mongodblite

Inspired by meteor

Why?

• I wanted a decoupled library with the same level of functionality provided in meteor
• Cached on the client-side, and server-side. Less hits to mongodb itself.
• Allows for users to be sandboxed in their own collection (authentication).
• listening to cursors for any change

TODO

• fork mongoose ODM and use this as the default driver
• REST interface mapper
• sync items to backend (persistence api)
• rest gateway example
• DNode driver
• Http driver
• object modifiers: $inc, $set, $unset, $push $pushAll, $addToSet, $pop, $pull, $pullAll, $rename, $bit (should be separate repo - fiddle?)
• cursor.emit("update") when limit, selector, or skip have changed

Examples

Here's a simple example using the memory driver:

 
var mdblite = require('mongodblite'),
db = mdblite.db(new mdblite.drivers.Memory());
 
 
var people = db.collection('people');
 
//add some data
people.insert([
    {
        name: "Craig",
        age: 22
    },
    {
        name: "Tim",
        age: 21
    },
    {
        name: "John",
        age: 20
    }
}
]);
 
//create a filter against the "people" collection
var peopleOlderThan21 = people.find({age:{$gt:21}}).limit(20);
 
peopleOlderThan21.observe(function(observer) {
    
    //the filtered items - max = 20
    console.log(observer.source);
 
    observer.on("insert", function(items) {
        //craig - source is also updated
    });
 
    //called when something big changes, such as limit, or skip
    observer.on("reset", function() {
 
    });
 
});
 
 
//insert a new user, triggers listener above
people.insert({
    name: "Sarah",
    age: 22
})
