# 🔳 QR Code Generator
A simple Node.js command-line application that generates a QR code from a user-provided URL and saves both the image and the original input locally.
## ✨ Technologies
- `Node.js`
- `JavaScript`
- `NPM`
- `Inquirer`
- `qr-image`
- `File System (fs)`
## 🚀 Features
- Command-line user input
- Generates a QR code image from a URL
- Saves the QR code as a PNG file
- Stores the original URL in a text file
- Uses Node.js built-in file system module
## 📍 The Process
This project was built by applying concepts learned in **Section 22 and Section 23 of The Complete Full-Stack Web Development Bootcamp**.
Section 22 introduced backend fundamentals such as servers, web applications, and how data is handled outside the browser. In Section 23, Node.js was introduced as a JavaScript runtime that allows JavaScript to run independently of the browser.
Using this knowledge, the project uses the `inquirer` package to collect user input from the terminal, the `qr-image` package to generate a QR code, and Node’s native `fs` module to save both the generated image and the original URL locally. The project also reinforced working with NPM, ECMAScript modules, and the `type: module` configuration.
