G3 is now using RXJS version 7 which makes it possible for the CLI to also be updated to RXJS 7.
NB: this change does not remove all usages of the deprecated APIs.
Closes#24371
Use promise based methods to reduce RXJS usage and boiler-platting.
BREAKING CHANGE: Several changes to the `SchemaRegistry`.
- `compile` method now returns a `Promise`.
- Deprecated `flatten` has been removed without replacement.
The Builder test harness previously used the deprecated `TestProjectHost` to perform a
variety of file operations during builder unit tests. However, the `TestProjectHost` is
deprecated and uses several layers of rxjs to perform the file operations. The test harness
now uses the Node.js `fs` builtin to directly perform the file operations. This removes several
layers of indirection between the harness and the actual underlying file operations. The removal
of the rxjs operation chaining also reduces stack traces and makes debugging test issues less
complicated.
All analytics is now in the @angular/cli package
BREAKING CHANGE: analytics APIs have been removed without replacement from `@angular-devkit/core` and `@angular-devkit/architect`.
The default set of metadata fields provided to all builders executed via the BuilderHarness is controlled programmatically. The BuilderHarness is eventually intended to operate in-memory and without file system access unlike the legacy unit tests. The `cli.cache.enabled` option must therefore be set within the BuilderHarness initialization code. `cli.cache.enabled` set to false provides improved test isolation guarantees by disabling Webpack’s caching.
All TypeScript files have been updated to pass the new eslint-based linting checks. eslint compatible disabling comments have also been added in place of the previous tslint comments.
With this change, the architect can be configured to use a default configuration when it's not provided as part of the target.
Consider the below, where `defaultConfiguration` is configured to `production`. Running `ng build` will be invoked with "production" configuration.
```js
"build": {
"builder": "@angular-devkit/build-angular:browser",
"defaultConfiguration": "production",
"options": {
...
},
"configurations": {
"production": {
...
}
}
}
```
This change integrates the recently introduced internal custom file watching support into the builder test harness. This allows the test harness to directly trigger file changes and allows more comprehensive test isolation for builder watch scenarios.
