Building a Custom QR Code Generator with qrcode.js and JavaScript
Hello friends, today in this blog, we will learn how to build a custom QR code generator with qrcode.js and JavaScript. In our previous blog, we saw how to create a music player using HTML, CSS, and JavaScript. You can check my other javascript projects after reading this blog.
QR codes have become increasingly popular over the years due to their ability to store a large amount of information in a small space. They are widely used for various purposes, such as tracking inventory, sharing contact information, and making payments. However, creating custom QR codes tailored to specific needs and branding can be challenging.
This tutorial will show you how to build a custom QR code generator using qrcode.js and JavaScript. qrcode.js is a JavaScript library that allows you to generate QR codes quickly, while JavaScript is a versatile programming language that can be used to build web applications.
By the end of this tutorial, you will have a custom QR code generator that allows you to generate QR codes with customizations such as logos, colors, and background images. This will enable you to create QR codes that are not only functional but also visually appealing and in line with your brand’s image.
what is qrcode.js?
qrcode.js is a JavaScript library that makes it easy to generate QR codes. Before we can use qrcode.js to create our custom QR code generator, we need to install and set it up. There are a few ways to use it such as downloading local file, CDN link, and NPM. You can check its GitHub documentation here.
In this project, as you can see in the above image we have five buttons for generating different types of QR codes. We can create QR for any text or paragraph, URL, E-mail, Phone, or SMS. After filling in all the fields the QR will be generated. After generating QR we can download it.
Code of HTML, CSS, and JavaScript Files
Here’s the good news: you don’t have to write all the code of this project from scratch! I have created a GitHub repository that contains all the HTML, CSS, and JavaScript code needed to build the app. You can check it out and use it as a starting point for your own project.
