QR Code Generator in HTML CSS & JavaScript using QR Code API

By Alok Kumar

QR Code Generator in HTML CSS & JavaScript. Codes are capable of storing lots of data, and users can easily access the information by scanning the QR code.

This project is a web application that allows users to create QR codes by entering text or URLs. The app is built using HTML, CSS, and JavaScript. It consists of a form that contains an input field and a button for generating the QR code, as well as a container to display the generated QR code.

The form is styled using CSS to make it user-friendly and visually appealing. It has a responsive design that adapts to different screen sizes, making it accessible from desktop and mobile devices.

The QR code is generated using a third-party API called QRServer. The API generates a QR code image in response to a GET request with the data to encode. The app uses JavaScript to retrieve the data from the input field, send a GET request to the API, and display the generated QR code image.

The app has some additional features, such as checking if the input field is empty or if the same data was previously encoded. It also provides feedback to the user during the code generation process, changing the text of the button to indicate progress.

Overall, this project is a simple but useful tool that demonstrates how to integrate a third-party API with a web application to create QR codes. It also showcases some best practices for web development, such as responsive design and user feedback.
