Install Bazel from the distribution, see install instructions.
On Mac, just brew install bazel.
Bazel will install a hermetic version of Node, npm, and Yarn when you run the first build.
Also add ibazel to your $PATH:
yarn global add @bazel/ibazel
or
npm install -g @bazel/ibazel
Before building the app, we install packages, just as with any npm-based development workflow. However, to get the same version of the toolchain as co-workers and our continuous integration, let's have Bazel run the package manager using a pinned version it manages. You should not even need node, npm, or yarn installed on a machine where you develop with Bazel.
$ bazel run :installNext we'll run the development server:
$ ibazel run src:devserver
