Node.js mongodb driver async/await queries

by

Since all answers are missing some bits (catch blocks, checking that client is not null) I came with my own solution. Tested with Mongo server v4.0.7 and Node JS driver 3.2.2.

Note that the example is a console program, where we close the connection to the server in the finally block. In a web application, the connections are reused.
See Node Mongo docs. Also, the errors are logged with libraries such as Winston or Morgan and not console logged.

const MongoClient = require('mongodb').MongoClient;

const url="mongodb://localhost:27017";

async function findOne() {

    const client = await MongoClient.connect(url, { useNewUrlParser: true })
        .catch(err => { console.log(err); });

    if (!client) {
        return;
    }

    try {

        const db = client.db("testdb");

        let collection = db.collection('cars');

        let query = { name: 'Volkswagen' }

        let res = await collection.findOne(query);

        console.log(res);

    } catch (err) {

        console.log(err);
    } finally {

        client.close();
    }
}

await findOne();
