How to inherits from two definitions?

[odykyi]

I have interface on TS, and it works, because I define this interface manually

// GetMysqlSuccessPayload.d.ts
import { MysqlPayload } from '../../MysqlPayload ';
import { MysqlCredential } from '../MysqlCredential ';

export interface GetMysqlSuccessPayload extends MysqlPayload, MysqlCredential {

}

I want not write manually interface in typescript, I want to use library json-schema-to-typescript, but I can't

How I can rewrite this TS code to json-schema, and how I can use json-schema-to-typescript extends from two interfaces?
now library json-schema-to-typescript doesn't support inheritance from more than two interfaces?

and I try to use extends in basicTypes.json

{
  "definitions": {
    "GetMysqlSuccessPayload ": {
      "title": "GetMysqlSuccessPayload",
      "type": "object",
      "extends": {
        "$ref": "#/definitions/MysqlPayload ",  // How to inherits from two definitions
        "$ref": "#/definitions/MysqlCredential "
      }
    }
    .......
  }
}

Hey there @odykyi! You want $allOf:

{
  "definitions": {
    "GetMysqlSuccessPayload ": {
      "title": "GetMysqlSuccessPayload",
      "type": "object",
      "$allOf": [
        {"$ref": "#/definitions/MysqlPayload"},
        {"$ref": "#/definitions/MysqlCredential"}
      ]
    }
  }
}

See example output here, or read more here.
