Years of bad reputation of browsers and standards have made us believe that everything needs to be done using JavaScript and lots of different libraries. They have their merits, but the web also didn't stop evolving. Let's take a look at some nifty things browsers offer out-of-the-box we send tons of code down the wire for right now.

In the evolving landscape of web development, real-time data streaming has been dominated by Websockets. However, Server-Sent Events (SSE) offer a compelling alternative, especially for unidirectional communication scenarios. This technical talk will delve into the mechanics of SSE, highlighting its benefits over traditional Websocket in terms of simplicity and efficiency in handling real-time data flows. I will provide a walkthrough of implementing SSE in a robust web application using .NET as the backend framework and React for the frontend development. The session will include a practical demonstration of setting up SSE for streaming updates to a web UI. Additionally, the talk will briefly explore the OpenAI ChatGPT API as a case study to illustrate the practical applications of SSE in live projects. Attendees will leave with a solid understanding of when and how to effectively employ SSE in their projects, enhancing their toolkit for web UI development. This presentation is aimed at developers and architects seeking to enrich their real-time interaction capabilities without the overhead complexity of Websockets.
