A demo of a TODO app using four spinners created for the blog post: https://christianlydemann.com/four-ways-to-create-loading-spinners-in-an-angular-app/
Doesn't build out of the box.
Running:
npm 8.4.1
node v16.13.2
Angular CLI: 13.2.2
I don't expect you will fix it, but this issue is here in case you ever come back to it :)
Incidentally I found your repo because I was looking for working HTML and CSS to provide an angular component that could give a 'spinner' over the top of its content.
For now I'm trying to just copy your components into my project and see if it works.
Thanks.
