api-client-patterns

Use a standardized axios instance with centralized configuration, request and response interceptors, and retry logic to build an HTTP client with consistent error handling that ensures reliable API calls across web applications and microservices.

Manage API configuration across multiple microservices by centralizing base URLs, timeouts, and headers in a reusable axios instance, ensuring predictable error semantics and consistent behavior across all service integrations.

Axios interceptors intercept outgoing requests and incoming responses to inject authentication tokens, execute logging operations, and apply consistent error transformation before the response reaches the application, ensuring reliable API calls.

You can implement cancellation and streaming support for long-running API calls using these axios client patterns, which specify optional streaming capabilities and cancellation support to manage sustained HTTP connections and prevent hanging requests.

This API client pattern works for both frontend and backend services needing reliable API calls, applying standardized configuration, type safety, interceptors, and error transformation across web applications and microservices to ensure consistent integrations.

Your HTTP client needs centralized error transformation to eliminate repeated boilerplate and inconsistent error handling across APIs, providing predictable error semantics for frontend and backend integrations while preventing fragile application logic.
