What it is

QRCode.js is a lightweight JavaScript library that generates QR codes using HTML5 Canvas or DOM table elements, with no external dependencies. It encodes arbitrary text (typically URLs) into scannable QR code images that render cross-browser from IE6 through modern browsers and mobile platforms. Monolithic structure: qrcode.js contains the full generator implementation; qrcode.min.js is the production build. HTML demo files (index.html, index-svg.html) show usage patterns. No src/ or dist/ folder separation; all source is flat at root level.

Start here

Open these first:

• qrcode.js — Main library implementation containing QRCode class, encoding logic, and rendering engines for Canvas and table-based output.
• README.md — Documents API, usage patterns, browser compatibility, and library capabilities that all contributors must understand.
• index.html — Primary demo page showing standard Canvas-based QR code generation and common usage patterns.
• index-svg.html — Alternative demo page demonstrating SVG-based rendering for vector output support.
• qrcode.min.js — Production-ready minified bundle used in deployment and performance-critical environments.

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

Clone and open in a browser:

git clone https://github.com/davidshimjs/qrcodejs.git
cd qrcodejs
open index.html

No build or install step is required; it is a pure JavaScript library with no npm or package manager setup.

Daily commands:

No dev server required. Open index.html or index-svg.html directly in a browser to see demo. Include qrcode.js (or qrcode.min.js for production) via <script> tag in your HTML.

Key cautions & unknowns

• Stale — last commit 2y ago
• No CI workflows detected
• No tests detected in the complete Git tree
• No build or transpilation step: qrcode.js uses ES5 syntax only; do not assume ES6 module support or modern JavaScript features. No visible error handling or input validation in the README examples—passing invalid text…
• Published-advisory coverage was unavailable for the captured dependencies.
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.
