Ember Data Build Status

Ember Data is a library for loading data from a persistence layer (such as a JSON API), mapping this data to a set of models within your client application, updating those models, then saving the changes back to a persistence layer. It provides many of the facilities you'd find in server-side ORMs like ActiveRecord, but is designed specifically for the unique environment of JavaScript in the browser.

Ember Data provides a central Data Store, which can be configured with a range of provided Adapters, but two core Adapters are provided: the RESTAdapter and FixtureAdapter.

The RESTAdapter is configured for use by default. You can read more about it in the Guides. It provides a fully RESTful mechanism for communicating with your persistence layer, and is the preferred and recommended choice for use with Ember Data.

This is definitely alpha-quality. The basics of RESTAdapter work, but there are for sure edge cases that are not yet handled. Please report any bugs or feature requests, and pull requests are always welcome.

Is It Good?


Is It "Production Ready™"?

No. The API should not be considered stable until 1.0. Breaking changes, and how to update accordingly, are listed in

A guide is provided on the Ember.js site that is accurate as of Ember Data 1.0 beta.
