grand-app System Requirements Document

Introduction

The purpose of this document is to outline the system requirements for the "grand-app," a website designed for a restaurant. The application will facilitate menu management, order processing, and billing operations. The project is tailored to meet the needs of restaurant staff and customers, ensuring a seamless and efficient dining experience.

System Overview

The grand-app is a web-based application designed to manage restaurant operations, including menu display, order processing, and billing. The application will be mobile-responsive and utilize local storage for data management, eliminating the need for a backend server. Images for menu items will be sourced from open-source websites to enhance the visual appeal of the application.

Functional Requirements

• As a Customer, I should be able to view the restaurant menu, including items like idli, poori, vada, dosa, and coffee.
• As a Customer, I should be able to add menu items to my cart by clicking on them.
• As a Customer, I should be able to view and manage my cart, including adding or removing items.
• As a Customer, I should be able to proceed to checkout and view the total bill.
• As a Customer, I should be able to pay using a QR code.
• As a Customer, I should be able to print the bill after payment.
• As a Customer, I should be able to clear the cart after completing an order.
• As a Staff Member, I should be able to manage orders and view sales reports.
• As a User, I should be able to view images of menu items sourced from open-source websites.
• As a User, I should experience a mobile-responsive design for ease of use on various devices.

User Personas

• Customer: Individuals visiting the restaurant who will interact with the menu, place orders, and make payments.
• Staff Member: Restaurant staff responsible for managing orders and viewing sales reports.

Core User Flows

• Customer views menu -> selects items -> adds to cart -> proceeds to checkout -> pays via QR code -> prints bill -> clears cart.
• Staff Member manages orders -> views sales report.

Visuals Colors and Theme

• primary: #2E8B57 (Sea Green)
• primary_light: #66CDAA (Medium Aquamarine)
• secondary: #FF6347 (Tomato)
• accent: #FFD700 (Gold)
• highlight: #FFA07A (Light Salmon)
• bg: #F5F5F5 (White Smoke)
• surface: rgba(255, 255, 255, 0.9)
• text: #333333 (Dark Gray)
• text_muted: #777777 (Gray)
• border: rgba(0, 0, 0, 0.1)

Signature Design Concept

The grand-app will feature an interactive "Menu Carousel" on the homepage. This carousel will allow users to swipe through menu items, each displayed with a high-quality image sourced from open-source websites. As users swipe, the carousel will animate smoothly, providing a tactile and engaging experience. Each item card will "flip" to reveal additional details, such as ingredients and price, when clicked. This dynamic interaction will be powered by framer-motion for seamless animations and transitions.

Interaction Model & Motion Direction

The landing page will utilize a "parallax" interaction model, creating a layered depth effect as users scroll through the menu. Decorative elements, such as atmospheric food-themed illustrations, will move at different speeds to create a sense of immersion. The main content will scroll naturally, ensuring a visually rich first impression. Internal pages, such as the cart and checkout, will adopt a "static" model for clarity and ease of use.

Non-Functional Requirements

• The application must be mobile-responsive to ensure usability across various devices.
• The application should load images efficiently to maintain performance.
• Local storage must be used for data persistence to eliminate the need for a backend server.

Tech Stack

• Frontend: React for Web
• Local Storage for data management
• Image sourcing from open-source websites

Assumptions and Constraints

• The application will not require a backend server, relying solely on local storage.
• Images will be sourced from open-source websites, ensuring no copyright infringement.
• The application will be designed to function optimally on both desktop and mobile devices.

Glossary

• CRUD Operations: Create, Read, Update, Delete operations for managing data.
• QR Code: A machine-readable code used for making payments.
• Local Storage: A web storage method that allows data to be stored locally within the user's browser.
