GraphQL¶

AsFastAPI is based on theASGI standard, it's very easy to integrate anyGraphQL library also compatible with ASGI.

You can combine normal FastAPIpath operations with GraphQL on the same application.

GraphQL Libraries¶

Here are some of theGraphQL libraries that haveASGI support. You could use them withFastAPI:

• Strawberry 🍓
  • Withdocs for FastAPI
• Ariadne
  • Withdocs for FastAPI
• Tartiflette
  • WithTartiflette ASGI to provide ASGI integration
• Graphene
  • Withstarlette-graphene3

GraphQL with Strawberry¶

If you need or want to work withGraphQL,Strawberry is therecommended library as it has the design closest toFastAPI's design, it's all based ontype annotations.

Depending on your use case, you might prefer to use a different library, but if you asked me, I would probably suggest you tryStrawberry.

Here's a small preview of how you could integrate Strawberry with FastAPI:

importstrawberryfromfastapiimportFastAPIfromstrawberry.fastapiimportGraphQLRouter@strawberry.typeclassUser:name:strage:int@strawberry.typeclassQuery:@strawberry.fielddefuser(self)->User:returnUser(name="Patrick",age=100)schema=strawberry.Schema(query=Query)graphql_app=GraphQLRouter(schema)app=FastAPI()app.include_router(graphql_app,prefix="/graphql")

You can learn more about Strawberry in theStrawberry documentation.

And also the docs aboutStrawberry with FastAPI.

OlderGraphQLApp from Starlette¶

Previous versions of Starlette included aGraphQLApp class to integrate withGraphene.

It was deprecated from Starlette, but if you have code that used it, you can easilymigrate tostarlette-graphene3, that covers the same use case and has analmost identical interface.
