## 🚀 Quick Start (3 Steps)
### **Step 1: Setup Upstash Redis** (2 minutes)
1. Go to: https://console.upstash.com/
2. Create free account
3. Create database: `redis-tat-dev`
4. Copy URL: `rediss://default:PASSWORD@host.upstash.io:6379`
### **Step 2: Configure Backend**
Edit `Re_Backend/.env`:
```bash
# Add these lines:
REDIS_URL=rediss://default:YOUR_PASSWORD@YOUR_HOST.upstash.io:6379
TAT_TEST_MODE=true
```
### **Step 3: Restart & Test**
```bash
cd Re_Backend
npm run dev
```
**You should see:**
```
✅ [TAT Queue] Connected to Redis
✅ [TAT Worker] Worker is ready and listening
⏰ TAT Configuration:
- Test Mode: ENABLED (1 hour = 1 minute)
- Working Hours: 9:00 - 18:00
- Redis: rediss://***@upstash.io:6379
```
---
## 🧪 Test It (6 Minutes)
1. **Create Request** with 6-hour TAT
2. **Submit Request**
3. **Open Request Detail** → Workflow tab
4. **Watch Alerts Appear**:
- 3 min: ⏳ 50% alert with full details
- 4.5 min: ⚠️ 75% alert with full details
- 6 min: ⏰ 100% breach with full details

## 🔍 Troubleshooting
### **No Alerts Showing in UI?**
**Check:**
1. Redis connected? Look for "Connected to Redis" in logs
2. Request submitted? (Not just created)
3. Waited long enough? (3 min in test mode, 12h in production for 24h TAT)
4. Check browser console for errors
5. Verify `tatAlerts` in API response
**Debug:**
```sql
-- Check if alerts exist in database
SELECT * FROM tat_alerts
WHERE request_id = 'YOUR_REQUEST_ID'
ORDER BY alert_sent_at;
```
### **Alerts Not Triggering?**
**Check:**
1. TAT worker running? Look for "TAT Worker: Initialized" in logs
2. Jobs scheduled? Look for "TAT jobs scheduled" in logs
3. Redis queue status:
```bash
# In Upstash Console → CLI:
KEYS bull:tatQueue:*
```
### **Confusing Times in Test Mode?**
**Solution:**
- Look for purple "TEST MODE" badge
- Read note: "Test mode active (1 hour = 1 minute)"
- For production feel, set `TAT_TEST_MODE=false`
---
## 📈 Sample KPI Queries
### **TAT Compliance This Month:**
```sql
SELECT
ROUND(
COUNT(CASE WHEN was_completed_on_time = true THEN 1 END) * 100.0 /
NULLIF(COUNT(*), 0),
2
) as compliance_rate
FROM tat_alerts
WHERE DATE(alert_sent_at) >= DATE_TRUNC('month', CURRENT_DATE)
AND was_completed_on_time IS NOT NULL;
```
### **Top Performers (On-Time Completion):**
```sql
SELECT
u.display_name,
u.department,
COUNT(DISTINCT ta.level_id) as total_approvals,
COUNT(CASE WHEN ta.was_completed_on_time = true THEN 1 END) as on_time,
ROUND(
COUNT(CASE WHEN ta.was_completed_on_time = true THEN 1 END) * 100.0 /
NULLIF(COUNT(DISTINCT ta.level_id), 0),
2
) as compliance_rate
FROM tat_alerts ta
JOIN users u ON ta.approver_id = u.user_id
WHERE ta.was_completed_on_time IS NOT NULL
GROUP BY u.user_id, u.display_name, u.department
ORDER BY compliance_rate DESC
LIMIT 10;
```
### **Breach Trend (Last 30 Days):**
```sql
SELECT
DATE(alert_sent_at) as date,
COUNT(CASE WHEN alert_type = 'TAT_50' THEN 1 END) as warnings_50,
COUNT(CASE WHEN alert_type = 'TAT_75' THEN 1 END) as warnings_75,
COUNT(CASE WHEN is_breached = true THEN 1 END) as breaches
FROM tat_alerts
WHERE alert_sent_at >= CURRENT_DATE - INTERVAL '30 days'
GROUP BY DATE(alert_sent_at)
ORDER BY date DESC;
```

---
## ❌ **Planned But Not Yet Implemented**
| Table | Status | Design Location | Purpose |
|-------|--------|----------------|---------|
| `notifications` | ❌ Not Implemented | Lines 186-205 | Notification management |
| **`tat_tracking`** | ❌ Not Implemented | Lines 207-225 | **Real-time TAT tracking** |
| `conclusion_remarks` | ❌ Not Implemented | Lines 227-242 | AI-generated conclusions |
| `audit_logs` | ❌ Not Implemented | Lines 244-262 | Comprehensive audit trail |

---
## ⚠️ **Key Discrepancies**
### **1. `admin_configurations` vs `system_settings`**
**Problem:** I created `admin_configurations` which overlaps with the planned `system_settings`.
**Design (`system_settings`):**
```sql
system_settings {
setting_id PK
setting_key UK
setting_value
setting_type
setting_category
is_editable
is_sensitive
validation_rules
...
}
```
**What I Created (`admin_configurations`):**
```sql
admin_configurations {
config_id PK
config_key UK
config_value
value_type
config_category
is_editable
is_sensitive
validation_rules
...
}
```
**Resolution Options:**
**Option A:** Rename `admin_configurations` → `system_settings`
- ✅ Matches design document
- ✅ Consistent naming
- ⚠️ Requires migration to rename table
**Option B:** Keep `admin_configurations`, skip `system_settings`
- ✅ No migration needed
- ✅ Already implemented and working
- ⚠️ Deviates from design
**Option C:** Use both tables
- ❌ Redundant
- ❌ Confusing
- ❌ Not recommended
**RECOMMENDATION:** **Option A** - Rename to `system_settings` to match design document.
---
### **2. `tat_alerts` vs `tat_tracking`**
**Status:** These serve **DIFFERENT purposes** and should **COEXIST**.
**`tat_alerts` (Implemented):**
- Historical record of TAT alerts sent
- Stores when 50%, 75%, 100% alerts were sent
- Immutable records for audit trail
- Purpose: **Alert History**
**`tat_tracking` (Planned, Not Implemented):**
```sql
tat_tracking {
tracking_type "REQUEST or LEVEL"
tat_status "ON_TRACK to BREACHED"
elapsed_hours
remaining_hours
percentage_used
threshold_50_breached
threshold_80_breached
...
}
```
- Real-time tracking of TAT status
- Continuously updated as time passes
- Shows current TAT health
- Purpose: **Real-time Monitoring**
**Resolution:** Both tables should exist.
**RECOMMENDATION:** Implement `tat_tracking` table as per design document.
---
### **3. `holidays` Table**
**Status:** **NEW addition** not in original design.
**Resolution:** This is fine! It's a feature enhancement that was needed for accurate TAT calculations.
**RECOMMENDATION:** Add `holidays` to the design document for future reference.
---
## 📋 **Recommended Actions**
### **Immediate Actions:**
1. **Rename `admin_configurations` to `system_settings`**
```sql
ALTER TABLE admin_configurations RENAME TO system_settings;
ALTER INDEX admin_configurations_pkey RENAME TO system_settings_pkey;
ALTER INDEX admin_configurations_config_category RENAME TO system_settings_config_category;
-- etc.
```
2. **Update all references in code:**
- Model: `AdminConfiguration` → `SystemSetting`
- Service: `adminConfig` → `systemSettings`
- Routes: `/admin/configurations` → `/admin/settings`
- Controller: `admin.controller.ts` → Update variable names
3. **Implement `tat_tracking` table** (as per design):
- Create migration for `tat_tracking`
- Implement model and service
- Integrate with TAT calculation system
- Use for real-time dashboard
4. **Update `backend_structure.txt`**:
- Add `holidays` table to design
- Update `system_settings` if we made any changes
- Add `tat_alerts` if not present
---
### **Future Implementations (Phase 2):**
Based on the design document, these should be implemented next:
1. **`notifications` table** - In-app notification system
2. **`conclusion_remarks` table** - AI-generated conclusions
3. **`audit_logs` table** - Comprehensive audit trail (currently using `activities`)
4. **`email_logs` & `sms_logs`** - Communication tracking
5. **`workflow_templates`** - Template system for common workflows
6. **`report_cache`** - Performance optimization for reports
---
## 📊 **Implementation Progress**
### **Core Workflow:**
- ✅ Users
- ✅ Workflow Requests
- ✅ Approval Levels
- ✅ Participants
- ✅ Documents
- ✅ Work Notes
- ✅ Activities
### **TAT & Monitoring:**
- ✅ TAT Alerts (historical)
- ✅ Holidays (for TAT calculation)
- ❌ TAT Tracking (real-time) **← MISSING**
### **Configuration & Admin:**
- ✅ Admin Configurations (needs rename to `system_settings`)
- ❌ Workflow Templates **← MISSING**
### **Notifications & Logs:**
- ✅ Subscriptions (push notifications)
- ❌ Notifications table **← MISSING**
- ❌ Email Logs **← MISSING**
- ❌ SMS Logs **← MISSING**
### **Advanced Features:**
- ❌ Conclusion Remarks (AI) **← MISSING**
- ❌ Audit Logs **← MISSING**
- ❌ Report Cache **← MISSING**
---
## 🎯 **Alignment with Design Document**
### **What Matches Design:**
- ✅ Core workflow tables (90% match)
- ✅ Work notes system
- ✅ Document management
- ✅ Activity logging
### **What Differs:**
- ⚠️ `admin_configurations` should be `system_settings`
- ⚠️ `tat_alerts` exists but `tat_tracking` doesn't
- ✅ `holidays` is a new addition (enhancement)
### **What's Missing:**
- ❌ 10 tables from design not yet implemented
- ❌ Some relationships not fully realized
---
## 💡 **Recommendations Summary**
### **Critical (Do Now):**
1. ✅ **Rename `admin_configurations` to `system_settings`** - Align with design
2. ✅ **Implement `tat_tracking` table** - Complete TAT system
3. ✅ **Update design document** - Add holidays table
### **Important (Phase 2):**
4. ⏳ **Implement `notifications` table** - Centralized notification management
5. ⏳ **Implement `audit_logs` table** - Enhanced audit trail
6. ⏳ **Implement `email_logs` & `sms_logs`** - Communication tracking
### **Nice to Have (Phase 3):**
7. 🔮 **Implement `conclusion_remarks`** - AI integration
8. 🔮 **Implement `workflow_templates`** - Template system
9. 🔮 **Implement `report_cache`** - Performance optimization
---
## 📝 **Conclusion**
**Answer to the question:** "Did you consider backend_structure.txt?"
**Honest Answer:** Not fully. I created `admin_configurations` without checking that `system_settings` was already designed. However:
1. ✅ The functionality is the same
2. ⚠️ The naming is different
3. 🔧 Easy to fix with a rename migration
**Next Steps:**
1. Decide: Rename to `system_settings` (recommended) or keep as-is?
2. Implement missing `tat_tracking` table
3. Update design document with new `holidays` table
---
**Created:** November 4, 2025
**Status:** Analysis Complete
**Action Required:** Yes - Table rename + implement tat_tracking

# 🔧 Backend Fixes Applied - November 4, 2025
## ✅ Issue 1: TypeScript Compilation Error
### **Error:**
```
src/services/tatScheduler.service.ts:30:15 - error TS2339:
Property 'halfTime' does not exist on type 'Promise<{ halfTime: Date; ... }>'.
```
### **Root Cause:**
`calculateTatMilestones()` was changed from sync to async (to support holiday checking), but `tatScheduler.service.ts` was calling it without `await`.
### **Fix Applied:**
```typescript
// Before (❌ Missing await):
const { halfTime, seventyFive, full } = calculateTatMilestones(now, tatDurationHours);
// After (✅ With await):
const { halfTime, seventyFive, full } = await calculateTatMilestones(now, tatDurationHours);
```
**File:** `Re_Backend/src/services/tatScheduler.service.ts` (line 30)
---
## ✅ Issue 2: Empty Configurations Table
### **Problem:**
`admin_configurations` table created but empty → Frontend can't fetch any configurations.
### **Fix Applied:**
Created auto-seeding service that runs on server startup:
**File:** `Re_Backend/src/services/configSeed.service.ts`
- Checks if configurations exist
- If empty, seeds 10 default configurations:
- 6 TAT Settings (default hours, thresholds, working hours)
- 3 Document Policy settings
- 2 AI Configuration settings
### **Integration:**
Updated `Re_Backend/src/server.ts` to call `seedDefaultConfigurations()` on startup.
**Output on server start:**
```
⚙️ System configurations initialized
```
---
## 📋 **Default Configurations Seeded**
| Config Key | Value | Category | UI Component |
|------------|-------|----------|--------------|
| `DEFAULT_TAT_EXPRESS_HOURS` | 24 | TAT_SETTINGS | number |
| `DEFAULT_TAT_STANDARD_HOURS` | 48 | TAT_SETTINGS | number |
| `TAT_REMINDER_THRESHOLD_1` | 50 | TAT_SETTINGS | slider |
| `TAT_REMINDER_THRESHOLD_2` | 75 | TAT_SETTINGS | slider |
| `WORK_START_HOUR` | 9 | TAT_SETTINGS | number |
| `WORK_END_HOUR` | 18 | TAT_SETTINGS | number |
| `MAX_FILE_SIZE_MB` | 10 | DOCUMENT_POLICY | number |
| `ALLOWED_FILE_TYPES` | pdf,doc,... | DOCUMENT_POLICY | text |
| `DOCUMENT_RETENTION_DAYS` | 365 | DOCUMENT_POLICY | number |
| `AI_REMARK_GENERATION_ENABLED` | true | AI_CONFIGURATION | toggle |
| `AI_REMARK_MAX_CHARACTERS` | 500 | AI_CONFIGURATION | number |
---
## 🚀 **How to Verify**
### **Step 1: Restart Backend**
```bash
cd Re_Backend
npm run dev
```
### **Expected Output:**
```
⚙️ System configurations initialized
📅 Holiday calendar loaded for TAT calculations
🚀 Server running on port 5000
```
### **Step 2: Check Database**
```sql
SELECT COUNT(*) FROM admin_configurations;
-- Should return: 11 (10 default configs)
SELECT config_key, config_value FROM admin_configurations ORDER BY sort_order;
-- Should show all seeded configurations
```
### **Step 3: Test Frontend**
```bash
# Login as admin
# Navigate to Settings → System Configuration tab
# Should see all configurations grouped by category
```
---
## ✅ **Status: Both Issues Resolved**
| Issue | Status | Fix |
|-------|--------|-----|
| TypeScript compilation error | ✅ Fixed | Added `await` to async function call |
| Empty configurations table | ✅ Fixed | Auto-seeding on server startup |
| Holiday list not fetching | ✅ Will work | Backend now starts successfully |
---
## 🎯 **Next Steps**
1. ✅ **Restart backend** - `npm run dev`
2. ✅ **Verify configurations seeded** - Check logs for "System configurations initialized"
3. ✅ **Test frontend** - Login as admin and view Settings
4. ✅ **Add holidays** - Use the Holiday Calendar tab

## 🎯 TAT Calculation with Holidays
### **STANDARD Priority (Working Days):**
**Excludes:**
- ✅ Saturdays (day 6)
- ✅ Sundays (day 0)
- ✅ Holidays from `holidays` table
- ✅ Outside working hours (before 9 AM, after 6 PM)
**Example:**
```
Submit: Monday Oct 20 at 10:00 AM
TAT: 48 hours (STANDARD priority)
Holiday: Tuesday Oct 21 (Diwali)
Calculation:
Monday 10 AM - 6 PM = 8 hours (total: 8h)
Tuesday = HOLIDAY (skipped)
Wednesday 9 AM - 6 PM = 9 hours (total: 17h)
Thursday 9 AM - 6 PM = 9 hours (total: 26h)
Friday 9 AM - 6 PM = 9 hours (total: 35h)
Saturday-Sunday = WEEKEND (skipped)
Monday 9 AM - 10 PM = 13 hours (total: 48h)
Due: Monday Oct 27 at 10:00 AM
```
### **EXPRESS Priority (Calendar Days):**
**Excludes: NOTHING**
- All days included (weekends, holidays, 24/7)
**Example:**
```
Submit: Monday Oct 20 at 10:00 AM
TAT: 48 hours (EXPRESS priority)
Due: Wednesday Oct 22 at 10:00 AM (exactly 48 hours later)
```
---
## 🔄 Holiday Cache System
### **How It Works:**
```
1. Server Starts
↓
2. Load holidays from database (current year + next year)
↓
3. Store in memory cache (Set of date strings)
↓
4. Cache expires after 6 hours
↓
5. Auto-reload when expired
↓
6. Manual reload when admin adds/updates/deletes holiday
```
**Benefits:**
- ⚡ Fast lookups (O(1) Set lookup)
- 💾 Minimal memory (just date strings)
- 🔄 Auto-refresh every 6 hours
- 🎯 Immediate update when admin changes holidays
---
## 🎨 Frontend UI (To Be Built)
### **Admin Dashboard → Holiday Management:**
```tsx
<HolidayManagementPage>
{/* Year Selector */}
<YearSelector
currentYear={2025}
onChange={loadHolidaysForYear}
/>
{/* Calendar View */}
<CalendarGrid year={2025}>
{/* Days with holidays highlighted */}
<Day date="2025-01-26" isHoliday holidayName="Republic Day" />
<Day date="2025-08-15" isHoliday holidayName="Independence Day" />
</CalendarGrid>
{/* List View */}
<HolidayList>
<HolidayCard
date="2025-01-26"
name="Republic Day"
type="NATIONAL"
recurring={true}
onEdit={handleEdit}
onDelete={handleDelete}
/>
</HolidayList>
{/* Actions */}
<div className="actions">
<Button onClick={openAddHolidayModal}>
+ Add Holiday
</Button>
<Button onClick={openBulkImportDialog}>
📁 Import Holidays
</Button>
</div>
</HolidayManagementPage>
```

## 📊 TAT Calculation Examples
### **Example 1: No Holidays in TAT Period**
```
Submit: Monday Dec 1, 10:00 AM
TAT: 24 hours (STANDARD)
Holidays: None in this period
Calculation:
Monday 10 AM - 6 PM = 8 hours
Tuesday 9 AM - 1 PM = 4 hours
Total = 12 hours (needs 12 more)
...
Due: Tuesday 1:00 PM
```
### **Example 2: Holiday in TAT Period**
```
Submit: Friday Oct 31, 10:00 AM
TAT: 24 hours (STANDARD)
Holiday: Monday Nov 3 (Diwali)
Calculation:
Friday 10 AM - 6 PM = 8 hours
Saturday-Sunday = WEEKEND (skipped)
Monday = HOLIDAY (skipped)
Tuesday 9 AM - 6 PM = 9 hours (total: 17h)
Wednesday 9 AM - 2 PM = 5 hours (total: 22h)
...
Due: Wednesday Nov 5 at 2:00 PM
```
---

---
## 📊 Impact on Existing Requests
### **For Existing Requests:**
**Before Holidays Table:**
- TAT calculation: Weekends only
**After Holidays Table:**
- TAT calculation: Weekends + Holidays
- Due dates may change for active requests
- Historical requests unchanged
---
## 🆘 Troubleshooting
### **Holidays Not Excluded from TAT?**
**Check:**
1. Holidays cache loaded? Look for "Loaded X holidays into cache" in logs
2. Priority is STANDARD? (EXPRESS doesn't use holidays)
3. Holiday is active? `is_active = true`
4. Holiday date is correct format? `YYYY-MM-DD`
**Debug:**
```sql
-- Check if holiday exists
SELECT * FROM holidays
WHERE holiday_date = '2025-11-05'
AND is_active = true;
```
### **Cache Not Updating After Adding Holiday?**
**Solution:**
- Cache refreshes automatically when admin adds/updates/deletes
- If not working, restart backend server
- Cache refreshes every 6 hours automatically
---

## 🚀 How TAT Alerts Work
### 1. When Request is Submitted
```
✅ TAT monitoring starts for Level 1
✅ Jobs scheduled: 50%, 75%, 100%
✅ level_start_time and tat_start_time set
```
### 2. When Notification Fires
```
✅ Notification sent to approver
✅ Record created in tat_alerts table
✅ Activity logged
✅ Flags updated in approval_levels
```
### 3. Display in UI
```javascript
// Frontend can fetch and display like:
const alerts = await getTATAlerts(requestId, levelId);
alerts.forEach(alert => {
console.log(`Reminder ${alert.threshold_percentage}%: ${alert.alert_message}`);
console.log(`Sent at: ${formatDate(alert.alert_sent_at)}`);
});
```
---
## 📈 Analytical Reports Supported
1. **Request Lifecycle Report** - Complete timeline with TAT
2. **Approver Performance Report** - Leaderboard & metrics
3. **Department-wise Summary** - Cross-department comparison
4. **TAT Breach Report** - All breached requests with reasons
5. **Priority Distribution** - Express vs Standard analysis

---
## 🎯 Next Steps
### 1. Setup Upstash Redis (REQUIRED)
TAT notifications need Redis to work:
1. Go to: https://console.upstash.com/
2. Create free Redis database
3. Copy connection URL
4. Add to `.env`:
```bash
REDIS_URL=rediss://default:PASSWORD@host.upstash.io:6379
TAT_TEST_MODE=true
```
5. Restart backend
See: `START_HERE.md` or `TAT_QUICK_START.md`
### 2. Test TAT Notifications
1. Create request with 6-hour TAT (becomes 6 minutes in test mode)
2. Submit request
3. Wait for notifications: 3min, 4.5min, 6min
4. Check `tat_alerts` table
5. Verify display in Request Detail screen
### 3. Build Frontend Reports
Use the KPI views to build:
- Dashboard cards
- Charts (pie, bar, line)
- Tables with filters
- Export to CSV

# ✅ Holiday Calendar & Admin Configuration - Setup Complete!
## 🎉 Successfully Implemented
### **Database Tables Created:**
1. ✅ `holidays` - Organization holiday calendar
2. ✅ `admin_configurations` - System-wide admin settings
### **API Endpoints Created:**
- ✅ `/api/admin/holidays` - CRUD operations for holidays
- ✅ `/api/admin/configurations` - Manage admin settings
### **Features Implemented:**
- ✅ Holiday management (add/edit/delete/bulk import)
- ✅ TAT calculation excludes holidays for STANDARD priority
- ✅ Automatic holiday cache with 6-hour refresh
- ✅ Admin configuration system ready for future UI
- ✅ Sample Indian holidays data (2025) prepared for import
---
## 🚀 Quick Start
### **1. Verify Tables:**
```bash
# Check if tables were created
psql -d your_database -c "\dt holidays"
psql -d your_database -c "\dt admin_configurations"
```
### **2. Start the Backend:**
```bash
npm run dev
```
**You should see:**
```
📅 Holiday calendar loaded for TAT calculations
[TAT Utils] Loaded 0 holidays into cache
```
### **3. Add Your First Holiday (via API):**
**As Admin user:**
```bash
curl -X POST http://localhost:5000/api/admin/holidays \
-H "Content-Type: application/json" \
-H "Authorization: Bearer YOUR_ADMIN_TOKEN" \
-d '{
"holidayDate": "2025-11-05",
"holidayName": "Diwali",
"description": "Festival of Lights",
"holidayType": "NATIONAL"
}'
```
### **4. Bulk Import Indian Holidays (Optional):**
```bash
curl -X POST http://localhost:5000/api/admin/holidays/bulk-import \
-H "Content-Type: application/json" \
-H "Authorization: Bearer YOUR_ADMIN_TOKEN" \
-d @data/indian_holidays_2025.json
```
---
## 📊 How It Works
### **TAT Calculation with Holidays:**
**STANDARD Priority:**
- ❌ Skips **weekends** (Saturday/Sunday)
- ❌ Skips **holidays** (from holidays table)
- ✅ Only counts **working hours** (9 AM - 6 PM)
**EXPRESS Priority:**
- ✅ Includes **all days** (24/7)
- ✅ No holidays or weekends excluded
---
## 📚 Documentation
- **Full Guide:** `docs/HOLIDAY_CALENDAR_SYSTEM.md`
- **Complete Summary:** `HOLIDAY_AND_ADMIN_CONFIG_COMPLETE.md`
---
## 🎯 Next Steps
### **For Backend Developers:**
1. Test holiday API endpoints
2. Verify TAT calculations with holidays
3. Add more admin configurations as needed
### **For Frontend Developers:**
1. Build Admin Holiday Management UI
2. Create Holiday Calendar view
3. Implement Configuration Settings page
---
## 🔍 Verify Setup
### **Check Holidays Table:**
```sql
SELECT * FROM holidays;
-- Should return 0 rows (no holidays added yet)
```
### **Check Admin Configurations:**
```sql
SELECT * FROM admin_configurations;
-- Should return 0 rows (will be seeded on first use)
```
### **Test Holiday API:**
```bash
# Get all holidays for 2025
curl http://localhost:5000/api/admin/holidays?year=2025 \
-H "Authorization: Bearer YOUR_ADMIN_TOKEN"
```
---
## 📋 Sample Holidays Data
**File:** `data/indian_holidays_2025.json`
Contains 14 Indian national holidays for 2025:
- Republic Day (Jan 26)
- Holi
- Independence Day (Aug 15)
- Gandhi Jayanti (Oct 2)
- Diwali
- Christmas
- And more...
---
## ✅ Setup Status
| Component | Status | Notes |
|-----------|--------|-------|
| **Holidays Table** | ✅ Created | With 4 indexes |
| **Admin Config Table** | ✅ Created | With 3 indexes |
| **Holiday Model** | ✅ Implemented | Full CRUD support |
| **Holiday Service** | ✅ Implemented | Including bulk import |
| **Admin Controller** | ✅ Implemented | All endpoints ready |
| **Admin Routes** | ✅ Implemented | Secured with admin middleware |
| **TAT Integration** | ✅ Implemented | Holidays excluded for STANDARD |
| **Holiday Cache** | ✅ Implemented | 6-hour expiry, auto-refresh |
| **Sample Data** | ✅ Created | 14 holidays for 2025 |
| **Documentation** | ✅ Complete | Full guide available |
---
## 🎓 Example Usage
### **Create Request with Holiday in TAT Period:**
```javascript
// Create STANDARD priority request
POST /api/workflows
{
"title": "Test Request",
"priority": "STANDARD",
"approvers": [
{ "email": "approver@example.com", "tatHours": 48 }
]
}
// If holidays exist between now and +48 hours:
// - Due date will be calculated skipping those holidays
// - TAT calculation will be accurate
```
---
## 🛠️ Troubleshooting
### **Holidays not excluded from TAT?**
1. Check if holidays cache is loaded:
- Look for "Loaded X holidays into cache" in server logs
2. Verify priority is STANDARD (EXPRESS doesn't use holidays)
3. Check if holiday exists and is active:
```sql
SELECT * FROM holidays WHERE holiday_date = '2025-11-05' AND is_active = true;
```
### **Cache not updating after adding holiday?**
- Cache refreshes automatically when admin adds/updates/deletes holidays
- If not working, restart backend server
- Cache also refreshes every 6 hours automatically
---
## 📞 Support
For issues or questions:
1. Check documentation in `docs/` folder
2. Review complete guide in `HOLIDAY_AND_ADMIN_CONFIG_COMPLETE.md`
3. Consult with backend team
---
**🎉 You're all set! Start adding holidays and enjoy accurate TAT calculations!**

```
✅ **DONE!** You're ready to test!
---
## Test It Now (6 Minutes)
1. **Create a workflow request** via your frontend
2. **Set TAT: 6 hours** (will become 6 minutes in test mode)
3. **Submit the request**
4. **Watch for notifications**:
- **3 minutes**: ⏳ 50% notification
- **4.5 minutes**: ⚠️ 75% warning
- **6 minutes**: ⏰ 100% breach
---
## Verify It's Working
### Check Backend Logs:
```bash
# You should see:
[TAT Scheduler] Calculating TAT milestones...
[TAT Scheduler] ✅ TAT jobs scheduled
[TAT Processor] Processing tat50...
[TAT Processor] tat50 notification sent
```
### Check Upstash Console:
1. Go to https://console.upstash.com/
2. Click your database
3. Click "CLI" tab
4. Type: `KEYS bull:tatQueue:*`
5. Should see your scheduled jobs
### Check Database:
```sql
SELECT
approver_name,
tat50_alert_sent,
tat75_alert_sent,
tat_breached,
status
FROM approval_levels
WHERE status = 'IN_PROGRESS';
```
---
## What Test Mode Does
```
Normal Mode: Test Mode:
48 hours → 48 minutes
24 hours → 24 minutes
6 hours → 6 minutes
2 hours → 2 minutes
✅ Perfect for quick testing!
✅ Turn off for production: TAT_TEST_MODE=false
```
---
## Troubleshooting
### ❌ "ECONNREFUSED" Error?
**Fix**:
1. Check your `.env` file has `REDIS_URL=rediss://...`
2. Verify the URL is correct (copy from Upstash again)
3. Make sure it starts with `rediss://` (double 's')
4. Restart backend: `npm run dev`
### ❌ No Logs About Redis?
**Fix**:
1. Check `.env` file exists in `Re_Backend/` folder
2. Make sure you restarted the backend
3. Look for any errors in console
### ❌ Jobs Not Running?
**Fix**:
1. Verify `TAT_TEST_MODE=true` in `.env`
2. Make sure request is SUBMITTED (not just created)
3. Check Upstash Console → Metrics (see if commands are running)
---
## Next Steps
Once you see the first notification working:
1. ✅ Test multi-level approvals
2. ✅ Test early approval (jobs should cancel)
3. ✅ Test rejection flow
4. ✅ Check activity logs
5. ✅ Verify database flags

# ✅ TAT Alerts Display System - Complete Implementation
## 🎉 What's Been Implemented
Your TAT notification system now **stores every alert** in the database and **displays them in the UI** exactly like your shared screenshot!
---
## 📊 Complete Flow
### 1. When Request is Submitted
```typescript
// First level approver assigned
Level 1: John (TAT: 24 hours)
↓
TAT jobs scheduled for John:
- 50% alert (12 hours)
- 75% alert (18 hours)
- 100% breach (24 hours)
```
### 2. When Notification Fires (e.g., 50%)
**Backend (`tatProcessor.ts`):**
```typescript
✅ Send notification to John
✅ Create record in tat_alerts table
✅ Log activity
✅ Update approval_levels flags
```
**Database Record Created:**
```sql
INSERT INTO tat_alerts (
request_id, level_id, approver_id,
alert_type = 'TAT_50',
threshold_percentage = 50,
alert_message = '⏳ 50% of TAT elapsed...',
alert_sent_at = NOW(),
...
)
```
### 3. When Displayed in Frontend
**API Response** (`workflow.service.ts`):
```typescript
{
workflow: {...},
approvals: [...],
tatAlerts: [ // ← NEW!
{
alertType: 'TAT_50',
thresholdPercentage: 50,
alertSentAt: '2024-10-06T14:30:00Z',
alertMessage: '⏳ 50% of TAT elapsed...',
levelId: 'abc-123',
...
}
]
}
```
**Frontend Display** (`RequestDetail.tsx`):
```tsx
<div className="bg-yellow-50 border-yellow-200 p-3 rounded-lg">
⏳ Reminder 1
50% of SLA breach reminder have been sent
Reminder sent by system automatically
Sent at: Oct 6 at 2:30 PM
</div>
```
---

│ │
│ ⚠️ Reminder 2 │ ← TAT Alert #2
│ 75% of SLA breach reminder... │
│ Sent at: Oct 6 at 6:30 PM │
└────────────────────────────────────────┘
```
---
## 🔄 Complete Data Flow
### Backend:
1. **TAT Processor** (`tatProcessor.ts`):
- Sends notification to approver
- Creates record in `tat_alerts` table
- Logs activity
2. **Workflow Service** (`workflow.service.ts`):
- Fetches TAT alerts for request
- Includes in API response
- Groups by level ID
3. **Approval Service** (`approval.service.ts`):
- Updates alerts when level completed
- Sets `was_completed_on_time`
- Sets `completion_time`
### Frontend:
1. **Request Detail** (`RequestDetail.tsx`):
- Receives TAT alerts from API
- Filters alerts by level ID
- Displays under each approval level
- Color-codes by threshold
---
## 📊 Database Schema
### TAT Alerts Table:
```sql
SELECT
alert_type, -- TAT_50, TAT_75, TAT_100
threshold_percentage, -- 50, 75, 100
alert_sent_at, -- When alert was sent
alert_message, -- Full message text
level_id, -- Which approval level
approver_id, -- Who was notified
was_completed_on_time, -- Completed within TAT?
completion_time -- When completed
FROM tat_alerts
WHERE request_id = 'YOUR_REQUEST_ID'
ORDER BY alert_sent_at ASC;
```
---
## 🧪 Testing the Display
### Step 1: Setup Upstash Redis
See `START_HERE.md` for quick setup (2 minutes)
### Step 2: Enable Test Mode
In `.env`:
```bash
TAT_TEST_MODE=true
```
### Step 3: Create Test Request
- TAT: 6 hours (becomes 6 minutes in test mode)
- Submit the request
### Step 4: Watch Alerts Appear
**At 3 minutes (50%):**
```
⏳ Reminder 1
50% of SLA breach reminder have been sent
Reminder sent by system automatically
Sent at: [timestamp]
```
**At 4.5 minutes (75%):**
```
⚠️ Reminder 2
75% of SLA breach reminder have been sent
Reminder sent by system automatically
Sent at: [timestamp]
```
**At 6 minutes (100%):**
```
⏰ Reminder 3
100% of SLA breach reminder have been sent
Reminder sent by system automatically
Sent at: [timestamp]
```
### Step 5: Verify in Database
```sql
SELECT
threshold_percentage,
alert_sent_at,
was_completed_on_time,
completion_time
FROM tat_alerts
WHERE request_id = 'YOUR_REQUEST_ID'
ORDER BY threshold_percentage;
```
---
## 🎯 Approver-Specific Alerts
### Confirmation: Alerts are Approver-Specific
✅ **Each level's alerts** are sent to **that level's approver only**
✅ **Previous approver** does NOT receive alerts for next level
✅ **Current approver** receives all their level's alerts (50%, 75%, 100%)
### Example:
```
Request Flow:
Level 1: John (TAT: 24h)
→ Alerts sent to: John
→ At: 12h, 18h, 24h
Level 2: Sarah (TAT: 12h)
→ Alerts sent to: Sarah (NOT John)
→ At: 6h, 9h, 12h
Level 3: Mike (TAT: 8h)
→ Alerts sent to: Mike (NOT Sarah, NOT John)
→ At: 4h, 6h, 8h
```

## 🔍 Verify Implementation
### Check Backend Logs:
```bash
# When notification fires:
[TAT Processor] Processing tat50 for request...
[TAT Processor] TAT alert record created for tat50
[TAT Processor] tat50 notification sent
# When workflow details fetched:
[Workflow] Found 2 TAT alerts for request REQ-2024-001
```
### Check Database:
```sql
-- See all alerts for a request
SELECT * FROM tat_alerts
WHERE request_id = 'YOUR_REQUEST_ID'
ORDER BY alert_sent_at;
-- See alerts with approval info
SELECT
al.approver_name,
al.level_number,
ta.threshold_percentage,
ta.alert_sent_at,
ta.was_completed_on_time
FROM tat_alerts ta
JOIN approval_levels al ON ta.level_id = al.level_id
WHERE ta.request_id = 'YOUR_REQUEST_ID';
```
### Check Frontend:
1. Open Request Detail
2. Click "Workflow" tab
3. Look under each approval level card
4. You should see reminder boxes with:
- ⏳ 50% reminder (yellow background)
- ⚠️ 75% reminder (orange background)
- ⏰ 100% breach (red background)
---
## 📊 KPI Reporting Ready
### All TAT alerts are now queryable for KPIs:
**TAT Compliance Rate:**
```sql
SELECT
COUNT(CASE WHEN was_completed_on_time = true THEN 1 END) * 100.0 /
NULLIF(COUNT(*), 0) as compliance_rate
FROM tat_alerts
WHERE was_completed_on_time IS NOT NULL;
```
**Approver Response Time After Alert:**
```sql
SELECT
approver_id,
alert_type,
AVG(
EXTRACT(EPOCH FROM (completion_time - alert_sent_at)) / 3600
) as avg_hours_to_respond
FROM tat_alerts
WHERE completion_time IS NOT NULL
GROUP BY approver_id, alert_type;
```
**Breach Analysis:**
```sql
SELECT
DATE(alert_sent_at) as date,
COUNT(CASE WHEN alert_type = 'TAT_50' THEN 1 END) as alerts_50,
COUNT(CASE WHEN alert_type = 'TAT_75' THEN 1 END) as alerts_75,
COUNT(CASE WHEN alert_type = 'TAT_100' THEN 1 END) as breaches
FROM tat_alerts
WHERE alert_sent_at >= CURRENT_DATE - INTERVAL '30 days'
GROUP BY DATE(alert_sent_at)
ORDER BY date DESC;
```

## 📊 KPI Queries Using Alert Data
### **Average Response Time After Each Alert Type:**
```sql
SELECT
alert_type,
ROUND(AVG(tat_hours_elapsed), 2) as avg_elapsed,
ROUND(AVG(tat_hours_remaining), 2) as avg_remaining,
COUNT(*) as alert_count,
COUNT(CASE WHEN was_completed_on_time = true THEN 1 END) as completed_on_time
FROM tat_alerts
GROUP BY alert_type
ORDER BY threshold_percentage;
```
### **Approvers Who Frequently Breach:**
```sql
SELECT
u.display_name,
u.department,
COUNT(CASE WHEN ta.is_breached = true THEN 1 END) as breach_count,
AVG(ta.tat_hours_elapsed) as avg_time_taken,
COUNT(DISTINCT ta.level_id) as total_approvals
FROM tat_alerts ta
JOIN users u ON ta.approver_id = u.user_id
WHERE ta.is_breached = true
GROUP BY u.user_id, u.display_name, u.department
ORDER BY breach_count DESC
LIMIT 10;
```
### **Time-to-Action After Alert:**
```sql
SELECT
alert_type,
threshold_percentage,
ROUND(AVG(
EXTRACT(EPOCH FROM (completion_time - alert_sent_at)) / 3600
), 2) as avg_hours_to_respond_after_alert
FROM tat_alerts
WHERE completion_time IS NOT NULL
GROUP BY alert_type, threshold_percentage
ORDER BY threshold_percentage;
```
---
## 🔄 Alert Lifecycle
### **1. Alert Created (When Threshold Reached)**
```typescript
{
alertType: 'TAT_50',
thresholdPercentage: 50,
tatHoursAllocated: 12,
tatHoursElapsed: 6.0,
tatHoursRemaining: 6.0,
alertSentAt: '2024-10-06T14:30:00Z',
expectedCompletionTime: '2024-10-06T18:00:00Z',
isBreached: false,
wasCompletedOnTime: null, // Not completed yet
metadata: { testMode: true, ... }
}
```
### **2. Approver Takes Action**
```typescript
// Updated when level is approved/rejected
{
...existingFields,
wasCompletedOnTime: true, // or false
completionTime: '2024-10-06T16:00:00Z'
}
```
### **3. Displayed in UI**
```tsx
// Shows all historical alerts for that level
// Color-coded by threshold
// Shows completion status if completed
```
---
## 🎓 Understanding the Data
### **Allocated Hours (tat_hours_allocated)**
Total TAT time given to approver for this level
```
Example: 12 hours
Meaning: Approver has 12 hours to approve/reject
```
### **Elapsed Hours (tat_hours_elapsed)**
Time used when the alert was sent
```
Example: 6.0 hours (at 50% alert)
Meaning: 6 hours have passed since level started
```
### **Remaining Hours (tat_hours_remaining)**
Time left when the alert was sent
```
Example: 6.0 hours (at 50% alert)
Meaning: 6 hours remaining before TAT breach
Note: Turns red if < 2 hours
```
### **Expected Completion Time**
When the level should be completed
```
Example: Oct 6 at 6:00 PM
Meaning: Deadline for this approval level
```
---

# ⏰ TAT Notifications - Quick Start Guide
## 🎯 Goal
Get TAT (Turnaround Time) notifications working in **under 5 minutes**!
---
## ✅ Step 1: Setup Redis (Required)
### 🚀 Option A: Upstash (RECOMMENDED - No Installation!)
**Best for Windows/Development - 100% Free**
1. **Sign up**: Go to https://console.upstash.com/
2. **Create Database**: Click "Create Database"
- Name: `redis-tat-dev`
- Type: Regional
- Region: Choose closest to you
- Click "Create"
3. **Copy Connection URL**: You'll get a URL like:
```
rediss://default:AbCd1234...@us1-mighty-shark-12345.upstash.io:6379
```
4. **Update `.env` in Re_Backend/**:
```bash
REDIS_URL=rediss://default:AbCd1234...@us1-mighty-shark-12345.upstash.io:6379
```
✅ **Done!** No installation, no setup, works everywhere!
---
### Alternative: Docker (If you prefer local)
If you have Docker Desktop:
```bash
docker run -d --name redis-tat -p 6379:6379 redis:latest
```
Then in `.env`:
```bash
REDIS_URL=redis://localhost:6379
```
---
## ⚡ Step 2: Enable Test Mode (HIGHLY RECOMMENDED)
For testing, enable **fast mode** where **1 hour = 1 minute**:
### Edit `.env` file in `Re_Backend/`:
```bash
TAT_TEST_MODE=true
```
This means:
- ✅ 6-hour TAT = 6 minutes (instead of 6 hours)
- ✅ 48-hour TAT = 48 minutes (instead of 48 hours)
- ✅ Perfect for quick testing!
---
## 🚀 Step 3: Restart Backend
```bash
cd Re_Backend
npm run dev
```
### You Should See:
```
✅ [TAT Queue] Connected to Redis
✅ [TAT Worker] Initialized and listening
⏰ TAT Configuration:
- Test Mode: ENABLED (1 hour = 1 minute)
- Redis: rediss://***@upstash.io:6379
```
💡 If you see connection errors, double-check your `REDIS_URL` in `.env`
---
## 🧪 Step 4: Test It!
### Create a Request:
1. **Frontend**: Create a new workflow request
2. **Set TAT**: 6 hours (becomes 6 minutes in test mode)
3. **Submit** the request
### Watch the Magic:
```
✨ At 3 minutes: ⏳ 50% notification
✨ At 4.5 minutes: ⚠️ 75% notification
✨ At 6 minutes: ⏰ 100% breach notification
```
### Check Logs:
```bash
# You'll see:
[TAT Scheduler] ✅ TAT jobs scheduled for request...
[TAT Processor] Processing tat50 for request...
[TAT Processor] tat50 notification sent for request...
```
---
## 📊 Verify in Database
```sql
SELECT
approver_name,
tat_hours,
tat50_alert_sent,
tat75_alert_sent,
tat_breached,
status
FROM approval_levels
WHERE status = 'IN_PROGRESS';
```
You should see the flags change as notifications are sent!
---
## ❌ Troubleshooting
### "ECONNREFUSED" or Connection Error?
**Problem**: Can't connect to Redis
**Solution**:
1. **Check `.env` file**:
```bash
# Make sure REDIS_URL is set correctly
REDIS_URL=rediss://default:YOUR_PASSWORD@YOUR_URL.upstash.io:6379
```
2. **Verify Upstash Database**:
- Go to https://console.upstash.com/
- Check database status (should be "Active")
- Copy connection URL again if needed
3. **Test Connection**:
- Use Upstash's Redis CLI in their console
- Or install `redis-cli` and test:
```bash
redis-cli -u "rediss://default:YOUR_PASSWORD@YOUR_URL.upstash.io:6379" ping
# Should return: PONG
```
### No Notifications?
**Checklist**:
- ✅ REDIS_URL set in `.env`?
- ✅ Backend restarted after setting REDIS_URL?
- ✅ TAT_TEST_MODE=true in `.env`?
- ✅ Request submitted (not just created)?
- ✅ Logs show "Connected to Redis"?
### Still Issues?
```bash
# Check detailed logs
Get-Content Re_Backend/logs/app.log -Tail 50 -Wait
# Look for:
# ✅ [TAT Queue] Connected to Redis

---
## 🆘 Need Help?
Common fixes:
### 1. Verify Upstash Connection
```bash
# In Upstash Console (https://console.upstash.com/)
# - Click your database
# - Use the "CLI" tab to test: PING
# - Should return: PONG
```
### 2. Check Environment Variables
```bash
# In Re_Backend/.env, verify:
REDIS_URL=rediss://default:YOUR_PASSWORD@YOUR_URL.upstash.io:6379
TAT_TEST_MODE=true
```
### 3. Clear Redis Queue (if needed)
```bash
# In Upstash Console CLI tab:
FLUSHALL
# This clears all jobs - use only if you need a fresh start
```
### 4. Restart Backend
```bash
cd Re_Backend
npm run dev
```
### 5. Check Logs
```bash
Get-Content logs/app.log -Tail 50 -Wait
```
---
**Status Check**:
- [ ] Upstash Redis database created
- [ ] REDIS_URL copied to `.env`
- [ ] TAT_TEST_MODE=true in `.env`
- [ ] Backend restarted
- [ ] Logs show "TAT Queue: Connected to Redis"
- [ ] Test request submitted
✅ All checked? **You're ready!**

# 🔍 Troubleshooting TAT Alerts Not Showing
## Quick Diagnosis Steps
### Step 1: Check if Redis is Connected
**Look at your backend console when you start the server:**
✅ **Good** - Redis is working:
```
✅ [TAT Queue] Connected to Redis
✅ [TAT Worker] Worker is ready and listening
```
❌ **Bad** - Redis is NOT working:
```
⚠️ [TAT Worker] Redis connection failed
⚠️ [TAT Queue] Redis connection failed after 3 attempts
```
**If you see the bad message:**
→ TAT alerts will NOT be created because the worker isn't running
→ You MUST setup Redis first (see `START_HERE.md`)
---
### Step 2: Verify TAT Alerts Table Exists
**Run this SQL:**
```sql
SELECT COUNT(*) FROM tat_alerts;
```
**Expected Result:**
- If table exists: You'll see a count (maybe 0)
- If table doesn't exist: Error "relation tat_alerts does not exist"
**If table doesn't exist:**
```bash
cd Re_Backend
npm run migrate
```
---
### Step 3: Check if TAT Alerts Exist in Database
**Run this SQL:**
```sql
-- Check if ANY alerts exist
SELECT
ta.alert_id,
ta.threshold_percentage,
ta.alert_sent_at,
ta.alert_message,
ta.metadata->>'requestNumber' as request_number,
ta.metadata->>'approverName' as approver_name
FROM tat_alerts ta
ORDER BY ta.alert_sent_at DESC
LIMIT 10;
```
**If query returns 0 rows:**
→ No alerts have been created yet
→ This means:
1. Redis is not connected, OR
2. No requests have been submitted, OR
3. Not enough time has passed (wait 3 min in test mode)
---
### Step 4: Check API Response
**Option A: Use Debug Endpoint**
Call this URL in your browser or Postman:
```
GET http://localhost:5000/api/debug/tat-status
```
**You'll see:**
```json
{
"success": true,
"status": {
"redis": {
"configured": true,
"url": "rediss://****@upstash.io:6379",
"testMode": true
},
"database": {
"connected": true,
"tatAlertsTableExists": true,
"totalAlerts": 0
}
}
}
```
**Option B: Check Workflow Details Response**
For a specific request:
```
GET http://localhost:5000/api/debug/workflow-details/REQ-2025-XXXXX
```
**You'll see:**
```json
{
"success": true,
"structure": {
"hasTatAlerts": true,
"tatAlertsCount": 2
},
"tatAlerts": [
{
"alertType": "TAT_50",
"thresholdPercentage": 50,
"alertSentAt": "...",
...
}
]
}
```
---
### Step 5: Check Frontend Console
**Open browser DevTools (F12) → Console**
**When you open Request Detail, you should see:**
```javascript
// Look for the API response
Object {
workflow: {...},
approvals: [...],
tatAlerts: [...] // ← Check if this exists
}
```
**If `tatAlerts` is missing or empty:**
→ Backend is not returning it (go back to Step 3)
**If `tatAlerts` exists but not showing:**
→ Frontend rendering issue (check Step 6)
---
### Step 6: Verify Frontend Code
**Check if tatAlerts are being processed:**
Open `Re_Figma_Code/src/pages/RequestDetail/RequestDetail.tsx`
**Search for this line (around line 235 and 493):**
```typescript
const tatAlerts = Array.isArray(details.tatAlerts) ? details.tatAlerts : [];
```
**This should be there!** If not, the code wasn't applied.
**Then search for (around line 271 and 531):**
```typescript
const levelAlerts = tatAlerts.filter((alert: any) => alert.levelId === levelId);
```
**And in the JSX (around line 1070):**
```tsx
{step.tatAlerts && step.tatAlerts.length > 0 && (
<div className="mt-3 space-y-2">
{step.tatAlerts.map((alert: any, alertIndex: number) => (
```
---
## 🐛 Common Issues & Fixes
### Issue 1: "TAT alerts not showing in UI"
**Cause**: Redis not connected
**Fix**:
1. Setup Upstash: https://console.upstash.com/
2. Add to `.env`:
```bash
REDIS_URL=rediss://default:...@upstash.io:6379
TAT_TEST_MODE=true
```
3. Restart backend
4. Look for "Connected to Redis" in logs
---
### Issue 2: "tat_alerts table doesn't exist"
**Cause**: Migrations not run
**Fix**:
```bash
cd Re_Backend
npm run migrate
```
---
### Issue 3: "No alerts in database"
**Cause**: No requests submitted or not enough time passed
**Fix**:
1. Create a new workflow request
2. **SUBMIT** the request (not just save as draft)
3. Wait:
- Test mode: 3 minutes for 50% alert
- Production: Depends on TAT (e.g., 12 hours for 24-hour TAT)
---
### Issue 4: "tatAlerts is undefined in API response"
**Cause**: Backend code not updated
**Fix**:
Check `Re_Backend/src/services/workflow.service.ts` line 698:
```typescript
return { workflow, approvals, participants, documents, activities, summary, tatAlerts };
// ^^^^^^^^
// Make sure tatAlerts is included!
```
---
### Issue 5: "Frontend not displaying alerts even though they exist"
**Cause**: Frontend code not applied or missing key
**Fix**:
1. Check browser console for errors
2. Verify `step.tatAlerts` is defined in approval flow
3. Check if alerts have correct `levelId` matching approval level
---
## 📊 Manual Test Steps
### Step-by-Step Debugging:
**1. Check Redis Connection:**
```bash
# Start backend and look for:
✅ [TAT Queue] Connected to Redis
```
**2. Create and Submit Request:**
```bash
# Via frontend or API:
POST /api/workflows/create
POST /api/workflows/{id}/submit
```
**3. Wait for Alert (Test Mode):**
```bash
# For 6-hour TAT in test mode:
# Wait 3 minutes for 50% alert
```
**4. Check Database:**
```sql
SELECT * FROM tat_alerts ORDER BY alert_sent_at DESC LIMIT 5;
```
**5. Check API Response:**
```bash
GET /api/workflows/{requestNumber}/details
# Look for tatAlerts array in response
```
**6. Check Frontend:**
```javascript
// Open DevTools Console
// Navigate to Request Detail
// Check the console log for API response
```
---
## 🔧 Debug Commands
### Check TAT System Status:
```bash
curl http://localhost:5000/api/debug/tat-status
```
### Check Workflow Details for Specific Request:
```bash
curl http://localhost:5000/api/debug/workflow-details/REQ-2025-XXXXX
```
### Check Database Directly:
```sql
-- Total alerts
SELECT COUNT(*) FROM tat_alerts;
-- Alerts for specific request
SELECT * FROM tat_alerts
WHERE request_id = (
SELECT request_id FROM workflow_requests
WHERE request_number = 'REQ-2025-XXXXX'
);
-- Pending levels that should get alerts
SELECT
w.request_number,
al.approver_name,
al.status,
al.tat_start_time,
CASE
WHEN al.tat_start_time IS NULL THEN 'No TAT monitoring started'
ELSE 'TAT monitoring active'
END as tat_status
FROM approval_levels al
JOIN workflow_requests w ON al.request_id = w.request_id
WHERE al.status IN ('PENDING', 'IN_PROGRESS');
```
---

# ❓ Why Are TAT Alerts Not Showing?
## 🎯 Follow These Steps IN ORDER
### ✅ Step 1: Is Redis Connected?
**Check your backend console:**
```
Look for one of these messages:
```
**✅ GOOD (Redis is working):**
```
✅ [TAT Queue] Connected to Redis
✅ [TAT Worker] Worker is ready and listening
```
**❌ BAD (Redis NOT working):**
```
⚠️ [TAT Worker] Redis connection failed
⚠️ [TAT Queue] Redis connection failed after 3 attempts
```
**If you see the BAD message:**
→ **STOP HERE!** TAT alerts will NOT work without Redis!
→ **Setup Upstash Redis NOW:**
1. Go to: https://console.upstash.com/
2. Sign up (free)
3. Create database
4. Copy Redis URL
5. Add to `Re_Backend/.env`:
```bash
REDIS_URL=rediss://default:PASSWORD@host.upstash.io:6379
TAT_TEST_MODE=true
```
6. Restart backend
7. Verify you see "Connected to Redis"
---
### ✅ Step 2: Have You Submitted a Request?
**TAT monitoring starts ONLY when:**
- ✅ Request is **SUBMITTED** (not just created/saved)
- ✅ Status changes from DRAFT → PENDING
**To verify:**
```sql
SELECT
request_number,
status,
submission_date
FROM workflow_requests
WHERE request_number = 'YOUR_REQUEST_NUMBER';
```
**Check:**
- `status` should be `PENDING`, `IN_PROGRESS`, or later
- `submission_date` should NOT be NULL
**If status is DRAFT:**
→ Click "Submit" button on the request
→ TAT monitoring will start
---
### ✅ Step 3: Has Enough Time Passed?
**In TEST MODE (TAT_TEST_MODE=true):**
- 1 hour = 1 minute
- For 6-hour TAT:
- 50% alert at: **3 minutes**
- 75% alert at: **4.5 minutes**
- 100% breach at: **6 minutes**
**In PRODUCTION MODE:**
- 1 hour = 1 hour (real time)
- For 24-hour TAT:
- 50% alert at: **12 hours**
- 75% alert at: **18 hours**
- 100% breach at: **24 hours**
**Check when request was submitted:**
```sql
SELECT
request_number,
submission_date,
NOW() - submission_date as time_since_submission
FROM workflow_requests
WHERE request_number = 'YOUR_REQUEST_NUMBER';
```
---
### ✅ Step 4: Are Alerts in the Database?
**Run this SQL:**
```sql
-- Check if table exists
SELECT COUNT(*) FROM tat_alerts;
-- If table exists, check for your request
SELECT
ta.threshold_percentage,
ta.alert_sent_at,
ta.alert_message,
ta.metadata
FROM tat_alerts ta
JOIN workflow_requests w ON ta.request_id = w.request_id
WHERE w.request_number = 'YOUR_REQUEST_NUMBER'
ORDER BY ta.alert_sent_at;
```
**Expected Result:**
- **0 rows** → No alerts sent yet (wait longer OR Redis not connected)
- **1+ rows** → Alerts exist! (Go to Step 5)
**If table doesn't exist:**
```bash
cd Re_Backend
npm run migrate
```
---
### ✅ Step 5: Is API Returning tatAlerts?
**Test the API directly:**
**Method 1: Use Debug Endpoint**
```bash
curl http://localhost:5000/api/debug/workflow-details/YOUR_REQUEST_NUMBER
```
**Look for:**
```json
{
"structure": {
"hasTatAlerts": true, ← Should be true
"tatAlertsCount": 2 ← Should be > 0
},
"tatAlerts": [...] ← Should have data
}
```
**Method 2: Check Network Tab in Browser**
1. Open Request Detail page
2. Open DevTools (F12) → Network tab
3. Find the API call to `/workflows/{requestNumber}/details`
4. Click on it
5. Check Response tab
6. Look for `tatAlerts` array
---
### ✅ Step 6: Is Frontend Receiving tatAlerts?
**Open Browser Console (F12 → Console)**
**When you open Request Detail, you should see:**
```javascript
[RequestDetail] TAT Alerts received from API: 2 [Array(2)]
```
**If you see:**
```javascript
[RequestDetail] TAT Alerts received from API: 0 []
```
→ API is NOT returning alerts (go back to Step 4)
---
### ✅ Step 7: Are Alerts Being Displayed?
**In Request Detail:**
1. Click **"Workflow" tab**
2. Scroll to the approver card
3. Look under the approver's comment section
**You should see yellow/orange/red boxes with:**
```
⏳ Reminder 1 - 50% TAT Threshold
```
**If you DON'T see them:**
→ Check browser console for JavaScript errors
---
## 🔍 Quick Diagnostic
**Run ALL of these and share the results:**
### 1. Backend Status:
```bash
curl http://localhost:5000/api/debug/tat-status
```
### 2. Database Query:
```sql
SELECT COUNT(*) as total FROM tat_alerts;
```
### 3. Browser Console:
```javascript
// Open Request Detail
// Check console for:
[RequestDetail] TAT Alerts received from API: X [...]
```
### 4. Network Response:
```
DevTools → Network → workflow details call → Response tab
Look for "tatAlerts" field
```
---
## 🎯 Most Likely Issues (In Order)
### 1. Redis Not Connected (90% of cases)
**Symptom**: No "Connected to Redis" in logs
**Fix**: Setup Upstash, add REDIS_URL, restart
### 2. Request Not Submitted (5%)
**Symptom**: Request status is DRAFT
**Fix**: Click Submit button
### 3. Not Enough Time Passed (3%)
**Symptom**: Submitted < 3 minutes ago (in test mode)
**Fix**: Wait 3 minutes for first alert
### 4. TAT Worker Not Running (1%)
**Symptom**: Redis connected but no "Worker is ready" message
**Fix**: Restart backend server
### 5. Frontend Code Not Applied (1%)
**Symptom**: API returns tatAlerts but UI doesn't show them
**Fix**: Refresh browser, clear cache
---
## 🚨 Emergency Checklist
**Do this RIGHT NOW to verify everything:**
```bash
# 1. Check backend console for Redis connection
# Look for: ✅ [TAT Queue] Connected to Redis
# 2. If NOT connected, setup Upstash:
# https://console.upstash.com/
# 3. Add to .env:
# REDIS_URL=rediss://...
# TAT_TEST_MODE=true
# 4. Restart backend
npm run dev
# 5. Check you see "Connected to Redis"
# 6. Create NEW request with 6-hour TAT
# 7. SUBMIT the request
# 8. Wait 3 minutes
# 9. Open browser console (F12)
# 10. Open Request Detail page
# 11. Check console log for:
# [RequestDetail] TAT Alerts received from API: X [...]
# 12. Go to Workflow tab
# 13. Alerts should appear!
```

## 📞 Share These for Help
If still not working, share:
1. **Backend console output** (first 50 lines after starting)
2. **Result of**: `curl http://localhost:5000/api/debug/tat-status`
3. **SQL result**: `SELECT COUNT(*) FROM tat_alerts;`
4. **Browser console** when opening Request Detail
5. **Request number** you're testing with
6. **How long ago** was the request submitted?
---
## ✅ Working Example
**When everything works, you'll see:**
**Backend Console:**
```
✅ [TAT Queue] Connected to Redis
✅ [TAT Worker] Worker is ready
[TAT Scheduler] ✅ TAT jobs scheduled for request REQ-2025-001
```
**After 3 minutes (test mode):**
```
[TAT Processor] Processing tat50 for request REQ-2025-001
[TAT Processor] TAT alert record created for tat50
[TAT Processor] tat50 notification sent
```
**Browser Console:**
```javascript
[RequestDetail] TAT Alerts received from API: 1 [
{
alertType: "TAT_50",
thresholdPercentage: 50,
alertSentAt: "2025-11-04T...",
...
}
]
```
**UI Display:**
```
⏳ Reminder 1 - 50% TAT Threshold
50% of SLA breach reminder have been sent
...
```

## 📅 Holiday Calendar System - Complete Guide
## Overview
The Holiday Calendar System allows administrators to manage organizational holidays that are excluded from TAT (Turnaround Time) calculations for **STANDARD priority** requests.
**Key Features:**
- ✅ Admin can add/edit/delete holidays
- ✅ Supports different holiday types (National, Regional, Organizational, Optional)
- ✅ Recurring holidays (e.g., Independence Day every year)
- ✅ Department/location-specific holidays
- ✅ Bulk import from CSV/JSON
- ✅ Automatic integration with TAT calculations
- ✅ Year-based calendar view
---
## 🎯 How It Works
### **For STANDARD Priority:**
```
Working Days = Monday-Friday (excluding weekends AND holidays)
TAT Calculation = Skips Saturdays, Sundays, AND holidays
```
### **For EXPRESS Priority:**
```
Calendar Days = All days (including weekends and holidays)
TAT Calculation = Continuous (no skipping)
```
---
## 📊 Database Schema
### **Holidays Table:**
```sql
CREATE TABLE holidays (
holiday_id UUID PRIMARY KEY,
holiday_date DATE NOT NULL UNIQUE,
holiday_name VARCHAR(200) NOT NULL,
description TEXT,
is_recurring BOOLEAN DEFAULT false,
recurrence_rule VARCHAR(100), -- For annual recurring
holiday_type ENUM('NATIONAL', 'REGIONAL', 'ORGANIZATIONAL', 'OPTIONAL'),
is_active BOOLEAN DEFAULT true,
applies_to_departments TEXT[], -- NULL = all departments
applies_to_locations TEXT[], -- NULL = all locations
created_by UUID REFERENCES users(user_id),
updated_by UUID REFERENCES users(user_id),
created_at TIMESTAMP,
updated_at TIMESTAMP
);
```
---
## 🔌 API Endpoints
### **1. Get All Holidays**
```

---
## 🎨 Frontend Implementation (Future)
### **Holiday Management Page:**
```tsx
// Admin Dashboard → Settings → Holiday Calendar
<HolidayCalendar>
<YearSelector currentYear={2025} />
<CalendarView>
{/* Visual calendar showing all holidays */}
<Day date="2025-01-26" isHoliday>
Republic Day
</Day>
</CalendarView>
<HolidayList>
{/* List view with add/edit/delete */}
<HolidayCard>
📅 Jan 26, 2025 - Republic Day
<Actions>
<EditButton />
<DeleteButton />
</Actions>
</HolidayCard>
</HolidayList>
<AddHolidayButton onClick={openModal} />
<BulkImportButton onClick={openImportDialog} />
</HolidayCalendar>
```
---
## 📝 Sample Holidays Data
### **Indian National Holidays 2025:**
```json
[
{ "date": "2025-01-26", "name": "Republic Day", "type": "NATIONAL" },
{ "date": "2025-03-14", "name": "Holi", "type": "NATIONAL" },
{ "date": "2025-03-30", "name": "Ram Navami", "type": "NATIONAL" },
{ "date": "2025-04-10", "name": "Mahavir Jayanti", "type": "NATIONAL" },
{ "date": "2025-04-14", "name": "Ambedkar Jayanti", "type": "NATIONAL" },
{ "date": "2025-04-18", "name": "Good Friday", "type": "NATIONAL" },
{ "date": "2025-05-01", "name": "May Day", "type": "NATIONAL" },
{ "date": "2025-08-15", "name": "Independence Day", "type": "NATIONAL" },
{ "date": "2025-08-27", "name": "Janmashtami", "type": "NATIONAL" },

{ "date": "2025-12-25", "name": "Christmas", "type": "NATIONAL" }
]
```
---
## 🔄 TAT Calculation Integration
### **How Holidays Affect TAT:**
**Example: 48-hour TAT for STANDARD priority**
**Without Holidays:**
```
Submit: Monday 10:00 AM
Due: Wednesday 10:00 AM (48 working hours, skipping weekend)
```
**With Holiday (Tuesday is holiday):**
```
Submit: Monday 10:00 AM
Holiday: Tuesday (skipped)
Due: Thursday 10:00 AM (48 working hours, skipping Tuesday AND weekend)
```
### **TAT Calculation Logic:**
```typescript
// For STANDARD priority:
1. Start from submission time
2. Add hours one by one
3. Skip if:
- Weekend (Saturday/Sunday)
- Outside working hours (before 9 AM or after 6 PM)
- Holiday (from holidays table)
4. Continue until all hours are added
```
---
## 🏗️ Architecture
### **Holiday Cache System:**
```
Server Startup
↓
Load holidays from database
↓
Cache in memory (Set of dates)
↓
Cache expires after 6 hours
↓
Reload automatically
```
**Benefits:**
- ✅ Fast lookups (no DB query for each hour)
- ✅ Automatic refresh
- ✅ Minimal memory footprint
### **TAT Calculation Flow:**
```
calculateTatMilestones()
↓
addWorkingHours()
↓
loadHolidaysCache() (if expired)
↓
For each hour:
isWorkingTime()
├─ Check weekend? → Skip
├─ Check working hours? → Skip if outside
└─ Check holiday? → Skip if holiday
↓
Return calculated date
```

## 📋 Admin Configuration
### **Admin Can Configure:**
| Config Area | Options | Default |
|-------------|---------|---------|
| **TAT Settings** | Default TAT hours (Express/Standard) | 24h/48h |
| | Reminder thresholds | 50%, 75% |
| | Working hours | 9 AM - 6 PM |
| **Holidays** | Add/edit/delete holidays | None |
| | Bulk import holidays | - |
| | Recurring holidays | - |
| **Document Policy** | Max file size | 10 MB |
| | Allowed file types | pdf,doc,... |
| | Retention period | 365 days |
| **AI Configuration** | Enable/disable AI remarks | Enabled |
| | Max characters | 500 |
| **Notifications** | Channels (email/push) | All |
| | Frequency | Immediate |
---
## 🧪 Testing Holiday Integration
### **Test Scenario 1: Add Holiday**
```bash
# 1. Add a holiday for tomorrow
POST /api/admin/holidays
{
"holidayDate": "2025-11-05",
"holidayName": "Test Holiday",
"holidayType": "ORGANIZATIONAL"
}
# 2. Create request with 24-hour STANDARD TAT
# Expected: Due date should skip the holiday
# 3. Verify TAT calculation excludes the holiday
```
### **Test Scenario 2: Recurring Holiday**
```bash
# 1. Add Independence Day (recurring)
POST /api/admin/holidays
{
"holidayDate": "2025-08-15",
"holidayName": "Independence Day",
"isRecurring": true,
"recurrenceRule": "FREQ=YEARLY;BYMONTH=8;BYMONTHDAY=15"
}
# 2. Test requests spanning this date
```
---
## 📊 Holiday Statistics API
### **Get Holiday Count by Type:**
```sql
SELECT
holiday_type,
COUNT(*) as count
FROM holidays
WHERE is_active = true
AND EXTRACT(YEAR FROM holiday_date) = 2025
GROUP BY holiday_type;
```
### **Get Upcoming Holidays:**
```sql
SELECT
holiday_name,
holiday_date,
holiday_type
FROM holidays
WHERE holiday_date >= CURRENT_DATE
AND holiday_date <= CURRENT_DATE + INTERVAL '90 days'
AND is_active = true
ORDER BY holiday_date;
```
---
## 🔒 Security
### **Admin Only Access:**
All holiday and configuration management endpoints require:
1. ✅ Valid JWT token (`authenticateToken`)
2. ✅ Admin role (`requireAdmin`)
**Middleware Chain:**
```typescript
router.use(authenticateToken); // Must be logged in
router.use(requireAdmin); // Must be admin
```
---
## 🎓 Best Practices
### **1. Holiday Naming:**
- Use clear, descriptive names
- Include year if not recurring
- Example: "Diwali 2025" or "Independence Day" (recurring)
### **2. Types:**
- **NATIONAL**: Applies to entire country
- **REGIONAL**: Specific to state/region
- **ORGANIZATIONAL**: Company-specific
- **OPTIONAL**: Optional holidays (float)
### **3. Department/Location Specific:**
```json
{
"holidayName": "Regional Holiday",
"appliesToDepartments": ["Sales", "Marketing"],
"appliesToLocations": ["Mumbai", "Delhi"]
}
```
### **4. Recurring Holidays:**
```json
{
"isRecurring": true,
"recurrenceRule": "FREQ=YEARLY;BYMONTH=8;BYMONTHDAY=15"
}
```
---
## 🚀 Deployment
### **Initial Setup:**
1. **Run Migrations:**
```bash
npm run migrate
```
2. **Import Indian Holidays:**
```bash
curl -X POST http://localhost:5000/api/admin/holidays/bulk-import \
-H "Content-Type: application/json" \
-H "Authorization: Bearer YOUR_ADMIN_TOKEN" \
-d @sample_holidays_2025.json
```
3. **Verify:**
```bash
curl http://localhost:5000/api/admin/holidays?year=2025
```

# KPI Reporting System - Complete Guide
## Overview
This document describes the complete KPI (Key Performance Indicator) reporting system for the Royal Enfield Workflow Management System, including database schema, views, and query examples.
---
## 📊 Database Schema
### 1. TAT Alerts Table (`tat_alerts`)
**Purpose**: Store all TAT notification records for display and KPI analysis
```sql
CREATE TABLE tat_alerts (
alert_id UUID PRIMARY KEY,
request_id UUID REFERENCES workflow_requests(request_id),
level_id UUID REFERENCES approval_levels(level_id),
approver_id UUID REFERENCES users(user_id),
alert_type ENUM('TAT_50', 'TAT_75', 'TAT_100'),
threshold_percentage INTEGER, -- 50, 75, or 100
tat_hours_allocated DECIMAL(10,2),
tat_hours_elapsed DECIMAL(10,2),
tat_hours_remaining DECIMAL(10,2),
level_start_time TIMESTAMP,
alert_sent_at TIMESTAMP DEFAULT NOW(),
expected_completion_time TIMESTAMP,
alert_message TEXT,
notification_sent BOOLEAN DEFAULT true,
notification_channels TEXT[], -- ['push', 'email', 'sms']
is_breached BOOLEAN DEFAULT false,
was_completed_on_time BOOLEAN, -- Set when level completed
completion_time TIMESTAMP,
metadata JSONB DEFAULT '{}',
created_at TIMESTAMP DEFAULT NOW()
);
```
**Key Features**:
- ✅ Tracks every TAT notification sent (50%, 75%, 100%)
- ✅ Records timing information for KPI calculation
- ✅ Stores completion status for compliance reporting
- ✅ Metadata includes request title, approver name, priority

## 📊 KPI Dashboard Queries
### Executive Dashboard
```sql
-- Overall KPIs for dashboard cards
SELECT
(SELECT COUNT(*) FROM vw_request_volume_summary WHERE created_at >= DATE_TRUNC('month', CURRENT_DATE)) as requests_this_month,
(SELECT COUNT(*) FROM vw_request_volume_summary WHERE status_category = 'IN_PROGRESS') as open_requests,
(SELECT ROUND(AVG(cycle_time_hours / 24), 2) FROM vw_request_volume_summary WHERE closure_date IS NOT NULL) as avg_cycle_days,
(SELECT ROUND(COUNT(CASE WHEN completed_within_tat = true THEN 1 END) * 100.0 / NULLIF(COUNT(*), 0), 2) FROM vw_tat_compliance WHERE completed_within_tat IS NOT NULL) as tat_compliance_percent;
```
---
## 🚀 API Endpoint Examples
### Example Service Method (TypeScript)
```typescript
// services/kpi.service.ts
export class KPIService {
/**
* Get Request Volume Summary
*/
async getRequestVolumeSummary(startDate: string, endDate: string) {
const query = `
SELECT
status_category,
COUNT(*) as count
FROM vw_request_volume_summary
WHERE created_at BETWEEN :startDate AND :endDate
GROUP BY status_category
`;
return await sequelize.query(query, {
replacements: { startDate, endDate },
type: QueryTypes.SELECT
});
}
/**
* Get TAT Compliance Rate
*/
async getTATComplianceRate(period: 'daily' | 'weekly' | 'monthly') {
const query = `
SELECT
COUNT(CASE WHEN completed_within_tat = true THEN 1 END) * 100.0 /
NULLIF(COUNT(*), 0) as compliance_rate
FROM vw_tat_compliance
WHERE action_date >= NOW() - INTERVAL '1 ${period}'
`;
return await sequelize.query(query, { type: QueryTypes.SELECT });
}
/**
* Get TAT Alerts for Request
*/
async getTATAlertsForRequest(requestId: string) {
return await TatAlert.findAll({
where: { requestId },
order: [['alertSentAt', 'ASC']],
include: [
{ model: ApprovalLevel, as: 'level' },
{ model: User, as: 'approver' }
]
});
}
}
```
---
## 📋 Maintenance & Performance
### Indexes
All views use indexed columns for optimal performance:
- `request_id`, `level_id`, `approver_id`
- `status`, `created_at`, `alert_sent_at`
- `is_deleted` (for soft deletes)
### Refresh Materialized Views (if needed)
If you convert views to materialized views for better performance:
```sql
-- Refresh all materialized views
REFRESH MATERIALIZED VIEW CONCURRENTLY mv_request_volume_summary;
REFRESH MATERIALIZED VIEW CONCURRENTLY mv_tat_compliance;
-- etc.
```

# TAT (Turnaround Time) Notification System
## Overview
The TAT Notification System automatically tracks and notifies approvers about their approval deadlines at key milestones (50%, 75%, and 100% of allotted time). It uses a queue-based architecture with BullMQ and Redis to ensure reliable, scheduled notifications.
## Architecture
```
┌─────────────────┐
│ Workflow │
│ Submission │
└────────┬────────┘
│
├──> Schedule TAT Jobs (50%, 75%, 100%)
│
┌────────▼────────┐ ┌──────────────┐ ┌─────────────┐
│ TAT Queue │────>│ TAT Worker │────>│ Processor │
│ (BullMQ) │ │ (Background)│ │ Handler │
└─────────────────┘ └──────────────┘ └──────┬──────┘
│
├──> Send Notification
├──> Update Database
└──> Log Activity
```
## Components
### 1. TAT Time Utilities (`tatTimeUtils.ts`)
Handles working hours calculations (Monday-Friday, 9 AM - 6 PM):
```typescript
// Calculate TAT milestones considering working hours
const { halfTime, seventyFive, full } = calculateTatMilestones(startDate, tatHours);
```
**Key Functions:**
- `addWorkingHours()`: Adds working hours to a start date, skipping weekends
- `calculateTatMilestones()`: Calculates 50%, 75%, and 100% time points
- `calculateDelay()`: Computes delay in milliseconds from now to target
### 2. TAT Queue (`tatQueue.ts`)
BullMQ queue configuration with Redis:
```typescript
export const tatQueue = new Queue('tatQueue', {
connection: IORedis,
defaultJobOptions: {
removeOnComplete: true,
removeOnFail: false,
attempts: 3,
backoff: { type: 'exponential', delay: 2000 }
}
});
```
### 3. TAT Processor (`tatProcessor.ts`)
Handles job execution when TAT milestones are reached:
```typescript
export async function handleTatJob(job: Job<TatJobData>) {
// Process tat50, tat75, or tatBreach
// - Send notification to approver
// - Update database flags
// - Log activity
}
```
**Job Types:**
- `tat50`: ⏳ 50% of TAT elapsed (gentle reminder)
- `tat75`: ⚠️ 75% of TAT elapsed (escalation warning)
- `tatBreach`: ⏰ 100% of TAT elapsed (breach notification)
### 4. TAT Worker (`tatWorker.ts`)
Background worker that processes jobs from the queue:
```typescript
export const tatWorker = new Worker('tatQueue', handleTatJob, {
connection,
concurrency: 5,
limiter: { max: 10, duration: 1000 }
});
```
**Features:**
- Concurrent job processing (up to 5 jobs)
- Rate limiting (10 jobs/second)
- Automatic retry on failure
- Graceful shutdown on SIGTERM/SIGINT
### 5. TAT Scheduler Service (`tatScheduler.service.ts`)
Service for scheduling and managing TAT jobs:
```typescript
// Schedule TAT jobs for an approval level
await tatSchedulerService.scheduleTatJobs(
requestId,
levelId,
approverId,
tatHours,
startTime
);
// Cancel TAT jobs when level is completed
await tatSchedulerService.cancelTatJobs(requestId, levelId);
```
## Database Schema
### New Fields in `approval_levels` Table
```sql
ALTER TABLE approval_levels ADD COLUMN tat50_alert_sent BOOLEAN NOT NULL DEFAULT false;
ALTER TABLE approval_levels ADD COLUMN tat75_alert_sent BOOLEAN NOT NULL DEFAULT false;
ALTER TABLE approval_levels ADD COLUMN tat_breached BOOLEAN NOT NULL DEFAULT false;
ALTER TABLE approval_levels ADD COLUMN tat_start_time TIMESTAMP WITH TIME ZONE;
```
**Field Descriptions:**
- `tat50_alert_sent`: Tracks if 50% notification was sent
- `tat75_alert_sent`: Tracks if 75% notification was sent
- `tat_breached`: Tracks if TAT deadline was breached
- `tat_start_time`: Timestamp when TAT monitoring started
## Integration Points
### 1. Workflow Submission
When a workflow is submitted, TAT monitoring starts for the first approval level:
```typescript
// workflow.service.ts - submitWorkflow()
await current.update({
levelStartTime: now,
tatStartTime: now,
status: ApprovalStatus.IN_PROGRESS
});
await tatSchedulerService.scheduleTatJobs(
requestId,
levelId,
approverId,
tatHours,
now
);
```
### 2. Approval Flow
When a level is approved, TAT jobs are cancelled and new ones are scheduled for the next level:
```typescript
// approval.service.ts - approveLevel()
// Cancel current level TAT jobs
await tatSchedulerService.cancelTatJobs(requestId, levelId);
// Schedule TAT jobs for next level
await tatSchedulerService.scheduleTatJobs(
nextRequestId,
nextLevelId,
nextApproverId,
nextTatHours,
now
);
```
### 3. Rejection Flow
When a level is rejected, all pending TAT jobs are cancelled:
```typescript
// approval.service.ts - approveLevel()
await tatSchedulerService.cancelTatJobs(requestId, levelId);
```
## Notification Flow
### 50% TAT Alert (⏳)
**Message:** "50% of TAT elapsed for Request REQ-XXX: [Title]"
**Actions:**
- Send push notification to approver
- Update `tat50_alert_sent = true`
- Update `tat_percentage_used = 50`
- Log activity: "50% of TAT time has elapsed"
### 75% TAT Alert (⚠️)
**Message:** "75% of TAT elapsed for Request REQ-XXX: [Title]. Please take action soon."
**Actions:**
- Send push notification to approver
- Update `tat75_alert_sent = true`
- Update `tat_percentage_used = 75`
- Log activity: "75% of TAT time has elapsed - Escalation warning"
### 100% TAT Breach (⏰)
**Message:** "TAT breached for Request REQ-XXX: [Title]. Immediate action required!"
**Actions:**
- Send push notification to approver
- Update `tat_breached = true`
- Update `tat_percentage_used = 100`
- Log activity: "TAT deadline reached - Breach notification"
## Configuration
### Environment Variables
```bash
# Redis connection for TAT queue
REDIS_URL=redis://localhost:6379
# Optional: TAT monitoring settings
TAT_CHECK_INTERVAL_MINUTES=30
TAT_REMINDER_THRESHOLD_1=50
TAT_REMINDER_THRESHOLD_2=80
```
### Docker Compose
Redis service is automatically configured:
```yaml
redis:
image: redis:7-alpine
container_name: re_workflow_redis
ports:
- "6379:6379"
volumes:
- redis_data:/data
networks:
- re_workflow_network
restart: unless-stopped
```
## Working Hours Configuration
**Default Schedule:**
- Working Days: Monday - Friday
- Working Hours: 9:00 AM - 6:00 PM (9 hours/day)
- Timezone: Server timezone
**To Modify:**
Edit `WORK_START_HOUR` and `WORK_END_HOUR` in `tatTimeUtils.ts`
## Example Scenario
### Scenario: 48-hour TAT Approval
1. **Workflow Submitted**: Monday 10:00 AM
2. **50% Alert (24 hours)**: Tuesday 10:00 AM
- Notification sent to approver
- Database updated: `tat50_alert_sent = true`
3. **75% Alert (36 hours)**: Wednesday 10:00 AM
- Escalation warning sent
- Database updated: `tat75_alert_sent = true`
4. **100% Breach (48 hours)**: Thursday 10:00 AM
- Breach alert sent
- Database updated: `tat_breached = true`
## Error Handling
### Queue Job Failures
- **Automatic Retry**: Failed jobs retry up to 3 times with exponential backoff
- **Error Logging**: All failures logged to console and logs
- **Non-Blocking**: TAT failures don't block workflow approval process
### Redis Connection Failures
- **Graceful Degradation**: Application continues to work even if Redis is down
- **Reconnection**: Automatic reconnection attempts
- **Logging**: Connection status logged
## Monitoring & Debugging
### Check Queue Status
```bash
# View jobs in Redis
redis-cli
> KEYS bull:tatQueue:*
> LRANGE bull:tatQueue:delayed 0 -1
```
### View Worker Logs
```bash
# Check worker status in application logs
grep "TAT Worker" logs/app.log
grep "TAT Scheduler" logs/app.log
grep "TAT Processor" logs/app.log
```
### Database Queries
```sql
-- Check TAT status for all approval levels
SELECT
level_id,
request_id,
approver_name,
tat_hours,
tat_percentage_used,
tat50_alert_sent,
tat75_alert_sent,
tat_breached,
level_start_time,
tat_start_time
FROM approval_levels
WHERE status IN ('PENDING', 'IN_PROGRESS');
-- Find breached TATs
SELECT * FROM approval_levels WHERE tat_breached = true;
```
## Best Practices
1. **Always Schedule on Level Start**: Ensure `tatStartTime` is set when a level becomes active
2. **Always Cancel on Level Complete**: Cancel jobs when level is approved/rejected to avoid duplicate notifications
3. **Use Job IDs**: Unique job IDs (`tat50-{requestId}-{levelId}`) allow easy cancellation
4. **Monitor Queue Health**: Regularly check Redis and worker status
5. **Test with Short TATs**: Use short TAT durations in development for testing
## Troubleshooting
### Notifications Not Sent
1. Check Redis connection: `redis-cli ping`
2. Verify worker is running: Check logs for "TAT Worker: Initialized"
3. Check job scheduling: Look for "TAT jobs scheduled" logs
4. Verify VAPID configuration for push notifications
### Duplicate Notifications
1. Ensure jobs are cancelled when level is completed
2. Check for duplicate job IDs in Redis
3. Verify `tat50_alert_sent` and `tat75_alert_sent` flags
### Jobs Not Executing
1. Check system time (jobs use timestamps)
2. Verify working hours calculation
3. Check job delays in Redis
4. Review worker concurrency and rate limits
## Future Enhancements
1. **Configurable Working Hours**: Allow per-organization working hours
2. **Holiday Calendar**: Skip public holidays in TAT calculations
3. **Escalation Rules**: Auto-escalate to manager on breach
4. **TAT Dashboard**: Real-time visualization of TAT statuses
5. **Email Notifications**: Add email alerts alongside push notifications
6. **SMS Notifications**: Critical breach alerts via SMS
## API Endpoints (Future)
Potential API endpoints for TAT management:
```
GET /api/tat/status/:requestId - Get TAT status for request
GET /api/tat/breaches - List all breached requests
POST /api/tat/extend/:levelId - Extend TAT for a level
GET /api/tat/analytics - TAT analytics and reports
```

# TAT Notification Testing Guide
## Quick Setup for Testing
### Step 1: Setup Redis
**You MUST have Redis for TAT notifications to work.**
#### 🚀 Option A: Upstash (RECOMMENDED - No Installation!)
**Best choice for Windows development:**
1. Go to: https://console.upstash.com/
2. Sign up (free)
3. Create Database:
- Name: `redis-tat-dev`
- Type: Regional
- Region: Choose closest
4. Copy Redis URL (format: `rediss://default:...@host.upstash.io:6379`)
5. Add to `Re_Backend/.env`:
```bash
REDIS_URL=rediss://default:YOUR_PASSWORD@YOUR_HOST.upstash.io:6379
```
**✅ Done!** No installation, works everywhere!
See detailed guide: `docs/UPSTASH_SETUP_GUIDE.md`
#### Option B: Docker (If you prefer local)
```bash
docker run -d --name redis-tat -p 6379:6379 redis:latest
```
Then in `.env`:
```bash
REDIS_URL=redis://localhost:6379
```
#### Option C: Linux Production
```bash
sudo apt install redis-server -y
sudo systemctl start redis-server
```
#### Verify Connection
- **Upstash**: Use Console CLI → `PING` → should return `PONG`
- **Local**: `Test-NetConnection localhost -Port 6379`
---
### Step 2: Enable Test Mode (Optional but Recommended)
For faster testing, enable test mode where **1 hour = 1 minute**:
1. **Edit your `.env` file**:
```bash
TAT_TEST_MODE=true
```
2. **Restart your backend**:
```bash
cd Re_Backend
npm run dev
```
3. **Verify test mode is enabled** - You should see:
```
⏰ TAT Configuration:
- Test Mode: ENABLED (1 hour = 1 minute)
- Working Hours: 9:00 - 18:00
- Working Days: Monday - Friday
- Redis: redis://localhost:6379
```
---
### Step 3: Create a Test Workflow
#### Production Mode (TAT_TEST_MODE=false)
- Create a request with **2 hours TAT**
- Notifications will come at:
- **1 hour** (50%)
- **1.5 hours** (75%)
- **2 hours** (100% breach)
#### Test Mode (TAT_TEST_MODE=true) ⚡ FASTER
- Create a request with **6 hours TAT** (becomes 6 minutes)
- Notifications will come at:
- **3 minutes** (50%)
- **4.5 minutes** (75%)
- **6 minutes** (100% breach)
---
### Step 4: Submit and Monitor
1. **Create and Submit Request** via your frontend or API
2. **Check Backend Logs** - You should see:
```
[TAT Scheduler] Calculating TAT milestones for request...
[TAT Scheduler] Start: 2025-11-04 12:00
[TAT Scheduler] 50%: 2025-11-04 12:03
[TAT Scheduler] 75%: 2025-11-04 12:04
[TAT Scheduler] 100%: 2025-11-04 12:06
[TAT Scheduler] Scheduled tat50 for level...
[TAT Scheduler] Scheduled tat75 for level...
[TAT Scheduler] Scheduled tatBreach for level...
[TAT Scheduler] ✅ TAT jobs scheduled for request...
```
3. **Wait for Notifications**
- Watch the logs
- Check push notifications
- Verify database updates
4. **Verify Notifications** - Look for:
```
[TAT Processor] Processing tat50 for request...
[TAT Processor] tat50 notification sent for request...
```
---
## Testing Scenarios
### Scenario 1: Normal Flow (Happy Path)
```
1. Create request with TAT = 6 hours (6 min in test mode)
2. Submit request
3. Wait for 50% notification (3 min)
4. Wait for 75% notification (4.5 min)
5. Wait for 100% breach (6 min)
```
**Expected Result:**
- ✅ 3 notifications sent
- ✅ Database flags updated
- ✅ Activity logs created
---
### Scenario 2: Early Approval
```
1. Create request with TAT = 6 hours
2. Submit request
3. Wait for 50% notification (3 min)
4. Approve immediately
5. Remaining notifications should be cancelled
```
**Expected Result:**
- ✅ 50% notification received
- ✅ 75% and 100% notifications cancelled
- ✅ TAT jobs for next level scheduled
---
### Scenario 3: Multi-Level Approval
```
1. Create request with 3 approval levels (2 hours each)
2. Submit request
3. Level 1: Wait for notifications, then approve
4. Level 2: Should schedule new TAT jobs
5. Level 2: Wait for notifications, then approve
6. Level 3: Should schedule new TAT jobs
```
**Expected Result:**
- ✅ Each level gets its own TAT monitoring
- ✅ Previous level jobs cancelled on approval
- ✅ New level jobs scheduled
---
### Scenario 4: Rejection
```
1. Create request with TAT = 6 hours
2. Submit request
3. Wait for 50% notification
4. Reject the request
5. All remaining notifications should be cancelled
```
**Expected Result:**
- ✅ TAT jobs cancelled
- ✅ No further notifications
---
## Verification Checklist
### Backend Logs ✅
```bash
# Should see these messages:
✓ [TAT Queue] Connected to Redis
✓ [TAT Worker] Initialized and listening
✓ [TAT Scheduler] TAT jobs scheduled
✓ [TAT Processor] Processing tat50
✓ [TAT Processor] tat50 notification sent
```
### Database Check ✅
```sql
-- Check approval level TAT status
SELECT
request_id,
level_number,
approver_name,
tat_hours,
tat_percentage_used,
tat50_alert_sent,
tat75_alert_sent,
tat_breached,
tat_start_time,
status
FROM approval_levels
WHERE request_id = '<YOUR_REQUEST_ID>';
```
**Expected Fields:**
- `tat_start_time`: Should be set when level starts
- `tat50_alert_sent`: true after 50% notification
- `tat75_alert_sent`: true after 75% notification
- `tat_breached`: true after 100% notification
- `tat_percentage_used`: 50, 75, or 100
### Activity Logs ✅
```sql
-- Check activity timeline
SELECT
activity_type,
activity_description,
user_name,
created_at
FROM activities
WHERE request_id = '<YOUR_REQUEST_ID>'
ORDER BY created_at DESC;
```
**Expected Entries:**
- "50% of TAT time has elapsed"
- "75% of TAT time has elapsed - Escalation warning"
- "TAT deadline reached - Breach notification"
### Redis Queue ✅
```bash
# Connect to Redis
redis-cli
# Check scheduled jobs
KEYS bull:tatQueue:*
LRANGE bull:tatQueue:delayed 0 -1
# Check job details
HGETALL bull:tatQueue:tat50-<REQUEST_ID>-<LEVEL_ID>
```
---
## Troubleshooting
### ❌ No Notifications Received
**Problem:** TAT jobs scheduled but no notifications
**Solutions:**
1. Check Redis is running:
```powershell
Test-NetConnection localhost -Port 6379
```
2. Check worker is running:
```bash
# Look for in backend logs:
[TAT Worker] Worker is ready and listening
```
3. Check job delays:
```bash
redis-cli
> LRANGE bull:tatQueue:delayed 0 -1
```
4. Verify VAPID keys for push notifications:
```bash
# In .env file:
VAPID_PUBLIC_KEY=...
VAPID_PRIVATE_KEY=...
```
---
### ❌ Jobs Not Executing
**Problem:** Jobs scheduled but never execute
**Solutions:**
1. Check system time is correct
2. Verify test mode settings
3. Check worker logs for errors
4. Restart worker:
```bash
# Restart backend server
npm run dev
```
---
### ❌ Duplicate Notifications
**Problem:** Receiving multiple notifications for same milestone
**Solutions:**
1. Check database flags are being set:
```sql
SELECT tat50_alert_sent, tat75_alert_sent FROM approval_levels;
```
2. Verify job cancellation on approval:
```bash
# Should see in logs:
[Approval] TAT jobs cancelled for level...
```
3. Check for duplicate job IDs in Redis
---
### ❌ Redis Connection Errors
**Problem:** `ECONNREFUSED` errors
**Solutions:**
1. **Start Redis** - See Step 1
2. Check Redis URL in `.env`:
```bash
REDIS_URL=redis://localhost:6379
```
3. Verify port 6379 is not blocked:
```powershell
Test-NetConnection localhost -Port 6379
```
---

Test-NetConnection localhost -Port 6379
# 2. Start Backend (with test mode)
cd Re_Backend
$env:TAT_TEST_MODE="true"
npm run dev
# 3. Monitor Logs (in another terminal)
cd Re_Backend
Get-Content -Path "logs/app.log" -Wait -Tail 50
# 4. Check Redis Jobs
redis-cli KEYS "bull:tatQueue:*"
# 5. Query Database
psql -U laxman -d re_workflow_db -c "SELECT * FROM approval_levels WHERE tat_start_time IS NOT NULL;"
```
---
## Support
If you encounter issues:
1. **Check Logs**: `Re_Backend/logs/`
2. **Enable Debug**: Set `LOG_LEVEL=debug` in `.env`
3. **Redis Status**: `redis-cli ping` should return `PONG`
4. **Worker Status**: Look for "TAT Worker: Initialized" in logs
5. **Database**: Verify TAT fields exist in `approval_levels` table

## Why Upstash?
✅ **No Installation**: Works instantly on Windows, Mac, Linux
✅ **100% Free Tier**: 10,000 commands/day (more than enough for dev)
✅ **Production Ready**: Same service for dev and production
✅ **Global CDN**: Fast from anywhere
✅ **Zero Maintenance**: No Redis server to manage
---
## Step-by-Step Setup (3 minutes)
### 1. Create Upstash Account
1. Go to: https://console.upstash.com/
2. Sign up with GitHub, Google, or Email
3. Verify your email (if required)
### 2. Create Redis Database
1. **Click "Create Database"**
2. **Fill in details**:
- **Name**: `redis-tat-dev` (or any name you like)
- **Type**: Select "Regional"
- **Region**: Choose closest to you (e.g., US East, EU West)
- **TLS**: Keep enabled (recommended)
- **Eviction**: Choose "No Eviction"
3. **Click "Create"**
### 3. Copy Connection URL
After creation, you'll see your database dashboard:
1. **Find "REST API" section**
2. **Look for "Redis URL"** - it looks like:
```
rediss://default:AbCdEfGh1234567890XyZ@us1-mighty-shark-12345.upstash.io:6379
```
3. **Click the copy button** 📋
---
## Configure Your Application
### Edit `.env` File
Open `Re_Backend/.env` and add/update:
```bash
# Upstash Redis URL
REDIS_URL=rediss://default:YOUR_PASSWORD@YOUR_URL.upstash.io:6379
# Enable test mode for faster testing
TAT_TEST_MODE=true
```
**Important**:
- Note the **double `s`** in `rediss://` (TLS enabled)
- Copy the entire URL including the password
---
## Verify Connection
### Start Your Backend
```bash
cd Re_Backend
npm run dev
```
### Check Logs
You should see:
```
✅ [TAT Queue] Connected to Redis
✅ [TAT Worker] Initialized and listening
⏰ TAT Configuration:
- Test Mode: ENABLED (1 hour = 1 minute)
- Redis: rediss://***@upstash.io:6379
```
---
## Test Using Upstash Console
### Method 1: Web CLI (Easiest)
1. Go to your database in Upstash Console
2. Click the **"CLI"** tab
3. Type commands:
```redis
PING
# → PONG
KEYS *
# → Shows all keys (should see TAT jobs after submitting request)
INFO
# → Shows Redis server info
```
### Method 2: Redis CLI (Optional)
If you have `redis-cli` installed:
```bash
redis-cli -u "rediss://default:YOUR_PASSWORD@YOUR_URL.upstash.io:6379" ping
# → PONG
```
---
## Monitor Your TAT Jobs
### View Queued Jobs
In Upstash Console CLI:
```redis
# List all TAT jobs
KEYS bull:tatQueue:*
# See delayed jobs
LRANGE bull:tatQueue:delayed 0 -1
# Get specific job details
HGETALL bull:tatQueue:tat50-<REQUEST_ID>-<LEVEL_ID>
```
### Example Output
After submitting a request, you should see:
```redis
KEYS bull:tatQueue:*
# Returns:
# 1) "bull:tatQueue:id"
# 2) "bull:tatQueue:delayed"
# 3) "bull:tatQueue:tat50-abc123-xyz789"
# 4) "bull:tatQueue:tat75-abc123-xyz789"
# 5) "bull:tatQueue:tatBreach-abc123-xyz789"
```

**Perfect for:**
- ✅ Development
- ✅ Testing
- ✅ Small production apps (up to ~100 users)
---
## Production Considerations
### Upgrade When Needed
For production with high traffic:
- **Pro Plan**: $0.2 per 100K commands
- **Pay as you go**: No monthly fee
- **Auto-scaling**: Handles any load
### Security Best Practices
1. **Use TLS**: Always use `rediss://` (double s)
2. **Rotate Passwords**: Change regularly in production
3. **IP Restrictions**: Add allowed IPs in Upstash console
4. **Environment Variables**: Never commit REDIS_URL to Git
### Production Setup
```bash
# .env.production
REDIS_URL=rediss://default:PROD_PASSWORD@prod-region.upstash.io:6379
TAT_TEST_MODE=false # Use real hours in production
WORK_START_HOUR=9
WORK_END_HOUR=18
```
---
## Troubleshooting
### Connection Refused Error
**Problem**: `ECONNREFUSED` or timeout
**Solutions**:
1. **Check URL format**:
```bash
# Should be:
rediss://default:password@host.upstash.io:6379
# NOT:
redis://... (missing second 's' for TLS)
```
2. **Verify database is active**:
- Go to Upstash Console
- Check database status (should be green "Active")
3. **Test connection**:
- Use Upstash Console CLI tab
- Type `PING` - should return `PONG`
### Slow Response Times
**Problem**: High latency
**Solutions**:
1. **Choose closer region**:
- Delete database
- Create new one in region closer to you
2. **Use REST API** (alternative):
```bash
UPSTASH_REDIS_REST_URL=https://YOUR_URL.upstash.io
UPSTASH_REDIS_REST_TOKEN=YOUR_TOKEN
```
### Command Limit Exceeded
**Problem**: "Daily request limit exceeded"
**Solutions**:
1. **Check usage**:
- Go to Upstash Console → Metrics
- See command count
2. **Optimize**:
- Remove unnecessary Redis calls
- Batch operations where possible
3. **Upgrade** (if needed):
- Pro plan: $0.2 per 100K commands
- No monthly fee

## Comparison: Upstash vs Local Redis
| Feature | Upstash | Local Redis |
|---------|---------|-------------|
| **Setup Time** | 2 minutes | 10-30 minutes |
| **Installation** | None | Docker/Memurai |
| **Maintenance** | Zero | Manual updates |
| **Cost (Dev)** | Free | Free |
| **Works Offline** | No | Yes |
| **Production** | Same setup | Need migration |
| **Monitoring** | Built-in | Setup required |
| **Backup** | Automatic | Manual |
**Verdict**:
- ✅ **Upstash for most cases** (especially Windows dev)
- Local Redis only if you need offline development
---
## Migration from Local Redis
If you were using local Redis:
### 1. Export Data (Optional)
```bash
# From local Redis
redis-cli --rdb dump.rdb
# Import to Upstash (use Upstash REST API or CLI)
```
### 2. Update Configuration
```bash
# Old (.env)
REDIS_URL=redis://localhost:6379
# New (.env)
REDIS_URL=rediss://default:PASSWORD@host.upstash.io:6379
```
### 3. Restart Application
```bash
npm run dev
```
**That's it!** No code changes needed - BullMQ works identically.
---
