HttpRouter
A high performance HTTP request router that scales well
HttpRouter is a lightweight high performance HTTP request router (also called multiplexer or just mux for short) for Go. In contrast to the default mux of Go's net/http package, this router supports variables in the routing pattern and matches against the request method. It also scales better. The router is optimized for high performance and a small memory footprint. It scales well even with very long paths and a large number of routes. A compressing dynamic trie (radix tree) structure is used for efficient matching. With other routers, like http.ServeMux, a requested URL path could match multiple patterns. Therefore they have some awkward pattern priority rules, like longest match or first registered, first matched. By design of this router, a request can only match exactly one or no route. As a result, there are also no unintended matches, which makes it great for SEO and improves the user experience.
