SignalR Overview
Get to know how SignalR can help build responsive interactive apps.
We'll cover the following...
SignalR is a .NET library for building interactive web applications that enable two-way communication between the server and clients. It simplifies the process of adding real-time web functionality to applications by handling the low-level details of managing connections between clients and servers.
By using SignalR, developers can create applications that enable server-side code to push content to connected clients instantly as events occur, rather than relying on the traditional request-response model. It supports various transports, including WebSockets, Server-Sent Events (SSE), and Long Polling.
SignalR can be used in a variety of scenarios, such as chat applications, real-time dashboards, live data updates, collaborative editing, gaming applications, and more. It's a powerful tool for creating interactive, real-time experiences on the web.
SignalR project structure
The following playground contains an application with both the SignalR server and client components:
using Microsoft.AspNetCore.SignalR;
namespace DemoApp;
public class DemoHub : Hub
{
public async Task BroadcastMessage(string message)
{
await Clients.All.SendAsync("ReceiveMessage", message);
}
}If we launch this application, here is what we will see on the home page once it is built:
We can type a message in the text box that is delivered ...
