This library is a client-side utility for generating QR code matrix patterns directly within web browsers. It functions as a frontend tool that converts text strings, URLs, and contact information into scannable visual data without requiring server-side processing.

The library provides a platform-agnostic interface that renders these patterns using either HTML5 canvas elements or dynamic document object model node injection. It incorporates matrix-based data encoding and Reed-Solomon error correction to ensure that the generated patterns remain readable even if portions of the image are damaged.

The project supports the creation of various scannable assets, including contact information for mobile address books and dynamic data visualizations. It is designed for integration into web interfaces to facilitate the embedding of machine-readable information.
