HTTP Client Utility Module

util-http is a JavaScript and TypeScript utility library designed to simplify and standardize HTTP requests by providing a unified API layer over several popular underlying HTTP clients. It currently supports wrapping `Axios`, the native `Fetch API`, `Undici` for high-performance Node.js environments, and `Superagent` for isomorphic (Node.js and browser) use cases. The library is currently in an early development phase, at version 0.0.15, implying a potentially rapid release cadence with possible breaking changes between minor versions. Its primary differentiator is the ability to swap out the underlying HTTP client while maintaining a consistent `ClientConfig` for global settings and `ClientOptions` for per-request overrides, complete with robust TypeScript type definitions for enhanced developer experience. It aims to abstract away client-specific configurations and error handling into a standardized interface, allowing developers to choose their preferred backend client without changing their application's request logic.
