Building Scalable React Apps with Clean Architecture

When building large-scale React applications, architecture decisions made early can either accelerate or cripple your team’s productivity. This guide covers proven patterns for structuring React apps that remain maintainable as they grow.

Feature-Based Folder Structure

Instead of organizing files by type (components, hooks, utils), organize them by feature. Each feature folder is self-contained and includes its own components, hooks, and API calls.

Separation of Concerns

Keep your UI components dumb — they should only render data passed via props. Business logic lives in custom hooks, and data fetching is handled by a dedicated layer.

State Management Strategy

Not everything needs global state. Use React Query for server state, Zustand or Context for UI state, and keep component state local when possible.
