This page demonstrates how Mongoose web server could be used to implement

|
|
|
|
<a href="http://en.wikipedia.org/wiki/Publish%E2%80%93subscribe_pattern">
|
|
|
|
|
|
publish–subscribe pattern</a>. Open this page in several browser
|
|
|
|
|
|
windows. Each window initiates persistent
|
|
|
|
|
|
<a href="http://en.wikipedia.org/wiki/WebSocket">WebSocket</a>
|
|
|
|
|
|
connection with Mongoose, making each browser window a websocket client.
|
|
|
|
|
|
Join a room, send messages, and see messages sent by other clients.
