CoffeeScript minimalist interface to express, and others

Zappa is a CoffeeScript-optimized interface to Express and Socket.IO.

Major improvements in Socket.IO interface:

Now supports saving the Session object in Socket.IO methods. Session content can be modified both from ExpressJS and from Socket.IO.

Supports ack callback for all Socket.IO emit calls.

The ZappaJS client is no longer embedded and was moved to a separate module, zappajs-client.

Sammy and jQuery are no longer embedded:

  • As a consequence the zappa middleware is no longer required and was removed. If your code references any Javascript file under /zappa/, consider using e.g. browserify-middleware to build the dependencies.
  • Also, @client and @shared are gone (along with their magic).

Client-side code is now bundled using browserify-string; @browserify replaces @client, while @isomorph replaces @shared.

Now uses the debug module instead of logging to console directly.

Host and port might be specified using the ZAPPA_PORT and ZAPPA_HOST environment variables, which are used as default if no explicit configuration is provided.
