Feature-Based Folder Structure for Scalable React Native Apps

Insight

Instead of the classic "screens/, components/, utils/" layout, group files by feature (e.g., profile/, checkout/). Each feature folder contains its own UI, hooks, types, and tests. This reduces the cognitive load when navigating a large codebase and isolates changes, so teammates rarely step on each other's toes during PR reviews.

Example

src/
├─ profile/
│  ├─ ProfileScreen.tsx
│  ├─ useProfile.ts
│  ├─ profileSlice.ts
│  └─ index.ts
├─ checkout/
│  ├─ CheckoutScreen.tsx
│  ├─ useCart.ts
│  ├─ checkoutSlice.ts
│  └─ index.ts
└─ shared/
   └─ Button.tsx

// src/profile/index.ts
export { default as ProfileScreen } from './ProfileScreen';
export * from './useProfile';
export * from './profileSlice';

Takeaway

Adopt a feature‑first folder hierarchy early; it scales with your app, keeps related code together, and makes refactoring or extracting a feature into a separate package much simpler.
