I am following a node course and while setting the environment variable as shown it does not work

It says to set environment variables, use SET on Windows and EXPORT on Mac:

set jwtkey=myprivatekey, when I use this nothing happens, it does not set anything.

This is set using the config package, and I have also created a separate files for default.json and custom-env.json

if (!config.get("jwtPrivateKey")) {
    console.error("FATAL ERROR: JwtKey Not Set");
    process.exit(1);
}

please help

this is my .env file(using dotenv)

PORT=9000 //this is working
jwtPrivateKey="myPrivateKey" //this is not working tho.

[basically, I wanted to hide my VERIFY SIGNATURE(digital signature) and store it in ENV so that it cant be accessed.]

I would do it differently.

1. Create a .env file in your server root.

2. Add the key/value pair:

   JWT_PRIVATE_KEY="936392a8c..."
   

3. Install dotenv, and import it.

4. Access process.env.JWT_PRIVATE_KEY from anywhere in your server app.

(based on this article.)

If you use set in a Windows terminal, it will set the variable just for this terminal. If you start the node in the same terminal, everything should work fine. Otherwise read this article on how to change the variable permanently.

There are two types of environment variables in Windows: user and system variables. If possible, use a user variable.
