Building Scalable React Native Apps in 2024

Introduction

After 5+ years building production React Native applications, I've learned that architecture decisions made early can make or break a project at scale.

Key Patterns

1. Feature-based folder structure

Instead of grouping by type (components, hooks, utils), group by feature. This keeps related code together and makes it easy to delete or refactor a feature.

src/
  features/
    auth/
      components/
      hooks/
      store/
    dashboard/
      components/
      hooks/

2. Offline-first with React Query

Always assume the network will fail. Use React Query with persistent storage for a seamless offline experience.

3. Native modules wisely

Don't rush to build native modules — most functionality is covered by the community. But when you need performance-critical code (camera, sensors), invest in a proper native module.

Conclusion

The fundamentals don't change: keep it simple, test your code, and build for the user's reality.
