- Node/Express/TypeScript API under /api/v1 with JWT auth (login, refresh, logout, /me)
- Prisma schema: vendors, users, roles, products, categories, taxes, transactions
- SQLite for local dev; Postgres via docker-compose for production
- Full CRUD routes for vendors, users, categories, taxes, products with Zod validation and RBAC
- Paginated list endpoints scoped per vendor; refresh token rotation
- React/TypeScript admin SPA (Vite): login, protected routing, sidebar layout
- Pages: Dashboard, Catalog (tabbed Products/Categories/Taxes), Users, Vendor Settings
- Shared UI: Table, Modal, FormField, Btn, PageHeader components
- Multi-stage Dockerfile; docker-compose with Postgres healthcheck
- Seed script with demo vendor and owner account
- INSTRUCTIONS.md, ROADMAP.md, .claude/launch.json for dev server config

+
+Prisma Client JS is an **auto-generated query builder** that enables **type-safe** database access and **reduces boilerplate**. You can use it as an alternative to traditional ORMs such as Sequelize, TypeORM or SQL query builders like knex.js.
+
+It is part of the [Prisma](https://www.prisma.io/) ecosystem. Prisma provides database tools for data access, declarative data modeling, schema migrations and visual data management. Learn more in the main [`prisma`](https://github.com/prisma/prisma/) repository or read the [documentation](https://www.prisma.io/docs/).
