How do I reduce bundle size when shipping react native components?

Asked on Oct 16, 2025

Answer

Reducing the bundle size in React Native is crucial for improving app performance and load times. This can be achieved by optimizing your JavaScript code, using efficient libraries, and leveraging React Native's built-in tools.

Use the react-native bundle command with the --minify flag to create a minified bundle.
Analyze your bundle using tools like source-map-explorer to identify large dependencies.
Replace large libraries with lighter alternatives or remove unused dependencies.
Implement lazy loading for components that are not immediately needed.
Utilize Hermes, a JavaScript engine optimized for React Native, to improve performance and reduce bundle size.

Additional Comment:

Consider using tree shaking to eliminate dead code and reduce bundle size.
Regularly update your dependencies to benefit from optimizations and bug fixes.
Profile your app to identify performance bottlenecks related to bundle size.
Use platform-specific code splitting to avoid bundling unnecessary platform code.
