Version 6.4.1.1
The repository aims to help developers get familiar with Dynamsoft JavaScript Barcode SDK.
This SDK supports decoding 1D, PDF417, QR, DataMatrix, and Aztec.
The supported data sources include Blob, HTMLImageElement, HTMLVideoElement, URL and more.
The LocalizationResult(like C# LocalizationResult) can be found in decoding results.
If you want the nodejs version, please visit dbr webassembly.

Build Dynamsoft Barcode Reader 6.4.1 to JS(webassembly) version.
Combine the normal and the mobile version into one.
Add built-in worker support.
// The default value is false. Set it true to decode in another thread. By this way, UI would not stuck.
dynamsoft.dbrEnv.bUseWorker = true;Set dbr-<version>.js(stable) as the main branch.
Add dbr-<version>.mobile.js(smaller, compile quicker, need less memory, but not that stable) for the mobile safari.
Build Dynamsoft Barcode Reader 6.3.0 to JS(webassembly) version.
