Scan DataMatrix Code

This sample demonstrates decoding DataMatrix barcodes from camera or image input using the Dynamsoft Barcode Reader (JavaScript edition).

Included files

• index.html — Demo page (camera & image input) and UI.
• ReadDataMatrix.json — Example configuration used by the sample.

Quick start

Opening HTML files directly may not work as expected. Instead, run a local development server. Here’s a quick method using Visual Studio Code:

1. Install the Five Server extension from the VS Code Marketplace.

2. Right-click on index.html and select "Open with Five Server". This will serve the application at http://127.0.0.1:5500/index.html.

3. Allow camera access when prompted and point the camera at a barcode.

What this sample shows

• Enabling DataMatrix decoding and related tuning.
• Tips for scanning small or dense DataMatrix symbols.
• Using a JSON template to configure decoder behavior.

Notes

• Run via HTTP(S) or localhost; opening files via file:// may break module loading or camera permissions.
• See the repository root README.md for general instructions and API documentation links.
