import { MongoClient } from 'mongodb';
const client = new MongoClient(process.env.MONGODB_URI);
const db = client.db('test');
assert(db.client === client); // returns the MongoClient associated with the Db object

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
