#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
SockJS is a client-side JavaScript library that provides a WebSocket-like object for browsers that do not support the WebSocket protocol.
