# Feature Layer - Barcode Recognition - Web Edition (v11.x)

> Root Documentation: https://www.dynamsoft.com/barcode-reader/docs/llms.txt
> This Layer URL: https://www.dynamsoft.com/barcode-reader/docs/web/

This documentation covers Dynamsoft Barcode Reader SDK v11.x. It defines the Barcode Recognition Feature Layer APIs for the web (JavaScript) edition.

**Language Edition:**
- JavaScript: https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/

## LLM Guidance

- This layer provides barcode-specific result classes, enumerations, and the high-level BarcodeScanner UI for the JavaScript edition. It does NOT contain the main entry point (CaptureVisionRouter) - that is in the Workflow Layer.
- BarcodeScanner is a ready-to-use UI component that wraps CaptureVisionRouter + CameraEnhancer for quick barcode scanning integration with minimal code.
- DecodedBarcodesResult is the primary result class; BarcodeResultItem contains individual barcode data (text, bytes, format, location).
- SimplifiedBarcodeReaderSettings provides a quick configuration API; for full control, use JSON parameters from the Core Concepts & Parameter Layer.
- The JavaScript edition FAQ covers web-specific issues: HTTPS requirements, WASM loading, CDN deployment, camera permissions, iOS Safari compatibility, and offline mode.
- When explaining barcode reading workflows for JavaScript, combine CaptureVisionRouter (from Workflow Layer) with DecodedBarcodesResult (from this layer) and parameter configuration (from Core Concepts & Parameter Layer).
