+- Backend API: http://localhost:5000
+
+### Production Build
+
+```bash
+# Build the client
+npm run build
+
+# Start the server
+npm start
+```
+

+# OneRoom - Feature Documentation
+
+## Overview
+OneRoom is a comprehensive roommate management application that simplifies shared living by automating expense splitting and task assignment.
+
+## Core Features
+
+### 1. User Authentication & Authorization
+- **Secure Registration & Login**: JWT-based authentication with bcrypt password hashing (12 salt rounds)
+- **Protected Routes**: All API endpoints require authentication
+- **Rate Limiting**:
+ - Authentication endpoints: 5 requests per 15 minutes
+ - Create operations: 30 requests per 15 minutes
+ - General API: 100 requests per 15 minutes
+
+### 2. Room Management
+- **Create Rooms**: Users can create multiple living spaces
+- **Unique Invite Codes**: Each room gets a unique 8-character code for easy sharing
+- **Role-Based Access**:
+ - Admin: Can modify room settings and remove members
+ - Member: Can participate and view room content
+- **Multi-Room Support**: Users can join and manage multiple rooms simultaneously
+
+### 3. Expense Management
+
+#### Expense Tracking
+- Add expenses with description, amount, and category
+- Categories: Groceries, Utilities, Rent, Entertainment, Other
+- Automatic timestamp for all expenses
+- View expense history by room
+
+#### Smart Splitting
+- **Equal Split (Default)**: Automatically divides expenses equally among all roommates
+- **Custom Percentage Split**: Set custom percentages for different split scenarios
+- Precise calculation with 2 decimal places
+
+#### Balance Calculation
+- Real-time calculation of who owes whom
+- Smart settlement algorithm minimizes the number of transactions needed
+- Clear settlement recommendations (e.g., "Alice owes Bob $25.50")
+- Mark individual splits as settled when paid
+
+#### Settlement Features
+- Track settlement status per person per expense
+- Calculate net balances across all expenses
+- Optimized settlement plan to minimize transactions
+
+### 4. Task Management
+
+#### Task Creation & Organization
+- Create tasks with title, description, and category
+- Categories: Cleaning, Cooking, Shopping, Maintenance, Other
+- Set priority levels: Low, Medium, High
+- Add due dates for time-sensitive tasks
+- Track status: Pending, In Progress, Completed
+
+#### Automatic Task Assignment
+- **Fair Distribution Algorithm**:
+ - Tracks assignment history per category
+ - Assigns tasks to the member with least recent assignments
+ - Tie-breaker: Assigns to member who was assigned longest ago
+ - Ensures fair rotation across all roommates
+
+#### Recurring Tasks
+- Set tasks to recur: Daily, Weekly, or Monthly
+- **Auto-Rotation**: When completed, automatically creates next occurrence and assigns to next person
+- Smart date calculation:
+ - Daily: Adds 1 day
+ - Weekly: Adds 7 days
+ - Monthly: Handles month-end edge cases (e.g., Jan 31 → Feb 28)
+
+#### Personal Task Dashboard
+- View all assigned tasks across all rooms
+- Filter by status (All, Pending, In Progress, Completed)
+- Quick actions: Start task, Mark as complete
+- See task details including room, priority, and due date
+
+### 5. User Interface
+
+#### Responsive Design
+- Mobile-first responsive layout

+## Technical Architecture
+
+### Backend Stack

+- **Database**: MongoDB with Mongoose ODM
+- **Authentication**: JWT + bcryptjs
+- **Security**: express-rate-limit, CORS
+- **Utilities**: uuid (for invite codes)
+
+### Frontend Stack
+- **Library**: React 18
+- **Routing**: React Router DOM v6
+- **HTTP Client**: Axios
+- **Styling**: Custom CSS3 with modern features
+- **Build Tool**: Create React App
+
+### API Structure
+- RESTful API design
+- JSON request/response format
+- Consistent error handling
+- Standard HTTP status codes
+- Bearer token authentication
+
+## Algorithms
+
+### Expense Settlement Algorithm
+1. Initialize balance for each member to 0
+2. For each expense:
+ - Credit the payer with the full amount
+ - Debit each person in the split for their share
+3. Separate members into debtors (negative balance) and creditors (positive balance)
+4. Create minimum transactions:
+ - Match smallest debt with smallest credit
+ - Create settlement transaction
+ - Continue until all balances are zero
+
+### Task Assignment Algorithm
+1. Get recent task history for the category
+2. Count assignments per member
+3. Track last assignment date per member
+4. Find members with minimum assignment count
+5. If tie, select member assigned longest ago (or never assigned)
+6. Return selected member for assignment
+
+### Recurring Task Rotation
+1. When task is marked complete:
+ - Create new task instance with same properties
+ - Calculate next due date based on frequency
+ - Use assignment algorithm to get next assignee
+ - Save new task and mark original as complete
+
+## Future Enhancement Possibilities
+
+### Potential Features
+- Push notifications for new expenses and tasks
+- Mobile app (React Native)
+- Expense categories analytics and charts
+- Task completion statistics
+- Shopping lists with auto-assignment
+- Calendar integration for tasks
+- Bill reminders and recurring expenses
+- Photo attachments for expenses
+- Task comments and discussions
+- Room announcements board
+- Integration with payment apps (Venmo, PayPal)
+- Export data (CSV, PDF reports)
+- Dark mode theme
+- Multiple language support
+
+### Scalability Considerations
+- Database indexing for performance
+- Caching layer (Redis)
+- Background job processing for recurring tasks
+- WebSocket for real-time updates
+- CDN for static assets
+- Load balancing for high traffic
+- Database replication and backups
+
+## Development Guidelines
+
+### Running Locally
+1. Install MongoDB and ensure it's running
+2. Copy `.env.example` to `.env` and configure
+3. Run `npm install` and `cd client && npm install`
+4. Start with `npm run dev-all` for full stack development
+
+### Code Quality
+- All routes include rate limiting
+- Authentication required for protected endpoints
+- Input validation on all user data
+- Consistent error handling patterns
+- Comments for complex algorithms
+- Modular code organization
+
+### Security Checklist
+- ✅ Password hashing (bcrypt with 12 rounds)
+- ✅ JWT token authentication
+- ✅ Rate limiting on all endpoints
+- ✅ Environment variable validation
+- ✅ Protected routes
+- ✅ CORS configuration
+- ✅ No sensitive data in error messages
+- ✅ Input validation
+- ✅ No hardcoded secrets in production

+# Future Improvements & Enhancement Ideas
+
+This document tracks potential improvements and enhancements for OneRoom.
+
+## Code Quality Improvements
+
+### High Priority
+- [ ] Replace browser `alert()` calls with toast notifications or inline error messages
+ - Affects: Dashboard.js, MyTasks.js, RoomDetails.js
+ - Benefit: Better user experience with non-blocking notifications
+
+### Medium Priority
+- [ ] Fix task priority sorting to use numeric values
+ - Current: Alphabetic sort on string values
+ - Better: Map priority to numbers (high=3, medium=2, low=1) for correct sorting
+
+- [ ] Use safer hasOwnProperty checks
+ - Change: `assignmentCounts.hasOwnProperty(userId)`
+ - To: `Object.prototype.hasOwnProperty.call(assignmentCounts, userId)` or `userId in assignmentCounts`
+
+### Low Priority
+- [ ] Preserve custom split proportions when updating expense amounts
+ - Current behavior: Reverts to equal split when amount is changed
