self-contained mongodb implementation

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
})
