Download and type "npm init" in your terminal. Then run the file app.js; Insert Link to create QRCode. This project create as QR Code in PNG Format and it will also create a text file which will contain the link you inputted. In this project npm package: inquirer, qr-images. Node native module file system has also been used.
Let me explain how the QR Code Generator works without diving into the actual code:
-
User Input: The QR Code Generator is a Node.js application that interacts with the user through the command-line interface. It prompts the user to enter a URL.
-
QR Code Generation: After the user enters the URL, the application uses the
qr-image
npm package to generate a QR code image for the provided URL. A QR code is a two-dimensional barcode that can store various types of information, such as URLs, text, contact details, and more. -
Saving the QR Code Image: Once the QR code image is generated, the application saves it as a PNG file named
qrcode.png
in the same directory as the application. -
Creating a Text File: The application also creates a text file named
user_input.txt
to record the user's input and the associated QR code image URL. The text file contains two lines: one indicating the user-entered URL and the other indicating the filename of the QR code image. -
User Output: Upon successful execution, the application provides feedback to the user, notifying them that the text file
user_input.txt
has been created, and the QR code image has been saved asqrcode.png
.
By running this application, users can generate QR code images for any URLs they provide and keep track of the URLs and corresponding QR codes through the user_input.txt
file. It can be useful for creating QR codes for websites, sharing links, or storing data that can be easily scanned by QR code readers and apps.
