How to disable source maps for React JS Application?

Question

My react folder structure is as below:

I haven't used the create-react-app version. I tried using GENERATE_SOURCEMAP=false, but it didn't work.

Where can I find the .map files? How can I delete those files?

I cannot find a build folder. I've tried using the below script, but it can't remove source maps.

 "scripts": {

    "start": "react-scripts start",
   "build": "GENERATE_SOURCEMAP=false && npm run build",
    "test": "react-scripts test --env=jsdom",
    "eject": "react-scripts eject"
  },

Answer 1

just remove &&

"scripts": {    
    "start": "react-scripts start",
    "build": "GENERATE_SOURCEMAP=false react-scripts build",
    "test": "react-scripts test --env=jsdom",
    "eject": "react-scripts eject"
  }
