## What it is
QRCode.js is a dependency-free JavaScript library for generating QR codes in the browser using HTML5 Canvas or DOM tables. It works across a wide range of browsers, including legacy ones like IE6-10.

## Use cases
- generate qr codes in the browser
- render a qr code for a url on a webpage
- create qr codes without server-side dependencies
- support qr code generation in legacy browsers like ie
- dynamically update a qr code on user input

## When to choose
- you need a tiny, zero-dependency client-side qr code generator
- you must support very old browsers
- you want simple api with options for size, colors, and error correction level

## When to avoid
- you need qr code generation in node.js or react native
- you need advanced features like logos embedded in qr codes or svg output
- you need an actively developed library with recent bug fixes

## Facets
- artifact type: library
- maturity: maintenance
- function: ui-components, image-processing
- domain: web-development, frontend
- platform: browser, cross-platform
- tags: qrcode, canvas, zero-dependency, javascript
