Addy Osmani and Hassan Djirdeh [JSX Over the Wire](https://overreacted.io/jsx-over-the-wire/) — Dan Abramov builds on last week’s epic [React for Two Computers](https://overreacted.io/react-for-two-computers/) with thoughts on the evolution of passing data from server to client, contrasting traditional REST endpoints with a BFF approach that builds screen-specific ViewModels mirroring React’s component tree. An enjoyable train of thought for anyone interested in how and why client/server apps are organized the way they are and how it could be even better.

How fast? Very, it seems. Jonas Galvez [Creating an AI Chat Experience with React and OpenAI](https://www.robinwieruch.de/react-ai-chat/) — If you’d rather create your own streaming chat UI for OpenAI’s models (such as for the new API-only GPT 4.1 models) Robin has some pointers for getting started.

RedwoodJS [react-photo-sphere-viewer: A Component to View Photo Spheres](https://github.com/elius94/react-photo-sphere-viewer) — This is one of those cases where [a live demo](https://codesandbox.io/p/sandbox/react-photo-sphere-viewer-playground-zd8nt8) is valuable. It’s basically a way to navigate specially-taken 360 degree photos (think Google Street View - kinda).
