System Requirements Document (SRD)

Project Name: misty-ecommerce

1. Introduction

The purpose of this document is to outline the system requirements for misty-ecommerce, a comprehensive clothing e-commerce platform being developed using the MERN stack (MongoDB, Express, React, Node.js). The platform will cater to buyers, sellers, and administrators, providing a seamless shopping experience, robust seller management, and efficient backend operations.

This document will serve as a roadmap for the development of the platform, ensuring alignment across the frontend, backend, and admin panel layers. The platform will support multi-vendor functionality, enabling multiple sellers to list and manage their products while buyers enjoy a unified shopping experience.

Given the project's scope, the document also addresses architectural decisions, trade-offs, and deployment strategies to ensure scalability and maintainability.

2. System Overview

The misty-ecommerce platform will consist of three primary layers:

1. Frontend (React):

   • A user-facing interface for buyers to browse products, manage carts, and complete purchases.
   • A vendor-facing portal for sellers to manage their product listings and view analytics.

2. Backend (Node.js/Express/MongoDB):

   • A robust API layer to handle authentication, product management, order processing, and multi-vendor logic.
   • Integration with payment gateways (Stripe/PayPal) and image hosting services (Cloudinary/S3).

3. Admin Panel:

   • A dashboard for administrators to manage users, sellers, products, and platform analytics.

The system will support:

• Product catalog with size/color variants, filtering, and search.
• Shopping cart and checkout flow.
• User authentication and account management.
• Order tracking and history.
• Product reviews and ratings.
• Multi-vendor support with seller-specific dashboards.
• Payment gateway integration (Stripe/PayPal).

3. Functional Requirements

As a Buyer:

• I should be able to browse products with size and color variants.
• I should be able to filter and search for products by category, price, and ratings.
• I should be able to add products to a shopping cart and proceed to checkout.
• I should be able to track my orders and view order history.
• I should be able to leave reviews and ratings for purchased products.

As a Seller:

• I should be able to register as a seller and manage my product listings.
• I should be able to view my sales performance and earnings.
• I should be able to track orders placed for my products.
• I should be able to upload product images and manage inventory.

As an Admin:

• I should be able to approve or reject seller registrations.
• I should be able to moderate product listings and reviews.
• I should be able to view platform-wide analytics (e.g., total sales, vendor performance).
• I should be able to manage user accounts and resolve disputes.

4. User Personas

1. Buyer:

   • Primary user of the platform.
   • Browses products, adds items to the cart, and completes purchases.

2. Seller:

   • Vendor who lists products on the platform.
   • Manages inventory, tracks sales, and views earnings.

3. Admin:

   • Oversees platform operations.
   • Manages users, sellers, and product listings.

5. Visuals Colors and Theme

The misty-ecommerce platform will adopt a modern, clean, and vibrant design to enhance user engagement.

• Primary Colors:

  • Misty Blue (#89CFF0)
  • Midnight Blue (#003366)

• Accent Colors:

  • Coral (#FF6F61)
  • Soft Yellow (#FFD700)

• Neutral Colors:

  • White (#FFFFFF)
  • Light Gray (#F5F5F5)
  • Dark Gray (#333333)

The theme will focus on simplicity and elegance, ensuring a seamless user experience across all devices.

6. Signature Design Concept

Interactive Fabric Swatch Homepage:
The homepage will feature a dynamic fabric swatch interface where users can "touch" and explore different textures and patterns.

• Visuals:

  • A full-screen interactive grid of fabric swatches (e.g., denim, cotton, silk).
  • Hovering over a swatch reveals a zoomed-in texture with product recommendations.

• Animations:

  • Smooth transitions between swatches.
  • Micro-interactions like rippling effects when a swatch is clicked.

• User Interaction:

  • Clicking a swatch filters the product catalog by fabric type.
  • A "Featured Products" carousel dynamically updates based on the selected swatch.

This concept will create a tactile and immersive experience, making the platform memorable and engaging.

7. Non-Functional Requirements

• Performance:

  • The platform should handle up to 10,000 concurrent users.
  • API response times should not exceed 300ms under normal load.

• Scalability:

  • The system should support the addition of new vendors and products without significant performance degradation.

• Security:

  • All sensitive data (e.g., passwords, payment details) must be encrypted.
  • Role-based access control to prevent unauthorized actions.

• Availability:

  • The platform should maintain 99.9% uptime.

• Localization:

  • Support for INR currency and Indian timezone (IST).

8. Tech Stack

Frontend:

• React
• Redux or React Query
• Axios
