API Platform is an open-source PHP framework for Symfony and Laravel that follows semantic versioning and a stable release cycle.
A step-by-step demonstration shows how to create a new Symfony project, add an API resource, and generate CRUD endpoints for a book entity.
API Platform provides auto-generated documentation via OpenAPI, native GraphQL support, front-end integrations, and a schema generator for migrations.
The framework uses the Symfony Serializer for data transformation and content negotiation, supporting architectures like CRUD, CQRS, and DDD.
API Platform supports various structured formats like JSON-LD and JSON API, patch formats like JSON Merge Patch, and standardized error formats like Problem Details.
You can extend API Platform with unsupported formats by creating custom normalizer and encoder classes using Symfony's serialization component.
The framework allows for both global configuration for project-wide settings and local configuration to customize specific resources and operations.
Leverage native validation from Symfony or Laravel and secure operations using roles, custom voters, and standard authentication methods like JWT and OAuth.
Go beyond default data sources like Doctrine or Eloquent by implementing custom state providers to fetch data from external APIs or other sources.
Use state processors to customize data persistence, map data with DTOs, and apply powerful built-in or custom filters to your resource collections.
API Platform automatically generates interactive documentation using Swagger UI or Redoc, which can be customized by extending the OpenAPI factory.
