Package Exports

json-schema-migrate

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (json-schema-migrate) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

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).

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
