I built this React Native onboarding with react-native-tgfx ✨ A live aurora. Glass cards fold into light, then unfold into the next page. Expo + Reanimated. WebGPU + TypeGPU particles. Thanks @margelo_com , @swmansion , @expo 🙌 #expo #margelo #ReactNative #UIAnimation #NativeCook

@margelo_com's react-native-tgfx gets better every day, and my fix just got merged 🎉 Thanks @RiteshRk14 for the review After moving my drawing app from Skia to tgfx, noticed RAM kept climbing with every offscreen render, so I tracked it down and landed a fix 450 renders: +54 MiB → +2 MiB

The Mobile Dev Codex Plugin even highlights hickups in perf graphs, which are auto-fix suggestions. ✅
