initilize

var Monglo = require('monglo').Monglo;
var db = Monglo('DBNAME');

DataStore

Datastores for persistence your db with local/remote data

var monglo = require('./index').Monglo;
var db = monglo('DemoDB');

//Define a store locally or import a common js module;
//See source for all available functions
function DemoStore(){
  return {
    insert : function(args){  },
    update : function(args){  },
    open   : function(args){  },
    remove : function(args){  },
       all : function(args){  }
  };
}
//Load the store in Monglo
db.use('store', new DemoStore());

find

db.someCollection.find();

insert

db.someCollection.insert({text: "Hello, world!"});

update

db.someCollection.update({name:'tester'}, {$set: {text: 'test'}});

remove

db.someCollection.remove({uid:'34245'});

Cursors

To create a cursor, use find. To access the documents in a cursor, use forEach, map, or fetch.

var someCursor = db.someCollection.find();

forEach

Call the callback function once for each matching document.

someCursor.forEach(function(doc){ console.log(doc); });

map

Map callback over all matching documents. Returns an Array.

someCursor.map(function(doc){
  doc.fullname = doc.firstname+' '+doc.lastname;
  return doc;
});

fetch

Return all matching documents as an Array.

someCursor.fetch(function(docs){ console.log(docs); });

count

Returns the number of documents that match a query.

someCursor.count();

rewind

Resets the query cursor.

someCursor.rewind();

Events

Watch a query. Receive callbacks as the result set changes.

Monglo.Collection('my_collection');
var someCollection = db.someCollection('mycollection');

//See docs for all events
someCollection.on('insert', function(){ /** Do something  **/ });
someCollection.on('update', function(){ /** Do something  **/ });
someCollection.on('remove', function(){ /** Do something  **/ });
someCollection.on('find', function(){ /** Do something  **/ });
someCollection.on('createCollection', function(){ /** Do something  **/ });
someCollection.on('removeCollection', function(){ /** Do something  **/ });
