How to import jquery and mCustomScrollbar plugin into Angular2 component

Question

I have a problem with import these modules to my angular2 component. I using angular2-webpack-starter from AngularClass.

I install dependecies with npm:

npm install jquery --save
npm install malihu-custom-scrollbar-plugin --save

and install typings:

typings install jquery --save --ambient
typings install mcustomscrollbar --save --ambient

And i want to use it in component like this:

jQuery('.selector').mCustomScrollbar();

What is the best solution to do that?

I tried to use this solution: Whats the best way to use jquery widgets inside angular 2?

USING
Angular: 2.0.0

Angular-cli: 1.0.0-beta.16
webpack: 2.1.0-beta.22
node: 4.6
npm: 2.15.9

ANSWER
Add types to src/tsconfig.json

SOLUTION

1. Get Required packages
   npm install jquery malihu-custom-scrollbar-plugin --save
npm install @types/jquery @types/jquery-mousewheel @types/mcustomscrollbar --save-dev
   

2. Add plugin css and scripts to angular-cli.json in your root folder

   //angular-cli.json
   "apps": [
       {
           ...,
           "styles": [
               ...,
               "../node_modules/malihu-custom-scrollbar-plugin/jquery.mCustomScrollbar.css"
           ],
           "scripts": [
               "../node_modules/jquery/dist/jquery.js",
               "../node_modules/malihu-custom-scrollbar-plugin/node_modules/jquery-mousewheel/jquery.mousewheel.js",
               "../node_modules/malihu-custom-scrollbar-plugin/jquery.mCustomScrollbar.concat.min.js"
           ],
           ...
       }
   ]
   

3. Add types to src/tsconfig.json

   //tsconfig.json
   {
       "compilerOptions": {
           ...,
           "typeRoots": [
               "../node_modules/@types/"
           ],
           "types": [
               "jquery","jquery-mousewheel","mCustomScrollbar"
           ],
           ...
       }
   }
   

4. Make Directive

   //scrollbar.directive.ts
   import {Directive, ElementRef, OnInit} from '@angular/core';
   declare var $:any;  //<-- let typescript compiler know your referencing a var that was already declared
   
   @Directive({
       selector: 'scrollbar',
       host: {'class':'mCustomScrollbar'},  //<-- Make sure you add the class
   })
   export class ScrollbarDirective implements OnInit {
       el: ElementRef;
       constructor(el:ElementRef) {
           this.el = el;
       }
       ngOnInit() {
           //$(function(){ console.log('Hello'); }); <--TEST JQUERY
           //check if your plugins are loading
           //$().mousewheel) ? console.log('mousewheel loaded') : console.log('mousewheel not loaded');
           //$().mCustomScrollbar) ? console.log('mCustomScrollbar loaded') : console.log('mCustomScrollbar not loaded');
   
           $(this.el.nativeElement).mCustomScrollbar({
               autoHideScrollbar: false,
               theme: "light",
               advanced: {
                   updateOnContentResize: true
               }
       });
   

5. Include directive in ngModule and apply in your component's template

   //app.module.ts
   import {ScrollbarDirective} from "./shared/UI/scrollbar.directive";
   import {AppComponent} from "./app.component";
   
   @NgModule({
   ...
       declarations: [
           AppComponent,
           ...,
           ScrollbarDirective
       ],
   ...
   })
   export class AppModule{}
   

   ---

   //app.component.ts
   @Component({
       selector: 'dashboard',
       templateUrl: `
           <scrollbar>
               <div *ngFor="let thing of things">thing</div><br/>
           </scrollbar>
       `
   })
