Ng Bootstrap is developed from bootstrap and they provide all bootstrap 3 and bootstrap 4 native Angular directives like model, tooltip, pagination, datepicker, buttons etc. Ng Bootstrap will help to easily use bootstrap ui.

So, let's follow this tutorial step by step.

Step 1: Create New App

You can easily create your angular app using bellow command:

ng new my-new-app

Step 2: Install Bootstrap 4

In this step, we will install bootstrap core package. so we can use bootstrap css so let's install by following command:

npm install bootstrap --save

Now, we need to include bootstrap css like "node_modules/bootstrap/dist/css/bootstrap.min.css", so let's add it on angular.json file.



"styles": [





Step 3: Install Ng Bootstrap

In this step, we will install Ng Bootstrap package. so we can use bootstrap ui so let's install by following command:

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

Step 4: Import Module

In this step, we need to import NgbModule to app.module.ts file. so let's import it as like bellow:


import { BrowserModule } from '@angular/platform-browser';

import { NgModule } from '@angular/core';

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

import {NgbModule} from '@ng-bootstrap/ng-bootstrap';


declarations: [



imports: [




providers: [],

bootstrap: [AppComponent]


export class AppModule { }

Step 5: Updated View File

so let's put bellow code:


<h1>Angular 8 Bootstrap 4 Tooltip Example -</h1>

<button type="button" class="btn btn-outline-secondary mr-2" placement="top" ngbTooltip="Tooltip on top">
