Open API integration MVP

Product

Hot Chocolate

Is your feature request related to a problem?

To enable users to easily migrate existing open api services towards a GraphQL solution, an automated conversion of an open api spec into a GraphQL is desired.

The solution you'd like

The MVP should be capable of the following:

• a simple open api specification like the one from the example page Link is converted into a GraphQL schema
• the generated schema is used to automatically setup a HotChocolate server with Query and mutation types
• Get methods are translated into Query fields
• all other operations are translated into Mutation fields
• http client can be manipulated

What explicitly will not be part of the first MVP

• subscriptions
• relations like automatically turn id fields into typed fields which will resolve the object automatically

Start with the linked OpenAPI v3 example specifications and inspect the existing Hot Chocolate server and HTTP client integration points. Implement the stated MVP conversion and verify that GET operations become Query fields, other operations become Mutation fields, and the generated schema configures the server; subscriptions and automatic relations remain out of scope.
