Chongo

A mongo-like interface to browser Web Storage (localStorage and sessionStorage).

Basic usage

// Connection using sessionStorage, i.e. data is cleaned
//  when the browser is closed.
var con = new Chongo.Connection(sessionStorage);
var db = con.db('todos');   // "todo" database. Created if necesary.
var todo = db.col('todos'); // "todo" collection. Created if necesary.

// The next lines work as you'd expect.
todo.insert({title: "Buy apples.", completed: false});
var oid = todo.insert({title: "Take the trash out.", completed: false});
todo.update({_id: oid}, {completed: true});
var cur = todo.find();
while(cur.hasNext()){
	console.log(cur.next().title)
}

For more on the usage look in the demo and test folders.

Internal behaviour

Each document is stored separately as JSON under a key with the name $.<db name>.<collection name>.$<ObjectId>. An index of the documents in a collection in $natural order is stored under the key $.<db name>.<collection name>.
