| 2 | +# 📦 Scan Multiple Barcodes Samples |
| 3 | + |
| 4 | +## 🚀 1. Hello World |
| 5 | + |
| 6 | +This sample demonstrates how to use the `BarcodeScanner` API from the [Dynamsoft Barcode Reader JavaScript SDK](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/) to scan **multiple barcodes continuously** from a video stream in a web application. |
| 7 | + |
| 8 | +### ✨ Features |
| 9 | + |
| 10 | +- Scan multiple 1D/2D barcodes |
| 11 | +- Live video decoding using `BarcodeScanner` component |
| 12 | +- Easy integration into your web application |
| 13 | +- UI rendered into a customizable container |
| 14 | + |
| 15 | +### 🔧 How It Works |
| 16 | + |
| 17 | +The sample uses the `BarcodeScanner` class to launch a scanner and decode barcodes from a camera stream. The key configuration includes: |
| 18 | + |
| 19 | +- **License Key** – Required to activate the SDK. |
| 20 | +- **`engineResourcePaths`** – Points to required resources hosted on a CDN or locally. |
| 21 | +- **UI container** – An HTML element where the scanner is rendered. |
| 22 | + |
| 23 | +```ts |
| 24 | +const config = { |
| 25 | + license: "YOUR-LICENSE-KEY", |
| 26 | + engineResourcePaths: { |
| 27 | + // feel free to change it to your own path |
| 28 | + rootDirectory: "https://cdn.jsdelivr.net/npm/dynamsoft-barcode-reader-bundle@10.5.1000/dist/", |
| 29 | + }, |
| 30 | + container: ".barcode-scanner-view", |
| 31 | + scanMode: Dynamsoft.EnumScanMode.SM_MULTI_UNIQUE, |
| 32 | + showResultView: true, |
| 33 | + showUploadImageButton: true, |
| 34 | + scannerViewConfig: { |
| 35 | + showCloseButton: true |
| 36 | + }, |
| 37 | +}; |
| 38 | +``` |
| 39 | + |
| 40 | +The BarcodeScanner instance is created and launched like this: |
| 41 | + |
| 42 | +```ts |
| 43 | +const barcodeScanner = new Dynamsoft.BarcodeScanner(config); |
| 44 | +barcodeScanner.launch(); |
| 45 | +``` |
| 46 | + |
| 47 | +### 📌 Notes |
| 48 | + |
| 49 | +- This sample scans **multiple unique barcodes**, you can configure `scanMode` to change the behavior to scan one single barcode. |
| 50 | +- To avoid network-related loading issues, consider hosting all required resources locally. |
| 51 | + |
| 52 | +## 🛒 2. Cart Builder |
| 53 | + |
| 54 | +This sample simulates a shopping experience where users scan barcodes to add items to a dynamic cart. |
| 55 | + |
| 56 | +### ✨ Features |
| 57 | + |
| 58 | +- Scan multiple 1D/2D barcodes |
| 59 | +- Live video decoding using `BarcodeScanner` component |
| 60 | +- Floating and draggable scanner window. |
| 61 | +- Dynamic cart updates on each scan. |
| 62 | + |
| 63 | +### 🔧 How It Works |
| 64 | + |
| 65 | +The scanning logic mirrors the Hello World sample, but scanned results populate the cart instead of just displaying in the result view. |
| 66 | + |
| 67 | +The UI features a "Scan Barcode" button, a styled cart, and basic interactivity with vanilla JavaScript and CSS. |
| 68 | + |
| 69 | +A list of 20 dummy products is used, with each scan randomly adding a product to the cart showing its name, shortened barcode, and price. |
| 70 | + |

| 72 | + |
| 73 | +Multiple samples are provided for single barcode scanning. These samples can be easily adapted to scan multiple unique barcodes by simply updating the `config` object. |
