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.

WebAssembly compiles really slow in Safari for iOS according to our tests.

</html>Fixed a memory leak related to mTimeout in RuntimeSettings.
Built Dynamsoft Barcode Reader 6.4.1 to JS(WebAssembly) version.
Combined the normal and the mobile version into one.
Added built-in Worker support.
// The default value is false. By setting this value to true to decode in another thread, therefore UI wouldn't get stuck.
dynamsoft.dbrEnv.bUseWorker = true;Set dbr-<version>.js(stable) as the main branch.
Added dbr-<version>.mobile.js(smaller, compiles quicker, requires less memory, but not as stable) for mobile Safari.
Built Dynamsoft Barcode Reader 6.3.0 to JS(WebAssembly) version.
