## What it is
JsBarcode is a dependency-free JavaScript barcode generation library supporting formats like CODE128, EAN/UPC, CODE39, ITF, MSI, Pharmacode, and Codabar. It renders barcodes to SVG, canvas, or image elements in the browser and works in Node.js.

## Use cases
- generate barcodes in the browser
- render EAN-13 product barcodes on a webpage
- create barcode images in Node.js
- generate CODE128 barcodes as SVG
- print shipping or inventory labels with barcodes
- add barcodes to invoices or tickets

## When to choose
- you need barcode rendering in JavaScript with no dependencies
- you need many barcode formats (EAN, UPC, CODE128, CODE39, ITF, MSI, Pharmacode, Codabar)
- you want output to SVG, canvas, or img elements
- you need both browser and Node.js support

## When to avoid
- you need QR codes or 2D barcode formats
- you need server-side barcode image generation in another language
- you need barcode scanning/reading rather than generation

## Facets
- artifact type: library
- maturity: stable
- function: image-processing, ui-components
- domain: web-development, frontend, developer-tools
- platform: browser
- tags: barcode-generator, code128, ean, upc, svg, canvas, no-dependencies, nodejs, javascript
