I always recommend looking at Server-Sent Events [0] and EventSource [1]. It's a standardization of old style long-polling, mapping very well to the HTTP paradigm and is built in to the web standard.
It's so much easier to reason about than websockets, and a naive server side implementation is very simple.
A caveat is to only use them with HTTP 2 and/or client side logic to only have one connection open to the server, because of browser limits on simultaneous requests to the same origin.
