Example

As we”re going to use a progressbar, We”ve to update app.module.ts used in 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 {
   } 
}
