## What it is
The Symfony Routing component maps HTTP requests to configuration variables, matching incoming URLs against defined routes and generating URLs from route names. It is a standalone PHP library usable independently or as part of the Symfony framework.

## Use cases
- match incoming http requests to controllers in php
- generate seo-friendly urls from route names
- define routes with yaml php or attributes
- validate route parameters and handle optional parameters
- implement localized and sub-domain routing
- build a custom php framework or microkernel

## When to choose
- you need battle-tested routing in a PHP project
- you want URL matching and generation decoupled from a full framework
- you need localized, prefixed, or attribute-based route configuration

## When to avoid
- your framework already bundles a router
- you need client-side or SPA routing
- you are not working in PHP

## Facets
- artifact type: library
- maturity: stable
- function: routing, web-framework, http-server
- domain: web-development, backend, apis
- platform: php, cross-platform
- tags: url-generation, route-matching, symfony-component, router, uri, web-server
