design-system VS vanilla-extract

This one just has a couple variants I've done, but you can add as many as you want. My dev mentor is a Senior who works on the design system at Priceline and showed me how. You can find the docs for it here: https://priceline.github.io/design-system/

For building component libraries I’ve been a big fan of vanilla extract. Apparently it’s from the same people who made css modules

This sounds exactly like Vanilla Extract. https://vanilla-extract.style/

KumaUI : Another relatively new contender, Kuma uses zero runtime CSS-in-JS to create headless UI components which allows a lot of flexibility. It was heavily inspired by other zero runtime CSS-in-JS solutions such as PandaCSS, Vanilla Extract, and Linaria, as well as by Styled System, ChakraUI, and Native Base. ### Vue

The components are styled with CSS modules. When building the library, these styles will get transformed to normal CSS style sheets. This means that the consuming application will not even be required to support CSS modules. (In the future I want to extend this tutorial to use vanilla-extract instead.)

I do a lot of UI work and have never understood the appeal of Tailwind. It’s like relearning a new language. Tailwind was released in 2017. Maybe the CSS landscape wasn’t as good back then? Modern CSS is pretty awesome.

I’ve enjoyed using Vanilla Extract https://vanilla-extract.style/. It’s like css-in-js with none of the downsides as everything gets compiled to css.

Nah, I used enough Tailwind to know it becomes a spaghetti mess. I stick with CSS now, and in React I use https://vanilla-extract.style, compile time CSS in TypeScript.

Vanilla Extract is my current choice for the next greenfield project. I would also recommend checking out how and why this team integrated it with Tailwind.

I'm not trying to call a particular org or library out, because I think the ones I've been digging through (and prompted me to write this) are very high quality. It's vanilla-extract (a build-time CSS-in-JS library) and Braid Design System (built on vanilla-extract).

Apart from what has been suggested, there is also https://vanilla-extract.style/.

To be fair, I don't like Tailwind either but styled-components is runtime CSS, Tailwind is compile time. You can achieve the same thing via CSS modules or vanilla-extract though.
