Step 1 – Install  plugins

Step 2 – Import the NgxBarcodeModule into the module you want to use :

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import { HeaderComponent } from './components/header/header.component';
import { NgxBarcodeModule } from 'ngx-barcode';
import { FormsModule, ReactiveFormsModule } from '@angular/forms';

@NgModule({
  declarations: [
    AppComponent,
    HeaderComponent
  ],
  imports: [
    BrowserModule,
    AppRoutingModule,
    NgxBarcodeModule,
    ReactiveFormsModule,
    FormsModule
  ],
  providers: [],
  bootstrap: [AppComponent]

export class AppModule { }

Step 3 –After you’ve imported the library, you can use the ngx-barcode component in your Angular app:

<div> 
<h3> {{title}} </h3>
<textarea  placeholder="bc-value" [(ngModel)]="value"></textarea>
<ngx-barcode *ngFor="let bcValue of values" [bc-value]="value" [bc-display-value]="true"></ngx-barcode>
</div>

Step 4 –Make the following code modifications to the app components ts.

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

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.scss']
})
export class AppComponent {
  title = 'Barcode generator';
  value = '';
  
  get values(): string[] {
    return this.value.split('\n');
  }
 
}
