`li` is a lightweight JavaScript library that parses and serializes HTTP Link headers compliant with RFC 5988. It provides simple `parse` and `stringify` functions for turning header strings into objects (and vice‑versa), making it useful for developers building API clients or servers that need to handle pagination, relationships, or other link‑based metadata. The package works in Node, browsers, and with module loaders such as Browserify, AMD, or Bower.
