misty-ecommerce

byDevops Ninegravity

You are a senior full-stack software architect with deep expertise in e-commerce systems. I am building a complete clothing e-commerce website from scratch using the **MERN stack (MongoDB, Express, React, Node.js)**. I am at the very beginning โ€” I need a full roadmap and architecture plan across three layers: **frontend**, **backend**, and **admin panel**. ## Project Requirements The platform must support: - Product catalog with size/color variants, filtering, and search - Shopping cart and full checkout flow - User authentication and account management - Order tracking and history - Product reviews and ratings - Payment gateway integration (Stripe and/or PayPal) - **Multi-vendor / seller support** (multiple sellers listing products on the platform) ## What I Need From You For each of the three layers โ€” **Frontend (React)**, **Backend (Node.js/Express/MongoDB)**, and **Admin Panel** โ€” provide: - Recommended packages and modules with `npm install` commands - Core features specific to this clothing e-commerce context (including multi-vendor logic) - A suggested folder/project structure - Key third-party integrations (Stripe/PayPal, image hosting, email, etc.) ## Architecture Decisions to Flag Where I'll need to make a call, walk me through the tradeoffs rather than deciding for me. This includes: - Multi-vendor architecture patterns (shared vs. isolated seller data models) - Monolith vs. modular structure for this scale - Image storage strategy (Cloudinary vs. S3 vs. self-hosted) - Authentication approach (JWT vs. sessions, seller vs. buyer roles) - Deployment options suited for a first launch ## Approach Start with a **high-level system overview** showing how the three layers connect and where multi-vendor complexity lives. Then walk through each layer in depth. Treat this as a collaborative planning session โ€” after your initial breakdown, ask me clarifying questions to tailor the architecture to my specific scale, budget, and deployment preferences.

Implement Auth API

To Do

As a user, I want to use the backend auth API so that I can register, login, and receive a JWT token with my role (buyer, seller, admin) for secure access to protected routes. Implement POST /api/auth/register, POST /api/auth/login, POST /api/auth/refresh-token, POST /api/auth/logout. Include bcrypt password hashing, JWT signing with role claims, and refresh token rotation. Role-based middleware (isBuyer, isSeller, isAdmin) for protecting routes.

Implement Theme & Design System

To Do

As a frontend developer, I want to implement the global theme and design system for misty-ecommerce so that all pages share consistent colors, typography, and component styles. Set up CSS custom properties and global styles based on the SRD: Primary Misty Blue (#89CFF0), Midnight Blue (#003366), Coral (#FF6F61), Soft Yellow (#FFD700), White, Light Gray, Dark Gray. Configure Inter font, reusable button variants (filled, ghost), card surfaces, glassmorphism utilities, and the signature fabric-texture diagonal noise overlay. Remove any scaffold pages not needed (welcome page, generic dashboard pages not in the user flow). This task is independent and must be completed first.
