How can WebSockets enable real-time features in web apps?

Asked on Nov 09, 2025

Answer

WebSockets provide a full-duplex communication channel over a single TCP connection, enabling real-time data exchange between the client and server. This is particularly useful for applications requiring instant updates, such as chat applications, live notifications, or collaborative tools.

Example Concept: WebSockets establish a persistent connection between the client and server, allowing data to be sent and received simultaneously. Unlike HTTP, which is request-response based, WebSockets maintain an open channel, reducing latency and overhead by eliminating the need for repeated handshakes. This makes WebSockets ideal for real-time applications where low latency and efficient data transfer are critical.

Additional Comment:

WebSockets are supported by most modern browsers and can be implemented using libraries like Socket.IO for easier integration.
They are particularly beneficial in scenarios where frequent updates are necessary, such as stock tickers or multiplayer games.
Security considerations include using WSS (WebSocket Secure) to encrypt data over the connection.
