@scanlatch/sdk

Barcode scanning that runs entirely in the browser. Decode still images and live camera streams, or read grayscale scanlines directly — no pixel ever leaves the device.

Install

npm i @scanlatch/sdk

Quick start

import { createBrowserSdk } from '@scanlatch/sdk';

const sdk = createBrowserSdk({ key: accountKey });
await sdk.initialize();

// still images
const decoder = await sdk.createDecoder();
const results = await decoder.decode(file, { symbologies: ['qr', 'ean13'] });

// live camera
const scanner = sdk.createCameraScanner(video, { onDetections: show });
await scanner.start();

sdk.destroy();
