The ASP.NET Core SignalR library is open source and allows developers to simplify adding real-time web functionality to applications. This means that the server-side code can instantly push content to connected clients. In Real-Time ASP.NET Core 3 Apps with SignalR Succinctly, Dirk Strauss will show you how to use it to create a chat application with minimal code and how to modify that same code to create a chart application. Just by changing a few lines of code, you can automatically pull data via an API call and update your page in real time.
