Connect to Azure AD secured SignalR Hub from your SPFx code
SignalR is a great technology to provide users with real-time UI updates of events happening in the back-end. It’s a perfect match with SPFX to build some amazing web parts for SharePoint. With the recent release of ASPNET SignalR Core (now incorporated in the ASP.NET Core GitHub project) SignalR is easier to use than before. So you’ve gone and created a web part that connects to a SignalR hub and the experience makes a real impact for your users.
