JSON Schema Traverse

This package exports a method that will traverse a JSON-Schema, calling a "mutation" function for each sub schema found. It is useful for building tools to work with JSON Schemas.

Features

• circular reference detection & handling
• synchronous - doesn't touch the filesystem or make network requests.
• easily perform schema mutations while traversing
• optional mutability (toggle updating original schema object)
• returns JSONPaths as it traverses

Getting Started

npm install @json-schema-tools/traverse

const traverse = require("@json-schema-tools/traverse").default;
//import traverse from "@json-schema-tools/traverse"

const mySchema = {
  title: "baz",
  type: "object",
  properties: {
    foo: {
      title: "foo",
      type: "array",
      items: { type: "string" }
    },
    bar: {
      title: "bar",
      anyOf: [
        { title: "stringerific", type: "string" },
        { title: "numberoo", type: "number" }
      ]
    }
  }
};

traverse(mySchema, (schemaOrSubschema) => {
  console.log(schemaOrSubschema.title);
});
