You can use environment variables in npm scripts by defining them before the command. For example: VAR=value npm run script.

What if I want to use a variable in a script defined in my package.json?

You can reference environment variables in your scripts using process.env.VAR_NAME. For example: `"start": "node app.js --port=$PORT".

Are there any differences between using variables in Windows and Unix-based systems?

Yes, in Windows, you typically use set VAR=value before the command, while in Unix-based systems, you can directly define it as VAR=value.

Can I use cross-env to handle this more easily?

Absolutely! cross-env allows you to set environment variables across platforms. You can install it and use it like this: cross-env VAR=value npm run script.
