Why Frontend Needs Clean Architecture
React component files often become bloated monoliths combining API calls, state management, business transformations, and JSX markup. This impairs unit testing and increases regression risks when backend endpoints change.
Three Core Layers of Clean Architecture
- Domain Layer (Entities & Use Cases): Pure business rules independent of React or any UI framework.
- Data Layer (Repositories & Adapters): Responsible for fetching data from REST APIs, GraphQL, or Firestore.
- Presentation Layer (Components & Custom Hooks): UI elements displaying data and handling user actions.
Conclusion
Clean Architecture isolates core business logic from framework lock-in, making web applications testable, modular, and resilient to change.
