How to generate QR code in Angular 16

QR codes are becoming more and more popular as a way to share information quickly and easily. In this article, we will show you how to generate QR codes in Angular 16 using a simple and efficient method.

Step 1: Install the necessary package

First, you will need to install the ngx-qrcode2 package, which will allow you to easily generate QR codes in your Angular 16 application. You can do this by running the following command in your terminal:

npm install ngx-qrcode2

Step 2: Import the module

Once the package is installed, you will need to import the QRCodeModule into your Angular module. Open the app.module.ts file and add the following line:

import { QRCodeModule } from 'angularx-qrcode';

Then, add QRCodeModule to the imports array of your NgModule decorator:

@NgModule({
imports: [
//...
QRCodeModule
],
//...
})

Step 3: Use the QR code component

Now you can use the QR code component in your Angular 16 application. Simply add the following line to your HTML template where you want the QR code to appear:

<qrcode [qrc-value]="'YourQRCodeValueHere'" [qrc-element-type]="'img'"></qrcode>

Replace ‘YourQRCodeValueHere’ with the content you want to encode in the QR code. You can also specify the element type (img, canvas, or svg) using the qrc-element-type attribute.

Step 4: Customize the appearance (optional)

If you want to customize the appearance of the QR code, you can do so using CSS. Simply target the qrcode element and apply your desired styles:

qrcode {
width: 200px;
height: 200px;
}

Conclusion

Generating QR codes in Angular 16 is a simple and efficient process with the ngx-qrcode2 package. By following the steps outlined in this article, you can easily integrate QR code generation into your Angular application and start sharing information in a convenient and modern way.
