moddle

A utility library for working with meta-model based data structures.

What is it good for?

moddle offers you a concise way to define meta models in JavaScript. You can use these models to consume documents, create model elements, and perform model validation.

Define a schema

You start by creating a moddle schema. It is a JSON file which describes types, their properties, and relationships:

1{
2  "$schema": "https://unpkg.com/moddle/resources/schema/moddle.json",
3  "name": "Cars",
4  "uri": "http://cars",
5  "prefix": "c",
6  "types": [
7    {
8      "name": "Base",
9      "properties": [
10        { "name": "id", "type": "String", "isAttr": true }
11      ]
12    },
13    {
14      "name": "Root",
15      "superClass": [ "Base" ],
16      "properties": [
17        { "name": "cars", "type": "Car", "isMany": true }
18      ]
19    },
20    {
21      "name": "Car",
22      "superClass": [ "Base" ],
23      "properties": [
24        { "name": "name", "type": "String", "isAttr": true, "default": "No Name" },
25        { "name": "power", "type": "Integer", "isAttr": true },
26        { "name": "similar", "type": "Car", "isMany": true, "isReference": true },
27        { "name": "trunk", "type": "Element", "isMany": true }
28      ]
29    }
30  ]
31}

You may attach the provided JSON schema to get your moddle descriptor validated by code editor.

Instantiate moddle

You can instantiate a moddle instance with a set of defined schemas:

1import { Moddle } from 'moddle';
2
3var cars = new Moddle([ carsJSON ]);

Create objects

Use a moddle instance to create objects of your defined types:

1var taiga = cars.create('c:Car', { name: 'Taiga' });
2
3console.log(taiga);
4// { $type: 'c:Car', name: 'Taiga' };
5
6
7var cheapCar = cars.create('c:Car');
8
9console.log(cheapCar.name);
10// "No Name"
11
12
13// really?
14cheapCar.get('similar').push(taiga);

Introspect things

Then again, given the knowledge moddle has, you can perform deep introspection:

1var carDescriptor = cheapCar.$descriptor;
2
3console.log(carDescriptor.properties);
4// [ { name: 'id', type: 'String', ... }, { name: 'name', type: 'String', ...} ... ]

Access extensions

moddle is friendly towards extensions and keeps unknown any properties around:

1taiga.set('specialProperty', 'not known to moddle');
2
3console.log(taiga.get('specialProperty'));
4// 'not known to moddle'

It also allows you to create any elements for namespaces that you did not explicitly define:

1var screwdriver = cars.createAny('tools:Screwdriver', 'http://tools', {
2  make: 'ScrewIt!'
3});
4
5car.trunk.push(screwdriver);
