Angular Universal error

Describe the bug I am seeing an issue with running angular-calendar using Universal/SSR. The specific issue is one step lower with the angular-draggable-droppable package where it is failing to find a definition for window, which is to be expected on Universal.

Minimal reproduction of the problem with instructions N/A Applies to Universal only, not sure that I can do a Stackblitz with universal.

Screenshots `/Users/User/Projects/project/website/node_modules/angular-draggable-droppable/bundles/angular-draggable-droppable.umd.js:118 for (var i = 0, limit = prefix.length; i < limit && !window.requestAnimationFrame; ++i) { ^

@anishchcenko you need to add these 2 lines to the top of the server.ts file for it to work: https://github.com/mattlewis92/angular-calendar#is-this-library-aot-and-universal-compatible

It works!

Hi @mattlewis92, thank you a lot. The fix works. I am able to render calendar with SSR.
