OpenAPIGraphQL

OpenAPIGraphQL is a specification that aims to bridge the gap between OpenAPI and GraphQL. Its primary goal is to allow developers to define a GraphQL API using the OpenAPI specification format. This enables the use of existing OpenAPI tooling and workflows for managing and documenting GraphQL services.

The specification describes how to map GraphQL schema definitions and operations to OpenAPI objects, such as paths, operations, and schemas. It defines conventions for representing GraphQL types, fields, arguments, and mutations within an OpenAPI document. This includes mapping GraphQL fields to OpenAPI parameters and responses, and GraphQL types to OpenAPI schema objects.

By leveraging OpenAPI, OpenAPIGraphQL facilitates tasks like generating API documentation, creating client SDKs, and performing static analysis of GraphQL APIs. It also allows for the integration of GraphQL services into existing RESTful API management platforms that are built around OpenAPI. The specification provides a standardized way to describe a GraphQL endpoint in a format that is widely understood and supported by the API development ecosystem. This can simplify the process of adopting and managing GraphQL services, especially for organizations already invested in OpenAPI.
