Create it as a normal component withen a kind
components: [
{kind: "Lawnchair", name: "storage"}
]
this.$.storage.add({some: "json"}, enyo.bind(this, function() {}));
this.$.storage.get("key", enyo.bind(this, function(record) {
/*Do something with data*/
}));
You can add in plugins and adapters by making the same calls you would normally with lawnchair
