# QR Code Styling

JavaScript library for generating QR codes with a logo and styling.

**This is a NodeJS fork of the QR code styling repo [qr-code-styling](https://github.com/kozakdenys/qr-code-styling),
supporting NodeJs as well as svg exports. If you are looking for browser support head to the original project**

Try it here https://qr-code-styling.com

together.
