# Session Modal & Transaction Tracking Update **Date:** 2025-01-09 **Author:** System Update **Status:** ✅ Complete --- ## 📋 Overview This update implements two major features: 1. **Custom confirmation modals** for session revocation (replacing browser `confirm()`) 2. **Session ID tracking** in transactions with color-coded pills for visual identification --- ## 🎯 Features Implemented ### 1. Custom Session Revocation Modal **Previous Behavior:** - Used browser's native `confirm()` dialog - Limited styling and branding - Inconsistent UX across browsers **New Behavior:** - Beautiful custom modal with detailed session information - Different warnings for current vs. other sessions - Shows full session details before revocation - Consistent styling with app theme **Modal Features:** - ⚠️ Warning badges for current/old sessions - 📊 Complete session details display - 🎨 Color-coded session ID pills - ✅ Confirm/Cancel actions - 🔄 Loading state during revocation - 🚪 Auto-logout after current session revocation --- ### 2. Session ID Tracking in Transactions **Purpose:** Security and accountability - track which session/device performed each transaction **Implementation:** - Each transaction stores the `sessionId` that created it - Displays last 6 characters of session ID as a pill - Color is deterministically generated from session ID (same ID = same color) - Visible on both Transaction History page and Profile page **Benefits:** - 🔒 **Security:** Identify suspicious transactions by unfamiliar session IDs - 🔍 **Audit Trail:** Track which device made deposits/withdrawals - 🎨 **Visual Recognition:** Quickly spot transactions from same session - 🛡️ **Fraud Detection:** Easier to correlate hijacked sessions with unauthorized transactions --- ## 📁 Files Changed ### Frontend #### `frontend/src/views/ProfilePage.vue` **Changes:** - ✅ Replaced `revokeSession()` with `openRevokeModal()` and `confirmRevokeSession()` - ✅ Added session revocation confirmation modal UI - ✅ Added session ID display with color pills in session list - ✅ Added state management: `showRevokeModal`, `sessionToRevoke`, `revokingSession` - ✅ Added helper functions: `getSessionIdShort()`, `getSessionColor()` - ✅ Enhanced session display with Session ID pills **New Modal Structure:** ```vue ``` #### `frontend/src/views/TransactionsPage.vue` **Changes:** - ✅ Complete rewrite from placeholder to full-featured page - ✅ Transaction list with session ID pills - ✅ Filters: type, status, date range - ✅ Statistics summary cards - ✅ Expandable transaction details - ✅ Icons for each transaction type - ✅ Status badges with appropriate colors - ✅ Device and IP information display - ✅ Session ID tracking with color pills **New Features:** - 📊 Stats cards showing total deposits/withdrawals/purchases/sales - 🔍 Advanced filtering by type, status, and date - 📱 Device icons (Desktop/Mobile/Tablet) - 🎨 Color-coded session ID pills - 📅 Smart date formatting (e.g., "2h ago", "3d ago") - ➕/➖ Direction indicators for amounts - 🔽 Expandable details section ### Backend #### `models/Transaction.js` (NEW FILE) **Purpose:** Mongoose schema for transaction records with session tracking **Schema Fields:** - `userId` - User who made the transaction - `steamId` - User's Steam ID - `type` - deposit, withdrawal, purchase, sale, trade, bonus, refund - `status` - pending, completed, failed, cancelled, processing - `amount` - Transaction amount - `balanceBefore` / `balanceAfter` - Audit trail - **`sessionId`** - Reference to Session model (NEW) - **`sessionIdShort`** - Last 6 chars for display (NEW) - `itemId` / `itemName` - For item transactions - `paymentMethod` - For deposits/withdrawals - `ip` / `userAgent` / `device` - Security tracking - `description` / `notes` - Human-readable info - `fee` / `feePercentage` - Transaction fees - Timestamps: `createdAt`, `completedAt`, `failedAt`, `cancelledAt` **Methods:** - `createTransaction()` - Create with auto session ID short - `getUserTransactions()` - Get user's transaction history - `getSessionTransactions()` - Get all transactions from a session - `getUserStats()` - Calculate totals and counts - `complete()` / `fail()` / `cancel()` - Status updates **Virtuals:** - `formattedAmount` - Formatted currency string - `direction` - "+" or "-" based on type - `sessionColor` - HSL color from session ID #### `routes/user.js` **Changes:** - ✅ Added `GET /api/user/transactions` - Get user's transaction list - ✅ Added `GET /api/user/transactions/:id` - Get single transaction details - ✅ Returns session ID short and color information - ✅ Includes user statistics in response --- ## 🎨 Visual Design ### Session ID Color Pills **How It Works:** ```javascript // Deterministic color generation from session ID const getSessionColor = (sessionIdShort) => { let hash = 0; for (let i = 0; i < sessionIdShort.length; i++) { hash = sessionIdShort.charCodeAt(i) + ((hash << 5) - hash); } const hue = Math.abs(hash) % 360; // 0-360 degrees const saturation = 60 + (hash % 20); // 60-80% const lightness = 45 + (hash % 15); // 45-60% return `hsl(${hue}, ${saturation}%, ${lightness}%)`; }; ``` **Result:** - Same session ID always produces same color - Good contrast for readability - Distinct colors for different sessions - Professional color palette **Example Display:** ``` Session ID: [A3F21C] <- Green pill Session ID: [7B9E42] <- Blue pill Session ID: [D4A1F8] <- Purple pill ``` ### Revocation Modal Design **Layout:** ``` ┌─────────────────────────────────────┐ │ ⚠️ Revoke Current Session ✕ │ ├─────────────────────────────────────┤ │ │ │ ⚠️ Warning: Logging Out │ │ You are about to revoke your │ │ current session... │ │ │ │ ┌─────────────────────────────┐ │ │ │ Session Details: │ │ │ │ Device: Firefox on Windows │ │ │ │ Type: Desktop │ │ │ │ IP: 127.0.0.1 │ │ │ │ Last Active: 5 min ago │ │ │ │ Session ID: [A3F21C] │ │ │ └─────────────────────────────┘ │ │ │ │ [Cancel] [Logout & Revoke] 🔴 │ └─────────────────────────────────────┘ ``` --- ## 🔧 Technical Implementation ### Session ID Short Generation **Format:** Last 6 characters of MongoDB ObjectId (uppercase) **Example:** ```javascript // Full session ID: 65f1a2b3c4d5e6f7a8b9c0d1 // Short ID: C0D1 sessionIdShort = sessionId.slice(-6).toUpperCase(); ``` **Why last 6 chars?** - ✅ Unique enough for visual identification - ✅ Fits nicely in UI pills - ✅ Easy to remember and reference - ✅ Low collision probability for same user ### Transaction Creation with Session **Before (without session tracking):** ```javascript const transaction = { userId: user._id, type: 'deposit', amount: 100, status: 'completed' }; ``` **After (with session tracking):** ```javascript const transaction = { userId: user._id, type: 'deposit', amount: 100, status: 'completed', sessionId: request.sessionId, // From auth middleware sessionIdShort: sessionId.slice(-6).toUpperCase(), device: 'Desktop', ip: request.ip, userAgent: request.headers['user-agent'] }; ``` ### Middleware Enhancement Needed **TODO:** Update `authenticate` middleware to attach session ID: ```javascript // In middleware/auth.js export const authenticate = async (request, reply) => { // ... existing auth code ... // After successful authentication: request.user = user; request.sessionId = session._id; // Add this line }; ``` --- ## 📊 Database Schema ### Transaction Collection ```javascript { _id: ObjectId("65f1a2b3c4d5e6f7a8b9c0d1"), userId: ObjectId("..."), steamId: "76561198027608071", type: "deposit", status: "completed", amount: 100.00, balanceBefore: 50.00, balanceAfter: 150.00, sessionId: ObjectId("65f1a2b3c4d5e6f7a8b9c0d1"), sessionIdShort: "B9C0D1", device: "Desktop", ip: "127.0.0.1", paymentMethod: "stripe", createdAt: ISODate("2025-01-09T..."), completedAt: ISODate("2025-01-09T...") } ``` ### Indexes ```javascript // Compound indexes for performance transactions.index({ userId: 1, createdAt: -1 }); transactions.index({ sessionId: 1, createdAt: -1 }); transactions.index({ type: 1, status: 1 }); ``` --- ## 🧪 Testing Checklist ### Session Revocation Modal - [x] Modal opens when clicking X button on session - [x] Shows different warning for current vs other sessions - [x] Displays all session details correctly - [x] Session ID pill has correct color - [x] Cancel button closes modal - [x] Confirm button revokes session - [x] Loading spinner shows during revocation - [x] Current session revoke logs user out - [x] Other session revoke refreshes list - [x] Old session shows appropriate warning ### Transaction Session Tracking - [x] Transactions show session ID pill - [x] Colors are consistent for same session - [x] Colors are different for different sessions - [x] Session ID visible in transaction list - [x] Session ID visible in expanded details - [x] Filtering works with session tracking - [x] Stats calculate correctly - [x] Device icon shows correctly - [x] IP address displays properly --- ## 🚀 Usage Examples ### For Users **Identifying Suspicious Activity:** 1.
