Product Requirements Document - FirstList Assignment

Overview

FirstList Assignment is a full-stack authentication and user management system built to demonstrate modern web development practices. The application features role-based access control, user management, and spoof checking functionality.

Current Architecture

Backend (Node.js/Express)

• Framework: Express.js with JWT authentication
• Database: MongoDB with Mongoose ODM
• Security: bcryptjs for password hashing, JWT for session management
• Validation: express-validator for input sanitization
• CORS: Enabled for cross-origin requests

Frontend (React/Vite)

• Framework: React 18 with Vite build tool
• Styling: Tailwind CSS for responsive design
• Routing: React Router for navigation
• Icons: Lucide React for UI icons
• State Management: React hooks (useState, useEffect)

Current Features (Implemented)

✅ Authentication System

• Login/Signup: User registration and authentication
• JWT Tokens: 24-hour token expiration
• Password Security: bcrypt hashing with salt
• Input Validation: Server-side validation for email/password

✅ User Management

• Role-Based Access: Admin, Agent, User roles
• User Creation: Admins can create new users
• Role Validation: Permission checks for user creation
• User Retrieval: Get users based on role permissions

✅ UI Components

• Login Page: Clean authentication form
• Signup Page: User registration interface
• User Management: Admin panel for user operations
• Responsive Design: Mobile-first approach with Tailwind

Missing Features (To Implement)

🔄 Dashboard System

• Landing Dashboard: Main dashboard after login
• Navigation: Sidebar/header navigation
• User Profile: User information display
• Logout Functionality: Secure session termination

🔄 Spoof Checker Feature

• Email Spoof Detection: Core functionality mentioned in routes
• Results Display: Show spoof check results
• History: Track previous spoof checks
• API Integration: Backend endpoints for spoof checking

🔄 Enhanced User Management

• User List Display: Show all users in table format
• User Editing: Update user information
• User Deletion: Remove users with confirmation
• Credit System: Add/manage user credits (UI exists but not functional)

🔄 Error Handling & UX

• Global Error Handler: Consistent error messaging
• Loading States: Better loading indicators
• Form Validation: Frontend validation with error messages
• Toast Notifications: Success/error notifications

🔄 Security Enhancements

• Protected Routes: Route guards based on authentication
• Role-Based UI: Show/hide features based on user role
• Token Refresh: Automatic token renewal
• Session Management: Proper logout and session cleanup

🔄 Testing & Documentation

• Unit Tests: Backend service tests
• Integration Tests: API endpoint tests
• Frontend Tests: Component testing
• API Documentation: Swagger/OpenAPI docs

Technical Requirements

Environment Setup

• Node.js: Version 16+ required
• MongoDB: Local or cloud instance
• Environment Variables: JWT_SECRET, DB_CONNECTION_STRING
• Port Configuration: Backend on 8001, Frontend on development server

Dependencies

• Backend: express, mongoose, jsonwebtoken, bcryptjs, cors, express-validator
• Frontend: react, react-router-dom, tailwindcss, lucide-react

Success Criteria

1. Complete Authentication Flow: Users can register, login, and access protected areas
2. Functional Spoof Checker: Core feature works and displays results
3. Admin User Management: Admins can manage users and roles effectively
4. Responsive Design: Works on desktop and mobile devices
5. Secure Implementation: Proper authentication and authorization
6. Error Handling: Graceful error handling throughout the application

Deployment Goals

• Frontend: Deploy to Vercel/Netlify
• Backend: Deploy to Railway/Render
• Database: MongoDB Atlas for production
• Environment: Separate dev/staging/production configs

This PRD serves as the foundation for completing the FirstList assignment project and demonstrating full-stack development capabilities.
