System Requirements Document (SRD)

Project Name: pearl-amazon

1. Introduction

Welcome to the System Requirements Document (SRD) for pearl-amazon, an e-commerce application designed for Vansh Aggarwal's brand, Lutcia. This document outlines the functional and non-functional requirements, design concepts, and technical specifications necessary to create a fully functional marketplace app similar to Amazon.

The app will serve as a general marketplace for all kinds of items, providing a seamless shopping experience for customers and robust management tools for administrators. The goal is to develop a scalable, user-friendly platform that can be uploaded to the Play Store and cater to a wide audience in India and beyond.

• primary_light: #4A90E2 (Sky Blue)
• secondary: #FF6F61 (Coral Red)
• accent: #F4B400 (Golden Yellow)
• highlight: #FFAB40 (Amber Orange)
• bg: #F5F5F5 (Light Gray)
• surface: rgba(255, 255, 255, 0.9) (Soft White)
• text: #212121 (Dark Charcoal)
• text_muted: #757575 (Muted Gray)
• border: rgba(0, 0, 0, 0.1) (Subtle Black)

6. Signature Design Concept

Concept: Interactive Product Carousel with Dynamic Backgrounds

The homepage of pearl-amazon will feature an interactive product carousel that dynamically changes its background based on the category being viewed.

• Interaction: Users can swipe or click through featured product categories. Hovering over a category will trigger subtle animations, such as zoom effects or color shifts.
• Dynamic Backgrounds: Each category will have a unique animated background (e.g., flowing fabric for fashion, glowing circuits for electronics). These backgrounds will subtly morph as users navigate the carousel.
• Micro-interactions: Clicking on a product will expand it into a detailed view with smooth transitions powered by Framer Motion.
• Libraries:
  • Framer Motion: For spring physics and hover animations.
  • GSAP: For scroll-triggered transitions and dynamic background morphing.

This concept will create a visually stunning and interactive first impression, ensuring users are captivated from the moment they land on the app.

7. Interaction Model & Motion Direction

Landing Page Interaction Model: Parallax

The landing page will use a parallax interaction model to create layered depth and immersive storytelling.

• Decorative Layers: Atmospheric elements like floating particles, glowing gradients, and subtle animations will move at different speeds as users scroll.
• Content Flow: Real content (e.g., product categories, featured items) will scroll naturally, ensuring usability.
• Section Mechanics: Each section will feature a unique interaction, such as:
  • Category Highlights: Scroll-triggered zoom-ins on featured categories.
  • Customer Reviews: Kinetic typography animations.
  • Admin Tools Showcase: Interactive mockups of the admin panel.

Internal Pages Interaction Model: Static

For internal pages like dashboards, settings, and forms, the interaction model will prioritize clarity and minimal motion to enhance readability and efficiency.

8. Non-Functional Requirements

• Performance: The app must load within 2 seconds for 90% of users.
• Scalability: Support up to 1 million users and 500,000 product listings.
• Security: Implement robust encryption for user data and payment transactions.
• Availability: Ensure 99.9% uptime with failover mechanisms.
• Localization: Support Indian currency (INR) and regional languages.
