Look inside

SignalR is an ASP.NET Core library that adds real-time web functionality to your apps, enabling server-side code to instantly communicate with your client. It’s an ideal library for facilitating the lightning-fast communication needed for a real-world Internet of Things project.

In this liveProject, you’ll put SignalR into action to build and implement an airport PA system across the Internet of Things. Your challenge will include creating both the server-side web application using ASP.NET Core with JavaScript front-end and the distributed application that will be deployed on the IoT devices on the ground using .NET Core and Docker. You’ll establish your SignalR setup, enable the transfer of real-time audio data, and enable your IoT applications to both run as a single cluster and deploy on Docker.

This project is designed for learning purposes and is not a complete, production-ready application or solution.

  • Visual Studio or Visual Studio Code, min. version 2019
  • Command line interface

you will learn

In this liveProject, you’ll master SignalR for writing applications that can communicate with each other in real time over a network.

  • Building a server-side SignalR hub and adding various types of endpoints to it
  • Building a .NET-based client application capable of talking to SignalR hub
  • Building a JavaScript-based client application capable of talking to SignalR hub
  • Enabling audio playback on both Windows and Linux
  • Enabling the transfer of audio data via SignalR between the server and the client
  • Enabling multiple instances of IoT applications to run simultaneously as a single IoT cluster
  • Making the deployment of IoT applications easy by using Docker
