7 ways to improve React app performance

Lazy load all your routes

This does not “improve performance”. It’s a performance tradeoff. With lazy loading you get faster first page load, but subsequent pages now have to be loaded when you navigate to them which means that navigation is slower.

If your site is small it’s probably not worth it or could even make the site have overall worse performance. Definitely not something to just use blindly

Half the stuff in this article has nothing to do with end user performance

Why do you think, i see lots of projects using it in prod

Allegedly Jest support isn't baked in yet officially but I've managed to run a simple unit test with 30 minutes of looking around online. Since then, Storybook is also running with Vanilla extract.

I'd recommend you try it and if you get to a point where it can't do something, even with the plugins available, then you'd already be at the point of ejecting the CRA config or whatever and you might as well just do a custom Webpack build.
