Hey, that's what I initially thought as well! Turns out 1D/2D barcode scanning is a surprisingly involved topic, with tons of research papers. It's a topic with both depth (like advanced recognition techniques for certain types of codes) and breadth (wide variety of code types). As mentioned, there are several OSS competitors, mainly QuaggaJS and ZXing which is at the core of some wrappers like JsQRScanner or HTML5QRCode.
