Quick Start

git clone https://github.com/devtechedge/luxe-tracker.git
cd luxe-tracker
bun install # or: npm install
bun run dev # → http://localhost:3000

No environment variables required.

Tests & CI

bun test# unit: snapshot counts, telemetry, price-history key split, VIP, validation
bun run typecheck
bun run test:e2e # Playwright Chromium — overview, Price Matrix nav, theme toggle

GitHub Actions runs unit + typecheck + e2e on every push to main. Dependabot opens weekly PRs for patch/minor npm and Actions updates (majors ignored).

Security

See SECURITY.md. Public demo has no backend, no env vars, and no auth boundary. Watchlist / alerts / spend in localStorage are allow-listed on read.

Architecture

Single Vercel deployment. All analytics are pure functions over a seeded in-memory snapshot (src/lib/data-snapshot.ts + src/lib/analytics.ts). Watchlist and alerts persist in localStorage. Dark/light theme is controlled by a no-flash inline script + CSS variables.

The same data shape was previously backed by Prisma + Supabase; the client-side version keeps the full panel surface while guaranteeing a permanent green live demo.

GitHub Actions runs unit + typecheck + e2e on every push to main. Dependabot opens weekly PRs for patch/minor npm and Actions updates (majors ignored).
Security
See SECURITY.md. Public demo has no backend, no env vars, and no auth boundary. Watchlist / alerts / spend in localStorage are allow-listed on read.
Architecture
Single Vercel deployment. All analytics are pure functions over a seeded in-memory snapshot (src/lib/data-snapshot.ts + src/lib/analytics.ts). Watchlist and alerts persist in localStorage. Dark/light theme is controlled by a no-flash inline script + CSS variables.
The same data shape was previously backed by Prisma + Supabase; the client-side version keeps the full panel surface while guaranteeing a permanent green live demo.
