How to run dev and build together?

Question

Node.js

Good afternoon, there was a need for automatic production generation during development. How to run a command like "super": "dev && build" ?

"scripts": {
    "dev": "webpack-dev-server --mode development --open",
    "build": "webpack --mode production"
  },

Answer 1

On Windows like this:
(npm run dev) && (npm run build)

Answer 2

If in linux: npm dev && npm build
But, in general, logically, you need to run the build first, and then the dev.
