This library takes in raw images and will locate, extract and parse any QR code found within. There's no polyfills for BigInt in the way it's coded in here. A pure javascript QR code reading library. There's no way to polyfill that and ponyfill libraries are way to big, but even if PDF 417 decoding relies on BigInt the rest of the library shall work ok in browsers that doesn't support it. In the PDF 417 decoder recent addition, the library now makes use of the new BigInt type, which is not supported by all browsers as well. You can use core-js to add support to these browsers. You can use external polyfills like WebRTC adapter to increase browser compatibility.Īlso, note that the library is using the TypedArray ( Int32Array, Uint8ClampedArray, etc.) which are not available in older browsers (e.g. The browser layer is using the MediaDevices web API which is not supported by older browsers.

Runs on your favorite ECMAScript ecosystem To read QR codes, we’ll be using the JavaScript port of the Java-based image processing library. There is otherwise no active development or roadmap for this project. The secret to reading QR codes is math, and the substitute for math is open-source libraries. No longer be published, so it's unlikely any changes will be accepted for it. Only bug fixes and minor enhancements will be considered.
