I'm working on a small application and I need to automatically add a timestamp of creating/updating my documents in the default Nodejs MongoDb driver. Right now, when I add a new document, it only has added the _id field. Is there a way to force the addition of the createdAt/updatedAt fields?

Drivers do not generally provide this functionality. ODMs do. In case of Node, mongoose is an ODM which does.

You can add createdAt manually when creating the object this way:

        await this.collection.insertOne({ businessAuth: _id, url, labels, createdAt: new Date()});

And updatedAT when updating the object this way:

video.updatedAt = new Date();
const saved = await this.collection.findOneAndUpdate({_id: video._id}, {$set: {...video}});
