Abstract

The growth in demand for real-time communication in web applications on the Internet has driven the emergence of the WebSocket protocol. This is a network protocol used for this type of communication, creating a persistent connection between client and server. Introduced in 2011, WebSocket stands out among other approaches used on the internet for delivering real-time data, such as SSE and HTTP Long Polling, due to its flexibility in data traffic and its bidirectional connection. Companies like Tinder and Dropbox use WebSocket technology in their applications to handle real-time traffic and enable functionalities that require this characteristic. The objective of this work is to create an online auction application, based on a client-server architecture, where interaction and instant responses are essential during the bidding process. Using the WebSocket protocol to deliver bids and ensure smoothness, providing a satisfying user experience for the end user.
