json-schema-migrate

Migrate JSON-Schema to draft-06

Purpose

This package allows to migrate JSON-schemas to draft-06 specification.

It supports:

• draft-04 schemas
• draft-04 hyper-schemas
• Ajv v5 schemas (special extended mode in Ajv 4.x.x, deprecated from version 5.0.0).

Install

npm install json-schema-migrate

Usage

var migrate = require('json-schema-migrate');
var schema = {
  id: 'my-schema',
  minimum: 1,
  exclusiveMinimum: true
};
migrate.draft6(schema /*, options */);

console.log(schema);
// {
//  $id: 'my-schema',
//  exclusiveMinimum: 1
// }

Changes in schemas after migration

• id is replaced with $id
• $schema value becomes draft-06 meta-schema (or draft-06 hyper-schema)
• boolean form of exclusiveMaximum/Minimum is replaced with numeric form
• enum with a single allowed value is replaced with const
• Ajv v5 constant is replaced with const
• empty schema is replaced with true
• schema {"not":{}} is replaced with false

Options

• v5 - use v5 by default (if $schema keyword is absent)
• validateSchema - pass false to skip schema validation
