WebSockets and Node.js - testing WS and SockJS by building a web app
SockJS is a library that mimics the native WebSockets API. Additionally, it will fall back to HTTP whenever a WebSocket fails to connect, or if the browser being used doesn’t support WebSockets. Like WS, SockJS requires a server counterpart; its maintainers provide both a JavaScript client library and a Node.js server library.

Top WebSocket libraries for Node.js in 2022
SockJS is a JavaScript library that provides communication between the client and the server in a way similar to the native WebSockets API. SockJS functions with a server counterpart in the form of sockjs-node and SockJS-client, a JavaScript client library.

Socket.IO’s primary use, however, is for facilitating real-time, bidirectional, and event-based communication between the browser and the server. Like ws, Socket.IO has a Node.js server and a JavaScript client library.

We Improved Reliability of Our WebSocket Connections
> Conversely, if the client does not receive a PING packet within `pingInterval + pingTimeout`, it will consider that the connection is closed.
Indeed looks like a solid way to solve the client-side recognition of a broken connection!
--
That said, I'm a little confused because I cannot find any mention of `pingTimeout` in their JS client [0], and `pingInterval` is only mentioned in an implementation of a test server [1]. I wonder if I'm looking at the wrong thing.
