Mongoose Connect Using Async/Await

Mongoose has two ways of connecting to a MongoDB database, connect() and createConnection(). You can use these within an async function as follows:

// Connect to a MongoDB server running on 'localhost:27017' and use the
// 'test' database.
await mongoose.connect('mongodb://localhost:27017/test', {
  useNewUrlParser: true // Boilerplate for Mongoose 5.x
});

and for createConnection()

// Connect to a MongoDB server running on 'localhost:27017' and use the
// 'test' database.
await mongoose.createConnection('mongodb://localhost:27017/test', {
  useNewUrlParser: true
});
