Server-Sent Events: the alternative to WebSockets you should be using
My personal WebSockets vs SSE TL;DR goes something like this:
* If you're on HTTP/2, start with SSE
* If you need to send binary data, use WebSockets
* If you need fast bidi streaming, use WebSockets
* If you need backpressure and multiplexing for WebSockets, use RSocket or omnistreams[1] (one of my projects).

The WebSocket Handbook
I built omnistreams[0] primarily because of the lack of backpressure in browser WebSockets (lots of background information in that README). It's what fibridge[1] is built on. We've been using it in production for over 2 years, but I never ended up trying to push omnistreams as a thing. I believe the Rust implementation is actually behind the spec a bit, and the spec itself probably needs some work.
At the end of the day I think RSocket is probably the way to go for most people, though the simplicity of omnistreams is still appealing to me.

Woe be onto you for using a WebSocket
A few years ago I was more inclined to use WebSockets. They're undeniably cool. But as implemented in browsers (thanks to the asynchronous nature of JavaScript) they offer no mechanism for backpressure, and it's pretty trivial to freeze both Chrome and Firefox sending in a loop if you have a fast upload connection.
I designed a small protocol[0] to solve this (and a few other handy features) which we use at work[1]. A more robust option to solve similar problems is RSocket[3].
More recently I've been working on a reverse proxy[2], and realized how much of a special case WebSockets is to implement. Maybe I'm just lazy and don't want to implement WS in boringproxy, but these days I advocate using plain HTTP whenever you can get away with it. Server Sent Events on HTTP/1.1 is hamstrung by the browser connection limit, but HTTP/2 solves this, and HTTP/3 solves HTTP/2's head of line blocking problems.
Also, as mentioned in the article, I try to prefer polling. This was discussed recently on HN[4].
