React Weekly #42 explores real cross-platform architecture and hard-won performance wins. Here is what is inside this issue: - Structuring Next.js and Expo domain layers - Surviving a 5M-user cutover via EAS OTA updates - Deep visual debugging with Suspense DevTools - Wasm streaming optimizations

📱 A massive release goes sideways—what do you do? The TeamReach team rolled out 12 over-the-air updates across 3 days to rescue an app migration serving 5 million active users, avoiding store approval lag entirely.

Suspense boundaries shouldn't feel like a black box. Aurora Scharff shows how to leverage the React DevTools Suspense panel to inspect suspended state, inspect pending data, and coordinate smooth UI transitions.

Speed without payload reduction: Sergey Patrakeev shaved 19% off initial load times for a 9 MB Wasm module just by reordering execution and switching to streaming compilation. No asset stripping required.
