I'm a big fan of Firebase Firestore when it comes to side projects.

However for this specific challenge I'd like to try out lowdb instead as it seems to be really small and nearly perfect for small servers & utilities.

Note: we're using an in-memory adapter for the purpose of this challenge, but to make sure the code being written is independent of the adapter we still await for .value() & .write() methods of the DB. This way if we were to switch away from an in-memory adapter to, say, one that utilizes the FS, we shouldn't have to change actual interactions with the DB.
