We completed the post by having a fully functional backend setup with SignalR and authentication done via Resource Owner Password. Today we will see how we can connect to SignalR hub from an Angular application and demonstrate how we can authenticate in five parts: SignalR server Setup an Angular application Connect to SignalR hub Send messages Authentication 1. SignalR server We won’t be describing the server here, instead we will take from where we left in my previous blog post with the code fully available on my Github https://github.com/Kimserey/signalr-core-sample/tree/master/Example . Get the repository and run signalr-core-sample/Example . It will run a server on http://localhost:5000 with a SignalR hub on /chathub and Identity server configured with a client my-app setup with Resource owner password flow. 2. Setup an Angul...

To start we create a HelloWorld applicatio...
