Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Server-Sent Events: the alternative to WebSockets you should be using
the biggest drawback with SSE, even when unidirectional comm is sufficient is
> SSE is subject to limitation with regards to the maximum number of open connections. This can be especially painful when opening various tabs as the limit is per browser and set to a very low number (6).

also, for websockets, there are various libs that handle auto-reconnnects, e.g. https://github.com/github/stable-socket

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).

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].
