...SockJS gives you a coherent, cross-browser, Javascript API which creates a low latency, full duplex, cross-domain communication channel between the browser and the web server, with WebSockets or without. This necessitates the use of a server, which this is one version of, for Node.js.
This project offers a python binding to the libindi library. It uses the Simplified Wrapper and Interface Generator (SWIG). You may generate a PyIndi module which mainly defines an IndiClient class. This class could be used to build python scripts able to interact with indi servers using sendNew* methods and implementing new* methods of the BaseMediator class. PyQt applications may also be built on top of IndiClient, thus allowing rapid development of GUI Indi clients.
Besides Python there...
JAVA websocket implementation for a bomberman-like game
This application uses JAVA and Glassfish server to provide an active and simple webSocket server for an online, multiplayer bomberman-like game.
It only requires a running glassfish server to deploy the application on and a MySQL database server.
After deployment and first run, anyone can access your webserver, register and play the game, using only a web browser that has built-in support for webSockets
