Open index.html after compilation to see results (you have to use fastOptJS first).

Install angular dependencies.

npm install

Use it for fast code checking.

sbt
fastOptJS

sbt
fullOptJS

npm start

By adding a prefix ~ to fastOptJS or fullOptJS your code will be tracked for changes and compiled automatically. When you are using lite-server (npm start), then site is reloaded automatically after recompilation.
