In this example we will simply create one input field with timepicker, 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 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 timepicker.

so let's put bellow code:

src/app/app.component.html

<h1>Angular 8 Bootstrap Timepicker  Example - ItSolutionStuff.com</h1>
  
<ngb-timepicker [(ngModel)]="time"></ngb-timepicker>
  
<ngb-timepicker [(ngModel)]="time2" [meridian]="meridian"></ngb-timepicker>
<button class="btn btn-sm btn-outline-{{meridian ? 'success' : 'danger'}}" (click)="toggleMeridian()">
    Meridian - {{meridian ? "ON" : "OFF"}}
</button>
  
<hr/>
<pre>Selected time: {{time | json}}</pre>
<pre>Selected time: {{time2 | json}}</pre>

Step 4: Use Component ts File

Now we need to update our component.ts file here we will write code of bootstrap timepicker 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';
  
  time = {hour: 14, minute: 30};
  
  time2 = {hour: 15, minute: 30};
  meridian = true;
  
  toggleMeridian() {
      this.meridian = !this.meridian;
  }
  
  constructor() {}
   
}

Now we are ready to run both:

Run Angular App:

ng serve
