## What it is
A pure JavaScript barcode generation library supporting over 100 barcode types and standards, translated from Barcode Writer in Pure PostScript. It renders barcodes as PNG images, canvas drawings, or SVG across browsers, Node.js, React, React Native, and Electron.

## Use cases
- generate qr codes in javascript
- create barcode images in node.js
- render code128 barcodes in the browser
- generate ean/upc barcodes for retail labels
- produce svg barcodes for web pages
- generate gs1 datamatrix codes
- add barcode generation to a react native app

## When to choose
- you need broad barcode symbology coverage (100+ types) in pure JavaScript
- you need cross-platform rendering to PNG, canvas, or SVG
- you need GS1-compliant symbols like DataBar, QR, or DataMatrix

## When to avoid
- you need to scan or decode barcodes rather than generate them
- you need barcode generation outside the JavaScript ecosystem

## Facets
- artifact type: library
- maturity: stable
- function: image-processing, cli, sdk
- domain: web-development, developer-tools, cross-platform
- platform: browser, cross-platform, cli
- tags: barcode-generator, qr-code, code128, datamatrix, svg, png, react-native, gs1, nodejs, electron
