How to disable source maps for React JS Application

Question

My react folder structure is as below

I've not 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 cannot work in removing 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"   }
