Socket.io store that connects to Windows Azure Service Bus
This project provides a Node.js package that lets you use Windows Azure Service Bus as a back-end communications channel for socket.io applications.
Fixes to the presence system in the chat application. Not 100% there, but working much better in the multi-server case.
Service Bus topics and subscriptions are now created automatically if they don't already exist. Subscriptions are created with a five minute idle expiration time, so they won't stick around once the server is no longer polling them.
The cross-server presence indicators in the chat sample has been updated to properly handle the multi-server environment.
There's the start of a perf test harness in examples/timingtest.
To get the source code of the SDK via git just type:
git clone https://github.com/WindowsAzure/socket.io-servicebus cd ./socket.io-servicebus
You can install the azure npm package directly.
npm install socket.io-servicebus
First, set up your Service Bus namespace. You will need a shared topic name; this can either be created in advance or the module will create them for you.
These can be created either via the Windows Azure portal or programmatically using the Windows Azure SDK for Node.
Then, configure socket.io to use the Service Bus Store:
var sio = ;var SbStore = ;var io = sio;io;
The connection string can either be retrieved from the portal, or using our powershell / x-plat CLI tools. From here, communications to and from the server will get routed over Service Bus.
The current version (0.0.2) only routes messages; client connection state is stored in memory in the server instance. Clients need to consistently connect to the same server instance to avoid losing their session state.
