## What it is
qr-image is a dependency-free Node.js library for generating QR codes as PNG, SVG, EPS, or PDF images. It offers both streaming and synchronous APIs plus raw matrix output for custom rendering.

## Use cases
- generate qr code images in node.js
- serve qr codes from an express endpoint
- create svg qr codes for embedding in web pages
- generate qr code png buffers
- get raw qr code matrix data for custom rendering
- encode utf-8 text into a qr code

## When to choose
- you need a zero-dependency qr code generator for Node.js
- you need output formats beyond PNG such as SVG, EPS, or PDF
- you want stream-based or synchronous image generation
- you need raw QR matrix data to render yourself

## When to avoid
- you need QR generation in the browser without a bundler
- you need Kanji or mixed encoding modes
- you need an actively developed library with extensive tests
