## What it is
pat is a Sinatra-style pattern muxer for Go's net/http library, allowing route registration with URL parameters like /hello/:name. It is a small, classic Go library that integrates with the standard http.ServeMux.

## Use cases
- route http requests by pattern in go
- extract url parameters in go http handlers
- sinatra-style routing for go web servers
- register restful get/post routes in go
- minimal http router without a full framework

## When to choose
- you want a tiny, dependency-free router on top of net/http
- you prefer Sinatra-style pattern matching with :param captures
- you need a legacy-compatible muxer for older Go codebases

## When to avoid
- you need advanced routing features like middleware, groups, or regex constraints
- you are starting a new project and can use modern routers or Go 1.22+ net/http pattern matching
- you need active development and frequent updates

## Facets
- artifact type: library
- maturity: maintenance
- function: routing, web-framework, http-server
- domain: web-development, backend, apis
- platform: go, cross-platform
- tags: sinatra-style, pattern-muxer, net-http, url-parameters
