A glance at what we covered during this week’s stream: nuqs 2.5, Remix v3, Expo Launch, SPM support, the Jest RFC, and native speech features with Mike Grabowski.

What we covered

  • Nuqs 2.5 in action
    • Saw how easy it is to keep state in search params.
    • Demoed it live, and wow, we were so impressed we didn’t get to the updates like debounce, schemas, key isolation, and type-safe routing.
  • Remix vs. App Router, React Router & Expo Router: We compared their approaches, strengths, and where each one shines.
  • Web Workers vs. Worklets: A short dive into how they’re alike, and why web workers are becoming a smart move for performance-focused devs.
  • Expo launch: Expo just launched a cool new initiative that streamlines app release workflows. No DevOps headache required, just build and ship like a pro.
  • SPM support & why pre-compilation wasn’t in React Native: We chatted about Swift Package Manager support and tackled the big question: why didn’t React Native include pre-compilation from day one? Mike jumped in with insights from a decade in the game.
  • Jest Split RFC & the Vite Sweepstakes: Separating Jest from RN core? Smart. Naturally, we couldn’t help but gush about Vite, too.
  • Text-to-Speech & Speech-to-Text with React Native AI: We wrapped with a deep dive into native voice features, Mike’s building it, and it’s worth watching.
