callback aproach

const uri = '...'
iotMongo.connect(uri, (err, _db) => {
    if (err) console.error(err);

    // now you can use the database
    iotMongo.collection('').find({}).toArray((_err, data) => {
        console.log(data);
    });
})

promise aproach

const uri = '...';
try {
    await iotMongo.connectPromise();
    // now you can use the database
    const data = await iotMongo.collection('').find({}).toArray();
    console.log(data);
} catch (error) {
    console.error(error);
}

connect to external database

iotMongo.connectToExternal('uri to external db', (err, client) => {
    if (err) console.error(err);

    // now you can use the database
    client.db('my-db').collection('my-coll').find({}).toArray((_err, data) => {
        console.log(data);
    });
});
