javascript - How to set environment variables in a cross-platform way?

Question

For Windows, my Node scripts should look like this:

"scripts": {
    "start-docs": "SET NODE_ENV=development&&babel-node ./docs/Server.js"
}

But on Linux there's no SET, so it would be like this:

"scripts": {
    "start-docs": "NODE_ENV=development&&babel-node ./docs/Server.js"
}

Is there a way to declare environment variables in a way that is consistent and cross-platform?

Answer 1

I recently came across the cross-env project. It's pretty straight-forward

{
  "scripts": {
    "build": "cross-env NODE_ENV=production webpack --config build/webpack.config.js"
  }
}

That will set the build environment variable to production regardless of the OS.
