Meta Tech Podcast

It’s not just Not Invented Here Syndrome. Some technologies like CSS simply don’t scale if you’re building some of the largest websites on the planet with thousands of engineers committing to the same code base every day. StyleX is Meta’s open-source solution for CSS at scale and allows atomic styling of components while deduplicating definitions for bundle size and exposing a delightfully simple API for developers.
Tune in to learn from Melissa, one of the StyleX maintainers how Open Source has acted as a force multiplier for the project, how interacting with other large companies adopting StyleX has been, and much more!
