SignalR is a real-time web framework for building interactive and high-performance web applications. It allows bi-directional communication between the client and the server in real-time, enabling you to push data from the server to the client as soon as it’s available, and vice versa.

SignalR provides an abstraction over the underlying communication protocols, such as WebSockets, Server-Sent Events (SSE), and long-polling, to provide a unified API for building real-time web applications. This means that you can write your application logic using a simple API, and let SignalR handle the details of choosing the most appropriate communication protocol based on the client’s capabilities and the server’s configuration.

SignalR is available for a wide range of platforms, including .NET, JavaScript, Java, and Python. It also integrates seamlessly with popular web frameworks, such as ASP.NET and ASP.NET Core.

Overall, SignalR is a powerful tool for building real-time web applications that require high-performance and interactivity, such as chat applications, multiplayer games, and real-time dashboards.

To establish this connection, the client needs to know the URL of the SignalR hub and the security token to authorize…
