This is a demo to show how to produce an OpenAPI document from Haskell types using autodocodec, and in particular how to encode a sum type in OpenAPI.
Relevant Haskell code is in serverc/src/Lib.hs.
Generated OpenAPI document is in openapi.json.
Generated TypeScript type definitions are in client-typescript/src-generated/models
To emit an updated OpenAPI document run:
$ make openapi.json
To emit updated OpenAPI and generated client code run:
$ make
TypeScript types are generated using
openapi-typescript-codegen.
When working with sum types be sure to use the --useUnionTypes option to the
openapi CLI tool to generate literal types for your discriminator fields.
