To centralize API calls in Next.js, create a single entry point like src/lib/api.ts. This module standardizes HTTP requests, enforces typed request and response models, and manages shared configuration for API_BASE_URL across server and client components.

The best way to handle API errors consistently is to implement centralized error handling within your API client layer. This approach uses a uniform ApiError model to standardize error parsing and response management across all server and client HTTP calls.

You can manage authentication headers in Next.js 16+ by using a centralized API client module. This client provides unified auth header management, ensuring that secure credentials are consistently applied to all outgoing HTTP requests.

Yes, a centralized API client is designed for both server and client components in Next.js App Router. It provides clear separation of concerns and usage guidance, ensuring typed HTTP calls work correctly across different rendering environments.

To add strong typing to HTTP requests in Next.js, define TypeScript interfaces for your expected payloads and responses within a centralized API client layer. This enforces type safety across all REST/JSON backend communications.

Using a single entry point to fetch data from a REST backend in Next.js reduces code duplication, improves TypeScript typing, and standardizes error handling. It ensures consistent API_BASE_URL configuration and auth header management.
