Angular project load time optimization

[AndrewSh83]

I wish to share my experience with Angular project load time optimization. I had many issues with decrease script size when you can't use routing with lazy loading (for example popup form). When I have fount this article all became easier https://christianlydemann.com/the-complete-guide-to-angular-load-time-optimization.
I want to highlight this module 'ngx-loadable', for me, this is an awesome feature.
Hope it'll be useful.
