Deepgram QR Code Generator

CLI tool for generating branded Deepgram QR codes from the command line. Uses the same qr-code-styling library as the original browser tool — output is identical.

Each generated QR code includes:

• Large circular dots (the qr-code-styling "dots" style)
• Extra-rounded corner squares
• Deepgram logo centred in the QR matrix
• White padding border
• "POWERED BY DEEPGRAM" branding strip at the bottom

Prerequisites

• Node.js 18+ and pnpm

• System libraries required by the canvas package (Cairo, Pango, etc.):

  # Ubuntu / Debian
  sudo apt-get install build-essential libcairo2-dev libpango1.0-dev libjpeg-dev libgif-dev librsvg2-dev
  
  # macOS (Homebrew)
  brew install pkg-config cairo pango libpng jpeg giflib librsvg pixman
  

  See the canvas installation docs for other platforms.

Setup

pnpm install

Usage

pnpm generate -- <url> [<url> ...]

Examples

Generate a single QR code:

pnpm generate -- https://dpgr.am/ucb-ai-careers

Generate multiple QR codes in one go:

pnpm generate -- https://dpgr.am/ucb-ai-careers https://dpgr.am/ucb-ai-intern

URLs without a scheme are accepted — https:// is prepended automatically:

pnpm generate -- dpgr.am/ucb-ai-careers

Output

Generated files are saved to the output/ directory (created automatically). Each file is named after the URL slug:

output/dpgr-am-ucb-ai-careers.png
output/dpgr-am-ucb-ai-intern.png

The output/ directory is gitignored — generated files are not committed to the repo.
