...It allows you to move your API to GraphQL with nearly zero effort and maintain both REST and GraphQL APIs. Our CLI tool also allows you get the GraphQL schema in Schema Definition Language. This library will fetch your swagger schema, convert it to a GraphQL schema and convert GraphQL parameters to REST parameters. From there you are control of making the actual REST call. This means you can reuse your existing HTTP client, use existing authentication schemes and override any part of the REST call. You can override the REST host, proxy incoming request headers along to your REST backend, add caching etc.
