HTTP Content Negotiation

Negotiator is a lightweight, standalone utility for parsing and evaluating HTTP `Accept`, `Accept-Language`, `Accept-Encoding`, and `Accept-Charset` headers. It allows servers to determine the client's preferred content based on quality values (`q-factors`) specified in these headers. Primarily maintained by the `jshttp` organization, it serves as a core component for web frameworks like Express.js by abstracting complex RFC specifications for content negotiation. The current stable version is `1.0.0`. The package operates in a maintenance mode, with infrequent but significant major releases that often include breaking changes to align with evolving Node.js environments and best practices. It distinguishes itself by providing a robust and dependency-free solution for this specific HTTP concern.
