SockJS features and specs

Cross-browser Compatibility
SockJS provides a consistent WebSocket-like API that works across all modern browsers, including fallback options for older browsers that don't support WebSockets.
Fallback Options
SockJS automatically uses the best-available transport method, such as JSONP, XHR streaming, or XHR polling, ensuring connectivity even in challenging network environments.
Reliability
By offering multiple transport methods, SockJS provides reliable real-time communication even when WebSocket connections might be unstable or unsupported.
Ease of Use
SockJS abstracts the complexity of managing various transport protocols, allowing developers to focus on implementing application logic rather than handling connection details.
Server Support
SockJS is supported by several server-side implementations in different programming languages, enabling flexibility in choosing backend technologies.

Possible disadvantages of SockJS

Overhead
The additional abstraction layer and fallback mechanisms may introduce some overhead compared to using native WebSockets directly, impacting performance to some extent.
Configuration Complexity
Setting up SockJS with proper fallback handling and configuring the server-side components might be more complex than using native WebSockets, especially for simple use cases.
Less Control
Developers have less control over the specific transport protocols being used, which might be a disadvantage in scenarios where such control is necessary for optimization or monitoring purposes.
Potential Latency
Using fallback transports like polling can introduce higher latency compared to native WebSocket connections, which might not be suitable for highly time-sensitive applications.
Project Maintenance
As an open-source project, SockJS relies on community support for maintenance and updates. This could pose a risk if development and support decline over time.

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. - Source: dev.to / over 1 year ago
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. - Source: dev.to / over 3 years ago
