Promise-based HTTP requests use async methods like GET, POST, PUT, and DELETE to communicate with REST APIs. This approach standardizes responses and reduces boilerplate across browser and Node.js environments using clean async workflows.

Interceptors allow you to intercept HTTP requests and responses to inject custom logic like authentication tokens, logging, and error handling. This mechanism modifies the request or response pipeline globally before the data is sent or processed by the application.

TypeScript is supported for HTTP request handling in both Node.js and browser environments. It provides typings and generic response handling to ensure type safety and consistency when defining request configurations and parsing API responses.

Custom HTTP instances are configured by setting a baseURL, timeout, and default headers. This creates a consistent configuration object for all outgoing requests, ensuring standard headers and base paths are automatically applied across your application.

Error handling for promise-based HTTP clients utilizes request and response interceptors to catch and process network or server errors uniformly. This standardizes error management across API calls, allowing consistent retry patterns and centralized failure logging.

Using a promise-based HTTP client for REST API calls provides built-in interceptors, configurable instances with base URLs, and standardized error handling. These features reduce boilerplate and simplify complex request pipelines compared to native fetch implementations.
