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.

Great breakdown of common agentic flows implemented with Vercel AI SDK!
AI Agents' workflows are not that hard to implement.
@q1w1n.bsky.social's article proves it and gives you examples to play with!

After reading an article from Anthropic I really wanted to implement workflows they described.
I also wanted to share the results in that article! ☺️

You know it's a good rewrite coming up! AI space is pretty interesting.
Everyone's building AI agents and AI agent frameworks right now. So many different approaches. Everything changes each week.
Decided to focus on building some production workflows, hopefully this is the last one 😂

Excited to be back on the React Universe On Air! Memories are back! I love going live, streaming, and being in front of the camera, so hopefully we can get some more content this year!
We're thrilled to welcome back @grabbou.com as host and the return of At Scale series! This time, we're diving deep with Mustafa Ali, Director of Engineering at Shopify, to explore to discuss the ins and outs of their migration to React Native.
