A WebSocket is a technology that enables real-time communication between a web browser and a web server.
Unlike traditional web interactions, where the browser sends a request and the server responds, WebSockets allow the browser and server to exchange data simultaneously through a continuous, two-way connection.
With regular web requests, the browser connects to the server, gets the response, and then disconnects.
But with WebSockets, the connection remains open, allowing for ongoing communication without the need to establish new connections repeatedly.
Features of WebSocket
1. Real-Time Interaction
WebSockets are used in web applications that require instant, back-and-forth communication.
For example, in a chat application, when you send a message, it appears on the recipient’s screen almost instantly.
2. Low Latency
This technology is all about reducing delays.
WebSockets are ideal for applications where speed matters, like online games, live sports scores, or stock market updates.
3. Efficient and Lightweight
They are designed to be efficient and use less data than traditional methods.
This efficiency is important for mobile devices and can save bandwidth and improve performance.
4. Security
WebSockets can be secured with encryption, just like the padlock symbol you see in your web browser for secure websites.
This ensures that the data being exchanged is protected from eavesdropping.
5. Versatile
WebSockets are used in various applications, from real-time chats and notifications to collaborative tools and live streaming.
They add interactivity and real-time features to websites and apps.
6. Cross-Platform
Most modern web browsers support WebSockets, making them accessible across different devices and operating systems.
In a nutshell, WebSockets are the technology behind real-time, interactive features in web applications, offering low latency, efficient communication, and cross-platform compatibility.
They allow your browser to instantly receive and send data, creating a seamless and dynamic user experience.
