WebSockets are a connection-based communication protocol that enables full-duplex real-time communication, providing a modern alternative to the traditional RESTful pattern. Unlike REST, which operates on a synchronous request-response mechanism, WebSockets allow for asynchronous message-based communication, which is particularly useful for applications requiring frequent updates, such as multiplayer games or chat services. The article uses a Connect4-style demo app to illustrate how WebSockets can be implemented, showcasing a Node.js server using Socket.io and a React client communicating over WebSockets. The server manages the game state, ensuring players make valid moves, while the client updates the board and displays messages based on server communications. This approach eliminates issues associated with REST, such as HTTP polling lag and excessive server requests, by enabling real-time updates and efficient client-server interaction. Through this example, the article highlights the advantages of using WebSockets for developing interactive, real-time web applications.
