How to generate sourcemaps in create react app?
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:
- Set GENERATE_SOURCEMAP=false in your .env file.
- Modify the scripts in your package.json and replace
"build": "react-scripts build"with"build": "GENERATE_SOURCEMAP=false react-scripts build"

You can truly set GENERATE_SOURCEMAP=false for windows, like @3b3ziz said. However, to run the script across different OS, its better follow the Advanced Configuration Chapter in official document.
Here's what's needed:
Create a
.envfile in the root of the project. (same folder as yourpackage.json)
Write
GENERATE_SOURCEMAP=falsein this file.Rerun whatever you need.
react-scriptsdoesn't detect change in.env.
