HttpRouter is a lightweight and a high-performance HTTP request router for Go; it's also called multiplexer (or mux, for short). Unlike the default mux of Go's net/HTTP package, this customized mux helps to bind the routing variables in the routing pattern and matches against the request method. The best part of this router is its small memory footprint, optimized for high performance. As this custom router employs a compressing radix tree structure for efficient matching of the long paths, a large number of routes is possible with the custom router.
