As more and more groups move away from developing traditional monolithic Rails apps and move to developing JS-frontend-rest-backend apps, there will be more new potential Rails users like me. We want to use Rails exclusively for developing REST services. I'm finding it impossible to locate good "getting started" documentation for this class of users. I think there needs to be something like http://edgeguides.rubyonrails.org/getting_started.html
for users that only want to develop REST APIs. Certainly, the docs at http://edgeguides.rubyonrails.org/api_app.html
are really not helpful at all if you don't already know Rails. Even if you do know Rails, there is no step-by-step material on how to build REST APIs.
Can anyone point me to relevant documentation that I've missed?
Are we mistaken in our goal of using Rails for API development only?
Would we be better off using something like Sinatra, where it is much, much easier to get started developing REST APIs?
Thanks for any help!
