JavaScript Barcode Reader Coming Soon

Dynamsoft Barcode Reader JavaScript Edition is a JavaScript API for barcode scanning based on the WebAssembly technology. It supports real-time localization and decoding of various types of barcodes. The library is capable of scanning barcodes from a static image, and more importantly, directly from a live video stream. It supports reading multiple barcodes at a time.

Before going any further, I suggest you try the demo from a desktop browser or mobile browser to see it in action.

The core of Dynamsoft Barcode Reader is written in C++ for performance. We compiled the library to WebAssembly so that it can run alongside with JavaScript.

Estimated Performance

Generally speaking, the performance heavily depends on the network connection, device and browser used. Below is some preliminary data from our testing. The “1st load” column lists the time spent on downloading the WASM file and compilation when a user first accesses the above demo page. The “2nd load” column lists the time spent on page load from the second time forward. The last column lists the time spent on localizing and decoding multiple barcodes off one video frame.

Device Browser 1st load(ms) 2nd load(ms) Average time spent on barcode reading
Win10 CPU:i7-6700 Chrome 67 4,322 3,732  172

Overall, WebAssembly edition comes with a clear advantage: your end users don’t need to install anything to use your application; Meanwhile, this relatively new technology relies on browsers a lot so the performance might be an issue, especially for the first time load. The loading performance will be improved down the road. Please contact us if you have questions choosing the right edition and would like to optimize the reading accuracy or the performance.
