Strawberry comes with a basic Sanic integration. It provides a view that you can use to serve your GraphQL schema:

from strawberry.sanic.views import GraphQLView
from api.schema import Schema
app = Sanic(__name__)
GraphQLView.as_view(schema=schema, graphiql=True),


The GraphQLView accepts two options at the moment:

  • schema: mandatory, the schema created by strawberry.Schema.
  • graphiql: optional, defaults to True, whether to enable the GraphiQL interface.

Extending the view

The base GraphQLView class can be extended by overriding the following methods:

  • async get_context(self) -> Any
  • get_root_value(self) -> Any
  • process_result(self, result: ExecutionResult) -> GraphQLHTTPResponse


By overriding GraphQLView.get_context you can provide a custom context object for your resolvers. You can return anything here; by default GraphQLView returns a dictionary with the request.

class MyGraphQLView(GraphQLView):
async def get_context(self, request) -> Any:
return {"example": 1}
class Query:
def example(self, info: Info) -> str:
return str(info.context["example"])

Here we are returning a custom context dictionary that contains only one item called "example".

Then we can use the context in a resolver. In this case the resolver will return 1.


By overriding GraphQLView.get_root_value you can provide a custom root value for your schema. This is probably not used a lot but it might be useful in certain situations.

Here's an example:

class MyGraphQLView(GraphQLView):
def get_root_value(self) -> Any:
return Query(name="Patrick")
class Query:
name: str

Here we configure a Query where requesting the name field will return "Patrick" through the custom root value.


By overriding GraphQLView.process_result you can customize and/or process results before they are sent to a client. This can be useful for logging errors, or even hiding them (for example to hide internal exceptions).

It needs to return an object of GraphQLHTTPResponse and accepts the execution result.

from strawberry.http import GraphQLHTTPResponse
from strawberry.types import ExecutionResult
from graphql.error import format_error as format_graphql_error
class MyGraphQLView(GraphQLView):
def process_result(
self, result: ExecutionResult
) -> GraphQLHTTPResponse:
data: GraphQLHTTPResponse = {"data":}
if result.errors:
data["errors"] = [format_graphql_error(err) for err in result.errors]
return data

In this case we are doing the default processing of the result, but it can be tweaked based on your needs.
