How To Generate Sourcemaps In Create React App?

I'm wondering how to generate source maps in create-react-app? are they done implicitly? and do they live in the build folder

I've read quite a lot about them being generated with webpack but my app is not using it, so I was wondering how I do this without webpack?

I also don't want to eject

According to CRA documentation, source maps are generated by default in production mode.

However, you can disable this behavior (generating source maps in production mode) by running GENERATE_SOURCEMAP=false ./node_modules/.bin/react-scripts build or if you want this behavior to be permanent, do one of the following solutions:

  1. Set GENERATE_SOURCEMAP=false in your .env file.
  2. Modify the scripts in your package.json and replace "build": "react-scripts build" with "build": "GENERATE_SOURCEMAP=false react-scripts build"
