I can see you do have "start" script in your package.json

  "scripts": {
    "start": "react-scripts start", <--- here
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },

react-scripts is a set of scripts from the create-react-app starter pack.

You need to run npm start command in your terminal in order to run the app.

In common apps, the start script looks like so:

"start": "npx node index.js"

Where index.js can be also the server.js file
