Yet Another Barcode Library?

This is not just another port of the great zxing library but rather an extension of it. This implementation includes a barcode locator capable of identifying barcode-like patterns in an image, resulting in an estimated bounding box that accounts for rotation. Simply put, this reader is invariant to scale and rotation, whereas other libraries require the barcode to be aligned with the viewport.

Browser Support

Quagga utilizes many modern Web APIs, which are not yet supported by all browsers. Quagga operates in two modes:

1. Analysing static images.
2. Using a camera to decode images from a live stream.

The latter mode requires the presence of the MediaDevices API. You can track the compatibility of the Web APIs used in each mode:

• Static Images.
• Live Stream.

Supported Barcodes

Quagga supports the following barcode formats:

• Code-128
• EAN-13
• EAN-8
• Code-39
• Code-39-VIN
• Codabar
• UPC-A
• UPC-E
• Interleaved 2 of 5 (ITF)
• Standard 2 of 5
• Code-93
