npm parallel execution of commands not working

Question

I have a package.json file at the root of my project folder which contains client and server folders. in the root package.json I have the following scripts:

"scripts": {
    "server": "npm run watch --prefix server",
    "client": "npm start --prefix client",
    "watch": "npm run server & npm run client"
  }

but when i try to run npm run watch only the server script runs, what I don't understand is if I paste the contents of the watch script into the terminal it works just fine.

Does this answer your question? [How can I run multiple npm scripts in parallel?](https://stackoverflow.com/questions/30950032/how-can-i-run-multiple-npm-scripts-in-parallel) — evolutionxbox, Jul 22 '22 at 13:43
@evolutionxbox the problem is If I paste the command in the `watch` script into the terminal it works, but when I do `npm run watch` it does not work (it only starts the `server`). — TrojanMouse, Jul 22 '22 at 16:20

npm run <script> uses cmd.exe by default if you are on windows, and cmd does not support & to run commands in parallel, so it is better to use a package like npm-run-all.
