1. Overall shape

ReSell Hub is organized as a Next.js App Router application. The repository is primarily the frontend + route handlers for a second-hand marketplace, with a clear split between public marketplace pages, authentication endpoints, and role-based dashboards.

2. Route structure and page shells

The app uses two major layout boundaries:

- src/app/(mainLayout) for the public storefront

- src/app/dashboard for authenticated, role-specific areas

This makes the architecture easy to diagram as two top-level user experiences sharing the same codebase but different layouts and navigation.

3. Public marketplace experience

The public side includes:

- Home page with featured products, marketplace stats, popular categories, and sustainability messaging

- Products listing and product detail pages

- Categories page

These pages are the discovery layer where buyers browse and evaluate inventory before logging in or purchasing.

4. Authentication and session boundary

Authentication is handled through Better Auth:

- src/app/api/auth/[...all]/route.js exposes the auth API surface

- src/app/api/verify-session/route.js is a dedicated session-check endpoint

- src/lib/auth.js and src/lib/auth-client.js centralize auth setup

This creates a distinct boundary between anonymous browsing and protected app areas.

5. Role-based dashboard architecture

The dashboard is split into three user roles:

- Buyer: orders, payments, profile, wishlist

- Seller: add product, manage products, manage orders, analytics, profile

- Admin: analytics, orders, products, users

src/app/dashboard/layout.js and src/components/dashboard/Sidebar.jsx indicate a shared dashboard shell with role-specific navigation and page content underneath.

6. Seller workflow

Seller pages support the supply side of the marketplace:

- Adding products

- Editing own products

- Managing listings and orders

- Viewing seller analytics

The README’s feature list implies image upload via ImgBB, so product creation likely includes media upload as part of the listing flow.

7. Buyer workflow

Buyer pages focus on purchase tracking and saved items:

- Wishlist management

- Orders

- Payments

- Profile

The checkout flow is split out into dedicated pages under src/app/checkout, with a separate success screen, which suggests a transaction lifecycle that starts from product/cart selection and ends with payment confirmation.

8. Admin workflow

The admin section is built around marketplace governance:

- Product approval/management

- Order oversight

- User management

- Analytics

This implies a moderation boundary where seller-submitted inventory can be reviewed before becoming visible in the public catalog.

9. Data access and secure client calls

src/lib/axiosSecure.js suggests a shared, authenticated HTTP client for protected API calls. In architecture terms, this is the main client-side data access layer used by dashboard and transactional pages to talk to backend services while carrying auth context.

10. External service integration

The README shows the platform depends on a few external systems that materially shape the architecture:

- Stripe for payments

- Better Auth for login and session management

- ImgBB for image hosting

- A backend stack based on Express + MongoDB is referenced in the README, implying the frontend likely consumes a separate API/service layer for marketplace data

11. UI composition and shared presentation

The app uses reusable UI components for the storefront and marketing surface:

- Navbar, Footer, HeroBanner, SustainabilityImpact

- Home-page feature sections such as stats and popular categories

This keeps the public experience modular while the dashboard has its own reusable shell elements.

12. Nonfunctional concerns

The stack emphasizes:

- responsive UI

- animation via Framer Motion

- analytics visualization via Recharts

- search/filter/sort and pagination for browsing efficiency

These are not separate subsystems, but they influence how data is presented and how the marketplace scales in the UI.

13. How the main flows connect

The end-to-end architecture is:

public browsing → authentication/session verification → role-based dashboard → product creation/approval → checkout/payment → order tracking/analytics.

That flow is the core diagram to draw, with auth and secure API access as the central boundary between the public storefront and protected marketplace operations.
