Ng Bootstrap is developed from bootstrap and they provide all bootstrap 3 and bootstrap 4 native Angular 10 directives like model, pagination, datepicker, buttons etc. Ng Bootstrap will help to easily use bootstrap ui.

Angular 10 Bootstrap Modal Example

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

Now here, we will updated our html file. we will create simple bootstrap model template file.

so let’s put bellow code:


<h1>Angular 10 Bootstrap Modal Popup Example</h1>

<button class="btn btn-lg btn-outline-primary" (click)="open(mymodal)">Open My Modal</button>

<ng-template #mymodal let-modal>

<div class="modal-header">

<h4 class="modal-title" id="modal-basic-title">Bootstrap Modal</h4>

<button type="button" class="close" aria-label="Close" (click)="modal.dismiss('Cross click')">

<span aria-hidden="true">×</span>



<div class="modal-body">

This is example from


<div class="modal-footer">

<button type="button" class="btn btn-outline-dark" (click)="modal.close('Save click')">Ok</button>



Step 4: Use Component ts File

Now we need to update our component.ts file here we will write code of bootstrap model open and close function so, let’s update as like bellow:


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

import {NgbModal, ModalDismissReasons} from '@ng-bootstrap/ng-bootstrap';


selector: 'app-root',

templateUrl: './app.component.html',

styleUrls: ['./app.component.css']


export class AppComponent {

title = 'appBootstrap';

closeResult: string;

constructor(private modalService: NgbModal) {}

open(content) {, {ariaLabelledBy: 'modal-basic-title'}).result.then((result) => {

this.closeResult = `Closed with: ${result}`;

}, (reason) => {

this.closeResult = `Dismissed ${this.getDismissReason(reason)}`;



private getDismissReason(reason: any): string {

if (reason === ModalDismissReasons.ESC) {

return 'by pressing ESC';

} else if (reason === ModalDismissReasons.BACKDROP_CLICK) {

return 'by clicking on a backdrop';

} else {

return `with: ${reason}`;
