Angular CLI support for Bazel

Provides an Angular CLI Builder, which can execute Bazel when triggered by ng build, ng test, etc. See https://angular.io/guide/cli-builder for more info about Builders.

This package is a replacement for parts of the deprecated @angular/bazel package previously maintained by the Angular team.

This builder assumes you have already created Bazel configurations (WORKSPACE and BUILD files). There is presently no tooling to generate these automatically that's supported by either Angular team or rules_nodejs maintainers. See the @bazel/create package for a quickstart to creating a Bazel workspace, or look at examples in rules_nodejs.

To use it, you would just install this package (it doesn't hook into ng add because it has no schematics):

$ npm install --save-dev @angular-builders/bazel

Then edit your angular.json to invoke Bazel. For example, to have ng build do bazel build //:all you would edit the architect block to have:

"architect": {
  "build": {
    "builder": "@angular-builders/bazel:build",
    "options": {
      "targetLabel": "//:all",
      "bazelCommand": "build"
    }
  }
}
