You can add this snippet before starting mongoDB to see what's getting to your node process env variables:

console.log(process.env)

Also note that you can pass inline environment variables to node process like this:

PORT=4000 node ./my-script.js

To automatically load .env files, you might be using this package: https://github.com/motdotla/dotenv so be sure that you have all packages installed (npm install or yarn install, depending on what you are using).

it works !! but only with npm start /// with nodemon I still get undefined for the env variables. (logged them to the console and I got undefined) I think the trouble with nodemon here

One of the first things you should pay attention to is the file path. Check where your .env file is located in the project. If it is in the root of the project, there is no need to do anything. Otherwise, you must specify the path to the .env file.
