## What it is
FastRoute is a fast, regular expression-based HTTP request router library for PHP. It dispatches HTTP method and URI pairs to registered handlers using route patterns with typed placeholders.

## Use cases
- route http requests in a php application
- match urls with dynamic placeholders like /user/{id}
- build a custom php framework or microkernel
- handle 404 and 405 responses for unmatched routes
- define routes for multiple http methods
- speed up routing in a high-traffic php api

## When to choose
- you need a fast, standalone router for a PHP 8.1+ project
- you want regex-constrained route placeholders like {id:\d+}
- you are building your own framework or micro-framework and only need routing
- you need clear handling of NOT_FOUND and METHOD_NOT_ALLOWED dispatch results

## When to avoid
- you use a full framework (Laravel, Symfony) that already includes a router
- you need middleware, controllers, or other framework features beyond routing
- your project runs on PHP older than 8.1

## Facets
- artifact type: library
- maturity: stable
- function: routing, web-framework, http-server
- domain: web-development, backend, apis
- platform: php
