mongodb-promisified

A promisified MongoDB driver for ES6

The library wraps the 2.0.x driver with promises allowing you to access most of the functionality of the 2.0.x driver using your favorite Promise library.

Using the library

var co = require('co')
  , MongoClient = require('mongodb-promisified')().MongoClient;
 
co(function*() {
  // Connect to the database
  var client = yield MongoClient.connect('mongodb://localhost:27017/db');
  // Insert a document
  var result = yield client.collection('test1').insertOne({a:1});
  // Get the documents
  var docs = yield client.collection('test1').find({}).toArray();
  // Close the connection
  yield client.close();
}).catch(function(err) {
  console.log(err.stack);
});

Pretty straightforward to use the library with the generator library co and ES6. To use your favorite Promise library simply do the following when requiring the module.

var co = require('co')
  , Promise = require('bluebird')
  , MongoClient = require('mongodb-promisified')(Promise).MongoClient;
