Hi everyone!
This week I’m excited about a promising new headless component library, and I’ve found various interesting articles about Web Components relevant to React developers.
On the mobile side, Google introduced Android XR and React Native support is already coming!
🎄 We are taking a Christmas break, this is the last newsletter until 8th January.
🧑🎄 You’ve already given me a great gift, we are now 4th most popular JS newsletter according to the recently published State of JS 2024 survey result.

⚛️ React
I’m usually not into UI libs. But when Radix, MUI and Floating UI creators gather to create a new set of 25 unstyled, accessible, composable primitive components with great care to details, I think it’s worth paying attention! Radix is super popular these days (notably thanks to shadcn/ui), but has been less actively maintained recently, and a new headless lib challenger is always welcome!
React 19 and Custom Elements
Various related articles I found interesting:
📜 React 19 and Web Component Examples: Chris Coyier testing React 19 custom elements support by creating a Lit element and rendering it though JSX. You can seamlessly pass an object as props, but for event handlers you may need to dispatch a custom event.
