Third part libs and Angular Universal [Angular 2]

Question

I am using prism.js in my project and when I switch to universal-cli I get error in terminal from server side

ReferenceError: Prism is not defined

in angular-cli.json I have prism script:

"scripts": [
    "assets/prism.js"
]

And from component I call it like this:

declare var Prism: any;
Prism.highlightAll();

Anyone know how to solve this?
