Example

As we’re going to use a progress bar, We’ve to update app.module.ts used in the ngx-bootstrap Popover chapter to use ProgressbarModule and ProgressbarConfig.

Update app.module.ts to use the ProgressbarModule and ProgressbarConfig.

app.module.ts

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { AppComponent } from './app.component';
import { TestComponent } from './test/test.component';
import { AccordionModule } from 'ngx-bootstrap/accordion';
import { AlertModule,AlertConfig } from 'ngx-bootstrap/alert';
import { ButtonsModule } from 'ngx-bootstrap/buttons';
import { FormsModule } from '@angular/forms';
import { CarouselModule } from 'ngx-bootstrap/carousel';
import { CollapseModule } from 'ngx-bootstrap/collapse';
import { BsDatepickerModule, BsDatepickerConfig } from 'ngx-bootstrap/datepicker';
import { BsDropdownModule,BsDropdownConfig } from 'ngx-bootstrap/dropdown';
import { PaginationModule,PaginationConfig } from 'ngx-bootstrap/pagination';
import { PopoverModule, PopoverConfig } from 'ngx-bootstrap/popover';
import { ProgressbarModule,ProgressbarConfig } from 'ngx-bootstrap/progressbar';

@NgModule({
   declarations: [
      AppComponent,
      TestComponent
   ],
   imports: [
      BrowserAnimationsModule,
      BrowserModule,
      AccordionModule,
      AlertModule,
      ButtonsModule,
      FormsModule,
      CarouselModule,
      CollapseModule,
      BsDatepickerModule.forRoot(),
      BsDropdownModule,
      ModalModule,
      PaginationModule,
      PopoverModule,
      ProgressbarModule
   ],
   providers: [AlertConfig, 
      BsDatepickerConfig, 
      BsDropdownConfig,
      BsModalService,
      PaginationConfig,
      ProgressbarConfig],
   bootstrap: [AppComponent]
})
export class AppModule { }

Update test.component.html to use the modal.

test.component.html

<div class="row">
   <div class="col-sm-4">
      <div class="mb-2">
         <progressbar [value]="value"></progressbar>
      </div>
   </div>
   <div class="col-sm-4">
      <div class="mb-2">
         <progressbar [value]="value" type="warning"
            [striped]="true">{{value}}%</progressbar>
      </div>
   </div>
   <div class="col-sm-4">
      <div class="mb-2">
         <progressbar [value]="value" type="danger" 
            [striped]="true" [animate]="true"
            ><i>{{value}} / {{max}}</i></progressbar>
      </div>
   </div>
</div>

Update test.component.ts for corresponding variables and methods.

test.component.ts

import { Component, OnInit } from '@angular/core';

@Component({
   selector: 'app-test',
   templateUrl: './test.component.html',
   styleUrls: ['./test.component.css']
})
export class TestComponent implements OnInit {

   max: number = 100;
   value: number = 25;
   constructor() {}

   ngOnInit(): void {
   } 
}

Build and Serve
