Thanks for the suggestions.

Are you using the built-in Lighthouse performance audit in Chrome?

Asking, because On My Machine™ it does not show anything about minifying JS (should be done by default in CRA npm build)

As for images - do you mean jpgs or maybe some of the new formats like WebP?

And the last thing - CSS, do you know any straight forward solution here for Create React App?
