Example Mongoose Connection:
//to remove warning:
/*(node:16564) DeprecationWarning: Mongoose: mpromise (mongoose's default promise library) is deprecated, plug in your own promise library
instead: http://mongoosejs.com/docs/promises.html */
mongoose.Promise = global.Promise;
//Mongodb Connection
mongoose.connect(config.database, { useMongoClient: true });
// On Connection
mongoose.connection.on('connected', () => {
console.log('Connected to database '+config.database);
});
// On Error
mongoose.connection.on('error', (err) => {
console.log('Database error: '+err);
});
