How to Structure API Architecture in React: Service Layers and Interceptors

As React applications scale, placing API logic directly inside components leads to tightly coupled, hard-to-maintain codebases. A layered architecture separating components, custom hooks, service layers, and a central API client addresses this problem by assigning clear responsibilities to each level. Tools like Axios offer built-in interceptors that enable centralized handling of authentication tokens, error responses, and request logging without repeating code across components. Axios and the native Fetch API both remain valid choices, with the decision depending on team needs and project requirements. This approach ensures React components stay focused on UI rendering while backend communication logic remains modular and reusable.
