Graphene

What Graphene is

Graphene is a free Python library for building GraphQL APIs with a code-first workflow. Developers describe server data in a statically typed schema, and queries can return only the fields requested. It supports data from Django, SQLAlchemy, Mongo, and custom Python objects, with documented integrations for Django, Flask, SQLAlchemy, Google App Engine, Mongo, Starlette, and FastAPI. Graphene works with clients including Relay, Apollo, and gql; its Relay utilities cover nodes, connections, and mutations. The documentation also covers middleware, dataloading, file uploads, subscriptions, query validation, depth limits, and disabling introspection. A test client can simulate queries and mutations and inspect the responses. Install it with pip using the README command `pip install "graphene>=3.1"`. The documented Graphene 3.0 quickstart lists Python 3.6 through 3.10 and PyPy. Graphene is self-hosted on Linux, is MIT-licensed, and the project invites users to join its Discord community and contribute through open issues.
