System Requirements Document (SRD)

Project Name: prism-ecommerce

1. Introduction

Welcome to the System Requirements Document (SRD) for prism-ecommerce, an innovative e-commerce platform designed to deliver a seamless online shopping experience. This document outlines the functional and non-functional requirements, design elements, and technical specifications necessary to create a modern, user-friendly, and visually appealing online store.

The goal of prism-ecommerce is to mimic real-world platforms like Amazon or Flipkart while incorporating unique design elements and features tailored to the needs of users in India (IN). The platform will support INR (₹) as the default currency and adhere to locale-specific preferences such as payment methods and shopping behaviors.

This document serves as a blueprint for the development team to ensure the successful implementation of the project.

2. System Overview

prism-ecommerce is a fully functional e-commerce website that provides users with an interactive and engaging shopping experience. The platform will include features such as product browsing, filtering, sorting, and dynamic cart functionality. It will also offer responsive design for both mobile and desktop users, ensuring accessibility across devices.

Key highlights of the system include:

• A visually appealing homepage with hero banners, featured products, and trending items.
• Comprehensive product listing and detail pages with realistic data.
• Shopping cart and checkout functionality with dynamic pricing and coupon application.
• User authentication UI for login and signup.
• Dark mode toggle for enhanced user experience.

The platform will use JavaScript for dynamic functionality and localStorage for cart data persistence. A realistic dataset of 20–30 products will be randomly generated across categories such as Electronics, Fashion, and Home.
