node-bus

node-bus is a project where the goal is to provide a really simple facility for pubsub-style eventing between clients and a central server.

The bus framework includes a client-side javascript tool which handles all of the comet requests to make the developer's job as easy as possible. (automatically degrades from WebSockets to long polling)

Setting Things Up

Ensure that you have socket.io:

npm install socket.io

Download the node-bus repository:

git clone git@github.com:node-bus/node-bus.git --recursive
cd node-bus
git submodule update --init --recursive

Then run the build:

ant

Running the Test Server

Run the server:

cd apps
node server.js

Then, navigate a browser to http://localhost:8080/
