Name says it all.

Ember Data Local Storage Adapter

Store your ember application data in localStorage.

Compatible with Ember Data 1.0alpha+.

NOTE: New versions of the localStorage adapter are no longer compatible with older versions of Ember Data. For older versions, checkout the legacy branch.

Usage

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

App.LSAdapter = DS.LSAdapter.extend({
	namespace: 'app_namespace'
});

App.ApplicationAdapter = DS.LSAdapter;

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
