Do we have a J script/class to handle Server-Sent Events (SSE), i.e.
requests from a EventSource class in js? 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!
Any suggestion?
