A package to convert JSON schema (draft 4+) objects into Zod schemas in the form of Zod objects at runtime.

Installation

1npm install @n8n/json-schema-to-zod

Simple example

1import { jsonSchemaToZod } from "json-schema-to-zod";
2
3const jsonSchema = {
4  type: "object",
5  properties: {
6    hello: {
7      type: "string",
8    },
9  },
10};
11
12const zodSchema = jsonSchemaToZod(myObject);

Overriding a parser

You can pass a function to the overrideParser option, which represents a function that receives the current schema node and the reference object, and should return a zod object when it wants to replace a default output. If the default output should be used for the node just return undefined.
