graphql-core-promise
Add support for promise-based dataloaders and resolvers to graphql-core v3+
Decision gist · record as of 2026-08-14
Yes, if you are migrating from graphene 2 to graphene 3 and have significant promise-based resolver code you want to preserve without rewriting. The low install friction and permissive license make it a practical bridge. However, the aging maintenance status (525 days since last release) means you should verify compatibility with your target graphql-core version and be prepared to maintain a fork if upstream support lapses.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires graphql-core v3+ and Python 3.10 or later; graphene-django 3 if used with Django.
- Low install friction; pure Python wheel with only two runtime dependencies (graphql-core and promise).
- Maintenance status is aging—last release was 525 days ago, though the repository remains active with a recent commit on 2025-03-07 and no archival.

What it is and what it does
graphql-core-promise bridges the gap between promise-based patterns (common in graphene 2 and JavaScript GraphQL libraries) and graphql-core v3+, which defaults to asyncio. It provides a drop-in ExecutionContext replacement that translates asyncio code into promise-based equivalents, allowing existing dataloaders and resolvers written for promise patterns to work without rewriting.
The package is particularly useful for teams migrating from graphene 2 to graphene 3 who have invested in promise-based resolver logic and want to avoid a full asyncio refactor. It integrates cleanly with graphene-django by accepting an execution_context_class argument, making it a minimal integration point rather than a wholesale architecture change.
Use it for
- Migrate graphene 2 projects to graphene 3 without rewriting all promise-based dataloaders and resolvers.
- Use promise-based patterns in graphql-core v3+ when your team is more familiar with promise semantics than asyncio.
- Integrate graphql-core-promise with graphene-django by passing PromiseExecutionContext to GraphQLView.
- Maintain backward compatibility with existing promise-based GraphQL resolver libraries during a major version upgrade.
