How do I build js and css without random number?

Is there a way I can build production css and js file without the random generated number at the file?

For example, every time I build I get something like this main.a31171f1.css and main.a31171f1.js. I need this because I want to be able to fix that in my index.html.

Thanks.

@noppanit Just for posterity, my build looks like this

"build": "react-scripts build && npm run build:clean",
"build:clean": "cd build && mv static/js/*.js main.js && mv static/css/*.css main.css && rm -r static",

When you run build, a file called asset-manifest.json (if I recall correctly) appears in the build folder. It contains the list of all files. You can read it in a post build step and then do anything you like (such as use that info for rewriting Chrome extension manifest).

Hope this helps.
