Package Exports

nowpad

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (nowpad) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

NowPad: Realtime Text Collaboration

NowPad adds realtime text collaboration to parts of your website such as textareas, allowing multiple people to work on the same document at the same time (while seeing each others changes as they are applied). The benefit of this over traditional collaborative editing is two people would be editing the same document, they've both made changes, one person saves, and the other has to make the choice "lose my changes, or lose his changes". Nowpad keeps and applies both your changes as they happen.

It Uses

Node.js - Server Side Javascript
Express.js - The "Server" in Server Side Javascript
Now.js - Server and Client Side Communication
CoffeeScript - JavaScript Made Easy
