REST and GraphQL framework to build modern API-driven projects (server-side and client-side)
API Platform is a next-generation web framework designed to easily create API-first projects without compromising extensibility and flexibility:
The official project documentation is available on the API Platform website.
API Platform embraces open web standards (OpenAPI, JSON-LD, GraphQL, Hydra, HAL, JSONAPI, JWT, OAuth, HTTP...) and the Linked Data movement. Your API will automatically expose structured data in Schema.org / JSON-LD. It means that your API Platform application is usable out of the box with technologies of the semantic web.
It also means that your SEO will be improved because Google leverages these formats.
