## What it is
A Symfony PHP component that manages URL generation and versioning of web assets such as CSS, JavaScript, and image files. It supports asset packages, versioning strategies for cache busting, base path relocation, and multiple CDN support.

## Use cases
- generate URLs for css and javascript files in php templates
- version static assets to bust browser cache
- serve assets from multiple CDNs
- move asset files without updating every template
- group assets into packages with a common base path

## When to choose
- you're building a PHP or Symfony web app and need consistent asset URL handling
- you need cache-busting versioning strategies for static files
- you want to serve assets from one or more CDNs

## When to avoid
- you're using a frontend bundler like Webpack Encore or Vite that already handles asset URLs and hashing
- your app is extremely simple and hard-coded asset paths are fine
- you're not working in PHP

## Facets
- artifact type: library
- maturity: stable
- function: routing, templating
- domain: web-development, frontend
- platform: php
- tags: symfony-component, asset-management, url-generation, cache-busting, cdn, versioning, php, web-server
