In /src/examples/helper/graphiql.py
we implemented an helper for using graphiQL with strawberry.
import dataclasses
import strawberry
import strawberry.utils.graphiql
from socketify import App
from typing import List, Optional
from helpers.graphiql import graphiql_from
@strawberry.type
class User:
name: str
@strawberry.type
class Query:
@strawberry.field
def user(self) -> Optional[User]:
# self.context is the AppRequest
return User(name="Hello")
app = App()
app.get("/", lambda res, req: res.end(strawberry.utils.graphiql.get_graphiql_html()))
app.post("/", graphiql_from(Query))
# you can also pass an Mutation as second parameter
# app.post("/", graphiql_from(Query, Mutation))
app.listen(
3000,
lambda config: print("Listening on port http://localhost:%d now\n" % config.port),
)
app.run()
import strawberry
import strawberry.utils.graphiql
def graphiql_from(Query, Mutation=None):
if Mutation:
schema = strawberry.Schema(query=Query, mutation=Mutation)
else:
schema = strawberry.Schema(Query)
async def post(res, req):
# we can pass whatever we want to context, query, headers or params, cookies etc
context_value = req.preserve()
# get all incoming data and parses as json
body = await res.get_json()
query = body["query"]
variables = body.get("variables", None)
root_value = body.get("root_value", None)
operation_name = body.get("operation_name", None)
data = await schema.execute(
query,
variables,
context_value,
root_value,
operation_name,
)
res.cork_end(
{
"data": (data.data),
**({"errors": data.errors} if data.errors else {}),
**({"extensions": data.extensions} if data.extensions else {}),
}
)
return post
