What it is
A multi-tenant marketplace. Vendors sign up, list products, and manage their own orders; buyers shop across all vendors in one cart.
Multi-tenancy and background work
The authorisation model is the crux: every query must be scoped to a vendor, and a missed scope leaks another seller’s data. Clerk handles identity while the Prisma layer enforces vendor scoping on access paths.
Order processing runs through Inngest rather than inline in the request. Payouts, notifications, and inventory decrements are durable, retryable steps — an email provider timing out doesn’t fail a customer’s checkout.
State is coordinated with Redux Toolkit, and vendor-facing analytics render with Recharts.
Notes
TODO: Document how vendor scoping is enforced — middleware, Prisma extension, or per-query. It’s the most interesting thing in this codebase.
