WebSocket Protocol Fundamentals
Understand the WebSocket protocol and its advantages for bidirectional, real-time communication.
Welcome to WebSockets!
Modern web applications often need instant updates and real-time interactions. Think of live chats, multiplayer games, or collaborative editing tools.
Traditional HTTP wasn't designed for this. That's where WebSockets come in!
In this lesson, you'll learn what WebSockets are and why they're crucial for building dynamic, real-time features.
HTTP: Request-Response Cycle
HTTP (Hypertext Transfer Protocol) works on a simple request-response model:
- The client sends a request.
- The server sends a response.
Once the response is sent, the connection closes. This is efficient for fetching static content, but not for continuous, instant data exchange.
