Store JavaScript objects in HTML5 local storage

It is easy enough to pollyfill the localStorage object to store and retrieve objects rather than just strings.

if ( !Storage.prototype.setObject ) {
    Storage.prototype.setObject = function(key, value) {
        this.setItem(key, JSON.stringify(value));
    }
}

if ( !Storage.prototype.getObject ) {
    Storage.prototype.getObject = function(key) {
        var value = this.getItem(key);
        return value && JSON.parse(value);
    }
}

Now we can simply get and set objects from localStorage.

var apps = {
        appName : 'Links app',
        settings : {'type' : 'link'}
};  

localStorage.setObject('apps', apps );

var ourApps = localStorage.getObject('apps');
