This tutorial should be used to develop apps that will most likely not be shipped with the server. So there's no need to include the compiled js.
We should avoid including the js in the repo when possible because:
- It leads to conflicts on rebases that would otherwise be smooth.
- It requires rebuilding the js as a production build for every pull request.
- It requires additional consistency checks in ci to ensure js is updated.
- It increases the repo size significantly.
