Strawberry GraphQL @ 0.277.0

Released July 18, 2025 at 10:24 PM GMT+00:00

This release adds experimental support for GraphQL’s @defer and @stream directives, enabling incremental delivery of response data.

Note: this only works when using Strawberry with graphql-core>=3.3.0a9 .

Features

• @defer directive: Allows fields to be resolved asynchronously and delivered incrementally
• @stream directive: Enables streaming of list fields using the new strawberry.Streamable type
• strawberry.Streamable[T] : A new generic type for defining streamable fields that work with @stream

Configuration

To enable these experimental features, configure your schema with:

from strawberry.schema.config import StrawberryConfig
 
schema = strawberry.Schema(
    query=Query, config=StrawberryConfig(enable_experimental_incremental_execution=True)
)
