# ✅ Auto-Migration Setup Complete
## 🎯 What Was Done
### 1. Converted SQL Migration to TypeScript
**Before**: `src/migrations/add_is_skipped_to_approval_levels.sql` (manual SQL)
**After**: `src/migrations/20251105-add-skip-fields-to-approval-levels.ts` (TypeScript)
**Features Added to `approval_levels` table**:
- ✅ `is_skipped` - Boolean flag to track skipped approvers
- ✅ `skipped_at` - Timestamp when approver was skipped
- ✅ `skipped_by` - Foreign key to user who skipped
- ✅ `skip_reason` - Text field for skip justification
- ✅ Partial index on `is_skipped = TRUE` for query performance
- ✅ Full rollback support in `down()` function
### 2. Updated Migration Runner
**File**: `src/scripts/migrate.ts`
**Changes**:
- Added import for new migration (m14)
- Added execution in run() function
- Enhanced console output with emojis for better visibility
- Better error messages
### 3. Auto-Run Migrations on Development Start
**File**: `package.json`
**Before**:
```json
"dev": "nodemon --exec ts-node -r tsconfig-paths/register src/server.ts"
```
**After**:
```json
"dev": "npm run migrate && nodemon --exec ts-node -r tsconfig-paths/register src/server.ts"
```
**What This Means**:
- 🔄 Migrations run automatically before server starts
- ✅ No more manual migration steps
- 🛡️ Server won't start if migrations fail
- ⚡ Fresh database schema on every dev restart
### 4. Created Documentation
- 📘 `MIGRATION_WORKFLOW.md` - Complete migration guide
- 📗 `MIGRATION_QUICK_REFERENCE.md` - Quick reference card
- 📕 `AUTO_MIGRATION_SETUP_COMPLETE.md` - This file
## 🚀 How to Use
### Starting Development (Most Common)
```bash
npm run dev
```
This will:
1. Connect to database
2. Run all 14 migrations sequentially
3. Start development server with hot reload
4. Display success messages
**Expected Output**:
```
📦 Database connected
🔄 Running migrations...
✅ Created workflow_requests table
✅ Created approval_levels table
...
✅ Added skip-related fields to approval_levels table
✅ All migrations applied successfully
🚀 Server running on port 5000
```
### Running Migrations Only
```bash
npm run migrate
```
Use when you want to update database without starting server.

## 🔄 Adding Future Migrations
When you need to add a new migration:
### Step 1: Create File
```bash
# Create file: src/migrations/20251106-your-description.ts
```
### Step 2: Write Migration
```typescript
import { QueryInterface, DataTypes } from 'sequelize';
export async function up(queryInterface: QueryInterface): Promise<void> {
// Your changes here
await queryInterface.addColumn('table', 'column', {
type: DataTypes.STRING
});
console.log('✅ Your migration completed');
}
export async function down(queryInterface: QueryInterface): Promise<void> {
// Rollback here
await queryInterface.removeColumn('table', 'column');
console.log('✅ Rollback completed');
}
```
### Step 3: Register in migrate.ts
```typescript
// Add at top
import * as m15 from '../migrations/20251106-your-description';
// Add in run() function after m14
await (m15 as any).up(sequelize.getQueryInterface());
```
### Step 4: Test
```bash
npm run migrate
# or
npm run dev
```
## 🎯 Benefits
### For Development
- ✅ **No manual steps** - migrations run automatically
- ✅ **Consistent state** - everyone on team has same schema
- ✅ **Error prevention** - server won't start with schema mismatch
- ✅ **Fast iteration** - add migration, restart, test
### For Production
- ✅ **Idempotent** - safe to run multiple times
- ✅ **Versioned** - migrations tracked in git
- ✅ **Rollback support** - down() functions for reverting
- ✅ **Error handling** - clear failure messages
### For Team
- ✅ **TypeScript** - type-safe migrations
- ✅ **Documentation** - comprehensive guides
- ✅ **Best practices** - professional .NET team standards
- ✅ **Clear workflow** - easy to onboard new developers
## 🛡️ Safety Features
### Migration Execution
- Stops on first error
- Exits with error code 1 on failure
- Prevents server startup if migrations fail
- Detailed error logging
### Idempotency
All migrations should be idempotent (safe to run multiple times):
```typescript
// Check before adding
const tableDesc = await queryInterface.describeTable('table');
if (!tableDesc.column) {
await queryInterface.addColumn(/* ... */);
}
```
### Transactions
For complex migrations, wrap in transaction:
```typescript
const transaction = await queryInterface.sequelize.transaction();
try {
await queryInterface.addColumn(/* ... */, { transaction });
await queryInterface.addIndex(/* ... */, { transaction });
await transaction.commit();
} catch (error) {
await transaction.rollback();
throw error;
}
```
## 📝 Database Structure Reference
Always refer to **`backend_structure.txt`** for:
- Current table schemas
- Column types and constraints
- Foreign key relationships
- Enum values
- Index definitions
## 🧪 Testing the Setup
### Test Migration System
```bash
# Run migrations
npm run migrate
# Should see:
# 📦 Database connected
# 🔄 Running migrations...
# ✅ [migration messages]
# ✅ All migrations applied successfully
```
### Test Auto-Run on Dev
```bash
# Start development
npm run dev
# Should see migrations run, then:
# 🚀 Server running on port 5000
# 📊 Environment: development
# ...
```
### Test New Migration
1. Create test migration file
2. Register in migrate.ts
3. Run `npm run dev`
4. Verify migration executed
5. Check database schema
## 🎓 Pro Tips
1. **Always test locally first** - never test migrations in production
2. **Backup before migrating** - especially in production
3. **Keep migrations atomic** - one logical change per file
4. **Write descriptive names** - make purpose clear
5. **Add comments** - explain why, not just what
6. **Test rollbacks** - verify down() functions work
7. **Update documentation** - keep backend_structure.txt current
8. **Review before committing** - migrations are permanent

## 🎯 Usage in Code
### Backend
```typescript
import { SYSTEM_CONFIG } from '@config/system.config';
// Access configuration
const maxLevels = SYSTEM_CONFIG.WORKFLOW.MAX_APPROVAL_LEVELS;
const workStart = SYSTEM_CONFIG.WORKING_HOURS.START_HOUR;
```
### Frontend
```typescript
import { configService } from '@/services/configService';
// Async usage
const config = await configService.getConfig();
const maxFileSize = config.upload.maxFileSizeMB;
// Helper functions
import { getWorkingHours, getTATThresholds } from '@/services/configService';
const workingHours = await getWorkingHours();
```
---
## 🔐 Security Best Practices
1. **Never commit `.env`** with real credentials
2. **Use strong JWT secrets** (min 32 characters)
3. **Rotate secrets regularly** in production
4. **Use environment-specific configs** for dev/staging/prod
5. **Store secrets in secure vaults** (AWS Secrets Manager, Azure Key Vault)
---
## 📝 Configuration Checklist
### Before Deployment
- [ ] Set `NODE_ENV=production`
- [ ] Configure database with SSL
- [ ] Set strong JWT secret
- [ ] Disable TAT test mode
- [ ] Configure email SMTP
- [ ] Set up Redis connection
- [ ] Configure file storage (local/S3/GCS)
- [ ] Test working hours match business hours
- [ ] Verify TAT thresholds are correct
- [ ] Enable/disable feature flags as needed
---
## 🛠️ Adding New Configuration
1. Add to `system.config.ts`:
```typescript
export const SYSTEM_CONFIG = {
// ...existing config
MY_NEW_SETTING: {
VALUE: process.env.MY_VALUE || 'default',
},
};
```
2. Add to `getPublicConfig()` if needed on frontend:
```typescript
export function getPublicConfig() {
return {
// ...existing
myNewSetting: SYSTEM_CONFIG.MY_NEW_SETTING,
};
}
```
3. Access in code:
```typescript
const value = SYSTEM_CONFIG.MY_NEW_SETTING.VALUE;
```

# Dynamic TAT Thresholds Implementation
## Problem Statement
### Original Issue
The TAT system had **hardcoded threshold percentages** (50%, 75%, 100%) which created several problems:
1. **Job Naming Conflict**: Jobs were named using threshold percentages (`tat50-{reqId}-{levelId}`)
2. **Configuration Changes Didn't Apply**: Changing threshold in settings didn't affect scheduled jobs
3. **Message Mismatch**: Messages always said "50% elapsed" even if admin configured 55%
4. **Cancellation Issues**: Uncertainty about whether jobs could be properly cancelled after config changes
### Critical Edge Case Identified by User
**Scenario:**
```
1. Request created → TAT jobs scheduled:
- tat50-REQ123-LEVEL456 (fires at 8 hours, says "50% elapsed")
- tat75-REQ123-LEVEL456 (fires at 12 hours)
- tatBreach-REQ123-LEVEL456 (fires at 16 hours)
2. Admin changes threshold from 50% → 55%
3. User approves at 9 hours (after old 50% fired)
→ Job already fired with "50% elapsed" message ❌
→ But admin configured 55% ❌
→ Inconsistent!
4. Even if approval happens before old 50%:
→ System cancels `tat50-REQ123-LEVEL456` ✅
→ But message would still say "50%" (hardcoded) ❌
```
---
## Solution: Generic Job Names + Dynamic Thresholds
### 1. **Generic Job Naming**
Changed from percentage-based to generic names:
**Before:**
```typescript
tat50-{requestId}-{levelId}
tat75-{requestId}-{levelId}
tatBreach-{requestId}-{levelId}
```
**After:**
```typescript
tat-threshold1-{requestId}-{levelId} // First threshold (configurable: 50%, 55%, 60%, etc.)
tat-threshold2-{requestId}-{levelId} // Second threshold (configurable: 75%, 80%, etc.)
tat-breach-{requestId}-{levelId} // Always 100% (deadline)
```
### 2. **Store Threshold in Job Data**
Instead of relying on job name, we store the actual percentage in job payload:
```typescript
interface TatJobData {
type: 'threshold1' | 'threshold2' | 'breach';
threshold: number; // Actual % (e.g., 55, 80, 100)
requestId: string;
levelId: string;
approverId: string;
}
```
### 3. **Dynamic Message Generation**
Messages use the threshold from job data:
```typescript
case 'threshold1':
message = `⏳ ${threshold}% of TAT elapsed for Request ${requestNumber}`;
// If threshold = 55, message says "55% of TAT elapsed" ✅
```
### 4. **Configuration Cache Management**
- Configurations are cached for 5 minutes (performance)
- Cache is **automatically cleared** when admin updates settings
- Next scheduled job will use new thresholds
---
## How It Solves the Edge Cases
### ✅ **Case 1: Config Changed After Job Creation**
**Scenario:**
```
1. Request created with TAT = 16 hours (thresholds: 50%, 75%)
Jobs scheduled:
- tat-threshold1-REQ123 → fires at 8h, threshold=50
- tat-threshold2-REQ123 → fires at 12h, threshold=75
2. Admin changes threshold from 50% → 55%
3. Old request jobs STILL fire at 8h (50%)
✅ BUT message correctly shows "50% elapsed" (from job data)
✅ No confusion because that request WAS scheduled at 50%
4. NEW requests created after config change:
Jobs scheduled:
- tat-threshold1-REQ456 → fires at 8.8h, threshold=55 ✅
- tat-threshold2-REQ456 → fires at 12h, threshold=75
5. Message says "55% of TAT elapsed" ✅ CORRECT!
```
**Result:**
- ✅ Existing jobs maintain their original thresholds (consistent)
- ✅ New jobs use updated thresholds (respects config changes)
- ✅ Messages always match actual threshold used
---
### ✅ **Case 2: User Approves Before Threshold**
**Scenario:**
```
1. Job scheduled: tat-threshold1-REQ123 (fires at 55%)
2. User approves at 40% elapsed
3. cancelTatJobs('REQ123', 'LEVEL456') is called:
→ Looks for: tat-threshold1-REQ123-LEVEL456 ✅ FOUND
→ Removes job ✅ SUCCESS
4. No notification sent ✅ CORRECT!
```
**Result:**
- ✅ Generic names allow consistent cancellation
- ✅ Works regardless of threshold percentage
- ✅ No ambiguity in job identification
---
### ✅ **Case 3: User Approves After Threshold Fired**
**Scenario:**
```
1. Job scheduled: tat-threshold1-REQ123 (fires at 55%)
2. Job fires at 55% → notification sent
3. User approves at 60%
4. cancelTatJobs called:
→ Tries to cancel tat-threshold1-REQ123
→ Job already processed and removed (removeOnComplete: true)
→ No error (gracefully handled) ✅
5. Later jobs (threshold2, breach) are still cancelled ✅
```
**Result:**
- ✅ Already-fired jobs don't cause errors
- ✅ Remaining jobs are still cancelled
- ✅ System behaves correctly in all scenarios
---
## Configuration Flow
### **Admin Updates Threshold**
```
1. Admin changes "First TAT Threshold" from 50% → 55%
↓
2. Frontend sends: PUT /api/v1/admin/configurations/TAT_REMINDER_THRESHOLD_1
Body: { configValue: '55' }
↓
3. Backend updates database:
UPDATE admin_configurations
SET config_value = '55'
WHERE config_key = 'TAT_REMINDER_THRESHOLD_1'
↓
4. Backend clears config cache:
clearConfigCache() ✅
↓
5. Next request created:
- getTatThresholds() → reads '55' from DB
- Schedules job at 55% (8.8 hours for 16h TAT)
- Job data: { threshold: 55 }
↓
6. Job fires at 55%:
- Message: "55% of TAT elapsed" ✅ CORRECT!
```
---
## Database Impact
### **No Database Changes Required!**
The `admin_configurations` table already has all required fields:
- ✅ `TAT_REMINDER_THRESHOLD_1` → First threshold (50% default)
- ✅ `TAT_REMINDER_THRESHOLD_2` → Second threshold (75% default)
### **Job Queue Data Structure**
**Old Job Data:**
```json
{
"type": "tat50",
"requestId": "...",
"levelId": "...",
"approverId": "..."
}
```
**New Job Data:**
```json
{
"type": "threshold1",
"threshold": 55,
"requestId": "...",
"levelId": "...",
"approverId": "..."
}
```
---
## Testing Scenarios
### **Test 1: Change Threshold, Create New Request**
```bash
# 1. Change threshold from 50% to 55%
curl -X PUT http://localhost:5000/api/v1/admin/configurations/TAT_REMINDER_THRESHOLD_1 \
-H "Authorization: Bearer TOKEN" \
-H "Content-Type: application/json" \
-d '{"configValue": "55"}'
# 2. Create new workflow request
# → Jobs scheduled at 55%, 75%, 100%
# 3. Wait for 55% elapsed
# → Notification says "55% of TAT elapsed" ✅
```
### **Test 2: Approve Before Threshold**
```bash
# 1. Request created (TAT = 16 hours)
# → threshold1 scheduled at 8.8 hours (55%)
# 2. Approve at 6 hours (before 55%)
curl -X POST http://localhost:5000/api/v1/workflows/REQ123/approve/LEVEL456
# 3. cancelTatJobs is called internally
# → tat-threshold1-REQ123-LEVEL456 removed ✅
# → tat-threshold2-REQ123-LEVEL456 removed ✅
# → tat-breach-REQ123-LEVEL456 removed ✅
# 4. No notifications sent ✅
```
### **Test 3: Mixed Old and New Jobs**
```bash
# 1. Create Request A with old threshold (50%)
# → Jobs use threshold=50
# 2. Admin changes to 55%
# 3. Create Request B with new threshold (55%)
# → Jobs use threshold=55
# 4. Both requests work correctly:
# → Request A fires at 50%, message says "50%" ✅
# → Request B fires at 55%, message says "55%" ✅
```
---
## Summary
### **What Changed:**
1. ✅ Job names: `tat50` → `tat-threshold1` (generic)
2. ✅ Job data: Now includes actual threshold percentage
3. ✅ Messages: Dynamic based on threshold from job data
4. ✅ Scheduling: Reads thresholds from database configuration
5. ✅ Cache: Automatically cleared on config update
### **What Didn't Change:**
1. ✅ Database schema (admin_configurations already has all needed fields)
2. ✅ API endpoints (no breaking changes)
3. ✅ Frontend UI (works exactly the same)
4. ✅ Cancellation logic (still works, just uses new names)
### **Benefits:**
1. ✅ **No Job Name Conflicts**: Generic names work for any percentage
2. ✅ **Accurate Messages**: Always show actual threshold used
3. ✅ **Config Flexibility**: Admin can change thresholds anytime
4. ✅ **Backward Compatible**: Existing jobs complete normally
5. ✅ **Reliable Cancellation**: Works regardless of threshold value
6. ✅ **Immediate Effect**: New requests use updated thresholds immediately

## Configuration Keys
| Key | Description | Default | Example |
|-----|-------------|---------|---------|
| `TAT_REMINDER_THRESHOLD_1` | First warning threshold | 50 | 55 (sends alert at 55%) |
| `TAT_REMINDER_THRESHOLD_2` | Critical warning threshold | 75 | 80 (sends alert at 80%) |
| Breach | Deadline reached (always 100%) | 100 | 100 (non-configurable) |
---
## Example Timeline
**TAT = 16 hours, Thresholds: 55%, 80%**
```
Hour 0 ─────────────────────────────────────► Hour 16
│ │ │
START 55% (8.8h) 80% (12.8h) 100%
│ │ │
threshold1 threshold2 breach
"55% elapsed" "80% elapsed" "BREACHED"
⏳ ⚠️ ⏰
```
**Result:**
- ✅ Job names don't hardcode percentages
- ✅ Messages show actual configured thresholds
- ✅ Cancellation works consistently
- ✅ No edge cases or race conditions

# Dynamic Working Hours Configuration
## Overview
Working hours for TAT (Turn Around Time) calculations are now **dynamically configurable** through the admin settings interface. Admins can change these settings at any time, and the changes will be reflected in all future TAT calculations.
---
## What's Configurable
### **Working Hours Settings:**
| Setting | Description | Default | Example |
|---------|-------------|---------|---------|
| `WORK_START_HOUR` | Working day starts at (hour) | 9 | 8 (8:00 AM) |
| `WORK_END_HOUR` | Working day ends at (hour) | 18 | 19 (7:00 PM) |
| `WORK_START_DAY` | First working day of week | 1 (Monday) | 1 (Monday) |
| `WORK_END_DAY` | Last working day of week | 5 (Friday) | 6 (Saturday) |
**Days:** 0 = Sunday, 1 = Monday, 2 = Tuesday, ..., 6 = Saturday
---
## How It Works
### **1. Admin Changes Working Hours**
```
Settings → System Configuration → Working Hours
- Work Start Hour: 9:00 → Change to 8:00
- Work End Hour: 18:00 → Change to 20:00
✅ Save
```
### **2. Backend Updates Database**
```sql
UPDATE admin_configurations
SET config_value = '8'
WHERE config_key = 'WORK_START_HOUR';
UPDATE admin_configurations
SET config_value = '20'
WHERE config_key = 'WORK_END_HOUR';
```
### **3. Cache is Cleared Automatically**
```typescript
// In admin.controller.ts
clearConfigCache(); // Clear general config cache
clearWorkingHoursCache(); // Clear TAT working hours cache
```
### **4. Next TAT Calculation Uses New Values**
```typescript
// TAT calculation loads fresh values
await loadWorkingHoursCache();
// → Reads: startHour=8, endHour=20 from database
// Applies new working hours
if (hour >= 8 && hour < 20) {
// This hour counts as working time ✅
}
```
---
## Cache Management
### **Working Hours Cache:**
**Cache Duration:** 5 minutes (shorter than holidays since it's more critical)
**Why Cache?**
- Performance: Avoids repeated database queries
- Speed: TAT calculations can happen hundreds of times per hour
- Efficiency: Reading from memory is ~1000x faster than DB query
**Cache Lifecycle:**
```
1. First TAT Calculation:
→ loadWorkingHoursCache() called
→ Database query: SELECT config_value WHERE config_key IN (...)
→ Store in memory: workingHoursCache = { startHour: 9, endHour: 18, ... }
→ Set expiry: now + 5 minutes
2. Next 5 Minutes (Cache Valid):
→ All TAT calculations use cached values
→ No database queries ✅ FAST
3. After 5 Minutes (Cache Expired):
→ Next TAT calculation reloads from database
→ New cache created with 5-minute expiry
4. Admin Updates Config:
→ clearWorkingHoursCache() called immediately
→ Cache invalidated
→ Next calculation loads fresh values ✅
```
---
## Example Scenarios
### **Scenario 1: Extend Working Hours**
**Before:**
```
Working Hours: 9:00 AM - 6:00 PM (9 hours/day)
```
**Admin Changes To:**
```
Working Hours: 8:00 AM - 8:00 PM (12 hours/day)
```
**Impact on TAT:**
```
Request: STANDARD Priority, 24 working hours
Created: Monday 9:00 AM
OLD Calculation (9 hours/day):
Monday 9 AM - 6 PM = 9 hours (15h remaining)
Tuesday 9 AM - 6 PM = 9 hours (6h remaining)
Wednesday 9 AM - 3 PM = 6 hours (0h remaining)
Deadline: Wednesday 3:00 PM
NEW Calculation (12 hours/day):
Monday 9 AM - 8 PM = 11 hours (13h remaining)
Tuesday 8 AM - 8 PM = 12 hours (1h remaining)
Wednesday 8 AM - 9 AM = 1 hour (0h remaining)
Deadline: Wednesday 9:00 AM ✅ FASTER!
```
---
### **Scenario 2: Include Saturday as Working Day**
**Before:**
```
Working Days: Monday - Friday (1-5)
```
**Admin Changes To:**
```
Working Days: Monday - Saturday (1-6)
```
**Impact on TAT:**
```
Request: STANDARD Priority, 16 working hours
Created: Friday 2:00 PM
OLD Calculation (Mon-Fri only):
Friday 2 PM - 6 PM = 4 hours (12h remaining)
Saturday-Sunday = SKIPPED
Monday 9 AM - 6 PM = 9 hours (3h remaining)
Tuesday 9 AM - 12 PM = 3 hours (0h remaining)
Deadline: Tuesday 12:00 PM
NEW Calculation (Mon-Sat):
Friday 2 PM - 6 PM = 4 hours (12h remaining)
Saturday 9 AM - 6 PM = 9 hours (3h remaining) ✅ Saturday counts!
Sunday = SKIPPED
Monday 9 AM - 12 PM = 3 hours (0h remaining)
Deadline: Monday 12:00 PM ✅ EARLIER!
```
---
### **Scenario 3: Reduce Working Hours (After-Hours Emergency)**
**Before:**
```
Working Hours: 9:00 AM - 6:00 PM
```
**Admin Changes To:**
```
Working Hours: 9:00 AM - 10:00 PM (extended for emergency)
```
**Impact:**
```
Request created at 7:00 PM (after old hours but within new hours)
OLD System:
7:00 PM → Not working time
First working hour: Tomorrow 9:00 AM
TAT starts counting from tomorrow ❌
NEW System:
7:00 PM → Still working time! ✅
TAT starts counting immediately
Faster response for urgent requests ✅
```
---
## Implementation Details
### **Configuration Reader Service**
```typescript
// Re_Backend/src/services/configReader.service.ts
export async function getWorkingHours(): Promise<{ startHour: number; endHour: number }> {
const startHour = await getConfigNumber('WORK_START_HOUR', 9);
const endHour = await getConfigNumber('WORK_END_HOUR', 18);
return { startHour, endHour };
}
```
### **TAT Time Utils (Working Hours Cache)**
```typescript
// Re_Backend/src/utils/tatTimeUtils.ts
let workingHoursCache: WorkingHoursConfig | null = null;
let workingHoursCacheExpiry: Date | null = null;
async function loadWorkingHoursCache(): Promise<void> {
// Check if cache is still valid
if (workingHoursCacheExpiry && new Date() < workingHoursCacheExpiry) {
return; // Use cached values
}
// Load from database
const { getWorkingHours, getConfigNumber } = await import('../services/configReader.service');
const hours = await getWorkingHours();
const startDay = await getConfigNumber('WORK_START_DAY', 1);
const endDay = await getConfigNumber('WORK_END_DAY', 5);
// Store in cache
workingHoursCache = {
startHour: hours.startHour,
endHour: hours.endHour,
startDay: startDay,
endDay: endDay
};
// Set 5-minute expiry
workingHoursCacheExpiry = dayjs().add(5, 'minute').toDate();
console.log(`[TAT Utils] Loaded working hours: ${hours.startHour}:00-${hours.endHour}:00`);
}
function isWorkingTime(date: Dayjs): boolean {
// Use cached working hours (with fallback to defaults)
const config = workingHoursCache || {
startHour: 9,
endHour: 18,
startDay: 1,
endDay: 5
};
const day = date.day();
const hour = date.hour();
// Check based on configured values
if (day < config.startDay || day > config.endDay) return false;
if (hour < config.startHour || hour >= config.endHour) return false;
if (isHoliday(date)) return false;
return true;
}
```
### **Admin Controller (Cache Invalidation)**
```typescript
// Re_Backend/src/controllers/admin.controller.ts
export const updateConfiguration = async (req: Request, res: Response): Promise<void> => {
// ... update database ...
// Clear config cache
clearConfigCache();
// If working hours config was updated, also clear TAT cache
const workingHoursKeys = ['WORK_START_HOUR', 'WORK_END_HOUR', 'WORK_START_DAY', 'WORK_END_DAY'];
if (workingHoursKeys.includes(configKey)) {
clearWorkingHoursCache(); // ✅ Immediate cache clear
logger.info(`Working hours config '${configKey}' updated - cache cleared`);
}
res.json({ success: true });
};
```
---
## Priority Behavior
### **STANDARD Priority**
✅ **Uses configured working hours**
- Respects `WORK_START_HOUR` and `WORK_END_HOUR`
- Respects `WORK_START_DAY` and `WORK_END_DAY`
- Excludes holidays
**Example:**
```
Config: 9:00 AM - 6:00 PM, Monday-Friday
TAT: 16 working hours
→ Only hours between 9 AM - 6 PM on Mon-Fri count
→ Weekends and holidays are skipped
```
### **EXPRESS Priority**
❌ **Ignores working hours configuration**
- Counts ALL 24 hours per day
- Counts ALL 7 days per week
- Counts holidays
**Example:**
```
Config: 9:00 AM - 6:00 PM (ignored)
TAT: 16 hours
→ Simply add 16 hours to start time
→ No exclusions
```
---
## Testing Scenarios
### **Test 1: Change Working Hours, Create Request**
```bash
# 1. Check current working hours
curl http://localhost:5000/api/v1/admin/configurations \
| grep WORK_START_HOUR
# → Returns: "configValue": "9"
# 2. Update working hours to start at 8:00 AM
curl -X PUT http://localhost:5000/api/v1/admin/configurations/WORK_START_HOUR \
-H "Authorization: Bearer TOKEN" \
-d '{"configValue": "8"}'
# → Response: "Configuration updated successfully"
# 3. Check logs
# → Should see: "Working hours configuration 'WORK_START_HOUR' updated - cache cleared"
# 4. Create new STANDARD request
curl -X POST http://localhost:5000/api/v1/workflows \
-d '{"priority": "STANDARD", "tatHours": 16}'
# 5. Check TAT calculation logs
# → Should see: "Loaded working hours: 8:00-18:00" ✅
# → Deadline calculation uses new hours ✅
```
### **Test 2: Verify Cache Expiry**
```bash
# 1. Create request (loads working hours into cache)
# → Cache expires in 5 minutes
# 2. Wait 6 minutes
# 3. Create another request
# → Should see log: "Loaded working hours: ..." (cache reloaded)
# 4. Create third request immediately
# → No log (uses cached values)
```
### **Test 3: Extend to 6-Day Week**
```bash
# 1. Update end day to Saturday
curl -X PUT http://localhost:5000/api/v1/admin/configurations/WORK_END_DAY \
-d '{"configValue": "6"}'
# 2. Create request on Friday afternoon
# → Deadline should include Saturday ✅
# → Sunday still excluded ✅
```
---
## Database Configuration
### **Configuration Keys:**
```sql
SELECT config_key, config_value, display_name
FROM admin_configurations
WHERE config_key IN (
'WORK_START_HOUR',
'WORK_END_HOUR',
'WORK_START_DAY',
'WORK_END_DAY'
);
-- Example results:
-- WORK_START_HOUR | 9 | Work Start Hour
-- WORK_END_HOUR | 18 | Work End Hour
-- WORK_START_DAY | 1 | Work Start Day (Monday)
-- WORK_END_DAY | 5 | Work End Day (Friday)
```
### **Update Example:**
```sql
-- Change working hours to 8 AM - 8 PM
UPDATE admin_configurations
SET config_value = '8', updated_at = NOW()
WHERE config_key = 'WORK_START_HOUR';
UPDATE admin_configurations
SET config_value = '20', updated_at = NOW()
WHERE config_key = 'WORK_END_HOUR';
-- Include Saturday as working day
UPDATE admin_configurations
SET config_value = '6', updated_at = NOW()
WHERE config_key = 'WORK_END_DAY';
```
---
## Logging Examples
### **Configuration Update:**
```
[Admin] Working hours configuration 'WORK_START_HOUR' updated - cache cleared
[ConfigReader] Configuration cache cleared
[TAT Utils] Working hours cache cleared
```
### **TAT Calculation:**
```
[TAT Utils] Loaded working hours: 8:00-20:00, Days: 1-6
[TAT Scheduler] Using STANDARD mode - excludes holidays, weekends, non-working hours
[TAT Scheduler] Calculating TAT milestones for request REQ-2025-001
[TAT Scheduler] Priority: STANDARD, TAT Hours: 16
[TAT Scheduler] Start: 2025-11-05 09:00
[TAT Scheduler] Threshold 1 (55%): 2025-11-05 17:48 (using 8-20 working hours)
[TAT Scheduler] Threshold 2 (80%): 2025-11-06 10:48
[TAT Scheduler] Breach (100%): 2025-11-06 15:00
```
---
## Migration from Hardcoded Values
### **Before (Hardcoded):**
```typescript
// ❌ Hardcoded in code
const WORK_START_HOUR = 9;
const WORK_END_HOUR = 18;
const WORK_START_DAY = 1;
const WORK_END_DAY = 5;
// To change: Need code update + deployment
```
### **After (Dynamic):**
```typescript
// ✅ Read from database
const config = await getWorkingHours();
// config = { startHour: 9, endHour: 18 }
// To change: Just update in admin UI
// No code changes needed ✅
// No deployment needed ✅
```
---
## Benefits
### **1. Flexibility**
- ✅ Change working hours anytime without code changes
- ✅ No deployment needed
- ✅ Takes effect within 5 minutes
### **2. Global Organizations**
- ✅ Adjust for different time zones
- ✅ Support 24/5 or 24/6 operations
- ✅ Extended hours for urgent periods
### **3. Seasonal Adjustments**
- ✅ Extend hours during busy seasons
- ✅ Reduce hours during slow periods
- ✅ Special hours for events
### **4. Performance**
- ✅ Cache prevents repeated DB queries
- ✅ Fast lookups (memory vs database)
- ✅ Auto-refresh every 5 minutes
### **5. Consistency**
- ✅ All TAT calculations use same values
- ✅ Immediate cache invalidation on update
- ✅ Fallback to defaults if DB unavailable
---
## Summary
| Aspect | Details |
|--------|---------|

# Holiday Handling & EXPRESS Mode TAT Calculation
## Overview
The TAT (Turn Around Time) system now supports:
1. **Holiday Exclusions** - Configured holidays are excluded from STANDARD priority TAT calculations
2. **EXPRESS Mode** - EXPRESS priority requests use 24/7 calculation (no exclusions)
---
## How It Works
### **STANDARD Priority (Default)**
**Calculation:**
- ✅ Excludes weekends (Saturday, Sunday)
- ✅ Excludes non-working hours (9 AM - 6 PM by default)
- ✅ **Excludes holidays configured in Admin Settings**
**Example:**
```
TAT = 16 working hours
Start: Monday 2:00 PM
Calculation:
Monday 2:00 PM - 6:00 PM = 4 hours (remaining: 12h)
Tuesday 9:00 AM - 6:00 PM = 9 hours (remaining: 3h)
Wednesday 9:00 AM - 12:00 PM = 3 hours (remaining: 0h)
If Wednesday is a HOLIDAY → Skip to Thursday:
Wednesday (HOLIDAY) = 0 hours (skipped)
Thursday 9:00 AM - 12:00 PM = 3 hours (remaining: 0h)
Final deadline: Thursday 12:00 PM ✅
```
---
### **EXPRESS Priority**
**Calculation:**
- ✅ Counts ALL hours (24/7)
- ✅ **No weekend exclusion**
- ✅ **No non-working hours exclusion**
- ✅ **No holiday exclusion**
**Example:**
```
TAT = 16 hours
Start: Monday 2:00 PM
Calculation:
Simply add 16 hours:
Monday 2:00 PM + 16 hours = Tuesday 6:00 AM
Final deadline: Tuesday 6:00 AM ✅
(Even if Tuesday is a holiday, it still counts)
```
---
## Holiday Configuration Flow
### **1. Admin Adds Holiday**
```
Settings Page → Holiday Manager → Add Holiday
Name: "Christmas Day"
Date: 2025-12-25
Type: Public Holiday
✅ Save
```
### **2. Holiday Stored in Database**
```sql
INSERT INTO holidays (holiday_date, holiday_name, holiday_type, is_active)
VALUES ('2025-12-25', 'Christmas Day', 'PUBLIC_HOLIDAY', true);
```
### **3. Holiday Cache Updated**
```typescript
// Holidays are cached in memory for 6 hours
await loadHolidaysCache();
// → holidaysCache = Set(['2025-12-25', '2025-01-01', ...])
```
### **4. TAT Calculation Uses Holiday Cache**
```typescript
// When scheduling TAT jobs
if (priority === 'STANDARD') {
// Working hours calculation - checks holidays
const threshold1 = await addWorkingHours(start, hours * 0.55);
// → If date is in holidaysCache, it's skipped ✅
} else {
// EXPRESS: 24/7 calculation - ignores holidays
const threshold1 = addCalendarHours(start, hours * 0.55);
// → Adds hours directly, no checks ✅
}
```

### **Function: `addWorkingHours()` (STANDARD Mode)**
```typescript
export async function addWorkingHours(start: Date, hoursToAdd: number): Promise<Dayjs> {
let current = dayjs(start);
// Load holidays from database (cached)
await loadHolidaysCache();
let remaining = hoursToAdd;
while (remaining > 0) {
current = current.add(1, 'hour');
// Check if current hour is working time
if (isWorkingTime(current)) { // ✅ Checks holidays here
remaining -= 1;
}
}
return current;
}
function isWorkingTime(date: Dayjs): boolean {
// Check weekend
if (date.day() === 0 || date.day() === 6) return false;
// Check working hours
if (date.hour() < 9 || date.hour() >= 18) return false;
// Check if holiday ✅
if (isHoliday(date)) return false;
return true;
}
function isHoliday(date: Dayjs): boolean {
const dateStr = date.format('YYYY-MM-DD');
return holidaysCache.has(dateStr); // ✅ Checks cached holidays
}
```
---
### **Function: `addCalendarHours()` (EXPRESS Mode)**
```typescript
export function addCalendarHours(start: Date, hoursToAdd: number): Dayjs {
// Simple addition - no checks ✅
return dayjs(start).add(hoursToAdd, 'hour');
}
```
---
## TAT Scheduler Integration
### **Updated Method Signature:**
```typescript
async scheduleTatJobs(
requestId: string,
levelId: string,
approverId: string,
tatDurationHours: number,
startTime?: Date,
priority: Priority = Priority.STANDARD // ✅ New parameter
): Promise<void>
```
### **Priority-Based Calculation:**
```typescript
const isExpress = priority === Priority.EXPRESS;
if (isExpress) {
// EXPRESS: 24/7 calculation
threshold1Time = addCalendarHours(now, hours * 0.55).toDate();
threshold2Time = addCalendarHours(now, hours * 0.80).toDate();
breachTime = addCalendarHours(now, hours).toDate();
logger.info('Using EXPRESS mode (24/7) - no holiday/weekend exclusions');
} else {
// STANDARD: Working hours, exclude holidays
const t1 = await addWorkingHours(now, hours * 0.55);
const t2 = await addWorkingHours(now, hours * 0.80);
const tBreach = await addWorkingHours(now, hours);
threshold1Time = t1.toDate();
threshold2Time = t2.toDate();
breachTime = tBreach.toDate();
logger.info('Using STANDARD mode - excludes holidays, weekends, non-working hours');
}
```
---
## Example Scenarios
### **Scenario 1: STANDARD with Holiday**
```
Request Details:
- Priority: STANDARD
- TAT: 16 working hours
- Start: Monday 2:00 PM
- Holiday: Wednesday (Christmas)
Calculation:
Monday 2:00 PM - 6:00 PM = 4 hours (12h remaining)
Tuesday 9:00 AM - 6:00 PM = 9 hours (3h remaining)
Wednesday (HOLIDAY) = SKIPPED ✅
Thursday 9:00 AM - 12:00 PM = 3 hours (0h remaining)
TAT Milestones:
- Threshold 1 (55%): Tuesday 4:40 PM (8.8 working hours)
- Threshold 2 (80%): Thursday 10:48 AM (12.8 working hours)
- Breach (100%): Thursday 12:00 PM (16 working hours)
```
---
### **Scenario 2: EXPRESS with Holiday**
```
Request Details:
- Priority: EXPRESS
- TAT: 16 hours
- Start: Monday 2:00 PM
- Holiday: Wednesday (Christmas) - IGNORED ✅
Calculation:
Monday 2:00 PM + 16 hours = Tuesday 6:00 AM
TAT Milestones:
- Threshold 1 (55%): Monday 10:48 PM (8.8 hours)
- Threshold 2 (80%): Tuesday 2:48 AM (12.8 hours)
- Breach (100%): Tuesday 6:00 AM (16 hours)
Note: Even though Wednesday is a holiday, EXPRESS doesn't care ✅
```
---
### **Scenario 3: Multiple Holidays**
```
Request Details:
- Priority: STANDARD
- TAT: 40 working hours
- Start: Friday 10:00 AM
- Holidays: Monday (New Year), Tuesday (Day After)
Calculation:
Friday 10:00 AM - 6:00 PM = 8 hours (32h remaining)
Saturday-Sunday = SKIPPED (weekend)
Monday (HOLIDAY) = SKIPPED ✅
Tuesday (HOLIDAY) = SKIPPED ✅
Wednesday 9:00 AM - 6:00 PM = 9 hours (23h remaining)
Thursday 9:00 AM - 6:00 PM = 9 hours (14h remaining)
Friday 9:00 AM - 6:00 PM = 9 hours (5h remaining)
Monday 9:00 AM - 2:00 PM = 5 hours (0h remaining)
Final deadline: Next Monday 2:00 PM ✅
(Skipped 2 weekends + 2 holidays)
```
---
## Holiday Cache Management
### **Cache Lifecycle:**
```
1. Server Startup
→ initializeHolidaysCache() called
→ Holidays loaded into memory
2. Cache Valid for 6 Hours
→ holidaysCacheExpiry = now + 6 hours
→ Subsequent calls use cached data (fast)
3. Cache Expires After 6 Hours
→ Next TAT calculation reloads cache from DB
→ New cache expires in 6 hours
4. Manual Cache Refresh (Optional)
→ Admin adds/updates holiday
→ Call initializeHolidaysCache() to refresh immediately
```
### **Cache Performance:**
```
Without Cache:
- Every TAT calculation → DB query → SLOW ❌
- 100 requests/hour → 100 DB queries
With Cache:
- Load once per 6 hours → DB query → FAST ✅
- 100 requests/hour → 0 DB queries (use cache)
- Cache refresh: Every 6 hours or on-demand
```
---
## Priority Detection in Services
### **Workflow Service (Submission):**
```typescript
// When submitting workflow
const workflowPriority = (updated as any).priority || 'STANDARD';
await tatSchedulerService.scheduleTatJobs(
requestId,
levelId,
approverId,
tatHours,
now,
workflowPriority // ✅ Pass priority
);
```
### **Approval Service (Next Level):**
```typescript
// When moving to next approval level
const workflowPriority = (wf as any)?.priority || 'STANDARD';
await tatSchedulerService.scheduleTatJobs(
requestId,
nextLevelId,
nextApproverId,
tatHours,
now,
workflowPriority // ✅ Pass priority
);
```
---
## Database Schema
### **Holidays Table:**
```sql
CREATE TABLE holidays (
holiday_id UUID PRIMARY KEY,
holiday_date DATE NOT NULL,
holiday_name VARCHAR(255) NOT NULL,
holiday_type VARCHAR(50),
description TEXT,
is_active BOOLEAN DEFAULT true,
created_at TIMESTAMP DEFAULT NOW(),
updated_at TIMESTAMP DEFAULT NOW()
);
-- Example data
INSERT INTO holidays (holiday_date, holiday_name, holiday_type)
VALUES
('2025-12-25', 'Christmas Day', 'PUBLIC_HOLIDAY'),
('2025-01-01', 'New Year''s Day', 'PUBLIC_HOLIDAY'),
('2025-07-04', 'Independence Day', 'PUBLIC_HOLIDAY');
```
### **Workflow Request Priority:**
```sql
-- WorkflowRequest table already has priority field
SELECT request_id, priority, tat_hours
FROM workflow_requests
WHERE priority = 'EXPRESS'; -- 24/7 calculation
-- OR
WHERE priority = 'STANDARD'; -- Working hours + holiday exclusion
```
---
## Testing Scenarios
### **Test 1: Add Holiday, Create STANDARD Request**
```bash
# 1. Add holiday for tomorrow
curl -X POST http://localhost:5000/api/v1/admin/holidays \
-H "Authorization: Bearer TOKEN" \
-d '{
"holidayDate": "2025-11-06",
"holidayName": "Test Holiday",
"holidayType": "PUBLIC_HOLIDAY"
}'
# 2. Create STANDARD request with 24h TAT
curl -X POST http://localhost:5000/api/v1/workflows \
-d '{
"priority": "STANDARD",
"tatHours": 24
}'
# 3. Check scheduled TAT jobs in logs
# → Should show deadline skipping the holiday ✅
```
### **Test 2: Same Holiday, EXPRESS Request**
```bash
# 1. Holiday still exists (tomorrow)
# 2. Create EXPRESS request with 24h TAT
curl -X POST http://localhost:5000/api/v1/workflows \
-d '{
"priority": "EXPRESS",
"tatHours": 24
}'
# 3. Check scheduled TAT jobs in logs
# → Should show deadline NOT skipping the holiday ✅
# → Exactly 24 hours from now (includes holiday)
```
### **Test 3: Verify Holiday Exclusion**
```bash
# Create request on Friday afternoon
# With 16 working hours TAT
# Should skip weekend and land on Monday/Tuesday
# If Monday is a holiday:
# → STANDARD: Should land on Tuesday ✅
# → EXPRESS: Should land on Sunday ✅
```
---
## Logging Examples

## Summary
### **What Changed:**
1. ✅ Added `addCalendarHours()` for EXPRESS mode (24/7 calculation)
2. ✅ Updated `addWorkingHours()` to check holidays from admin settings
3. ✅ Added `priority` parameter to `scheduleTatJobs()`
4. ✅ Updated workflow/approval services to pass priority
5. ✅ Holiday cache for performance (6-hour expiry)
### **How Holidays Are Used:**
| Priority | Calculation Method | Holidays | Weekends | Non-Working Hours |
|----------|-------------------|----------|----------|-------------------|
| **STANDARD** | Working hours only | ✅ Excluded | ✅ Excluded | ✅ Excluded |
| **EXPRESS** | 24/7 calendar hours | ❌ Counted | ❌ Counted | ❌ Counted |
### **Benefits:**
1. ✅ **Accurate TAT for STANDARD** - Respects holidays, no false breaches
2. ✅ **Fast EXPRESS** - True 24/7 calculation for urgent requests
3. ✅ **Centralized Holiday Management** - Admin can add/edit holidays
4. ✅ **Performance** - Holiday cache prevents repeated DB queries
5. ✅ **Flexible** - Priority can be changed per request
---
## Files Modified
1. `Re_Backend/src/utils/tatTimeUtils.ts` - Added `addCalendarHours()` for EXPRESS mode
2. `Re_Backend/src/services/tatScheduler.service.ts` - Added priority parameter and logic
3. `Re_Backend/src/services/workflow.service.ts` - Pass priority when scheduling TAT
4. `Re_Backend/src/services/approval.service.ts` - Pass priority for next level TAT

## Configuration Keys
| Config Key | Default | Description |
|------------|---------|-------------|
| `WORK_START_HOUR` | 9 | Working hours start (STANDARD mode only) |
| `WORK_END_HOUR` | 18 | Working hours end (STANDARD mode only) |
| `WORK_START_DAY` | 1 | Monday (STANDARD mode only) |
| `WORK_END_DAY` | 5 | Friday (STANDARD mode only) |
**Note:** EXPRESS mode ignores all these configurations and uses 24/7 calculation.

# 🚀 Migration Quick Reference
## Daily Development Workflow
### Starting Development (Auto-runs Migrations)
```bash
npm run dev
```
✅ **This will automatically run all new migrations before starting the server!**
### Run Migrations Only
```bash
npm run migrate
```
## Adding a New Migration (3 Steps)
### 1️⃣ Create Migration File
Location: `src/migrations/YYYYMMDD-description.ts`
```typescript
import { QueryInterface, DataTypes } from 'sequelize';
export async function up(queryInterface: QueryInterface): Promise<void> {
await queryInterface.addColumn('table_name', 'column_name', {
type: DataTypes.STRING,
allowNull: true,
});
console.log('✅ Migration completed');
}
export async function down(queryInterface: QueryInterface): Promise<void> {
await queryInterface.removeColumn('table_name', 'column_name');
console.log('✅ Rollback completed');
}
```
### 2️⃣ Register in `src/scripts/migrate.ts`
```typescript
// Add import at top
import * as m15 from '../migrations/YYYYMMDD-description';
// Add execution in run() function
await (m15 as any).up(sequelize.getQueryInterface());
```
### 3️⃣ Test
```bash
npm run migrate
```
## Common Operations
### Add Column
```typescript
await queryInterface.addColumn('table', 'column', {
type: DataTypes.STRING(100),
allowNull: false,
defaultValue: 'value'
});
```
### Add Foreign Key
```typescript
await queryInterface.addColumn('table', 'foreign_id', {
type: DataTypes.UUID,
references: { model: 'other_table', key: 'id' },
onUpdate: 'CASCADE',
onDelete: 'SET NULL'
});
```
### Add Index
```typescript
await queryInterface.addIndex('table', ['column'], {
name: 'idx_table_column'
});
```
### Create Table
```typescript
await queryInterface.createTable('new_table', {
id: {
type: DataTypes.UUID,
defaultValue: DataTypes.UUIDV4,
primaryKey: true
},
name: DataTypes.STRING(100),
created_at: DataTypes.DATE,
updated_at: DataTypes.DATE
});
```
## What's New ✨
### Latest Migration: Skip Approver Functionality
- **File**: `20251105-add-skip-fields-to-approval-levels.ts`
- **Added Fields**:
- `is_skipped` - Boolean flag
- `skipped_at` - Timestamp
- `skipped_by` - User reference
- `skip_reason` - Text explanation
- **Index**: Partial index on `is_skipped = TRUE`
## Troubleshooting
| Issue | Solution |
|-------|----------|
| Migration fails | Check console error, fix migration file, re-run |
| Column exists error | Migration partially ran - add idempotent checks |
| Server won't start | Fix migration first, it blocks startup |

# Migration Workflow Guide
## Overview
This project uses a TypeScript-based migration system for database schema changes. All migrations are automatically executed when you start the development server.
## 🚀 Quick Start
### Running Development Server with Migrations
```bash
npm run dev
```
This command will:
1. ✅ Run all pending migrations automatically
2. 🚀 Start the development server with hot reload
### Running Migrations Only
```bash
npm run migrate
```
Use this when you only want to apply migrations without starting the server.
## 📝 Creating New Migrations
### Step 1: Create Migration File
Create a new TypeScript file in `src/migrations/` with the naming pattern:
```
YYYYMMDD-descriptive-name.ts
```
Example: `20251105-add-new-field.ts`
### Step 2: Migration Template
```typescript
import { QueryInterface, DataTypes } from 'sequelize';
/**
* Migration: Brief description
* Purpose: Detailed explanation
* Date: YYYY-MM-DD
*/
export async function up(queryInterface: QueryInterface): Promise<void> {
// Add your forward migration logic here
await queryInterface.addColumn('table_name', 'column_name', {
type: DataTypes.STRING,
allowNull: true,
});
console.log('✅ Migration description completed');
}
export async function down(queryInterface: QueryInterface): Promise<void> {
// Add your rollback logic here
await queryInterface.removeColumn('table_name', 'column_name');
console.log('✅ Migration rolled back');
}
```
### Step 3: Register Migration
Add your new migration to `src/scripts/migrate.ts`:
```typescript
// 1. Import at the top
import * as m15 from '../migrations/20251105-add-new-field';
// 2. Execute in the run() function
await (m15 as any).up(sequelize.getQueryInterface());
```
### Step 4: Test
```bash
npm run migrate
```
## 📋 Current Migrations
The following migrations are configured and will run in order:
1. `2025103001-create-workflow-requests` - Core workflow requests table
2. `2025103002-create-approval-levels` - Approval hierarchy structure
3. `2025103003-create-participants` - Workflow participants
4. `2025103004-create-documents` - Document attachments
5. `20251031_01_create_subscriptions` - User subscriptions
6. `20251031_02_create_activities` - Activity tracking
7. `20251031_03_create_work_notes` - Work notes/comments
8. `20251031_04_create_work_note_attachments` - Note attachments
9. `20251104-add-tat-alert-fields` - TAT alert fields
10. `20251104-create-tat-alerts` - TAT alerts table
11. `20251104-create-kpi-views` - KPI database views
12. `20251104-create-holidays` - Holiday calendar
13. `20251104-create-admin-config` - Admin configurations
14. `20251105-add-skip-fields-to-approval-levels` - Skip approver functionality
## 🔄 Migration Safety Features
### Idempotent Migrations
All migrations should be **idempotent** (safe to run multiple times). Use checks like:
```typescript
// Check if column exists before adding
const tableDescription = await queryInterface.describeTable('table_name');
if (!tableDescription.column_name) {
await queryInterface.addColumn(/* ... */);
}
// Check if table exists before creating
const tables = await queryInterface.showAllTables();
if (!tables.includes('table_name')) {
await queryInterface.createTable(/* ... */);
}
```
### Error Handling
Migrations automatically:
- ✅ Stop on first error
- ❌ Exit with error code 1 on failure
- 📝 Log detailed error messages
- 🔄 Prevent server startup if migrations fail
## 🛠️ Common Migration Operations
### Adding a Column
```typescript
await queryInterface.addColumn('table_name', 'new_column', {
type: DataTypes.STRING(100),
allowNull: false,
defaultValue: 'default_value',
comment: 'Column description'
});
```
### Adding Foreign Key
```typescript
await queryInterface.addColumn('table_name', 'foreign_key_id', {
type: DataTypes.UUID,
allowNull: true,
references: {
model: 'referenced_table',
key: 'id'
},
onUpdate: 'CASCADE',
onDelete: 'SET NULL'
});
```
### Creating Index
```typescript
await queryInterface.addIndex('table_name', ['column_name'], {
name: 'idx_table_column',
unique: false
});
// Partial index with WHERE clause
await queryInterface.addIndex('table_name', ['status'], {
name: 'idx_table_active',
where: {
is_active: true
}
});
```
### Creating Table
```typescript
await queryInterface.createTable('new_table', {
id: {
type: DataTypes.UUID,
defaultValue: DataTypes.UUIDV4,
primaryKey: true
},
name: {
type: DataTypes.STRING(100),
allowNull: false
},
created_at: {
type: DataTypes.DATE,
allowNull: false,
defaultValue: DataTypes.NOW
},
updated_at: {
type: DataTypes.DATE,
allowNull: false,
defaultValue: DataTypes.NOW
}
});
```
### Modifying Column
```typescript
await queryInterface.changeColumn('table_name', 'column_name', {
type: DataTypes.STRING(200), // Changed from 100
allowNull: true // Changed from false
});
```
### Dropping Column
```typescript
await queryInterface.removeColumn('table_name', 'old_column');
```
### Raw SQL Queries
```typescript
await queryInterface.sequelize.query(`
CREATE OR REPLACE VIEW view_name AS
SELECT * FROM table_name WHERE condition
`);
```
## 📊 Database Structure Reference
Always refer to `backend_structure.txt` for the authoritative database structure including:
- All tables and their columns
- Data types and constraints
- Relationships and foreign keys
- Enum values
- Indexes
## 🚨 Troubleshooting
### Migration Fails with "Column Already Exists"
- The migration might have partially run
- Add idempotent checks or manually rollback the failed migration
### Server Won't Start After Migration
- Check the migration error in console
- Fix the migration file
- Run `npm run migrate` to retry
### Need to Rollback a Migration
```bash
# Manual rollback (requires implementing down() function)
ts-node src/scripts/rollback.ts
```
## 🎯 Best Practices
1. **Always test migrations** on development database first
2. **Write rollback logic** in `down()` function
3. **Use descriptive names** for migrations
4. **Add comments** explaining the purpose
5. **Keep migrations small** - one logical change per file
6. **Never modify** existing migration files after they run in production
7. **Use transactions** for complex multi-step migrations
8. **Backup production** before running new migrations
## 📝 Migration Checklist
Before running migrations in production:
- [ ] Tested on local development database
- [ ] Verified rollback functionality works
- [ ] Checked for data loss scenarios
- [ ] Reviewed index impact on performance
- [ ] Confirmed migration is idempotent
- [ ] Updated `backend_structure.txt` documentation
- [ ] Added migration to version control
- [ ] Registered in `migrate.ts`

# Quick Fix: Settings Not Editable Issue
## 🔴 Problem
Settings showing as "not editable" in the frontend.
## 🎯 Root Cause
**Field Mapping Issue:** Database uses `is_editable` (snake_case) but frontend expects `isEditable` (camelCase).
## ✅ Solution Applied
### **1. Fixed Admin Controller** ✅
Added field mapping from snake_case to camelCase:
```typescript
// Re_Backend/src/controllers/admin.controller.ts
const configurations = rawConfigurations.map(config => ({
configId: config.config_id, // ✅ Mapped
isEditable: config.is_editable, // ✅ Mapped
isSensitive: config.is_sensitive, // ✅ Mapped
requiresRestart: config.requires_restart, // ✅ Mapped
// ... all other fields
}));
```
### **2. Database Fix Required**
**Option A: Delete and Re-seed** (Recommended if no custom configs)
```sql
-- Connect to your database
DELETE FROM admin_configurations;
-- Restart backend - auto-seeding will run
-- Check logs for: "✅ Default configurations seeded (18 settings)"
```
**Option B: Fix Existing Records** (If you have custom values)
```sql
-- Update existing records to add missing fields
UPDATE admin_configurations
SET
is_sensitive = COALESCE(is_sensitive, false),
requires_restart = COALESCE(requires_restart, false),
is_editable = COALESCE(is_editable, true)
WHERE is_sensitive IS NULL
OR requires_restart IS NULL
OR is_editable IS NULL;
-- Set requires_restart = true for settings that need it
UPDATE admin_configurations
SET requires_restart = true
WHERE config_key IN (
'WORK_START_HOUR',
'WORK_END_HOUR',
'MAX_FILE_SIZE_MB',
'ALLOWED_FILE_TYPES'
);
```
---
## 🚀 Step-by-Step Fix
### **Step 1: Stop Backend**
```bash
# Press Ctrl+C to stop the server
```
### **Step 2: Clear Configurations** (if any exist)
```sql
-- Connect to PostgreSQL
psql -U postgres -d re_workflow
-- Check if configurations exist
SELECT COUNT(*) FROM admin_configurations;
-- If count > 0, delete them
DELETE FROM admin_configurations;
-- Verify
SELECT COUNT(*) FROM admin_configurations;
-- Should show: 0
```
### **Step 3: Restart Backend** (Auto-seeds)
```bash
cd Re_Backend
npm run dev
```
### **Step 4: Verify Seeding in Logs**
Look for:
```
⚙️ System configurations initialized
✅ Default configurations seeded successfully (18 settings across 7 categories)
```
### **Step 5: Test in Frontend**
1. Login as Admin user
2. Go to **Settings → System Configuration**
3. You should see **7 category tabs**
4. Click any tab (e.g., "TAT SETTINGS")
5. All settings should now have:
- ✅ Editable input fields
- ✅ **Save** button enabled
- ✅ **Reset to Default** button
---
## 🧪 Verify Configuration Loaded Correctly
**Test API Endpoint:**
```bash
# Get all configurations
curl http://localhost:5000/api/v1/admin/configurations \
-H "Authorization: Bearer YOUR_JWT_TOKEN"
```
**Expected Response:**
```json
{
"success": true,
"data": [
{
"configId": "uuid...",
"configKey": "DEFAULT_TAT_EXPRESS_HOURS",
"configCategory": "TAT_SETTINGS",
"configValue": "24",
"valueType": "NUMBER",
"displayName": "Default TAT for Express Priority",
"isEditable": true, // ✅ Should be true
"isSensitive": false,
"validationRules": {"min": 1, "max": 168},
"uiComponent": "number",
"sortOrder": 1,
"requiresRestart": false
},
// ... 17 more configurations
],
"count": 18
}
```
**Check the `isEditable` field - should be `true` for all!**
---
## 🐛 Common Issues & Solutions
### Issue 1: "Configurations already exist. Skipping seed."
**Cause:** Old configurations in database
**Fix:** Delete them and restart backend
### Issue 2: Settings show as gray/disabled
**Cause:** `is_editable = false` in database
**Fix:** Run SQL update to set all to `true`
### Issue 3: "Configuration not found or not editable" error when saving
**Cause:** Backend can't find the config or `is_editable = false`
**Fix:** Verify database has correct values
### Issue 4: Empty settings page
**Cause:** No configurations in database
**Fix:** Check backend logs for seeding errors, run seed manually
---
## 📊 Expected Database State
After successful seeding, your `admin_configurations` table should have:
| Count | Category | All Editable? |
|-------|----------|---------------|
| 6 | TAT_SETTINGS | ✅ Yes |
| 3 | DOCUMENT_POLICY | ✅ Yes |
| 2 | AI_CONFIGURATION | ✅ Yes |
| 3 | NOTIFICATION_RULES | ✅ Yes |
| 4 | DASHBOARD_LAYOUT | ✅ Yes |
| 3 | WORKFLOW_SHARING | ✅ Yes |
| 2 | WORKFLOW_LIMITS | ✅ Yes |
| **18 Total** | **7 Categories** | **✅ All Editable** |
Query to verify:
```sql
SELECT

## 🛡️ Permissions
| Action | Who Can Do It |
|--------|---------------|
| Skip Approver | ✅ INITIATOR, ✅ APPROVER |
| Add Approver | ✅ INITIATOR, ✅ APPROVER |
| View Skip Reason | ✅ All participants |
---
## ⚠️ Limitations
| Limitation | Reason |
|------------|--------|
| Cannot skip approved levels | Data integrity |
| Cannot skip rejected levels | Already closed |
| Cannot skip already skipped levels | Already handled |
| Cannot skip future levels | Not yet active |
| Cannot add before completed levels | Would break workflow state |
| Must provide valid TAT (1-720h) | Business rules |
---
## 📊 Dashboard Impact
### **Skipped Approvers in Reports:**
```sql
-- Count skipped approvers
SELECT COUNT(*)
FROM approval_levels
WHERE is_skipped = TRUE;
-- Find requests with skipped levels
SELECT r.request_number, al.level_number, al.approver_name, al.skip_reason
FROM workflow_requests r
JOIN approval_levels al ON r.request_id = al.request_id
WHERE al.is_skipped = TRUE;
```
### **KPIs Affected:**
- **Avg Approval Time** - Skipped levels excluded from calculation
- **Approver Response Rate** - Skipped marked separately
- **Workflow Bottlenecks** - Identify frequently skipped approvers
---
## 🔍 Troubleshooting
### **"Cannot skip approver - level is already APPROVED"**
- The level has already been approved
- You cannot skip completed levels
### **"Cannot skip future approval levels"**
- You're trying to skip a level that hasn't been reached yet
- Only current level can be skipped
### **"Cannot add approver at level X. Minimum allowed level is Y"**
- You're trying to add before a completed level
- Must add after all approved/rejected/skipped levels
### **"User is already a participant in this request"**
- The user is already an approver, initiator, or spectator
- Cannot add same user twice
---

# Skip Approver & Dynamic Approver Addition
## Overview
This feature allows initiators and approvers to manage approval workflows dynamically when approvers are unavailable or additional approval is needed.
### **Key Features:**
1. **Skip Approver** - Skip non-responding approvers and move to next level
2. **Add Approver at Specific Level** - Insert new approver at any position
3. **Automatic Level Shifting** - Existing approvers are automatically renumbered
4. **Smart Validation** - Cannot modify completed levels (approved/rejected/skipped)
5. **TAT Management** - New approvers get their own TAT, jobs scheduled automatically
---
## Use Cases
### **Use Case 1: Approver on Leave**
**Scenario:**
```
Level 1: Sarah (Approved) ✅
Level 2: Mike (Pending) ⏳ ← On vacation, not responding
Level 3: Lisa (Waiting) ⏸️
```
**Solution:**
```
Initiator clicks "Skip This Approver" on Level 2
→ Mike is marked as SKIPPED
→ Level 3 (Lisa) becomes active
→ Lisa receives notification
→ TAT jobs cancelled for Mike, scheduled for Lisa
```
**Result:**
```
Level 1: Sarah (Approved) ✅
Level 2: Mike (Skipped) ⏭️ ← Skipped
Level 3: Lisa (In Review) ⏳ ← Now active
```
---
### **Use Case 2: Add Additional Reviewer**
**Scenario:**
```
Level 1: Sarah (Approved) ✅
Level 2: Mike (In Review) ⏳
Level 3: Lisa (Waiting) ⏸️
```
**Need:** Add Finance Manager (John) between Mike and Lisa
**Solution:**
```
Click "Add Approver"
→ Email: john@example.com
→ TAT: 48 hours
→ Level: 3 (between Mike and Lisa)
→ Submit
```
**Result:**
```
Level 1: Sarah (Approved) ✅
Level 2: Mike (In Review) ⏳ ← Still at level 2
Level 3: John (Waiting) ⏸️ ← NEW! Inserted here
Level 4: Lisa (Waiting) ⏸️ ← Shifted from 3 to 4
```
---
### **Use Case 3: Replace Skipped Approver**
**Scenario:**
```
Level 1: Sarah (Approved) ✅
Level 2: Mike (Skipped) ⏭️
Level 3: Lisa (In Review) ⏳
```
**Need:** Add replacement for Mike at level 2
**Solution:**
```
Click "Add Approver"
→ Email: john@example.com
→ TAT: 24 hours
→ Level: 2 (Mike's old position)
→ Submit
```
**Result:**
```
Level 1: Sarah (Approved) ✅
Level 2: John (Waiting) ⏸️ ← NEW! Inserted at level 2
Level 3: Mike (Skipped) ⏭️ ← Shifted from 2 to 3
Level 4: Lisa (In Review) ⏳ ← Shifted from 3 to 4
```
---
## Database Schema
### **New Fields in `approval_levels` Table:**
```sql
-- Migration: add_is_skipped_to_approval_levels.sql
ALTER TABLE approval_levels
ADD COLUMN is_skipped BOOLEAN DEFAULT FALSE,
ADD COLUMN skipped_at TIMESTAMP,
ADD COLUMN skipped_by UUID REFERENCES users(user_id),
ADD COLUMN skip_reason TEXT;
```
### **Status Enum Update:**
Already includes `SKIPPED` status:
```sql
status ENUM('PENDING', 'IN_PROGRESS', 'APPROVED', 'REJECTED', 'SKIPPED')
```
### **Example Data:**
```sql
-- Level 2 was skipped
SELECT
level_number,
approver_name,
status,
is_skipped,
skipped_at,
skip_reason
FROM approval_levels
WHERE request_id = 'xxx';
-- Results:
-- 1 | Sarah | APPROVED | FALSE | NULL | NULL
-- 2 | Mike | SKIPPED | TRUE | 2025-11-05 | On vacation
-- 3 | Lisa | PENDING | FALSE | NULL | NULL
```
---
## API Endpoints
### **1. Skip Approver**
**Endpoint:**
```
POST /api/v1/workflows/:id/approvals/:levelId/skip
```
**Request Body:**
```json
{
"reason": "Approver on vacation - deadline approaching"
}
```
**Response:**
```json
{
"success": true,
"message": "Approver skipped successfully",
"data": {
"levelId": "...",
"levelNumber": 2,
"status": "SKIPPED",
"skippedAt": "2025-11-05T10:30:00Z"
}
}
```
**Logic:**
1. ✅ Mark level as `SKIPPED`
2. ✅ Cancel TAT jobs for skipped level
3. ✅ Activate next level (move to level+1)
4. ✅ Schedule TAT jobs for next level
5. ✅ Notify next approver
6. ✅ Log activity
**Validation:**
- ❌ Cannot skip already approved/rejected/skipped levels
- ❌ Cannot skip future levels (only current level)
- ✅ Only INITIATOR or APPROVER can skip
---
### **2. Add Approver at Specific Level**
**Endpoint:**
```
POST /api/v1/workflows/:id/approvers/at-level
```
**Request Body:**
```json
{
"email": "john@example.com",
"tatHours": 48,
"level": 3
}
```
**Response:**
```json
{
"success": true,
"message": "Approver added successfully",
"data": {
"levelId": "...",
"levelNumber": 3,
"approverName": "John Doe",
"tatHours": 48,
"status": "PENDING"
}
}
```
**Logic:**
1. ✅ Find user by email
2. ✅ Validate target level (must be after completed levels)
3. ✅ Shift existing levels at and after target level (+1)
4. ✅ Create new approval level at target position
5. ✅ Add as participant (APPROVER type)
6. ✅ If new level is current level, schedule TAT jobs
7. ✅ Notify new approver
8. ✅ Log activity
**Validation:**
- ❌ User must exist in system
- ❌ User cannot be existing participant
- ❌ Level must be after completed levels (approved/rejected/skipped)
- ✅ Automatic level shifting for existing approvers
---
## Level Shifting Logic
### **Example: Add at Level 3**
**Before:**
```
Level 1: Sarah (Approved) ✅
Level 2: Mike (In Review) ⏳
Level 3: Lisa (Waiting) ⏸️
Level 4: Tom (Waiting) ⏸️
```
**Action:**
```
Add John at Level 3 with 48h TAT
```
**Backend Processing:**
```typescript
// Step 1: Get levels to shift (levelNumber >= 3)
levelsToShift = [Lisa (Level 3), Tom (Level 4)]
// Step 2: Shift each level
Lisa: Level 3 → Level 4
Tom: Level 4 → Level 5
// Step 3: Insert new approver
John: Create at Level 3
// Step 4: Update workflow.totalLevels
totalLevels: 4 → 5
```
**After:**
```
Level 1: Sarah (Approved) ✅
Level 2: Mike (In Review) ⏳
Level 3: John (Waiting) ⏸️ ← NEW!
Level 4: Lisa (Waiting) ⏸️ ← Shifted from 3
Level 5: Tom (Waiting) ⏸️ ← Shifted from 4
```
---
## Frontend Implementation
### **AddApproverModal Enhancements:**
**New Props:**
```typescript
interface AddApproverModalProps {
open: boolean;
onClose: () => void;
onConfirm: (email: string, tatHours: number, level: number) => Promise<void>;
currentLevels?: ApprovalLevelInfo[]; // ✅ NEW!
}
interface ApprovalLevelInfo {
levelNumber: number;
approverName: string;
status: string;
tatHours: number;
}
```
**UI Components:**
1. **Current Levels Display** - Shows all existing levels with status badges
2. **Level Selector** - Dropdown with available levels (after completed)
3. **TAT Hours Input** - Number input for TAT (1-720 hours)
4. **Email Search** - Existing @ mention search
**Example Modal:**
```
┌─────────────────────────────────────────────────┐
│ Add Approver │
├─────────────────────────────────────────────────┤
│ Current Approval Levels │
│ ┌─────────────────────────────────────────────┐ │
│ │ [1] Sarah 50h TAT [✓] approved │ │
│ │ [2] Mike 24h TAT [⏳] pending │ │
│ │ [3] Lisa 36h TAT [⏸] waiting │ │
│ └─────────────────────────────────────────────┘ │
│ │
│ Approval Level * │
│ [Select: Level 2 (will shift existing Level 2)] │
│ │
│ TAT (Turn Around Time) * │
│ [48] hours │
│ │
│ Email Address * │
│ [@john or john@example.com] │
│ │
│ [Cancel] [Add at Level 2] │
└─────────────────────────────────────────────────┘
```
---
### **RequestDetail Skip Button:**
Added to Workflow tab for each pending/in-review level:
```tsx

{(isActive || step.status === 'pending') && !isCompleted && !isRejected && (
<Button
variant="outline"
size="sm"
className="w-full border-orange-300 text-orange-700 hover:bg-orange-50"
onClick={() => {
const reason = prompt('Provide reason for skipping:');
if (reason !== null) {
handleSkipApprover(step.levelId, reason);
}
}}
>
<AlertCircle className="w-4 h-4 mr-2" />
Skip This Approver
</Button>
)}
```
---

4. Get levels to shift: [Lisa (Level 3)]
5. Shift Lisa:
- Level 3 → Level 4
- levelName: "Level 4"
6. Create new Level 3:
- levelNumber: 3
- approverId: John's userId
- approverEmail: john@example.com
- tatHours: 48
- status: PENDING (not current level)
7. Update workflow.totalLevels: 3 → 4
8. Add John to participants (APPROVER type)
9. Notify John
10. Log activity: "John added as approver at Level 3 with TAT of 48 hours"
```
**Final State:**
```
Request: REQ-2025-001
Current Level: 2
Level 1: Sarah (APPROVED) ✅
Level 2: Mike (IN_PROGRESS) ⏳ ← Still working
Level 3: John (PENDING) ⏸️ ← NEW! Will review after Mike
Level 4: Lisa (PENDING) ⏸️ ← Shifted from 3 to 4
```
---
### **Example 3: Complex Scenario - Skip and Add**
**Initial State:**
```
Level 1: Sarah (APPROVED) ✅
Level 2: Mike (APPROVED) ✅
Level 3: David (IN_PROGRESS) ⏳ ← Taking too long
Level 4: Lisa (PENDING) ⏸️
Level 5: Tom (PENDING) ⏸️
```
**Action 1: Skip David**
```
Result:
Level 1: Sarah (APPROVED) ✅
Level 2: Mike (APPROVED) ✅
Level 3: David (SKIPPED) ⏭️
Level 4: Lisa (IN_PROGRESS) ⏳ ← Now active
Level 5: Tom (PENDING) ⏸️
```
**Action 2: Add John at Level 4 (before Tom)**
```
Result:
Level 1: Sarah (APPROVED) ✅
Level 2: Mike (APPROVED) ✅
Level 3: David (SKIPPED) ⏭️
Level 4: Lisa (IN_PROGRESS) ⏳
Level 5: John (PENDING) ⏸️ ← NEW!
Level 6: Tom (PENDING) ⏸️ ← Shifted
```
---
## UI/UX
### **RequestDetail - Workflow Tab:**
**Skip Button Visibility:**
- ✅ Shows for levels with status: `pending` or `in-review`
- ❌ Hidden for `approved`, `rejected`, `skipped`, or `waiting`
- ✅ Orange/amber styling to indicate caution
- ✅ Requires reason via prompt
**Button Appearance:**
```tsx
┌───────────────────────────────────────────┐
│ Level 2: Mike (In Review) │
│ TAT: 24h • Elapsed: 15h │
│ │
│ [⚠ Skip This Approver] │
│ Skip if approver is unavailable... │
└───────────────────────────────────────────┘
```
---
### **AddApproverModal - Enhanced UI:**
**Sections:**
1. **Current Levels** - Scrollable list showing all existing levels with status
2. **Level Selector** - Dropdown with available levels (grayed out completed levels)
3. **TAT Input** - Hours input with validation (1-720)
4. **Email Search** - @ mention search (existing)
**Features:**
- ✅ Auto-selects first available level
- ✅ Shows which existing level will be shifted
- ✅ Visual indicators for completed vs pending levels
- ✅ Prevents selecting invalid levels
- ✅ Real-time validation
---

## TAT Handling
### **Skip Approver:**
```typescript
// Skipped level's TAT jobs are cancelled
await tatSchedulerService.cancelTatJobs(requestId, skippedLevelId);
// Next level's TAT jobs are scheduled
await tatSchedulerService.scheduleTatJobs(
requestId,
nextLevelId,
nextApproverId,
nextLevelTatHours,
now,
workflowPriority
);
```
### **Add Approver:**
```typescript
// If new approver is at current level, schedule TAT immediately
if (newLevel === currentLevel) {
await tatSchedulerService.scheduleTatJobs(
requestId,
newLevelId,
newApproverId,
tatHours,
now,
workflowPriority
);
}
// Otherwise, jobs will be scheduled when level becomes active
```
---

# ✅ Smart Migration System Complete
## 🎯 What You Asked For
> "Every time if I do npm run dev, migrations are running right? If that already exist then skip, if it is new tables then do migrations"
**✅ DONE!** Your migration system is now intelligent and efficient.
---
## 🧠 How It Works Now
### Smart Migration Tracking
The system now includes:
1. **🗃️ Migrations Tracking Table**
- Automatically created on first run
- Stores which migrations have been executed
- Prevents duplicate execution
2. **⏭️ Smart Detection**
- Checks which migrations already ran
- Only executes **new/pending** migrations
- Skips already-completed ones
3. **🛡️ Idempotent Migrations**
- Safe to run multiple times
- Checks if tables/columns exist before creating
- No errors if schema already matches
---
## 📊 What Happens When You Run `npm run dev`
### First Time (Fresh Database)
```
📦 Database connected
✅ Created migrations tracking table
🔄 Running 14 pending migration(s)...
⏳ Running: 2025103001-create-workflow-requests
✅ Created workflow_requests table
✅ Completed: 2025103001-create-workflow-requests
⏳ Running: 2025103002-create-approval-levels
✅ Created approval_levels table
✅ Completed: 2025103002-create-approval-levels
... (all 14 migrations run)
✅ Successfully applied 14 migration(s)
📊 Total migrations: 14
🚀 Server running on port 5000
```
### Second Time (All Migrations Already Run)
```
📦 Database connected
✅ All migrations are up-to-date (no new migrations to run)
🚀 Server running on port 5000
```
**⚡ Instant startup! No migration overhead!**
### When You Add a New Migration
```
📦 Database connected
🔄 Running 1 pending migration(s)...
⏳ Running: 20251106-new-feature
✅ Added new column
✅ Completed: 20251106-new-feature
✅ Successfully applied 1 migration(s)
📊 Total migrations: 15
🚀 Server running on port 5000
```
**Only the NEW migration runs!**
---
## 🔧 Technical Implementation
### 1. Migration Tracking Database
Automatically created table:
```sql
CREATE TABLE migrations (
id SERIAL PRIMARY KEY,
name VARCHAR(255) NOT NULL UNIQUE,
executed_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
)
```
Tracks:
- ✅ Which migrations have been executed
- ✅ When they were executed
- ✅ Prevents duplicate execution via UNIQUE constraint
### 2. Smart Migration Runner
**File**: `src/scripts/migrate.ts`
**Key Features**:
```typescript
// 1. Check what's already been run
const executedMigrations = await getExecutedMigrations();
// 2. Find only new/pending migrations
const pendingMigrations = migrations.filter(
m => !executedMigrations.includes(m.name)
);
// 3. Skip if nothing to do
if (pendingMigrations.length === 0) {
console.log('✅ All migrations up-to-date');
return;
}
// 4. Run only pending migrations
for (const migration of pendingMigrations) {
await migration.module.up(queryInterface);
await markMigrationExecuted(migration.name);
}
```
### 3. Idempotent Migrations
**Example**: `20251105-add-skip-fields-to-approval-levels.ts`
**Checks before acting**:
```typescript
// Check if table exists
const tables = await queryInterface.showAllTables();
if (!tables.includes('approval_levels')) {
return; // Skip if table doesn't exist
}
// Check if column exists
const tableDescription = await queryInterface.describeTable('approval_levels');
if (!tableDescription.is_skipped) {
await queryInterface.addColumn(/* ... */);
}
// Check if index exists
const indexes = await queryInterface.showIndex('approval_levels');
const indexExists = indexes.some(idx => idx.name === 'idx_name');
if (!indexExists) {
await queryInterface.addIndex(/* ... */);
}
```
**Safe to run multiple times!**
---
## 🚀 Usage Examples
### Daily Development Workflow
```bash
# Morning - start work
npm run dev
# ✅ All up-to-date - server starts immediately
# After pulling new code with migration
git pull origin main
npm run dev
# 🔄 Runs only the new migration
# ✅ Server starts
```
### Adding a New Migration
```bash
# 1. Create migration file
# src/migrations/20251106-add-user-preferences.ts
# 2. Register in migrate.ts
# (add import and execution)
# 3. Test
npm run dev
# 🔄 Runs only your new migration
# 4. Run again to verify idempotency
npm run dev
# ✅ All up-to-date (doesn't run again)
```
### Manual Migration Run
```bash
npm run migrate
# Same smart behavior, without starting server
```
---

## 📝 Adding New Migrations
### Template for Idempotent Migrations
```typescript
import { QueryInterface, DataTypes } from 'sequelize';
export async function up(queryInterface: QueryInterface): Promise<void> {
// 1. Check if table exists (for new tables)
const tables = await queryInterface.showAllTables();
if (!tables.includes('my_table')) {
await queryInterface.createTable('my_table', {/* ... */});
console.log(' ✅ Created my_table');
return;
}
// 2. Check if column exists (for new columns)
const tableDesc = await queryInterface.describeTable('existing_table');
if (!tableDesc.new_column) {
await queryInterface.addColumn('existing_table', 'new_column', {
type: DataTypes.STRING
});
console.log(' ✅ Added new_column');
}
// 3. Check if index exists (for new indexes)
try {
const indexes: any[] = await queryInterface.showIndex('my_table') as any[];
const indexExists = Array.isArray(indexes) &&
indexes.some((idx: any) => idx.name === 'idx_name');
if (!indexExists) {
await queryInterface.addIndex('my_table', ['column'], {
name: 'idx_name'
});
console.log(' ✅ Added idx_name');
}
} catch (error) {
console.log(' ℹ️ Index handling skipped');
}
console.log('✅ Migration completed');
}
export async function down(queryInterface: QueryInterface): Promise<void> {
// Rollback logic
await queryInterface.removeColumn('my_table', 'new_column');
console.log('✅ Rollback completed');
}
```
### Steps to Add New Migration
1. **Create File**: `src/migrations/YYYYMMDD-description.ts`
2. **Write Migration**: Use idempotent template above
3. **Register**: Add to `src/scripts/migrate.ts`:
```typescript
import * as m15 from '../migrations/20251106-description';
const migrations: Migration[] = [
// ... existing ...
{ name: '20251106-description', module: m15 },
];
```
4. **Test**: Run `npm run dev` - only new migration executes
5. **Verify**: Run `npm run dev` again - should skip (already executed)
---
## 🧪 Testing the System
### Test 1: First Run
```bash
# Drop database (if testing)
# Then run:
npm run dev
# Expected: All 14 migrations run
# migrations table created
# Server starts
```
### Test 2: Second Run
```bash
npm run dev
# Expected: "All migrations up-to-date"
# No migrations run
# Instant server start
```
### Test 3: New Migration
```bash
# Add migration #15
npm run dev
# Expected: Only migration #15 runs
# Shows "Running 1 pending migration"
# Server starts
```
### Test 4: Verify Tracking
```bash
# In PostgreSQL:
SELECT * FROM migrations ORDER BY id;
# Should show all executed migrations with timestamps
```
---
## 🔍 Monitoring Migration Status
### Check Database Directly
```sql
-- See all executed migrations
SELECT id, name, executed_at
FROM migrations
ORDER BY id;
-- Count migrations
SELECT COUNT(*) as total_migrations FROM migrations;
-- Latest migration
SELECT name, executed_at
FROM migrations
ORDER BY id DESC
LIMIT 1;
```
### Check via Application
```bash
# Run migration script
npm run migrate
# Output shows:
# - Total migrations in code
# - Already executed count
# - Pending count
```
---
## 🚨 Troubleshooting
### Issue: "Table already exists"
**Solution**: This shouldn't happen now! But if it does:
- Migration might not be idempotent
- Add table existence check
- See idempotent template above
### Issue: "Column already exists"
**Solution**: Add column existence check:
```typescript
const tableDesc = await queryInterface.describeTable('table');
if (!tableDesc.column_name) {
await queryInterface.addColumn(/* ... */);
}
```
### Issue: Migration runs every time
**Cause**: Not being marked as executed
**Check**:
```sql
SELECT * FROM migrations WHERE name = 'migration-name';
```
If missing, the marking step failed.
### Issue: Need to rerun a migration
**Solution**:
```sql
-- Remove from tracking (use with caution!)
DELETE FROM migrations WHERE name = 'migration-name';
-- Then run
npm run migrate
```
---
## 📊 System Architecture
```
npm run dev
↓
migrate.ts runs
↓
Check: migrations table exists?
↓ No → Create it
↓ Yes → Continue
↓
Query: SELECT * FROM migrations
↓
Compare: Code migrations vs DB migrations
↓
Pending = Code - DB
↓
If pending = 0
↓ → "All up-to-date" → Start server
↓
If pending > 0
↓
For each pending migration:
↓
Run migration.up()
↓
INSERT INTO migrations
↓
Mark as complete
↓
All done → Start server
```
