Include jQuery as usual inside script tags in index.html.

After all the imports but before declaring @Component, add:
```
declare var $: any;
```
Now you are free to use jQuery anywhere in your Angular 2 TypeScript code:
```
$("#myModal").modal('show');
```

Here is my full implementation of modal bootstrap angular2 component:

I assume that in your main index.html file (with <html> and <body> tags) at the bottom of <body> tag you have:

  <script src="assets/js/jquery-2.1.1.js"></script>
  <script src="assets/js/bootstrap.min.js"></script>

modal.component.ts:

import { Component, Input, Output, ElementRef, EventEmitter, AfterViewInit } from '@angular/core';

declare var $: any;// this is very importnant (to work this line: this.modalEl.modal('show')) - don't do this (becouse this owerride jQuery which was changed by bootstrap, included in main html-body template): let $ = require('../../../../../node_modules/jquery/dist/jquery.min.js');

@Component({
  selector: 'modal',
  templateUrl: './modal.html',
})
export class Modal implements AfterViewInit {

    @Input() title:string;
    @Input() showClose:boolean = true;
    @Output() onClose: EventEmitter<any> = new EventEmitter();

    modalEl = null;
    id: string = uniqueId('modal_');

    constructor(private _rootNode: ElementRef) {}

    open() {
        this.modalEl.modal('show');
    }

    close() {
        this.modalEl.modal('hide');
    }

    closeInternal() { // close modal when click on times button in up-right corner
        this.onClose.next(null); // emit event
        this.close();
    }

    ngAfterViewInit() {
        this.modalEl = $(this._rootNode.nativeElement).find('div.modal');
    }

    has(selector) {
        return $(this._rootNode.nativeElement).find(selector).length;
    }
}

let modal_id: number = 0;
export function uniqueId(prefix: string): string {
    return prefix + ++modal_id;
}

modal.html:

<div class="modal inmodal fade" id="{{modal_id}}" tabindex="-1" role="dialog"  aria-hidden="true" #thisModal>
    <div class="modal-dialog">
        <div class="modal-content">
            <div class="modal-header" [ngClass]="{'hide': !(has('mhead') || title) }">
                <button *ngIf="showClose" type="button" class="close" (click)="closeInternal()"><span aria-hidden="true">&times;</span><span class="sr-only">Close</span></button>
                <ng-content select="mhead"></ng-content>
                <h4 *ngIf='title' class="modal-title">{{ title }}</h4>
            </div>
            <div class="modal-body">
                <ng-content></ng-content>
            </div>

            <div class="modal-footer" [ngClass]="{'hide': !has('mfoot') }" >
                <ng-content select="mfoot"></ng-content>
            </div>
        </div>
    </div>
</div>

And example of usage in client Editor component: client-edit-component.ts:

import { Component } from '@angular/core';
import { ClientService } from './client.service';
import { Modal } from '../common';

@Component({
  selector: 'client-edit',
  directives: [ Modal ],
  templateUrl: './client-edit.html',
  providers: [ ClientService ]
})
export class ClientEdit {

    _modal = null;

    constructor(private _ClientService: ClientService) {}

    bindModal(modal) {this._modal=modal;}

    open(client) {
        this._modal.open();
        console.log({client});
    }

    close() {
        this._modal.close();
    }

}

client-edit.html:

<modal [title]='"Some standard title"' [showClose]='true' (onClose)="close()" #editModal>{{ bindModal(editModal) }}
    <mhead>Som non-standart title</mhead>
    Some contents
    <mfoot><button calss='btn' (click)="close()">Close</button></mfoot>
</modal>

Ofcourse title, showClose, mhead and mfoot ar optional parameters.

For me I had to settimeout in addition to @arjun-sk solution's (link), as I was getting the error
```
setTimeout(() => {
      this.modalService.open(this.loginModal, { centered: true })
    }, 100); 
```

I do not feel there is anything wrong with using JQuery with angular and bootstrap, since it is included when adding bootstrap.
1. Add the $ right after the imports like this
```
import {.......

declare var $: any;

@component.....
```
1. modal should have an id like this
<div id="errorModal" class="modal fade bd-example-modal-lg" tabindex="-1" role="dialog" aria-labelledby="myLargeModalLabel" ..............
1. then have a method like this
showErrorModal() { $("#errorModal").modal('show'); }
1. call the method on a button click or anywhere you wish
