Hi,

I will explain step by step tutorial angular 12 bootstrap datepicker. This tutorial will give you simple example of how to use bootstrap datepicker in angular 12. let’s discuss about angular 12 ng-bootstrap-datepicker. This article will give you simple example of bootstrap datepicker in angular 12.

Ng Bootstrap is developed from bootstrap and they provide all bootstrap 3, bootstrap 4 and bootstrap 5 native Angular 12 directives like model, pagination, datepicker, buttons etc. Ng Bootstrap will help to easily use bootstrap ui.

In this example we will simply create one input field with datepicker, so you can use in your angular 12 application. we will use model step by step, so you can easily understand.

Step 1: Create New App

You can easily create your angular app using bellow command:

ng new my-new-app

Step 2: Install Bootstrap 5

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 and FormsModule 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';
import { FormsModule } from '@angular/forms';
  
@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule, 
    NgbModule,
    FormsModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

Step 5: Updated View File

Now here, we will updated our html file. we will create simple bootstrap input fields for datepicker.

so let's put bellow code:

src/app/app.component.html

<h1>Angular 12 Bootstrap 5 Datepicker Example - ItSolutionStuff.com</h1>
  
<form class="form-inline">
  <div class="form-group">
    <div class="input-group">
      <input class="form-control" placeholder="yyyy-mm-dd"
             name="dp" [(ngModel)]="model" ngbDatepicker #d="ngbDatepicker">
      <div class="input-group-append">
        <button class="btn btn-outline-secondary calendar" (click)="d.toggle()" type="button"></button>
      </div>
    </div>
  </div>
</form>
   
<hr/>
<pre>Model: {{ model | json }}</pre>

Step 4: Use Component ts File

Now we need to update our component.ts file here we will write code of bootstrap datepicker model, let's update as like bellow:

src/app/app.component.ts

import { Component } from '@angular/core';
  
@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  title = 'appBootstrap';
  
  model:any;
  
  constructor() {}
    
}

Now we are ready to run both:

Run Angular App:

ng serve
