Building

 $ npm install
 $ make

initilize

var Monglo = require('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

Find all docs that match query parameters

db.someCollection.find({}, function ( error, cursor ){ });

findOne

Find a single doc that matches query parameters

db.someCollection.findOne({}, function ( error, doc ){ });

insert

Insert a new doc

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

update

Update and existing doc

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

save

Update doc if exists if not insert the new doc

db.someCollection.save({DOC}, function ( err, doc ){ });

remove

Remove the doc matching the query selector

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

backup

Saves snapshot of collection's current state in memory Backup ID defaults to a new ObjectId string if non is provided

db.someCollection.backup('backuId_1234', function (err) { });

restore

Restore the state of a collection from backup

db.someCollection.restore('backuId_1234', function (err) { });

backups

Lists available Backups

db.someCollection.backups(function (err) { });

removeBackup

Remove a backup from memory. If backup id is left empty all backups will be removed;

db.someCollection.removeBackup('backuId_1234', function (err) { });

Cursors

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

db.someCollection.find({}, function (err, cursor) {
  // Cursor instance for query
});

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  **/ });
