I\'m using Ember CLI 0.0.36. When I run ember server in my project folder, my understanding is that a server buried in some Brocoli process gets started. Howeve
I started playing with ember cli so i'm not sure but i found the following: https://github.com/dockyard/ember-cli-plus-backend/tree/rails-served-html/frontend/api-stub Basically you should proxy your express server to the same port as your ember-cli (so then you don't have to deal with jsonp issue)
Set the method to 'proxy' and define the proxyURL to pass all API requests to the proxy URL.
UPDATE:
1.Generate adapter ember generate adapter application
2.Make api namespace - fill the created file with the following code:
export default DS.RESTAdapter.reopen({ namespace: 'api' });
3.Start the server with ember serve --proxy http://localhost:1337/ (this will proxy all your request to localhost:4200 to 1337
4.Make routes in your express app prefixed by /api
Hope it helps
