## What it is
FOSRestBundle is a Symfony bundle providing tools for rapidly building RESTful APIs, including a format-agnostic view layer, Accept header negotiation, request body decoding, and RFC 7807-compatible exception rendering. It integrates with the Symfony Serializer or JMS Serializer components.

## Use cases
- build a REST API with Symfony
- negotiate response formats from Accept headers
- decode JSON request bodies into controller parameters
- return RFC 7807 problem+ error responses
- map exceptions to HTTP status codes
- version a REST API

## When to choose
- you are building a REST API on Symfony and want content negotiation and view-layer conventions
- you need consistent exception-to-HTTP-status mapping and RFC 7807 error rendering
- you want loosely coupled listeners for body decoding, param fetching, and versioning

## When to avoid
- you are not using the Symfony framework
- you only need a simple JSON API where Symfony's built-in attributes and serializer suffice
- you are building a GraphQL or non-REST API

## Facets
- artifact type: plugin
- maturity: stable
- function: api-framework, middleware, serialization, routing
- domain: web-development, backend, apis
- platform: php
