pdf417 barcode reader/decoder in javascript?

I would like to read/decode pdf417 barcode from my web app targeted to run only on mobile browsers. I have seen many barcode reader javascript libs online but none of them supporting reading of pdf417 barcode(one of the most popular barcode type) off-course creation of pdf417 was supported by them.

What I am looking for is a javascript based library to read/decode pdf417 barcode, I know how to achieve this with phonegap or native. I am expecting purely js based solution

Is PDF417 a QR code?

A QR code (Quick Response code) is a 2D barcode type. It consists of black squares arranged in a square grid on a white background, which can be read by a camera, scanner, or other imaging devices. PDF417 barcodes are a type of stacked, variable length, bi-directional 2D barcode.

We created a library to do just that, https://github.com/PeculiarVentures/js-zxing-pdf417, unlike the Android-only solution above this is pure Javascript and will work in all browsers.
