Fashion Corner

A multi-vendor modest-fashion platform delivered as three coordinated repositories — a NestJS/Prisma API, an admin console, and a next-intl storefront — built around store settlements, warehouse-level stock reservations and a backend-for-frontend auth layer.

Several partner stores sell through one platform. Each needs its own inventory, stock settlement and fulfilment tracking; customers need a storefront that is genuinely bilingual — English and Arabic, including right-to-left layout.

Selling on behalf of multiple stores means stock can’t be a single number and money can’t be a single ledger. The platform has to know which warehouse holds a unit, hold it while a customer checks out, and track what the platform owes each partner store after commission.

A NestJS/Prisma API models warehouses, locations, reservations and stock transactions alongside per-store agreements and settlements. An admin console manages stores, catalog, orders, coupons and settlements. A next-intl storefront delivers cart, wishlist, coupons, reviews and checkout in both languages. The two Next.js apps talk to the API through a backend-for-frontend layer so raw JWTs never reach the browser.

1. A

   Backend-for-frontend authentication

   Both Next.js apps proxy API calls through their own server routes, so the browser holds a session rather than a bearer token. It removes a whole class of token-theft issues most storefronts accept by default.

2. B

   Reservations, not just stock counts

   Inventory is tracked per warehouse and location, with explicit reservations and stock transactions — so a unit in a customer’s checkout isn’t sold twice, and every movement is auditable.

3. C

   Settlement as a first-class model

   Store agreements and settlements are modelled directly, making commission and payouts between the platform and each partner store a query instead of a spreadsheet.

4. D

   i18n from the routing layer up

   The storefront is locale-routed with next-intl, so Arabic isn’t a translation pass bolted on at the end — layout direction and content switch together.
