Pocket Pascal

A minimal, installable Progressive Web App that renders "Hello, World!" and reads/writes a visit counter in SQLite via a small Express backend.

• Frontend: Vite + React + TypeScript + Tailwind v4 + shadcn/ui
• Backend: Express + TypeScript + better-sqlite3
• PWA: installable on Android (Chrome) and iOS (Safari), works offline

Quick start

pnpm install
pnpm dev

Open http://localhost:5173. The Vite dev server proxies /api to the backend on port 3001, and the visit counter increments on each load (proving the SQLite round-trip).

Production / install test

pnpm build
pnpm start

Open http://localhost:3001 — the backend serves the built client. Use DevTools → Application → Manifest to confirm PWA installability, then "Add to Home Screen". (On a real device, off localhost, HTTPS is required.)

Scripts

Command	Description
pnpm dev	Run client + backend concurrently
pnpm build	Build both packages
pnpm start	Run the production backend (serves the client)
pnpm lint	Lint all packages
pnpm typecheck	Type-check all packages
