HTTP Authorization Utilities

The `http-auth-utils` library provides synchronous, pure functions designed for parsing and building HTTP `WWW-Authenticate` and `Authorization` headers according to relevant HTTP RFCs. As of its current stable version, 7.0.1, it requires Node.js >= 24.14.0, signifying its alignment with modern JavaScript environments and practices, likely including ESM-first distribution. While a specific release cadence isn't mentioned, major version bumps suggest regular and significant updates. The library is framework-agnostic, suitable for both server and client-side JavaScript/TypeScript applications. Its key differentiators include a pure functional design without side effects, synchronous operations optimized for small header sizes, and explicit extensibility, allowing developers to integrate custom authentication schemes beyond the built-in support for Basic, Digest, and Bearer. This offers a lightweight, focused solution for HTTP header manipulation without the overhead of full-fledged authentication systems.
