Grape/Rails API Cross-Origin Resource Sharing

If you want to allow access to your Grape API from other domains, you need to implement CORS!

It’s easy with the rack-cors gem. Here’s how you do it.

Add rack-cors to your gemfile.

gem 'rack-cors', :require => 'rack/cors'

Then go to your application.rb and add:

[gist id="4297940"]https://gist.github.com/4297940

done!
