Is there a way to render HTML/CSS/JS in /public/index.html on build?

[dmitrizzle]

• At minimum, I'm looking for a way to import CSS into index.html that could be rendered on build (i.e. sanitize.css from NPM or https://github.com/KyleAMathews/typefaces CSS package). Is there a way to do this and have it minified on build?
• Is there a way to do the same with JavaScript AND have it run through Babel so that it's baked into HTML?

Thank you!

Should anyone else wonder, I built my own precompile.js that modifies HTML as-needed and added it in package.json's scripts object like so: "start": "node precompile && react-scripts start". Done the same for the build step as well. Seeing how this isn't related to CRA after all, I'm gonna close this. Thanks!
