SignalR Message Pack Client Library not running in browser when using Angular Cli

[QuinntyneBrown]

After importing MessagePackHubProtocol from @aspnet/signalr-protocol-msgpack inside of an Angular app using the Angular cli, the application will no longer run in the browser.

You will see the following exception in the console.

Steps to reproduce the behavior:

Clone and run the following app:
https://github.com/QuinntyneBrown/ng-signalr-protocol-msgpack-issue

or

1. Create an angular app using the angular cli

2. npm install @aspnet/signalr and @aspnet/signalr-protocol-msgpack

3. In the app component, import HubConnectionBuilder from @aspnet/signalr

4. In the app component, import MessagePackHubProtocolfrom @aspnet/signalr-protocol-msgpack

5. In the app component, add a method called ngOnInit

6. Inside the ngOnInit method, add the following code

   var connection = new HubConnectionBuilder()
   .withUrl("")
   .withHubProtocol(new MessagePackHubProtocol())
   .build();

7. run the app with the console open, and you should see the error. The UI will be blank.

Expected behavior

You should see the standard angular cli default page.

Thanks,

Thanks @alan-agius4

I added the following line to the bottom of polyfills.ts

(window as any).global = window;

I'm getting the following error when I run the app.

Should I create another issue?
