What is QuaggaJS?

QuaggaJS is a barcode-scanner entirely written in JavaScript supporting real- time localization and decoding of various types of barcodes such as EAN, CODE 128, CODE 39, EAN 8, UPC-A, UPC-C, I2of5 and CODABAR. The library is also capable of using getUserMedia to get direct access to the user's camera stream. Although the code relies on heavy image- processing even recent smartphones are capable of locating and decoding barcodes in real-time.
