Example of building an Angular app with Bazel

This is in Alpha and depends on un-released version of Angular. There may be breaking changes.

Mac: brew install bazel

Other platforms, see Bazel installation instructions.

$ bazel run @yarn//:yarn
$ bazel build src

Note: there is a "watch mode" for Bazel available at https://github.com/bazelbuild/bazel-watcher

Notes:

• we use bazel to run yarn simply to be sure we get the same versions of Node and Yarn as CI and co-workers (hermeticity FTW)
• a postinstall task in the package.json prepares the node_modules directory by running the Angular compiler on third_party libraries (such as Angular itself) since these do not ship with generated code (eg. ngfactorys)
