How to setup Angular with Rails

There are a lot of way you can integrate Angular with Rails, a common way is put Angular inside the Asset pipeline. It’s easy to integrate that way but the code base is quite mess at the later point.

Pros:

• Separate struct and codebase for front-end and back-end

• need to setup the proxy
• hard to deploy
