Introduction

In this article, we are going to learn how to create a progress bar using ngx-bootstrap in Angular 8.

Ngx-Bootstrap has released a package of open-source tools which is native Angular directives for Bootstrap 3 and 4. It contains all core components powered by Angular. In this article we will learn about Typehead component which is a cool feature of Ngx-bootstrap.

What Is Progress Bar?

A Progress bar is a component in GUI which is used to visualize the progression of a task which is completed, such as the percentage of amount that is completed during downloading.

In Ngx-bootstrap progressbar there are normal, striped and striped with animated striped progress bar.

Prerequisites

  • Basic knowledge of Angular
  • Visual Studio Code must be installed
  • Angular CLI must be installed
  • Node JS must be installed

Step 1

Let's create a new Angular project using the following NPM command,

TypeScript
 




x


 
1
ng new progressBar  


 

Step 2

Now, let's create a new component by using the following command,

TypeScript
 




xxxxxxxxxx
1


 
1
ng g c ngx-bootstrap-progressbar


 

Step 3

Install ngx-bootstrap from npm by using the folowing command.

TypeScript
 




xxxxxxxxxx
1


 
1
npm install ngx-bootstrap --save  



Or,

TypeScript
 




xxxxxxxxxx
1


 
1
ng add ngx-bootstrap --component progressbar



Step 4

Now let's add bootstrap styles in our index.html file .

For Bootstrap 3,

HTML
 




xxxxxxxxxx
1


 
1
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"> 


 

For Bootstrap 4,

HTML
 




xxxxxxxxxx
1


 
1
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" rel="stylesheet">  



Step 5

Let add the template in our ngx-bootstrap-progressbar.component.html.


  1. HTML
     




    xxxxxxxxxx
    1
    27


     
    1
    <div class="row">    
    2
      <h2 style="margin: auto;">Example of Ngx-Bootstrap Progress Bar</h2>    
    3
      <div class="col-sm-8" style="margin: 10px;">    
    4
        <div style="margin: 10px;">    
    5
          <button (click)="showProgressBar(1)" class="btn btn-primary">Show Normal Progress Bar</button>    
    6
        </div>    
    7
        <div *ngIf="normalPB" class="mb-2">    
    8
          <progressbar [value]="55"></progressbar>    
    9
        </div>    
    10
      </div>    
    11
      <div class="col-sm-8" style="margin: 10px;">    
    12
        <div style="margin: 10px;">    
    13
          <button (click)="showProgressBar(2)" class="btn btn-primary">Show Striped Progress Bar</button>    
    14
        </div>    
    15
        <div *ngIf="stripedPB" class="mb-2">    
    16
          <progressbar [value]="35" type="danger" [striped]="true">35%</progressbar>    
    17
        </div>    
    18
      </div>    
    19
      <div class="col-sm-8" style="margin: 10px;">    
    20
        <div style="margin: 10px;">    
    21
          <button (click)="showProgressBar(3)" class="btn btn-primary">Show Animated Progress Bar</button>    
    22
        </div>    
    23
        <div *ngIf="animatedPB" class="mb-2">    
    24
          <progressbar max="200" [value]="180" type="success" [striped]="true" [animate]="true"><i>180 / 200</i></progressbar>    
    25
        </div>    
    26
      </div>    
    27
    </div>    


Step 6

 Now, open the ngx-bootstrap-progressbar.component.ts file and add the following code in this file.

TypeScript
 




xxxxxxxxxx
1
24


 
1
import { Component } from '@angular/core';    
2
    
3
@Component({    
4
  selector: 'app-progress-bar',    
5
  templateUrl: './progress-bar.component.html'    
6
     
7
})    
8
export class AngularProgressBarComponent {    
9
  normalPB: boolean;    
10
  stripedPB: boolean;    
11
  animatedPB: boolean;    
12
    
13
  showProgressBar(value){    
14
    // Value =1 Normal Progress bar    
15
    // Value =2 Striped Progress bar    
16
    // Value =3 Animated Progress bar    
17
    this.normalPB=false;    
18
    this.stripedPB=false;    
19
    this.animatedPB=false;    
20
    
21
    value ==1 ? this.normalPB=true : value ==2 ?  this.stripedPB=true : this.animatedPB=true;    
22
      
23
  }    
24
}    



Step 7

Now, open the app.component.html file and add the following code in the file,

HTML
 




xxxxxxxxxx
1


 
1
<app-ngx-bootstrap-progressbar></app-ngx-bootstrap-progressbar>  



Step 8

Let's open app.module.ts file and add the following code in the file,

TypeScript
 




xxxxxxxxxx
1
21


 
1

          
2
import { BrowserModule } from '@angular/platform-browser';    
3
import { NgModule } from '@angular/core';    
4
import { FormsModule} from '@angular/forms';    
5
import { AppComponent } from './app.component';    
6
import {ProgressbarModule} from 'ngx-bootstrap/progressbar';    
7
import {ProgressBarComponent } from './progress-bar/progress-bar.component';    
8
    
9
@NgModule({    
10
   declarations: [    
11
      AppComponent,    
12
      ProgressBarComponent     
13
   ],    
14
   imports: [    
15
      BrowserModule,    
16
      FormsModule,    
17
      ProgressbarModule    
18
      ],    
19
   bootstrap: [AppComponent]    
20
})    
21
export class AppModule { }    



Now it's time for the output,

 

 

This is the normal progress bar which we can use with different bootstrap supported contextual classes : success, info, warning, danger

This is the striped progress bar which has striped lines to show the amount of tasks done. 


This is the animated progress which looks like it is in progress .

Though we can use these progress bars dynamically we just want to replace the value field with our dynamic variable. 

Conclusion

In this article, we have seen the Ngx-Bootstrap progress bar Component in an Angular 8 application.

I hope you have enjoyed this article, as I have enjoyed writing and coding the examples.

Please let me know how to improve it.
