QuaggaJS is a barcode-scanner library written entirely in JavaScript that supports real-time localization and decoding of barcode types such as EAN, CODE 128, CODE 39, UPC-A, and CODABAR. It can analyze static images or access the user's camera via getUserMedia for live-stream decoding, with a locator that is invariant to scale and rotation.

Use cases

  • scan barcodes from the device camera in a web app
  • decode EAN or UPC barcodes from product images
  • read CODE 128 barcodes from static images in the browser
  • build a barcode scanner that works on smartphones without a native app
  • detect rotated or scaled barcodes in images
  • add barcode scanning to a web-based inventory tool

When to choose

  • you need pure-JavaScript barcode decoding in the browser without native dependencies
  • you need to scan barcodes from a live camera stream or static images
  • you need rotation- and scale-invariant barcode localization
  • you need support for many 1D barcode formats like EAN, UPC, CODE 128, and CODABAR

When to avoid

  • you need to scan 2D codes like QR codes or Data Matrix
  • you need a maintained library with active development and recent fixes
  • you need native mobile performance for high-volume industrial scanning
  • you need server-side decoding in a non-JavaScript environment
