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.
