?? Reduce App Build Size in React-Native Projects

Optimizing the build size of your React Native app is essential to ensure swift loading and minimal storage consumption on users' devices. Below are various strategies and tips to assist you in minimizing the build size of your React Native application:

??? Fine-tune Third-party Libraries:

• Make Thoughtful Selections: Opt for lightweight libraries and trim(Remove) unnecessary dependencies from your `package.json` file.

??? Optimize Fonts:

• Minimize Custom Fonts: Font files occupy significant space, contributing to increased app build size. By reducing custom font files, you can effectively save space. Consider utilizing minimal custom fonts.
• Utilize System Fonts or Limit Font Families: Whenever possible, use system fonts to further optimize the build size. Alternatively, limit the number of font families to one or two for efficient font management.

? Code Splitting and Lazy Loading

• Lazy Loading: Implement lazy loading with React.lazy() and dynamic imports for heavy modules.
• Code Splitting: Use tools like React Loadable or React Native Bundle Splitter for smaller, on-demand code chunks.

??? Optimize Image assets

• Local Images: ? Keep a minimal number of images within the codebase. ? Opt for optimized image file formats like WebP, PNG, and SVG for efficient storage.
• Server Images: Enhance performance by incorporating image caching libraries such as Fast Image, etc. This ensures smoother handling and faster loading of server-sourced images.

?? Native side Code Optimizations:

• Enable R8 Optimization
• use Proguards
• Enable minifyEnabled flag

?? Optimal Upload on Play Console:

• Choose Bundle File over APK: When uploading files to the Play Console, opting for a bundle file provides a distinct advantage over an APK file. The bundle file encompasses consolidated code for all architectures. However, by uploading a bundle file, the server(Play Store) delivers only the architecture-specific code, omitting unnecessary code for other architectures. This results in a more streamlined and efficient download.
