json-schema-traverse

Traverse JSON Schema passing each schema object to callback

Install

npm install json-schema-traverse

Usage

1const traverse = require('json-schema-traverse');
2const schema = {
3  properties: {
4    foo: {type: 'string'},
5    bar: {type: 'integer'}
6  }
7};
8
9traverse(schema, {cb});
10// cb is called 3 times with:
11// 1. root schema
12// 2. {type: 'string'}
13// 3. {type: 'integer'}
14
15// Or:
16
17traverse(schema, {cb: {pre, post}});
18// pre is called 3 times with:
19// 1. root schema
20// 2. {type: 'string'}
21// 3. {type: 'integer'}
22//
23// post is called 3 times with:
24// 1. {type: 'string'}
25// 2. {type: 'integer'}
26// 3. root schema
27

Callback function cb is called for each schema object (not including draft-06 boolean schemas), including the root schema, in pre-order traversal. Schema references ($ref) are not resolved, they are passed as is. Alternatively, you can pass a {pre, post} object as cb, and then pre will be called before traversing child elements, and post will be called after all child elements have been traversed.

Callback is passed these parameters:

schema: the current schema object
JSON pointer: from the root schema to the current schema object
root schema: the schema passed to traverse object
parent JSON pointer: from the root schema to the parent schema object (see below)
parent keyword: the keyword inside which this schema appears (e.g. properties, anyOf, etc.)
parent schema: not necessarily parent object/array; in the example above the parent schema for {type: 'string'} is the root schema
index/property: index or property name in the array/object containing multiple schemas; in the example above for {type: 'string'} the property name is 'foo'

Traverse objects in all unknown keywords

1const traverse = require('json-schema-traverse');
2const schema = {
3  mySchema: {
4    minimum: 1,
5    maximum: 2
6  }
7};
8
9traverse(schema, {allKeys: true, cb});
10// cb is called 2 times with:
11// 1. root schema
12// 2. mySchema

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