With Ember Data currently in beta and not production ready (based on the project’s README), I wonder what model layer people are using for Ember applications in a production environment. Do you roll your own or do you use Ember Data? Two alternatives that I am aware of are Ember Model (https://github.com/ebryn/ember-model) and Ember Persistence Foundation (http://epf.io). What is your experience with the solution you’ve chosen for?
I use Ember Data (beta) it works well. this episode of Ember Hotseat covers the 3 persistence libraries you mentioned: http://emberhotseat.com/2013/07/19/ember-hot-seat-episode-007.html it’s from July '13 but does highlight the strengths of each.
We wrote our own modeling after backbone’s simple design.
