System Requirements Document (SRD) for jolly-hi

1. Introduction

The jolly-hi project aims to create a Flutter-based mobile application designed to foster a supportive and engaging community for mothers. The app will leverage GetStream.io to provide seamless, real-time activity feeds and chat infrastructure, ensuring a reliable and delightful user experience. This document outlines the system requirements for the development of the jolly-hi platform, with a focus on high-scale social interactions and leveraging AI to enhance functionality.

This SRD has been tailored for Vishal Khatri, based in India (IN), and assumes locale-specific defaults such as IST (Indian Standard Time) and INR (Indian Rupee) for currency.

2. System Overview

The jolly-hi app is a maternal community platform designed to connect mothers through real-time activity feeds and chat. It will serve as a digital "village" where users can find support, advice, and community. The app will be built using Flutter for cross-platform compatibility, with a backend powered by Python and FastAPI. The core features will be powered by GetStream.io, ensuring high-performance social feeds and messaging.

Key objectives:

• Provide a seamless and reliable user experience for real-time interactions.
• Leverage AI to enhance app functionality and development efficiency.
• Create a scalable and robust infrastructure to support a growing user base.

3. Functional Requirements

• As a User, I should be able to create a profile with personal details and preferences.
• As a User, I should be able to view and interact with activity feeds in real-time.
• As a User, I should be able to send and receive real-time messages through chat.
• As a User, I should be able to receive notifications for new messages, interactions, and updates.
• As a User, I should be able to search and connect with other users based on shared interests or location.
• As an Admin, I should be able to moderate content and manage user accounts.
• As a Developer, I should be able to leverage AI to optimize app performance and streamline development tasks.

4. User Personas

1. User (Mother)

• Primary user of the app.
• Needs: Real-time connection with other mothers, access to community support, and a seamless user experience.
• Goals: Build a support network, share experiences, and seek advice.

5. Visuals Colors and Theme

The jolly-hi app will use a warm and inviting color palette to create a sense of comfort and community. Suggested colors:

• Primary Color: Soft Coral (#FF6F61) – Represents warmth and connection.
• Secondary Color: Light Peach (#FFDAB9) – Adds a gentle, nurturing tone.
• Accent Color: Mint Green (#98FF98) – Symbolizes growth and positivity.
• Background Color: Off-White (#FDF5E6) – Ensures readability and a clean design.

Typography:

6. Signature Design Concept

Interactive Village Map Homepage

The jolly-hi app's landing page will feature an interactive village map that visually represents the community. The map will include:

• Animated Houses: Each house represents a community feature (e.g., chat, feeds, resources). Users can tap on a house to "enter" that section.
• Dynamic Day/Night Cycle: The map's background will shift between day and night based on the user's local time, creating a personalized experience.
• Micro-Interactions: Subtle animations like birds flying, trees swaying, and lights turning on/off in the houses will make the map feel alive.
• Customizable Avatars: Users can create avatars that appear walking around the village, fostering a sense of belonging.

This concept will make the app's homepage unforgettable, engaging, and reflective of the community spirit.

7. Non-Functional Requirements

• Performance: The app must handle at least 10,000 concurrent users without performance degradation.
• Scalability: The system should be scalable to accommodate future growth in user base and features.
• Reliability: Ensure 99.9% uptime for real-time feeds and chat.
• Security: Implement robust security measures to protect user data and privacy.
• Localization: Support for Indian languages and IST timezone.
