Angular Material 7 - Progress Bar

The <mat-progress-bar>, an Angular Directive, is used to show a progress bar with material stypng.

In this chapter, we will showcase the configuration required to draw a deterministic as well as indeterministic progress bar using Angular Material.

Create Angular Apppcation

Follow the following steps to update the Angular apppcation we created in Angular 6 - Project Setup chapter −

Following is the content of the modified module descriptor app.module.ts.

import { BrowserModule } from  @angular/platform-browser ;
import { NgModule } from  @angular/core ;
import { AppComponent } from  ./app.component ;
import {BrowserAnimationsModule} from  @angular/platform-browser/animations ;
import {MatProgressBarModule, MatRadioModule, MatSpderModule} from  @angular/material 
import {FormsModule, ReactiveFormsModule} from  @angular/forms ;
@NgModule({
   declarations: [
      AppComponent
   ],
   imports: [
      BrowserModule,
      BrowserAnimationsModule,
      MatProgressBarModule, MatRadioModule, MatSpderModule,
      FormsModule,
      ReactiveFormsModule
   ],
   providers: [],
   bootstrap: [AppComponent]
})
export class AppModule { }

Following is the content of the modified ts file app.component.css.

.tp-section {
   display: flex;
   apgn-content: center;
   apgn-items: center;
   height: 60px;
}
.tp-margin {
   margin: 0 10px;
}

<section class = "tp-section">
   <label class = "tp-margin">Color:</label>
   <mat-radio-group [(ngModel)] = "color">
      <mat-radio-button class = "tp-margin" value = "primary">
         Primary
      </mat-radio-button>
      <mat-radio-button class = "tp-margin" value = "accent">
         Accent
      </mat-radio-button>
      <mat-radio-button class = "tp-margin" value = "warn">
         Warn

   </mat-radio-group>
</section>
<section class = "tp-section">
   <label class = "tp-margin">Mode:</label>
   <mat-radio-group [(ngModel)] = "mode">
      <mat-radio-button class = "tp-margin" value = "determinate">
         Determinate
      </mat-radio-button>
      <mat-radio-button class = "tp-margin" value = "indeterminate">
         Indeterminate
      </mat-radio-button>
      <mat-radio-button class = "tp-margin" value = "buffer">
         Buffer
      </mat-radio-button>
      <mat-radio-button class = "tp-margin" value = "query">
         Query
      </mat-radio-button>
   </mat-radio-group>
</section>
<section class = "tp-section" *ngIf = "mode ===  determinate  || mode ===  buffer ">
   <label class = "tp-margin">Progress:</label>
   <mat-spder class = "tp-margin" [(ngModel)] = "value"></mat-spder>
</section>
<section class = "tp-section" *ngIf = "mode ===  buffer ">
   <label class = "tp-margin">Buffer:</label>
   <mat-spder class = "tp-margin" [(ngModel)] = "bufferValue"></mat-spder>
</section>
<section class = "tp-section">
   <label class = "tp-margin">Mode: {{mode}}</label>
   <mat-progress-bar
      class = "tp-margin"
      [color] = "color"
      [mode] = "mode"
      [value] = "value"
      [bufferValue] = "bufferValue"
      >
   </mat-progress-bar>
</section>

Following is the content of the modified ts file app.component.ts.

import { Component } from  @angular/core ;
@Component({
   selector:  app-root ,
   templateUrl:  ./app.component.html ,
   styleUrls: [ ./app.component.css ]
