Graphene
Graphene is a library and framework for building type-safe GraphQL APIs and schemas using Python objects and resolvers. It provides a system for mapping internal data models to typed GraphQL schemas, enabling the creation of servers that process queries and execute resolvers to return structured data.
The project includes a full implementation of the Relay specification, providing standardized patterns for global object identification and cursor-based pagination. It utilizes a class-based approach to schema definition and supports interface-based type inheritance.
The framework covers a broad range of API development capabilities, including the management of data mutations, custom scalar mapping, and the integration of multiple backend data sources into a unified data layer.
Features
- GraphQL APIs - Provides a full framework for building type-safe GraphQL APIs and schemas using Python.

- Server Libraries - Provides the backend infrastructure to process GraphQL queries and execute Python resolvers.
- Backend Data Access Layers - Connects Python-based data models and backend databases to a GraphQL API layer.
- GraphQL Mutation Implementations - Provides a mechanism to define and execute mutations that modify server-side data.
- GraphQL Mutation Management - Provides a standardized interface for implementing server-side data mutations and returning updated results.
- Class-Based Schema Mapping - Uses Python classes to define the structure of GraphQL object types and fields.
- Resolver-Based Fetching - Uses resolver functions to map schema fields to data retrieval logic from various sources.
- Field Resolvers - Implements a resolver-based system to fetch specific values for API fields from root objects.
