QR Code Renderer

is a dependency-free library to render QR Codes. The library makes it simple to integrate with any UI framework and comes with a prebuilt SVG renderer for the web.

The library consists of a core package (@qrcode-renderer/core) responsible for the encoding of the QR Code. It also provides utilities to integrate the renderer with any UI library. This monorepo will also host "bridge" packages (@qrcode-renderer/<ui-framework>) for any UI libraries that we choose to natively support.
