Usage

const traverse = require('json-schema-traverse');
const schema = {
  properties: {
    foo: {type: 'string'},
    bar: {type: 'integer'}
  }
};

traverse(schema, cb);
// cb is called 3 times with:
// 1. root schema
// 2. {type: 'string'}
// 3. {type: 'integer'}

Callback function is called for each schema object (not including draft-06 boolean schemas), including the root schema. Schema references ($ref) are not resolved, they are passed as is.

Callback is passed these parameters:

Traverse objects in all unknown keywords

const traverse = require('json-schema-traverse');
const schema = {
  mySchema: {
    minimum: 1,
    maximum: 2
  }
};

traverse(schema, {allKeys: true}, cb);
// cb is called 2 times with:
// 1. root schema
// 2. mySchema

Without option allKeys: true callback will be called only with root schema.
