Introduction

This document outlines the system requirements for the Ecommerce project. The goal of this project is to create a comprehensive ecommerce platform tailored to the needs of users in India, with features such as login/signup functionality and a dynamic landing page.

System Overview

The Ecommerce project aims to provide a seamless online shopping experience for users. It will include essential ecommerce functionalities such as product browsing, shopping cart management, secure checkout, and user account management. The platform will be designed to accommodate the local preferences and requirements of Indian users, including currency and timezone settings.

Functional Requirements

• As a User, I should be able to log in to my account using my credentials.
• As a User, I should be able to browse products by categories.
• As a User, I should be able to add products to a shopping cart.

User Personas

• User: An individual who has registered on the platform and can log in to access personalized features.
• Guest: An individual who can browse products without logging in but cannot make purchases or access personalized features.

Core User Flows

• User signs up -> User logs in -> User browses products -> User adds products to cart -> User checks out -> User logs out
• Guest browses products -> Guest views product details

Visuals Colors and Theme

• primary: #1A73E8 (a vibrant blue for brand identity)
• primary_light: #E8F0FE (a lighter blue for hover states)
• secondary: #FF7043 (a warm coral for emphasis)
• accent: #34A853 (a bright green for CTAs and active states)
• highlight: #FBBC05 (a golden yellow for notifications and alerts)
• bg: #FFFFFF (a clean white background)
• surface: rgba(255, 255, 255, 0.9) (a subtle white for cards/panels)
• text: #202124 (a dark grey for primary text)
• text_muted: #5F6368 (a softer grey for secondary text)
• border: rgba(218, 220, 224, 0.5) (a light grey for borders)

Signature Design Concept

The Ecommerce platform will feature an interactive landing page designed to captivate users from the moment they arrive. The homepage will utilize a "Product Carousel" concept, where users can scroll horizontally through a series of featured products displayed in a 3D rotating carousel. Each product card will flip to reveal more details when hovered over, creating an engaging and dynamic browsing experience. This will be implemented using @react-three/fiber for 3D effects and framer-motion for smooth animations. Users can click on a product to view detailed information, adding an interactive layer to the shopping experience.

Interaction Model & Motion Direction

The landing page will adopt a "parallax" interaction model, providing a layered depth effect as users scroll. Decorative elements will move at different speeds to create a sense of depth, while core content remains in the natural flow. This approach will enhance the storytelling aspect of the landing page, making it visually rich and engaging.

Non-Functional Requirements

• The system should support high availability and scalability to handle peak loads during sales events.
• The platform must ensure data security and user privacy, complying with local regulations.
• The website should be responsive and accessible across various devices and screen sizes.

Tech Stack

• Backend: Python, FastAPI
• Database: MySQL or MariaDB, using Alembic for migrations
• Local orchestration: Docker, docker-compose
• Server-side orchestration: Kubernetes

Assumptions and Constraints

• The platform will primarily target users in India, with INR as the default currency.
• The system will be designed to handle a large catalog of products and high user traffic.
• User authentication will be managed securely with industry-standard practices.
