## What it is
HttpRouter is a lightweight, high-performance HTTP request router (mux) for Go that supports path variables and method matching using a compressing radix tree. It is optimized for speed and low memory footprint, with zero-garbage matching and automatic path correction.

## Use cases
- route http requests in a go web service
- handle url path parameters in go
- replace net/http servemux with a faster router
- build a high performance rest api in go
- redirect trailing slashes and fix url paths automatically
- route large numbers of endpoints efficiently

## When to choose
- you need a fast, minimal router with path parameters in Go
- you want zero-allocation request dispatching for latency-sensitive services
- you have many routes or long paths and need efficient matching

## When to avoid
- you need a full web framework with middleware, templating, or validation built in
- you want wildcard or regex-based route matching with flexible priority rules
- you prefer the standard library's http.ServeMux for maximal compatibility

## Facets
- artifact type: library
- maturity: stable
- function: routing, http-server, middleware
- domain: web-development, backend, apis, performance
- platform: go, windows, cross-platform
- tags: http-router, mux, radix-tree, zero-allocation, path-parameters, linux, macos
