# CLAUDE.md
|
||
|
||
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
|
||
|
||
## Project Overview
|
||
|
||
A browser-based QR code label generator for Paperless-ngx Archive Serial Numbers (ASN). The entire application is a single `index.html` file with no build process.
|
||
|
||
## Development
|
||
|
||
**No build tools required** - Open `index.html` directly in a browser or serve it with any static file server.
|
||
|
||
The application uses CDN-hosted dependencies:
|
||
- TailwindCSS (with forms and typography plugins)
|
||
- AlpineJS 3.x
|
||
|
||
## Architecture
|
||
|
||
Single-page application using AlpineJS for reactivity. Key structure in `index.html`:
|
||
|
||
- **`qrCodeApp()`** (line 255): AlpineJS component containing all application state and logic
|
||
- `generateLabels()`: Creates label data array with QR code URLs via external API (api.qrserver.com)
|
||
- `printLabels()`: Triggers browser print dialog
|
||
- Generates 189 labels per sheet (7 columns × 27 rows)
|
||
|
||
- **Print styling**: Uses CSS `@page` rule for A4 paper with zero margins (requires Chrome/Chromium)
|
||
|
||
- **Label format**: Hardcoded for Avery L4731 labels (see specifications below)
|
||
|
||
