Which addon or script are you referring to?

That class is the client side of a Subscribe/Publish model using the browser. It appears we do not. The websocket.ijs script is for the WebSockets transport layer, a full-duplex protocol. AFAICT the script is oriented towards implementing a J server to handle requests from the client. What I need is a way for the server to push info (state, alarm, exception) to the client. In this day of IOT, isn't it a common need? The websocket script is not easy to follow. Would it be possible to modify it (or make a derivative) to make a server push model? Probably. I used Demo 2 and modified it in the normal way, but my attempts at server pushes revealed that the script is not designed for that (I think). Implementing a SSE class would be ideal. The wiki has a page for library requests. It is empty!
