• JSON‑driven configuration:
  • Station list (Paytm A‑BRTS stops)
  • QR sizes and error‑correction levels
  • Optional presets
• Custom dropdowns with animated chevrons; keyboard friendly.
• Light/Dark/System theme via CSS variables.
• PNG download of the generated QR.
• Config validation with a clear error banner when public/input.json is invalid.
• Dockerized production image (Nginx) and compose file.

Demo

Build locally or deploy using the instructions below. After building, serve dist/ from any static host or run the provided Docker image.

Getting Started

Prerequisites

• Node.js 18+ (or Docker)
• npm

Install & Run (Development)

npm install
npm run dev
# open http://localhost:5173

Build (Production)

npm run build
# output in dist/

Lint/Format config (input.json)

npm run format:input
# pretty-prints public/input.json

Configuration

The application loads settings from public/input.json.

Example:

{
  "sizes": [
    { "label": "Small (128x128)", "value": 128 },
    { "label": "Medium (256x256)", "value": 256 },
    { "label": "Large (512x512)", "value": 512 }
  ],
  "errorCorrections": [
    { "label": "Low (L)", "value": "L" },
    { "label": "Medium (M)", "value": "M" },
    { "label": "Quartile (Q)", "value": "Q" },
    { "label": "High (H)", "value": "H" }
  ],
  "presets": [
    {
      "name": "A-BRTS Station A",
      "text": "Blank Data",
      "size": 512,
      "ecl": "H"
    },
    {
      "name": "A-BRTS Station B",
      "text": "Blank Data",
      "size": 512,
      "ecl": "H"
    },
    {
      "name": "A-BRTS Station C",
      "text": "Blank Data",
      "size": 512,
      "ecl": "H"
    }
  ]
}

Notes:

• If parsing or schema validation fails, an error banner appears and safe defaults load so the UI remains usable.
• Update stations under "stations". Validate/format via npm run format:input.

Theming

• “Menu” in the header toggles Light/Dark/System.
• All colors are driven by CSS variables on the root .app element.

Docker (Production)

Build and run:

docker compose up --build -d
# open http://localhost:8080

What’s included

• Multi‑stage Dockerfile (Node builder → Nginx runtime)
• docker-compose.yml (maps 8080→80)
• nginx.conf with SPA routing fallback and gzip

Deployment

Static hosting (recommended for SPAs)

• Cloudflare Pages / Netlify / Vercel / GitHub Pages
  • Build command: npm run build
  • Output directory: dist
  • Enable SPA fallback to index.html (provider setting or redirects file)
