Has anyone worked with esri-loader and have implemented successfully?

I am looking at the cli example (https://github.com/tomwayson/esri-angular-cli-example) listed on the esri-loader site (https://github.com/Esri/esri-loader) and it is still using the old libraries.

Is there a lot of difference in terms of how it is implemented in various files shown here in this link https://gist.github.com/tomwayson/e6260adfd56c2529313936528b8adacd?

Thanks!
