    paper MERN E-commerce

    Vybe is a full-stack e-commerce app built on the MERN stack. It supports product browsing with search and pagination, cart/checkout, order placement with PayPal-style payments, user auth with role-based admin features, and admin dashboards for products/orders/users. The backend serves a REST API with JWT-secured routes, file uploads, and MongoDB persistence; the frontend is a React SPA using Redux Toolkit Query for data fetching and caching.

    Tech Stack
    MongoDB + Mongoose – document database and schema modeling for products, users, and orders.
    Express + Node.js – REST API, middleware, uploads, and auth.
    React + React Router – SPA UI, routing, and protected admin/user pages.
    Redux Toolkit Query – data fetching/caching, optimistic updates, and tag-based invalidation.
    Bootstrap/React-Bootstrap – responsive UI components.
    Multer – product image uploads.
    JSON Web Tokens + cookies – auth and session.
    PayPal client integration endpoint – payment processing (swap in your provider).
