FlashSocket.IO

Flash library to facilitate communication between Flex applications and Socket.IO servers.

The actual websocket communication is taken care of by my fork of gimite/web-socket-js project.

This project wraps that and facilitates the hearbeat and en/decoding of messages so they work with Socket.IO servers

Checkout

Because this project makes use of git submodules you must make use of the recursive clone.

git clone --recursive git://github.com/simb/FlashSocket.IO.git

Building

Because this library is dependent on the websocket library, you must add the support/websocket-js path to you source path in flash builder or your build files.

Usage

For Socket.io 0.7 and 0.8 you will need to use the Beta swc that you can find in the downloads section. Currently in beta.

An example of a flex application connecting to a server on localhost is below
