Overview

Strawberry GraphQL 0.200, released on September 1, 2023, migrates to Pydantic v2 and improves integrations.

Main Features

Pydantic v2 support

Strawberry types can be created from Pydantic v2 models, benefiting from faster validation.

python 
import strawberry
from pydantic import BaseModel

class UserModel(BaseModel):
    name: str
    age: int

@strawberry.experimental.pydantic.type(model=UserModel)
class User:
    name: strawberry.auto
    age: strawberry.auto

Improved integrations

Django, FastAPI, and Flask integrations are updated for better performance.

python 
import strawberry
from strawberry.fastapi import GraphQLRouter

@strawberry.type
class Query:
    @strawberry.field
    def hello(self, name: str = 'World') -> str:
        return f'Hello {name}'

schema = strawberry.Schema(query=Query)
router = GraphQLRouter(schema)
