Integrating NodeJs modules into the Editor
Integrating Custom modules into the Content Editor
The Scripts environment gives you the ability to have custom elements on your server inside the content editor.
The icon image mentioned in the Creating own nodejs modules article will show up in the editor as the element's icon. The place holder image will show once the element is placed onto the canvas.
The custom widgets and the displayed communicated over messages. You see examples of this technique in our sample custom widget.
