Wait for mongo connection

[fzaffarana]

I realized that the mongoose connect is an async function.

Because that, it's possible that the server start without a established mongo connection. (I could generate errors).

I think in something like that:

exports.connect = async () => {
  await mongoose
    .connect(mongo.uri, {
      useCreateIndex: true,
      keepAlive: 1,
      useNewUrlParser: true,
      useUnifiedTopology: true,
      useFindAndModify: false,
    })
    .then(() => console.log('mongoDB connected...'));
  return mongoose.connection;
};

Or just return mongoose.connect as a promise without then, and await for the resolution of the promise on the other side.

What do you think about that?

I think we can just return the value of mongoose.connect, and await it inside a async function (that can be called main or something like this) in https://github.com/danielfsousa/express-rest-es2017-boilerplate/blob/master/src/index.js#L9

This will be fixed on version 2 #334
