Expo

A comprehensive performance optimization reference for Expo React Native with 54 rules across 9 categories, from launch time and bundle size down to memory management. Each rule includes priority ratings and specific prefixes for quick lookup. The structure is solid: you get concrete patterns like using FlashList over FlatList, enabling Hermes, avoiding barrel file imports, and leveraging Reanimated for UI thread animations. What makes this useful is the priority system. It steers you toward critical wins first (launch time, bundle size) before you waste time on micro-optimizations. The rules reference detailed markdown files with code examples, so you're not just getting a checklist but actual implementation guidance when you need it.
