How can I use cross-env for advanced environment variable management?

You can use cross-env to set environment variables in a cross-platform way. What specific use case do you have in mind?

I want to set different variables for development and production environments.

You can create scripts in your package.json like this: "scripts": { "start": "cross-env NODE_ENV=production node app.js", "dev": "cross-env NODE_ENV=development node app.js" }.

Can I use it with other tools like webpack?

Absolutely! You can integrate cross-env with webpack by setting environment variables in your webpack configuration.

What if I need to pass multiple variables?

You can chain them together like this: cross-env VAR1=value1 VAR2=value2 node app.js.
