Hey Kevin, first thank you for this great repo. There's lot of good stuff in here ;)

I have been using the SignalR hub and I was having issues getting the client IDas it was undefined.

My code looked like this:

signalRHub.initHub(hubCallbacks);

    function hubCallbacks(hub) {
        hub.start();

        var id = hub.clientId; //this id is always undefined
    }

To make it work I had to return the call to the start method in the hub:

start: function () {

                    if ($.connection.hub.state !== $.connection.connectionState.disconnected) {                
                        $.connection.hub.stop(true, true)
                    }
                    return $.connection.hub.start(); //returns the promise here
                }

So then I could use it like this:

  hub.start().done(function () {
            clientId = $.connection.hub.id; //this clientId is correct
        });

Hello.
I am still working with version 8 of Umbraco and I downloaded the project because it seems to me an excellent starting point for a new feature that I have to implement in my site (custom tables in the database).
Unfortunately the site does not work and goes into error wherever it shows an image:

which are mandatory and which I cannot replace.

I saw that the Media folder is empty in GitHub as well. So the Products and People tabs don't work.

Is it possible to have pictures or a workaround so that you can debug the code and understand how it works?

I have developed

https://www.consap.it/

and I would like to collaborate with you and help others with Umbraco 8. If you are interested let me know.

This repo is a good place to add example snippets of how to do things in Umbraco v8 (mainly back office at the moment).

If you want to contribute - then

1. Raise an issue for the thing you want to add.
2. add it
3. submit the PR.

All contributions welcome.
