JSON Schema to SimpleSchema Converter

Converts a JSON schema document to a SimpleSchema object, for use with Collection2 and AutoForm.

Install

meteor add bshamblen:json-simple-schema

Use

Simply load the contents of your JSON schema document from your local file system, or from a URL, and pass the parsed JSON object to the JSONSchema constructor:

toSimpleSchema

Generates an instance of SimpleSchema, ready to attach to your Meteor collection.

var jsonSchemaDoc = JSON.parse($.ajax({
	type: 'GET',
	url: 'http://example.com/path-to-json-schema-file',
	async: false
}).responseText);

var jsonSchema = new JSONSchema(jsonSchemaDoc);
var simpleSchema = jsonSchema.toSimpleSchema();

YourModel = new Mongo.Collection('somecollection');
YourModel.attachSchema(simpleSchema);

toSimpleSchemaProps

Generates just the schema properties object, which can be modified prior to manually creating an instance of SimpleSchema.

var jsonSchemaDoc = JSON.parse($.ajax({
	type: 'GET',
	url: 'http://example.com/path-to-json-schema-file',
	async: false
}).responseText);

var jsonSchema = new JSONSchema(jsonSchemaDoc);
var props = jsonSchema.toSimpleSchemaProps();

props.extraProperty = {
	type: String,
	optional: true
}

var simpleSchema = new SimpleSchema(props);

YourModel = new Mongo.Collection('somecollection');
YourModel.attachSchema(simpleSchema);

Disclaimer

This is the first iteration of this project, with minimal functionality. It currently supports base data types (including arrays), inline sub-objects and many of the validation options:

• title
• minimum
• maximum
• exclusiveMinimum
• exclusiveMaximum
• minLength
• maxLength
• enum
• minItems
• maxItems
• default
• pattern
• required
• Now supports internal $ref (thanks @bpatridge)

TODO

• Add support for external $ref schemas, from a URI.
