openapi-to-graphql

Generates GraphQL schemas based on data definitions in the OAS rather than endpoints, leading to a natural GraphQL interface that mirrors underlying data structures, as illustrated in the data-centric example image.

Leverages OAS link definitions to create nested data structures, enabling deeply nested GraphQL queries without manual resolver coding, shown in the links resolution diagram.

Creates resolvers that automatically translate GraphQL queries into REST API requests and map responses back, reducing boilerplate and simplifying integration, as detailed in the automatic query resolution feature.

Converts non-safe operations to GraphQL mutations and uses OAS callbacks for subscriptions, allowing full GraphQL capabilities like real-time updates on top of REST APIs, with examples provided in the mutations and subscriptions sections.
