of the resource. This allows the resources to be found without any additional changes to the application or build process.
CSS and Less already functioned in this manner. This change brings Sass and Stylus to parity.
Fixes: #12797
