A comprehensive reference with 42 rules across 8 categories for optimizing Expo React Native apps, from startup time to list rendering to animation performance. The priorities are well organized: critical stuff like enabling Hermes and switching to FlashList comes first, then re-render optimization and animation best practices, down to platform-specific tweaks. Each rule links to its own reference file with examples. The structure is opinionated in a good way, basically giving you a checklist for code review or refactoring. If you're building production Expo apps and hitting performance issues, this gives you a systematic way to find the actual problems instead of randomly memoizing everything.
