Hello, fellow developers! I'm excited to present my latest project: aQR Code Generator. This project is a great way to dive into JavaScript, focusing on how to dynamically generate QR codes based on user input. Whether you're new to web development or looking to enhance your JavaScript skills, this QR Code Generator project is an excellent opportunity to learn and create something useful.
TheQR Code Generatoris a web-based application that allows users to generate QR codes from any text input. This project demonstrates how to create a simple and interactive user interface, integrate third-party APIs, and handle user inputs effectively.
Here's a quick look at the project structure:
QR-Code-Generator/ ├── index.html ├── style.css └── script.js
To get started with the project, follow these steps:
Clone the repository:
git clone https://github.com/abhishekgurjar-in/QR-Code-Generator.git
Open the project directory:
cd QR-Code-Generator
Run the project:
The index.html file provides the basic structure of the QR Code Generator, including the input field and buttons for generating the QR code. Here’s a snippet:
The style.css file styles the QR Code Generator, providing a modern and user-friendly layout. Here are some key styles:
@import url("https://fonts.googleapis.com/css2?family=Poppins:wght@100;200;300;400;500;600;700&display=swap"); :root { --primary: #47185c; --primary-dark: #14001d; } * { margin: 0; padding: 0; box-sizing: border-box; } html { font-family: "Poppins", sans-serif; } body { background-color: var(--primary); } .container { display: grid; place-items: center; height: 80vh; } .box { padding: 20px; width: 400px; background-color: white; } .upper h1 { font-size: 32px; font-weight: 400; line-height: 32px; } form { display: flex; flex-direction: column; align-items: center; gap: 10px; margin-top: 10px; } form input { width: 100%; height: 40px; padding: 10px 15px; } form button { width: 100%; height: 40px; padding: 10px 15px; background-color: var(--primary); border: none; color: white; opacity: 0.9; transition: 0.3s ease-in; } .qr_container { border: 1px solid var(--primary); display: flex; justify-content: center; height: 0; opacity: 0; transition: opacity 0.3s ease-in, height 0.1s ease; } .qr_container.show { padding: 10px; height: 150px; opacity: 1; } .qr_container img { height: 100%; } .footer { color: white; margin: 50px; text-align: center; }
The script.js file manages the logic for generating the QR codes and handling user interactions. Here’s a snippet:
const qrFormEl = document.getElementById("qrForm"); const qrImageEl = document.getElementById("qrImage"); const qrContainerEl = document.getElementById("qrContainer"); const qrInputTextEl = document.getElementById("qrInputText"); const generateBtnEl = document.getElementById("generateBtn"); const renderQRCode = (url) => { if (!url) return; generateBtnEl.innerText = "Generating QR Code..."; qrImageEl.src = url; qrImageEl.addEventListener("load", () => { qrContainerEl.classList.add("show"); generateBtnEl.innerText = "Generate QR Code"; }); }; qrFormEl.addEventListener("submit", (event) => { event.preventDefault(); const formData = new FormData(qrFormEl); const text = formData.get("qrText"); const qrCodeUrl = `https://api.qrserver.com/v1/create-qr-code/?size=150x150&data=${text}`; renderQRCode(qrCodeUrl); }); qrInputTextEl.addEventListener("keyup", () => { if (!qrInputTextEl.value.trim()) { qrContainerEl.classList.remove("show"); } });

Building this QR Code Generator was a fun and educational experience that helped me better understand JavaScript and how to work with APIs to create dynamic web applications. I hope this project inspires you to build something cool with JavaScript too. Happy coding!
This project was developed as part of my journey to enhance my web development skills, focusing on JavaScript and user interaction.
