Strawberry GraphQL @ 0.240.0

Released

This release adds support for schema-extensions in subscriptions.

Here’s a small example of how to use them (they work the same way as query and mutation extensions): 

import asyncio
from typing import AsyncIterator


import strawberry
from strawberry.extensions.base_extension import SchemaExtension




@strawberry.type
class Subscription:
    @strawberry.subscription
    async def notifications(self, info: strawberry.Info) -> AsyncIterator[str]:
        for _ in range(3):
            yield "Hello"




class MyExtension(SchemaExtension):
    async def on_operation(self):
        # This would run when the subscription starts
        print("Subscription started")
        yield
        # The subscription has ended
        print("Subscription ended")




schema = strawberry.Schema(
    query=Query, subscription=Subscription, extensions=[MyExtension]
)
