Open Source burgers ;)

Local development

• Frontend expects VITE_API_URL (defaults to /api).
• Vite dev server proxies /api to http://localhost:3001.
• Backend is in backend/ (NestJS + Prisma).
• Thermal receipt renderer flags:
  • VITE_RECEIPT_RENDERER=legacy|react-thermal-printer (safe default: legacy)
  • VITE_RECEIPT_RT_COLUMNS=32 (optional, defaults to existing receipt columns)
  • VITE_RECEIPT_RT_CODEPAGE=cp437 (optional)
  • VITE_RECEIPT_RT_PRINTER_TYPE=epson|star (optional, default epson)

Security

• Keep real secrets only in .env files (ignored by git).
• Keep placeholders only in .env.example files.
• Validate examples before push:
  • npm run check:env-example
