How use js library with jquery on angular2 (typescript)?

Question

I try migrate angular js to angularjs2 with typescript.

I can't understand how use js library. I have main app.component where I want initialize some library, for example simple row:

$('#home').height($(window).height());

and initialize by attribute data-spy="scroll" data-target="#header-navbar" data-offset="51"

Index.html

<body data-spy="scroll" data-target="#header-navbar" data-offset="51" class="pace-done">

    <pm-app>Loading App...</pm-app>

        System.import('app/main')
            .then(null, console.error.bind(console));
    </script>

</body>

general main.ts

import { bootstrap }    from 'angular2/platform/browser';

// Our main component
import { AppComponent } from './app.component';

bootstrap(AppComponent);

and empty app.component.

simply put your logic in the constructor of your class.Have you tried yet ? and `declare var $=any` — Pardeep Jain, Jul 24 '16 at 18:32

In order to use jQuery you firstly you have to import in the index.html, than you can initialize your code in the constructor of component

constructor(){
   .....
   $('#home').height($(window).height());
}

in case IDE shows error than you can declare $ of any type at the top of the class like this :-

...some  code here 
declare var $ : any;

export class App{
..///code goes here
}
