MongoLab recommended mongoose connection options. More supported connections for the underlying Node Native driver can be found here:
// mongoose 4.3.x
var mongoose = require('mongoose');
* Mongoose by default sets the auto_reconnect option to true.
* We recommend setting socket options at both the server and replica set level.
* We recommend a 30 second connection timeout because it allows for
* plenty of time in most operating environments.
var options = { server: { socketOptions: { keepAlive: 1, connectTimeoutMS: 30000 } },
replset: { socketOptions: { keepAlive: 1, connectTimeoutMS : 30000 } } };
var mongodbUri = 'mongodb://user:pass@host:port/db';
mongoose.connect(mongodbUri, options);
var conn = mongoose.connection;
conn.on('error', console.error.bind(console, 'connection error:'));
conn.once('open', function() {
// Wait for the database connection to establish, then start the app.
