Answer 1

Install concurrently by using npm i concurrently

then add below scripts to your backend pakage.json

This will allow you to run your backend and frontend servers at the same time.

    "start": "node server",    
    "client": "npm start --prefix client",
    "dev": "concurrently \"npm run start\" \"npm run client\"",

Then run npm run dev in backend application directory to run the application
