In this guide, we will build a simple Node.js script that creates a short link and then generates a QR code for it.

​
Prerequisites

  • Node.js installed
  • A Linkryse API Key
  • qrcode npm package
npm install @linkryse/sdk qrcode

​
The Script

const { Linkryse } = require('@linkryse/sdk');
const QRCode = require('qrcode');
const fs = require('fs');

const linkryse = new Linkryse({ apiKey: 'sk_live_...' });

async function generate() {
  // 1. Create a Short Link
  const link = await linkryse.links.create({
    url: 'https://example.com/promotion',
    key: 'promo-qrcode'
  });

  console.log(`Link created: ${link.shortLink}`);

  // 2. Generate QR Code
  // Linkryse short links automatically support QR code generation by appending ?qr=1
  // But here is how to do it manually for custom processing:
  
  await QRCode.toFile('qr.png', link.shortLink);
  console.log('QR code saved to qr.png');
}

generate();
