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. Recently, I found a way to use Yeomen generator and rails-api to work as front-end and back-end together.
Here’s some Pros and Cons for this way:

Pros:

• Separate struct and codebase for front-end and back-end
• Get rid of unused rails component like erb view template
• No more need to fresh for front-end change

Cons:

• have to deal with csrf token
• need to setup the proxy
• hard to deploy
