In this week’s newsletter, let me introduce you to SignalR and how we can integrate and work with SignalR from an ASP.NET Core application.

For starters, ASP.NET Core SignalR is an open-source library that simplifies adding real-time web functionality to apps. Real-time web functionality enables server-side code to push content to clients instantly.

It supports the following techniques for Realtime data transmission:

• WebSockets

• Server-Sent Events

• Long Polling

It automatically chooses the best transport method that is within the capabilities of the server and client.

Integrating with ASP.NET Core

ASP.NET Core provides a very good integration with SignalR, it comes within the default AspNetCore.App package. In SignalR, you define Hubs - you think of them as a pipeline which allow client-server interaction.

The methods defined inside the Hubs can be called (or invoked) by the connected client, and the server can send data to the clients. We register SignalR as a service and then register the Hubs inside the Endpoint middleware. The Endpoint middleware also handles calls to the SignalR along with the API controller calls.

SignalR Client libraries are available for almost all languages and frameworks. You can pick the appropriate client package for your application and communicate with the Server side Hubs.
