# 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
|
||

#### `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 });
|
||
```

## 🚀 Usage Examples
|
||
|
||
### For Users
|
||
|
||
**Identifying Suspicious Activity:**
|
||
1. Go to **Transaction History**
|
||
2. Look at session ID pills
|
||
3. If you see an unfamiliar color, click to expand
|
||
4. Check device, IP, and timestamp
|
||
5. If unrecognized, go to **Profile → Active Sessions**
|
||
6. Find session with matching color pill
|
||
7. Click X to revoke it
|
||
|
||
**Tracking Your Own Transactions:**
|
||
- Each device will have a consistent color
|
||
- Easy to see which device made which purchase
|
||
- Helpful for personal accounting
|
||
|
||
### For Developers
|
||
|
||
**Creating Transactions:**
|
||
```javascript
|
||
const transaction = await Transaction.createTransaction({
|
||
userId: user._id,
|
||
steamId: user.steamId,
|
||
type: 'purchase',
|
||
amount: 49.99,
|
||
balanceBefore: user.balance,
|
||
balanceAfter: user.balance - 49.99,
|
||
sessionId: request.sessionId, // From middleware
|
||
itemId: item._id,
|
||
itemName: item.name,
|
||
device: 'Desktop',
|
||
ip: request.ip
|
||
});
|
||
```
|
||
|
||
**Querying Transactions:**
|
||
```javascript
|
||
// Get all transactions from a session
|
||
const transactions = await Transaction.getSessionTransactions(sessionId);
|
||
|
||
// Get user's transaction history
|
||
const transactions = await Transaction.getUserTransactions(userId, {
|
||
limit: 50,
|
||
type: 'deposit',
|
||
status: 'completed'
|
||
});
|
||
```
|

||
- ❌ No accountability for transactions
|
||
|
||
### After Session Tracking
|
||
- ✅ Every transaction linked to session
|
||
- ✅ Quick visual identification of device
|
||
- ✅ Easy to correlate suspicious transactions
|
||
- ✅ Full audit trail for investigations
|
||
- ✅ Users can self-identify unauthorized activity
|
||
- ✅ Color coding makes patterns obvious

|
||
|
||
## 🐛 Known Issues / Limitations
|
||
|
||
### Current Limitations
|
||
1. **Backwards Compatibility:** Old transactions won't have session IDs
|
||
- **Solution:** Show "SYSTEM" for null sessionId
|
||
|
||
2. **Session Deletion:** If session is deleted, transaction still references it
|
||
- **Solution:** Keep sessionIdShort even if session deleted
|
||
|
||
3. **Color Collisions:** Theoretical possibility of same color for different sessions
|
||
- **Probability:** Very low (~1/360 for same hue)
|
||
- **Impact:** Low - users can still see full session ID
|
||
|
||
4. **Manual Transactions:** Admin-created transactions may not have sessions
|
||
- **Solution:** Use "ADMIN" or "SYSTEM" as sessionIdShort
