## What it is
A lightweight, zero-dependency JavaScript/TypeScript library for scanning QR codes and barcodes in the browser using the device camera or local files. It offers both an end-to-end scanner UI (Html5QrcodeScanner) and low-level APIs (Html5Qrcode) for building custom interfaces.

## Use cases
- scan qr codes from the browser camera
- add barcode scanning to a web app
- decode qr codes from uploaded image files
- build a custom qr scanner ui in javascript
- read barcodes on mobile and desktop browsers
- integrate code scanning into a web page with minimal code

## When to choose
- you need browser-based QR/barcode scanning with camera or file input
- you want a lightweight, dependency-free library that works across platforms and browsers
- you want a ready-made scanner UI in under ten lines of code

## When to avoid
- you need active bug fixes or new features - the project is in maintenance mode and seeking new owners
- you need native mobile app scanning rather than web
- you need server-side or offline-native code decoding

## Facets
