json-schema-walker v2.0.0

JSON Schema Walker

Loosely based on CloudFlare's json schema tools

A system that visits all schema objects in a JSON Schema document and makes callbacks before and/or after visiting all of the current schema object's subschemas.

Usage

import { Walker } from "json-schema-walker";
const schema = {
  // your json schema
};
const walker = new Walker<T>();
await walker.loadSchema(schema, {
  cloneSchema: true,
  dereference: false,
  dereferenceOptions: {
    dereference: {
      circular: "ignore",
    },
  },
});
const convertSchema = (schema) => {
  // do something with the schema properties
};
await walker.walk(convertSchema, walker.vocabularies.DRAFT_07);
const updatedSchema = walker.rootSchema;

Circular references

Passing the options

{
  "dereferenceOptions": {
    "dereference": {
      "circular": "ignore"
    }
  }
}

will dereference all non-circular references in your schema.
