Usage (client-side) :

On your Web page, load files : "Bootstrap,js", "Types,js", "Tools.js", "Namespaces.js", "Doodad.js", "Client.js".

On page load, create the root namespace :

var root = window.createRoot(window.DD_MODULES);

By default, Doodad is running in production mode, which disables every validations. You may want to enable them by also loading the file "Debug.js" and enabling object properties this way :

var root = window.createRoot(window.DD_MODULES, {startup: {settings: {enableProperties: true}}});

That's it. Now you can create your own objects.

Usage (server-side with nodejs) :

Installation : npm install doodad-js --save

By default, Doodad is running in production mode, which disables every validations. You may want to activate the development mode by setting the "NODE_ENV" environment variable :

Windows :

set NODE_ENV=development

Linux :

export NODE_ENV=development

Now, from Node.js, create the root namespace :

var root = require('doodad-js').createRoot();

That's it. Now you can create your own objects.

At startup, only bootstrap modules are loaded. But you can load other Doodad modules from this way :

const DD_MODULES = {};
require('doodad-js-io').add(DD_MODULES);
...
function onready() {
...
}
root.Doodad.Namespaces.loadNamespaces(onready, false, DD_MODULES);

Example 1 (inheritance):

var Turtle1 = root.Doodad.Object.$extend({
    $TYPE_NAME: 'Turtle1',

    talk: root.Doodad.PUBLIC(function() {
        return "Hi !";
    }),
})

var turtle = new Turtle1();

turtle.talk();

var Turtle2 = Turtle1.$extend({
    $TYPE_NAME: 'Turtle2',

    talk: root.Doodad.OVERRIDE(function() {
        return this._super() + " dOOOOdad";
    }),
})

turtle = new Turtle2();

turtle.talk();

Example 2 (interfaces):

var Turtles = root.Doodad.INTERFACE(root.Doodad.Class.$extend({
    $TYPE_NAME: 'Turtles',

    talk: root.Doodad.PUBLIC(root.Doodad.METHOD()),
}));

var Turtle1 = root.Doodad.Object.$extend(
            Turtles,
{
    $TYPE_NAME: 'Turtle1',

    talk: root.Doodad.OVERRIDE(function() {
        return "Hi";
    }),
})

var Turtle2 = root.Doodad.Object.$extend(
            Turtles,
{
    $TYPE_NAME: 'Turtle2',

    talk: root.Doodad.OVERRIDE(function() {
        return "Bonjour";
    }),
})

Example 3 (mix-ins) :

var Turtles = root.Doodad.MIX_IN(root.Doodad.Class.$extend({
    $TYPE_NAME: 'Turtles',

    talk: root.Doodad.PUBLIC(function() {
        return "Hi";
    }),
}));

var Turtle1 = root.Doodad.Object.$extend(
            Turtles,
{
    $TYPE_NAME: 'Turtle1',
})
