"In-Memory" in persistence.js not working

[carper7]

Hi,

I am looking for a tool that will allow me to store data in local storage and came across persistence.js. I am looking at being able to store the data, create a dump and then restore it to keep working on the same. Based on the github page this plugin allows to do that and more but I am having hard time making it work. I just played with the examples in the github but nothing is created and also get errors when dumping/restoring data. This is what I have so far:

persistence.schemaSync();
var Item = persistence.define('Item', {
ItemId: "TEXT",
Name: "TEXT"
});

var item = new Item();
item.ItemId = "124";
item.Name = "Test1";

persistence.add(item);
persistence.flush( );

persistence.dump(tx, [Item], function(dump) {
console.log(dump);
});

persistence.load(tx, dump, function() {
alert('Dump restored!');
});

Could you please help me out. I would like to store some data in a json file, save it in local storage, create a dump of that json file, and finally restore it in order to keep adding more to it at a later time. These are the libraries I am using in my html file:

<script src='persistencejs/lib/persistence.js'></script>
<script src='persistencejs/lib/persistence.store.memory.js'></script>

<script src='persistencejs/lib/persistence.store.sql.js'></script> <script src='persistencejs/lib/persistence.store.websql.js'></script>

Kind Regards,
