node.js - How to set useMongoClient (Mongoose 4.11.0)?

Question

This is the code I use to connect to my database:

private connectDatabase(databaseUri: string): Promise<Mongoose.Connection> {
    return Mongoose.connect(databaseUri).then(() => {
        debug('Connected to MongoDB at %O', databaseUri);
        return Mongoose.connection;
    });
}

Today I updated Mongoose to version 4.11.0 and I got this warning when running my tests:

(node:4138) DeprecationWarning: `open()` is deprecated in mongoose >= 4.11.0,
use `openUri()` instead, or set the `useMongoClient` option if using `connect()`
or `createConnection()`

I can't find any information on how to "set useMongoClient".

Do you guys know how to?

This is how you use useMongoClient:

mongoose.connect('mongodb://localhost/advisorDemoTestDB', { useMongoClient: true })
