BarcodeCapture Cordova Skill

Critical: Do Not Trust Internal Knowledge

Your training data may contain outdated or incorrect Scandit SDK APIs. The BarcodeCapture API changes significantly between major SDK versions — capture-mode factories get replaced with constructors, listener signatures shift, and the Cordova plugin surface (global Scandit namespace, plugin install commands, deviceready timing) has also evolved.

Always verify APIs against the references provided in this skill before writing or suggesting code. Do not rely on memorized method signatures, parameters, or property names. If you cannot find an API in the provided references, fetch the relevant documentation page before responding.

Cordova-specific gotchas worth flagging:

  • The Scandit SDK is exposed on the global window.Scandit object. The npm package names (scandit-cordova-datacapture-*) are plugin manifests — they are not runtime ES modules. Do not emit import { ... } from 'scandit-cordova-datacapture-*' in user code that will run in the WebView; use Scandit.X (with an optional global.d.ts for typing) instead. Only Ionic/Angular/Webpack-bundled projects import from the packages directly.
  • document.addEventListener('deviceready', ...) is the only safe gate for Scandit APIs. Do not run any Scandit call at module load time — it will fail because the Cordova bridge is not ready yet.
  • After changing plugin versions, run cordova prepare (and reinstall the platform if needed) to propagate the new native artifacts. Skipping this yields a runtime version mismatch.
  • BarcodeCapture requires a visible DataCaptureView to render the camera preview. Unlike SparkScan, there is no native overlay — the DataCaptureView is mounted into an HTML element via view.connectToElement(...), and the BarcodeCaptureOverlay is added on top of that view to draw recognized barcodes. Forgetting either step is the most common reason "scanning works but I see nothing".
  • Inside the didScan callback, disable the mode (barcodeCapture.isEnabled = false) before doing any UI work that takes more than a frame — the listener blocks frame processing while it runs, so long-running work there freezes the camera and may cause duplicate scans.
