Ember Data Local Storage Adapter

Store your ember application data in localStorage.

Currently tested against ember-data revision 11.

Usage

Include localstorage_adapter.js in your app and then like all adapters:

App.store = DS.Store.create({
  revision: 11,
  adapter: DS.LSAdapter.create()
});

Local Storage Namespace

All of your application data lives on a single localStorage key, it defaults to DS.LSAdapter but if you supply a namespace option it will store it there:

DS.LSAdapter.create({
  namespace: 'my app'
});

Model "url"

If your model definition has a url property, the adapter will store the data on that namespace. URL is a weird term in this context, but it makes swapping out adapters simpler by not requiring additional properties on your models.

var List = DS.Model.extend({
  // ...
});
List.reopen({
  url: '/some/url'
});

Quota Exceeded Handler

Browser's localStorage has limited space, if you try to commit application data and the browser is out of space, then the adapter will trigger the QUOTA_EXCEEDED_ERR event.

App.store.adapter.on('QUOTA_EXCEEDED_ERR', function(records){
  // do stuff
});

App.store.commit();

Todo

• Figure out how to save a record once its transitioned to the error state.
• Make the repo nicer to work with long-term (do something more intelligent with dependencies found in vendor, etc.)
• Add some examples
