HTTP Hash Router

http-hash-router is a lightweight server-side routing utility for Node.js's native `http` module, built upon the `http-hash` package for pattern matching. It is currently at version 2.0.1 and appears to be a stable, mature package primarily designed for CommonJS environments, indicated by its `require` syntax in examples. While specific release cadence isn't published, its current version and historical usage patterns suggest a focus on stability rather than frequent feature updates. It provides a simple API to define routes using patterns (including parameters and splats) and associate them with request handlers. A key differentiator is its callback-based error handling, specifically designed to integrate directly into Node.js's HTTP server callback without introducing a complex middleware stack. It explicitly manages `404 Not Found` errors and provides a structured way to access URL parameters within handlers, making it suitable for minimalistic HTTP service implementations.
