WebSocket

WebSocket is a bi-directional communication protocol that enables real-time, full-duplex data transfer between a client (browser) and a server over a single TCP connection. Unlike traditional HTTP requests, which require constant polling to update data, WebSocket maintains an open connection, reducing network overhead and latency. This makes it ideal for applications requiring instant updates and low-latency communication, such as live chat, real-time notifications, multiplayer games, and financial market updates.

Key Features

• Full-Duplex Communication – Enables simultaneous data exchange between client and server.

• Persistent Connection – Keeps the connection open for continuous interaction.

• Low Latency – Reduces the need for frequent HTTP requests.

• Efficient Bandwidth Usage – Uses a single connection instead of multiple requests.

• Event-Driven Architecture – Allows real-time updates without additional request cycles.

• Cross-Platform Support – Works with browsers, mobile apps, and backend servers.

Best Use Cases

✔️ Live Chat Applications – Messaging platforms like WhatsApp, Slack, and Discord.
✔️ Real-Time Collaboration – Google Docs, Trello, and online whiteboards.
✔️ Stock Market & Trading Platforms – Real-time updates for financial data.
✔️ Online Gaming – Multiplayer game synchronization and low-latency interactions.
✔️ IoT & Smart Devices – Enabling seamless device communication.
