In its present state, this project is little more than a proof of concept, though it does contain one usable widget (TreeView).

First, obtain the package via npm install gpc-ko-widgets.

GPC-KO-Widgets is built for consumption via browserify. Browserify not only handles module imports, but CSS injection as well by making use of the excellent cssify transform.

First off, your code will of course need knockout, as well as its plugin knockout-mapping:

var ko = require('knockout');
var ko.mappings = require('knockout.mappings');

To be able to use a widget, your code must also import the module implementing its view model:

var TreeView = require('gpc-ko-widgets/treeview');

Instantiating a widget is a matter of using Knockout's template binding, like so:

div(data-bind="template: { name: 'gktvTreeView', data: myTreeview }")

... and providing a TreeView object as part of your Knockout view-model:

var myTree = {
    'Item 1': {},
    'Item 2': {
        'Subitem 2.1': {},
        'Subitem 2.2': {},
    },
    'Item 3': {}
};

var myViewModel = { 
    myTreeview: new gpc.kowidgets.TreeView( ko.mapping.fromJS(myTree) ),
};

/* Called from body.onload (or as part of jQuery "ready" function) */
window.start = function() {
    ko.applyBindings(myViewModel);
}

And that's it! Thanks to Browserify and friends, you don't have to worry about copying CSS files and referencing them from your HTML.

There is quite a bit more to say about this project, but I'm out time at the moment. Stay tuned for an explanation of how GPC-KO-Widgets leverages both Jade and Knockout templates, and how it uses actual data models on top of Knockout's usual view models.
