Cyclical objects

Despite supporting recursive schemas, passing cyclical data into Zod will cause an infinite loop in some cases.

You can protect against cyclical objects starting an infinite loop (at a performance cost) with the following approach (using the above jsonSchema as an example):

	import * as z from "zod";

	export const a = z.object({
	a: z.string(),
	b: z.string(),
	c: z.string(),
	});

	export const b = a.omit({
	a: true,

	import { randomString } from "./benchUtil.js";
	import { metabench } from "./metabench.js";

	export function lazyWithInternalProp<T>(getter: () => T) {
	return {
	__value: undefined as T,
	get value() {
	if (this.__value) return this.__value;
	const value = getter();
	this.__value = value;

	function lazy<T>(getter: () => T): { value: T } {
	return {
	get value() {
	const value = getter();
	Object.defineProperty(this, "value", { value });
	return value;
	},
	};
	}

	import * as z from "zod";

	const mySchema = z.string();

	// there is a global schema registry
	z.globalRegistry; // => ZodRegistry<unknown, z.ZodType>

	// add schema to registry w/ associated metadata
	z.globalRegistry.add(mySchema, { name: "foo", description: "bar" });
	// equivalent convenience method (returns mySchema)

	"command": "editor.action.goToDeclaration"
	},
