Is it possible to use npm packages like rellax on hubspot?

I just wanted to know if it is possible to use npm packages like rellax on hubspot. If it is possible, how do you do it?

@IMckell yes you can! 

In this specific example you could easily add the library to your code using CDN and then implement it without issues.

I used libreries like this in some pages and had no issues so far!

Is there a way to do this without a CDN? It seems like a CDN can grow disorganized and make it easy to forget about updates.
