You know that @chmal.it is cooking 🧑‍🍳 with Rozenite. He's in Prague tomorrow doing a deep dive into React Native DevTools. Ever wondered how they actually work? He reverse-engineered the whole thing and built a plugin framework around it.

bittersweet news: today is my last day at Bluesky. 💙 i’m very thankful to the team for letting me learn many new things on the job (including React Native). i’m wishing them luck in the improbable — but inevitable — task of making decentralized social media usable and competitive.

Microfrontends for mobile? It always felt like an R&D project—until now. With Re.Pack & Zephyr Cloud, you can actually deploy them today. On React Universe On Air, I spoke with Zack Chapple & @jbroma.dev about what makes this possible & how it changes mobile dev. 🎧 Listen here: hubs.li/Q034sJZt0

Meet Fabrice AI - functional framework for building AI agents. While building Cali, I needed something stateless that can work on the server, inside CLI, breakdown complex tasks, and be simple. Couldn't find one, so I built one. Give it a try! github.com/callstackinc...
