PROJECT REQUIREMENTS DOCUMENT (PRD)
Project Title: Cloud-Deployed Real-Time Collaborative TODO Board
Deployment Model: PaaS Cloud Deployment using Render

--------------------------------------------------
1. PROJECT OVERVIEW
--------------------------------------------------

The Real-Time Collaborative TODO Board is a web-based application that allows multiple users
to create and manage tasks collaboratively in real time.

Users can add, edit, delete, and organize tasks while all connected users see updates
instantly through WebSocket communication.

The primary objective of this project is to demonstrate cloud deployment of a real-time
web application using a Platform-as-a-Service (PaaS) cloud platform.

The application will be deployed on Render cloud infrastructure, making it accessible
through a public URL over the internet.

This project demonstrates:

- Real-time web communication
- Multi-user collaboration systems
- Cloud application deployment
- WebSocket-based synchronization
- Modern web hosting workflows using GitHub + cloud platform

--------------------------------------------------
2. PROJECT OBJECTIVES
--------------------------------------------------

- Deploy a web application on a cloud platform.
- Demonstrate real-time synchronization using WebSockets.
- Build a collaborative multi-user task management system.
- Understand the PaaS deployment model.
- Implement a modern deployment pipeline using GitHub and Render.
- Demonstrate public cloud access to an application.

3. FEATURES

CORE FEATURES

1. Create / Edit / Delete Tasks
Users can create new tasks, modify tasks, and delete tasks from the board.
Changes synchronize instantly across all connected users.

2. Multiple Lists / Boards
Tasks can be organized into different lists such as Work, Personal, or Urgent.

3. Drag and Drop Tasks
Tasks can be moved between lists using drag-and-drop functionality.

4. Task Assignment
Tasks can be assigned to specific users.

5. Due Dates
Tasks can include deadlines with visual indicators.

6. Priority Levels
Tasks can be tagged as High, Medium, or Low priority.

7. Real-Time Updates
All task changes are synchronized instantly using WebSockets (Socket.IO).

--------------------------------------------------
ADVANCED FEATURES (OPTIONAL / FUTURE SCOPE)

8. Comments / Notes on Tasks
9. User Presence Indicator (who is online)
10. Sharing and Permissions (public/private boards)
11. Undo / Redo functionality
12. Search and Filter tasks
13. Dark Mode interface
14. Export tasks as CSV / JSON

--------------------------------------------------
5. SYSTEM ARCHITECTURE

User Browser
      |
      | HTTP / WebSocket
      |
Frontend Application
      |
      | Socket.IO
      |
Node.js + Express Server
      |
Render Cloud Platform
      |
Public Internet URL

Users interact with the application through a browser.
The backend server broadcasts updates to all connected clients using WebSocket events.

--------------------------------------------------
6. IMPLEMENTATION STEPS

Step 1 – Environment Setup

Install Node.js and npm.

Initialize project:

npm init -y
npm install express socket.io

Step 2 – Backend Development

Create Express server.
Integrate Socket.IO.

Implement events for:
- addTask
- deleteTask
- updateTask

Step 3 – Frontend Development

Build a simple interface including:
- Task input field
- Task list display
- Add/Delete buttons
- Multiple lists UI

Connect frontend to backend using Socket.IO client.

Step 4 – Real-Time Logic

User action → event sent to server
Server processes event
Server broadcasts update
All clients update UI instantly

Step 5 – Local Testing

Run server locally:

node server.js

Open multiple browser tabs to confirm real-time synchronization.

Step 6 – Cloud Deployment

1. Create GitHub repository
2. Push project code to GitHub
3. Create Render account
4. Connect GitHub repository to Render
5. Configure deployment settings
6. Deploy the application

Render automatically builds and runs the application.

--------------------------------------------------
7. CLOUD ACCESS

After deployment the application will be accessible through a public URL:

https://project-name.onrender.com

Users from anywhere can access the collaborative board.

--------------------------------------------------
8. PROJECT REQUIREMENTS

Software Requirements
Node.js
npm
Git
Web Browser

Cloud Requirements
Render account
GitHub account

Hardware Requirements
Laptop
Internet connection

--------------------------------------------------
9. EXPECTED OUTCOME

Users will be able to collaborate on a shared TODO board in real time.
Multiple users will see task updates instantly.
The application will be publicly accessible via a cloud-hosted URL.

This demonstrates:

- Real-time communication systems
- Multi-user application architecture
- Cloud deployment using PaaS
