generator should be able to generate generic types

[czlowiek488]

Context

I have specification written like below.

components:
  schemas:
    Envelope:      
      $id: Envelope
      description: "Envelope shared between messages"
      type: object
      required: [event, eventId]
      properties:
        eventId:
          type: string
        event:
          $id: Event
          type: object
messages:
  project.Created:
    payload:
      $id: MessageProjectCreated
      allOf:
        - $ref: "#/components/schemas/Envelope"
        - type: object
          required: [event]
          properties:
            eventName:
              const: "tms.event.project.created"
            event:
              type: object
              $id: EventProjectCreated
              required: [project]
              properties:
                project:
                  type: object

this is generating interface like this

export interface MessageProjectCreated {
    eventId: string;
    event: EventProjectCreated;
    eventName: "tms.event.project.created";
}

Reason#1

I have few events on event bus which are not coming from specification, but they are using Envelope from specification. Specifcation tells what events are send by my client, but I sometimes send my own events to the same event bus. For them I have to write my own Envelope and if Envelope will be changed in specification I will not be able to see differences.

Reason#2

In generic event handler I do not know which event is inside Envelope, it can be literally everything even an empty object in my test scenario.

Description

I would like to generate something like here for each $ref used in specs.

export interface Envelope<T> {
    eventId: string;
    event: T;
}

export interface MessageProjectCreated extends Envelope<EventProjectCreated> {
   eventName: tms.event.project.created;
 };

and I would be able to do something like

export const genericEventHandler = (event: Envelope<any>) => {...};

There can be many reasons why some specific issue has no activity. The most probable cause is lack of time, not lack of interest. AsyncAPI Initiative is a Linux Foundation project not owned by a single for-profit company. It is a community-driven initiative ruled under open governance model.
