SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill provides comprehensive guidelines and tools to significantly improve the performance of React Native applications, addressing issues like slow UI, jank, large bundle sizes, and memory leaks.

Core Features & Use Cases

  • Performance Auditing: Identify bottlenecks in JavaScript, native code, and bundle size.
  • Optimization Strategies: Apply best practices for rendering, animations, startup time, and memory management.
  • Use Case: Debugging a React Native app that feels sluggish during scrolling and has a slow startup time by applying the recommended optimizations for lists and TTI.

Quick Start

Use the react-native-best-practices skill to analyze and optimize the performance of a React Native application.

Frequently Asked Questions about react-native-best-practices

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I fix React Native frame drops and UI jank during scrolling?▼

Fix React Native jank by identifying JavaScript thread blocking and bridge overhead. Optimize scrolling performance by replacing standard lists with FlashList and applying rendering best practices to eliminate frame drops.

What's the best way to reduce React Native startup time and TTI?▼

Reduce React Native startup time and TTI by optimizing Hermes engine usage and minimizing bundle size. Apply specific performance guidelines to improve application responsiveness and ensure faster initial load times.

How do I profile and debug memory leaks in a React Native app?▼

Debug memory leaks in React Native through performance profiling to identify bottlenecks in JavaScript and native code. Apply memory management best practices to resolve leaks and improve overall application efficiency.

Does this approach work for optimizing React Native animations and re-renders?▼

Yes, React Native optimization covers animations and re-renders by addressing JS thread blocking and bridge overhead. Implement actionable steps to smooth out animations and prevent unnecessary component re-rendering.

Can I use these optimization guidelines with native modules and Hermes?▼

Yes, these guidelines apply directly to native modules and Hermes optimization. They provide actionable steps to reduce bridge overhead and improve JavaScript execution efficiency for better mobile app performance.

Why does my React Native app have a large bundle size and slow performance?▼

A large React Native bundle size causes slow performance by increasing TTI. Audit bottlenecks in your JavaScript and native code, then apply optimization strategies to reduce bundle size and improve app responsiveness.
