Notes

• now you can use webpack.config.mjs and webpack.config.js with { "type": "module" } in package.json
• you can avoid using the cross-env package:

Before:

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

Now (you can remove the cross-env if you don't use it somewhere else):

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

• the mode option respect the --node-env option if you don't set the mode option explicit using CLI options or in configuration(s), i.e. --node-env production set process.env.NODE_ENV and mode to production
