Is it possible to use Bootstrap with the latest version of Angular like 5/6/7?

The answer is Yes! can easy use Bootstrap in out Angular project in the latest version like 4/5/6/7. Here we will discuss on how to install Bootstrap quickly and How to use its beautifully crafted plug/play components in the application.

Installing Bootstrap

Installing via NPM, run following npm command to install ng-bootstrap package

$ npm install --save @ng-bootstrap/ng-bootstrap

Next, open app.module.ts then import NgbModule then add in imports array also add HttpClientModule as we will make HTTP calls to IMDB API

import {NgbModule} from '@ng-bootstrap/ng-bootstrap';
import { HttpClientModule } from '@angular/common/http';
  imports: [NgbModule,HttpClientModule ...],
export class AppModule {

Here we will test Bootstrap's most loved and used Auto suggestion component known as Typeahead.

In Home component, we will add an Input bar from where a user can search IMDB movies using HTTP get call to public API.

In file add the following code

import { Component, OnInit, ViewChild, ElementRef } from '@angular/core';
import { Observable, Subject, merge, of } from 'rxjs';
import { debounceTime, map, distinctUntilChanged, filter, switchMap, catchError } from 'rxjs/operators';
import { HttpClient, HttpParams } from '@angular/common/http';
import { NgbTypeahead } from '@ng-bootstrap/ng-bootstrap';

const APIKEY = "e8067bXX";

const PARAMS = new HttpParams({
  fromObject: {
    action: 'opensearch',
    format: 'json',
    origin: '*'

  selector: 'app-home',
  templateUrl: './home.component.html',
  styleUrls: ['./home.component.css']
export class HomeComponent {

  @ViewChild('movieSearch') movieSearch: NgbTypeahead;
  focus$ = new Subject<string>();
  click$ = new Subject<string>();

  searchTermModel: any;

    private httpClient: HttpClient
  ) {

  search = (text$: Observable<string>) =>
      switchMap(term =>
          catchError(() => {
            return of([]);

  searchGetCall(term: string) {

    if (term === '') {
      return of([]);
    return this.httpClient.get('' + term + '&apikey=' + APIKEY,{params: PARAMS.set('search', term)})
      map((response) => {
        return response['Search'];




In add follow

        <ng-template #rt let-r="result" let-t="term">
          <img [src]="r.Poster" class="mr-1" style="width: 80px">
          <ngb-highlight [result]="r.Title" [term]="searchTermModel"></ngb-highlight>

        <div class="form-group">
          <label for="typeahead-http">Search Movies By Name:</label>
          <input id="typeahead-http" type="text" class="form-control"  placeholder="IMDB search" 
          [resultTemplate]="rt" />

Here we used [resultTemplate] to modify suggestions for IMDB result set. You can check more options and details here
