Recursive schemas and contributions to swagger-ui

[souenzzo]

Hello, I'm working on a project that uses a spec that is recursive, and due an old issue (from 2017 - see note 1), swagger-ui can't render it.

It can easily reproduced (as in note 3)

I would like to know: I'm the only one using recursive schemas? There is some kind of workaround?

I would like to work on a fix to it. But a few days ago I wrote a PR (note 2) to fix another issue, and it seems to be ignored by the main contributors.

So before write another PR, I would like to ask: how to not be ignored by the community?

1. https://github.com/swagger-api/swagger-ui/issues/3325

2. https://github.com/swagger-api/swagger-ui/pull/8400

3. Enter https://editor-next.swagger.io/ and paste this schema

openapi: 3.0.3
info: {title: "recur", version: "1.0.0"}
paths:
  /pet:
    put:
      responses:
        default:
          description: Successful operation
          content:
            application/json:
              schema:
                $ref: '#/components/schemas/Pet'
components:
  schemas:
    Pet:
      type: object
      properties:
        name: {type: number}
        myself: {$ref: "#/components/schemas/Pet"}

Hi @souenzzo ,

First thanks for the PR, my apologies for our lack of attention there. We're looking for ways to improve, but it's a slow process.

Regarding the recursive issue, you're referring to the following UI showing an empty object? 

From when last I recall, this is an issue to do with how swagger-client (the resolver part) provides the serializable definition. 

We've recently updated the underlying engine to use ApiDOM which has the functionality to provide meta-data (like if something is recursive), but it's still using the same channels to provide a JS object to SwaggerUI. All of this is to say, this may be a challenging feature to implement but with the recent changes, it may be feasible. 

If you are interested in a PR, I'd first raise an empty draft PR. And since it's tough to get attention, ping my username (ponelat) until we improve our processes.
