Hi, Interesting code, learnt quite a lot from it.

Ideas:

  1. Your .env file isn’t hidden,
    I can see your credentials and connect to the cluster if wanted.
    [ It’s not terrible because Atlas has a lot of restrictions, but it would be easy to wipe out your databases ]

  2. Did you test your connection?
    This is how I tested:

First, comment out your main function, and write a simplified one:

async function main() {
    const URI = process.env.MONGO_URI;// Declare MONGO_URI in your .env file
    const client = new MongoClient(URI, { useNewUrlParser: true, useUnifiedTopology: true });
    const a = await client.connect()
    return a
}
main().then(client=>console.log(client)).catch(e=>console.log(e))

Now run node connection.js

You will find the first bug, I believe.

@dagim The reason why the REPL.it env file is not hidden, is because you place it in a subfolder. It has to be in the top level.
