GraphQL with Strawberry¶

If you need or want to work with GraphQL, Strawberry is the recommended library as it has the design closest to FastAPI's design, it's all based on type annotations.

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

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

import strawberry
from fastapi import FastAPI
from strawberry.asgi import GraphQL


@strawberry.type
class User:
    name: str
    age: int


@strawberry.type
class Query:
    @strawberry.field
    def user(self) -> User:
        return User(name="Patrick", age=100)


schema = strawberry.Schema(query=Query)


graphql_app = GraphQL(schema)

app = FastAPI()
app.add_route("/graphql", graphql_app)
app.add_websocket_route("/graphql", graphql_app)
