SockJS Web Sockets

#What is SockJS?

SockJS is a client-side JavaScript library that provides a WebSocket-like object for browsers that do not support the WebSocket protocol. It is built to provide a low-latency, full-duplex communication channel between the browser and the web server.

#SockJS Key Features

Most recognizable SockJS features include:

• Provides fallbacks for browsers that don’t support WebSocket.
• Offers various transports such as xhr-streaming, xhr-polling, and iframe-based transports for reliable communication.
• Supports streaming and polling based transports to improve compatibility with various environments.
• Can be used with any web server that supports the WebSocket protocol.
• Provides WebSocket-like APIs to make communication between client and server easier.
• Supports message fragmentation and reassembly.

#SockJS Use-Cases

Some of the SockJS use-cases are:

• Real-time applications such as chat applications, online gaming, and collaborative editing.
• Websites with slow or unreliable networks that require fallback mechanisms.
• Applications that need to establish a low-latency, full-duplex communication channel between the client and the server.
• Projects that require WebSocket-like functionality in browsers that do not support the WebSocket protocol.

#SockJS Summary
