barKoder Web SDK v1.3.8 Released — Major Enhancements & Fixes

New Major barKoder Web SDK v1.3.8 Released

We’re excited to announce the release of barKoder Web SDK v1.3.8, packed with important bug fixes, enhanced camera handling, expanded decoder support, and new features that make our JavaScript barcode scanning SDK even more powerful for developers across desktop and mobile.

Whether you’re building enterprise-grade applications in React, Angular, or integrating barKoder into your own custom web app, this update delivers better flexibility, performance, and error handling for a smoother developer experience.

What's New in v1.3.8

Enhanced Camera Selection and UI Fixes

• Fixed a bug causing incorrect camera selection in the cameraPicker UI on desktop browsers.

• iPhones with high minimum focus distance (e.g. iPhone 14 Pro, 15 Pro) now correctly default to the best available camera (e.g. Back Triple Camera).

• Improved error logging and camera capability detection logic.

Improved Location Drawing in Continuous Mode

• Visuals for barcode location overlays have been improved with:

  • Smoother rendering

  • Updated line colors for better contrast and usability

applyTemplate Method: Smarter, Safer, More Capable

The applyTemplate() method received a major overhaul:

• Now returns a Promise for asynchronous handling

• Introduced structured error objects (JSONFileError, JSONValueError) with detailed messages

• No more silent fallbacks — missing templateMode now throws an error

• Skips non-existent non-end-nodes gracefully

Newly supported decoders in templates:

• Upc-E1

• Datalogic 25

• Added dpmMode support for QR codes

New SDK Settings & Configurations

You now have access to even more granular configuration options via template or programmatic setup:

• locationLineColor, locationLineWidth

• roiLineColor, roiLineWidth, roiOverlayBackgroundColor

• imageResultEnabled, locationInImageResultEnabled, locationInPreviewEnabled

• regionOfInterestVisible, barkoderResolution, beepOnSuccessEnabled

These settings now also accept both boolean and number types, giving you more flexibility.

Affected settings include:
enableMisshaped1D, enableVINRestrictions, enableComposite, multicodeCachingEnabled, upcEanDeblur

New JavaScript API Methods

New methods give developers more control and observability in their web barcode scanning implementation:

• getEnabledDecoders()

• setRoiOverlayBackgroundColor(), getRoiOverlayBackgroundColor()

• setLocationInImageResultEnabled(), isLocationInImageResultEnabled()

Now With Full TypeScript Support!

We've added TypeScript typings for all core APIs and new methods—ensuring better IntelliSense, type safety, and easier integration for modern JavaScript apps.
