You can use Socket.IO or SocketCluster.

Socket.IO works for simple Express apps - you just attach it, like any other 
middleware.

SocketCluster lets you run multiple processes. That means, if you need to use 
multiple cores for your server, for instance, i would recommend using SC.

Both solutions are "real time engines".
