Cyclic references within definitions

[bacebu4]

Representation example

Given the input

interface User {
  id: string;
  headUser?: User;
}

export const userSchema: z.ZodType<User> = z.lazy(() =>
  z.object({
    id: z.string(),
    headUser: userSchema.optional()
  })
);

Produces the following output

{
    "$schema": "http://json-schema.org/draft-07/schema#",
    "type": "object",
    "properties": {
        "user": {
            "$ref": "#/properties/headUser"
        }
    },
    "required": [
        "user"
    ],
    "additionalProperties": false,
    "definitions": {
        "User": {
            "type": "object",
            "properties": {
                "id": {
                    "type": "string"
                },
                "headUser": {
                    "type": "object",
                    "properties": {
                        "id": {
                            "type": "string"
                        },
                        "headUser": {
                            "$ref": "#/properties/headUser"
                        }
                    },
                    "required": [
                        "id"
                    ],
                    "additionalProperties": false
                }
            },
            "required": [
                "id"
            ],
            "additionalProperties": false
        }
    }
}

🤦

I will need to rebuild the reference handling to account for this, which has been a long time coming anyway since it's a bit of a mess. I've marked the feature as experimental in the meantime. I have a ton of stuff to do at work right now so not sure when I'll be able to get to it though.

Got you
I'll have a vacation next week so I might to provide some help as well (if you still won't be able to deliver the feature)

Fixed in 3.20.0
