QR Code Library

QR Code Library is a lightweight JavaScript library for generating QR codes from a URL or text message.

Installation

You can install the QR Code Library via npm by using the following command:

npm qr-code-library

Usage

To use the QR Code Library, you need to import it into your project:

import QRCodeGenerator from 'qr-code-library';

Next, you can create a new QRCodeGenerator object and generate a QR code using the generate() method:

const qrcode = new QRCodeGenerator();
const qrData = 'Hello, QR code!';
const qrCodeImage = qrcode.generate(qrData);

The provided code creates a QR code by generating a new object from the QRCodeGenerator class and using the generate() method with specified data. The resulting QR code is returned as an image representation.

You have the flexibility to customize the QR code with options like size, color, and error correction level. Here's an example showcasing how to specify these options.

const qrcode = new QRCodeGenerator();

qrcode.setSize(200); // Specify the size of the QR code in pixels
qrcode.setDarkColor('#000000'); // Specify the color of the dark modules
qrcode.setLightColor('#FFFFFF'); // Specify the color of the light modules
qrcode.setErrorCorrection(QRCodeGenerator.ErrorCorrectionLevel.HIGH); // sets the error correction level of the QR code to high. Higher error correction levels provide better resilience to damage or printing imperfections, but result in a denser QR code

const qrCodeImage = qrcode.generate(qrData); // Generate the QR code image

Guided Examples

Exemple 1 : Generate a QR code for a URL link

const qrcode = new QRCodeGenerator();
const qrData = 'https://www.example.com';
const qrCodeImage = qrcode.generate(qrData);

Exemple 2 : Generate a QR code for a text message

const qrcode = new QRCodeGenerator();
const qrData = 'Hello, QR generator!';
const qrCodeImage = qrcode.generate(qrData);
