How to implement Ionic Barcode Scanner using cordova

In these articles, we will learn how to use an Ionic Barcode Scanner. We will use a plugin called Cordova-plugin-barcode scanner to a barcode and this opens a camera view and automatically scans a barcode, returning the data back to you.

Setting up and configure Ionic Barcode scanner

Let first create a project to implement an Ionic barcode scanner.

ionic start barcodeScanner blank --type=angular
cd barScanner

Ionic barcode scanner

Let add and install barcode-scanner

ionic cordova plugin add phonegap-plugin-barcodescanner
npm install @ionic-native/barcode-scanner
Ionic barcode Scanner
Ionic barcode scanner

Add the following code in the template

       Ionic Scanner

  <div class="ion-padding">
    <ion-button full icon-left (click)="createCode()>
     <ion-icon name="barcode"></ion-icon>Create

     <ion-card *ngIf="scannedCode">
         Result from scan: {{ scannedCode }}

Step 4: Add the following code in the file

import { Component } from '@angular/core';
import { BarcodeScanner } from '@ionic-native/barcode-scanner/ngx';

  selector: 'app-home',
  templateUrl: '',
  styleUrls: [''],
export class HomePage {
  scannedCode = null;

  constructor(private barcodeScanner: BarcodeScanner) {}

  scanCode () {
    this.barcodeScanner.scan().then(barcodeData => {
      this.scannedCode = barcodeData.text;


Step 5: Add the following BarcodeScanner provider in app.module.ts

import { NgModule } from '@angular/core';
import { BarcodeScanner } from '@ionic-native/barcode-scanner/ngx';
import { AppComponent } from './app.component';
import { AppRoutingModule } from './app-routing.module';

  declarations: [AppComponent],
  entryComponents: [],
  imports: [
  providers: [
    { provide: RouteReuseStrategy, useClass: IonicRouteStrategy },
  bootstrap: [AppComponent]
export class AppModule {}
