Minimal example demonstrating promise-based resolver with graphql-core.

import asyncio from graphql import graphql_sync, build_schema from graphql_core_promise import promise_resolver schema = build_schema(''' type Query { hello: String } ''') async def resolve_hello(root, info): await asyncio.sleep(0.01) return 'Hello, world!' # Use promise_resolver middleware result = graphql_sync(schema, '{ hello }', middleware=[promise_resolver]) print(result.data)

Debug

Known issues

breakingVersion 3.0+ renamed the package and dropped Python 3.7/3.8 support. The old package `graphql-core-promise` was a different project; this is a fork by fellowapp with a breaking change to import paths.

fix

Update imports from `graphql_core.promise` to `graphql_core_promise`.

affects: >=3.0.0

gotchaPromiseMiddleware expects middleware context to be dict-like. Passing a custom object without `__getitem__` and `__setitem__` or using non-dict middleware chain may cause AttributeError.

fix

Ensure middleware list elements support dict-like access, or use plain dicts.

affects: all
