Kim Chouard – Zero to Music Hero: Building Cross-Platform Games in Months With React Native & Skia
Summary
TLDRIn this insightful presentation, Kimar, the CTO of ODS Music, challenges the notion that React Native is slow and unsuitable for web development. He demonstrates how a single code base can be used to build high-performing apps for both native and web platforms, using the example of ODS Play, a multiplatform music learning game. He discusses overcoming performance challenges, leveraging Reanimated and Skia for smooth animations, and optimizing UI with platform-specific styles. Kimar also addresses the importance of minimizing re-renders and using tools like Storybook for UI testing, concluding with a call for collaboration on improving audio capabilities in React Native.
Takeaways
- 🚀 The speaker aims to change the narrative around React Native's performance, arguing it can be as performant as native code with a single code base for both native and web platforms.
- 🎼 Kimar, the CTO of ODS Music, shares their experience building a multiplatform music learning game, ODS Play, which faced specific performance challenges due to its real-time feedback nature.
- 🎮 The game requires a 60 FPS frame rate with no lag to maintain tempo accuracy, emphasizing the need for high performance across web, iOS, and Android platforms.
- 🔄 React Native's single-threaded nature can lead to performance bottlenecks when handling animations and user interactions simultaneously.
- 👌 The use of 'useNativeDriver' in React Native allows offloading animations to the UI thread, freeing up the JavaScript thread and preventing thread overload.
- 🛠 Reanimated library provides more intuitive API and control over animations, keeping everything on the UI thread and enhancing performance.
- 🎨 Skia, a common rendering engine across different platforms, is utilized for efficient rendering, but requires compiling and dealing with low-level code, which is simplified by the use of React Native for Skia.
- 📏 React.memo is used to prevent unnecessary re-renders, ensuring components only update when their props change, which is crucial for performance in a game with many interactive elements.
- 🔍 The concept of 'viewport rendering' is introduced to only render notes that are currently visible to the user, improving performance by not rendering thousands of notes at once.
- 🌐 Tailwind CSS approach is mentioned for its potential in applying platform-specific styles and animations within React Native, offering a powerful way to handle styling.
- 📚 Storybook is highlighted as a tool for isolating UI components for testing and ensuring consistency across different settings and platforms.
