is there a mongoose connect error callback
there many mongoose callback you can use,
// CONNECTION EVENTS
// When successfully connected
mongoose.connection.on('connected', function () {
console.log('Mongoose default connection open to ' + dbURI);
});
// If the connection throws an error
mongoose.connection.on('error',function (err) {
console.log('Mongoose default connection error: ' + err);
});
// When the connection is disconnected
mongoose.connection.on('disconnected', function () {
console.log('Mongoose default connection disconnected');
});
// If the Node process ends, close the Mongoose connection
process.on('SIGINT', function() {
mongoose.connection.close(function () {
console.log('Mongoose default connection disconnected through app termination');
process.exit(0);
});
});

When you connect you can pick up the error in the callback:
mongoose.connect('mongodb://localhost/dbname', function(err) {
if (err) throw err;
});
In case anyone happens upon this, the version of Mongoose I'm running (3.4) works as stated in the question. So the following can return an error.
connection.on('error', function (err) { ... });
