Turborepo (pnpm workspaces) with all dependencies pinned to latest mutually-compatible versions: turbo 2.9, TypeScript 6, Fastify 5, React 19, Vite 8, better-sqlite3 12 + Drizzle ORM 0.45. Layout: - apps/server Fastify backend (local JWT auth + role guard, /health) - apps/web React 19 + Vite 8 operator SPA - packages/db Drizzle schema on SQLite/WAL; append-only events + users - packages/devices reader/printer/relay adapter interfaces (intent-only relay) - packages/shared shared domain types Architecture constraints from the design wiki are encoded in the scaffold: append-only hash-chained + signed event log, device-agnostic adapters, "a barrier is not a door" (relay expresses intent only), fully-local offline-first auth. wiki/ is an LLM-maintained Obsidian knowledge base (28 pages) ingested from the architecture & design notes, with its own maintenance schema. Verified: pnpm install, full turbo build (5/5), server boots and serves /health, drizzle-kit generates the initial migration.

# Technology Stack
|
|
|
|
The standing stack for the parking system. Every choice is **MIT/Apache/BSD** — a deliberate
|
|
constraint to avoid vendor lock-in and license rug-pulls (see [[payload-cms]] for the
|
|
cautionary case). (See [[parking-system-architecture]] §2.)

## Why these
|
|
|
|
One language end-to-end (Node), a mature ecosystem for device I/O (`serialport`, `node-hid`,
|
|
`escpos`), and a database whose only real limit (single-writer) a parking workload never
|
|
approaches. The stack is shaped by [[offline-first]]: nothing depends on a network at runtime.
