WebSockets
Explore the WebSocket protocol to understand how it enables efficient, bidirectional, real-time communication between client and server. Learn about its structure, use cases like chat and gaming, benefits such as low latency and scalability, and when to avoid its use.
Overview
WebSocket is a protocol for real-time, bidirectional communication between a client and a server over a single, long-lived connection. It allows for low-latency, bidirectional communication and is widely used for real-time applications such as online gaming, chat applications, and financial trading platforms.
Structure of a WebSocket
A WebSocket connection is established using the WebSocket handshake, which is a standard HTTP upgrade request. Once the connection is established, both the client and server can send messages to each other without the need for a new request-response cycle. The messages are sent as binary or text data and can be compressed to reduce the amount of data sent over the network.
Communication
WebSocket uses a publish-subscribe pattern for communication, where the client can subscribe to a specific channel or ...
