react-native-best-practices

Performance optimization guide for React Native applications, covering JavaScript/React, Native (iOS/Android), and bundling optimizations. Based on Callstack's "Ultimate Guide to React Native Optimization". Each reference file follows a hybrid format for fast lookup and deep understanding: Impact ratings : CRITICAL (fix immediately), HIGH (significant improvement), MEDIUM (worthwhile optimization) Reference these guidelines when: Follow this cycle for any performance issue: Measure → Optimize → Re-measure → Validate If metrics did not improve, revert and try the next suggested fix. Profile first: Common fixes: Analyze bundle: Verify improvement after optimization: Common fixes: Measure TTI: Common fixes: Profile native: Common fixes: Full documentation with code examples in references/ : Based on "The Ultimate Guide to React Native Optimization" by Callstack. - Quick Pattern : Incorrect/Correct code snippets for immediate pattern matching - Quick Command : Shell commands for process/measurement skills - Quick Config : Configuration snippets for setup-focused skills - Quick Reference : Summary tables for conceptual skills - Deep Dive : Full context with When to Use, Prerequisites, Step-by-Step, Common Pitfalls - Debugging slow/janky UI or animations - Investigating memory leaks (JS or native) - Optimizing app startup time (TTI) - Reducing bundle or app size - Writing native...
