How to use Bootstrap Modal in Angular?

Here, i would like to give you example of angular bootstrap 4 modal popup. i will give you simple example of how to create bootstrap modal in angular application. you can see bellow example of how to implement bootstrap modal in angular.

You can easily use bootstrap 4 modal in angular 6, angular 7, angular 8, angular 9, angular 10, angular 11, angular 12, angular 13, angular 14, angular 15, angular 16 and angular 17 application.

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

In this example we will simply create one model popup, so you can use in your angular 8 application. we will use model step by step, so you can easily understand.

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.

angular.json

.....
    "styles": [
      "node_modules/bootstrap/dist/css/bootstrap.min.css",
      "src/styles.css"
    ],
.....

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:

src/app/app.module.ts

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
  
import { AppComponent } from './app.component';
  
import {NgbModule} from '@ng-bootstrap/ng-bootstrap';
   
@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule, 
    NgbModule
  ],
  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:

src/app/app.component.html

<h1>Angular 8 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>
    </button>
  </div>
  <div class="modal-body">
    This is example from ItSolutionStuff.com
  </div>
  <div class="modal-footer">
    <button type="button" class="btn btn-outline-dark" (click)="modal.close('Save click')">Ok</button>
  </div>
</ng-template>

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:

src/app/app.component.ts

import { Component } from '@angular/core';
  
import {NgbModal, ModalDismissReasons} from '@ng-bootstrap/ng-bootstrap';
  
@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  title = 'appBootstrap';
  
  closeResult: string;
  
  constructor(private modalService: NgbModal) {}
    
  open(content) {
    this.modalService.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}`;
    }
  }
}

Now we are ready to run both:
