Ember Data Local Storage Adapter

Store your ember application data in localStorage.

Compatible with Ember Data 1.0.beta.6.

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

Usage

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

App.ApplicationSerializer = DS.LSSerializer.extend();
App.ApplicationAdapter = DS.LSAdapter.extend({
    namespace: 'yournamespace'
});

If you are using Ember Localstorage Adapter within an Ember CLI project you can install it as an addon with the following command:

npm install --save-dev ember-localstorage-adapter

Then in Brocfile.js import it before module.exports:

app.import('bower_components/ember-localstorage-adapter/localstorage_adapter.js');

module.exports = app.toTree();

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'
});

Models

Whenever the adapter returns a record, it'll also return all relationships, so do not use {async: true} in you model definitions.

Namespace

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

• Make the repo nicer to work with long-term (do something more intelligent with dependencies found in vendor, etc.)

Tests

If you don't have bower, install it with

npm install bower -g

Then install the dependencies with

bower install

Open test/index.html in a browser. If you have phantomjs installed, run

phantomjs test/runner.js test/index.html
