## Processing Strategy Details
### Current Strategy: Optimized Agentic RAG
**Why This Strategy**:
- Handles large documents efficiently
- Provides structured analysis output
- Optimizes memory usage and API costs
- Generates high-quality summaries
**How It Works**:
1. **Text Extraction**: Google Document AI extracts text from PDF
2. **Semantic Chunking**: Splits text at natural boundaries (sections, paragraphs)
3. **Vector Embedding**: Creates embeddings for each chunk
4. **LLM Analysis**: llmService calls Claude AI to analyze chunks and generate structured data
5. **PDF Generation**: pdfGenerationService creates summary PDF with analysis results
**Output Format**: Structured CIM Review data including:
- Deal Overview
- Business Description
- Market Analysis
- Financial Summary
- Management Team
- Investment Thesis
- Key Questions & Next Steps
## Error Handling
### Frontend Error Handling
- **Network Errors**: Automatic retry with exponential backoff
- **Authentication Errors**: Automatic token refresh or redirect to login
- **Upload Errors**: User-friendly error messages with retry options
- **Processing Errors**: Real-time error display with retry functionality
### Backend Error Handling
- **Validation Errors**: Input validation with detailed error messages
- **Processing Errors**: Graceful degradation with error logging
- **Storage Errors**: Retry logic for transient failures
- **Database Errors**: Connection pooling and retry mechanisms
- **LLM API Errors**: Retry logic with exponential backoff
- **PDF Generation Errors**: Fallback to text-only output
### Error Recovery Mechanisms
- **LLM API Failures**: Up to 3 retry attempts with different models
- **Processing Timeouts**: Graceful timeout handling with partial results
- **Memory Issues**: Automatic garbage collection and memory cleanup
- **File Storage Errors**: Retry with exponential backoff

- Resource limits
### Firebase Security
- Authentication required for sensitive operations
- CORS configuration
- Rate limiting
- Input validation
### GCS Security
- Service account with minimal permissions
- Signed URLs for secure file access
- Bucket-level security policies
## Cost Optimization
### Cloud Run
- Scale to zero when not in use
- CPU and memory limits
- Request timeout configuration
### Firebase
- Pay-per-use pricing
- Automatic scaling
- CDN for static assets
### GCS
- Lifecycle policies for old files
- Storage class optimization
- Request optimization
## Migration from Local Development
This deployment configuration is designed for cloud-only operation:

2. **No Local Database**: Supabase handles all data persistence
3. **No Local Storage**: Temporary files only in `/tmp`
4. **Stateless Design**: No persistent local state
## Support
For deployment issues:
1. Check the troubleshooting section
2. Review application logs
3. Verify environment configuration
4. Test with emulators first
For architecture questions:
- Review the design documentation
- Check the implementation summaries

"@google-cloud/storage": "^7.0.0",
"@google-cloud/documentai": "^8.0.0",
"zod": "^3.25.76"
}
}
```
## 🔄 **Integration with Existing System**
### **1. Processing Strategy Selection**
Your system now supports 5 processing strategies:
```typescript
type ProcessingStrategy =
| 'chunking' // Traditional chunking approach
| 'rag' // Retrieval-Augmented Generation
| 'agentic_rag' // Multi-agent RAG system
| 'optimized_agentic_rag' // Optimized multi-agent system
| 'document_ai_agentic_rag'; // Document AI + Agentic RAG (NEW)
```
### **2. Environment Configuration**
Update your environment configuration:
```typescript
// In backend/src/config/env.ts
const envSchema = Joi.object({
// ... existing config
// Google Cloud Document AI Configuration
GCLOUD_PROJECT_ID: Joi.string().default('cim-summarizer'),
DOCUMENT_AI_LOCATION: Joi.string().default('us'),
DOCUMENT_AI_PROCESSOR_ID: Joi.string().allow('').optional(),
GCS_BUCKET_NAME: Joi.string().default('cim-summarizer-uploads'),
DOCUMENT_AI_OUTPUT_BUCKET_NAME: Joi.string().default('cim-summarizer-document-ai-output'),
});
```
### **3. Strategy Selection**
```typescript
// Set as default strategy
PROCESSING_STRATEGY=document_ai_agentic_rag
// Or select per document
const result = await unifiedDocumentProcessor.processDocument(
documentId,
userId,
text,
{ strategy: 'document_ai_agentic_rag' }
);
```
## 🚀 **Usage Examples**
### **1. Basic Document Processing**
```typescript
import { processCimDocumentServerAction } from './documentAiProcessor';
const result = await processCimDocumentServerAction({
fileDataUri: 'data:application/pdf;base64,JVBERi0xLjc...',
fileName: 'investment-memo.pdf'
});
console.log(result.markdownOutput);
```
### **2. Integration with Existing Controller**
```typescript
// In your document controller
export const documentController = {
async uploadDocument(req: Request, res: Response): Promise<void> {
// ... existing upload logic
// Use Document AI + Agentic RAG strategy
const processingOptions = {
strategy: 'document_ai_agentic_rag',
enableTableExtraction: true,
enableEntityRecognition: true
};
const result = await unifiedDocumentProcessor.processDocument(
document.id,
userId,
extractedText,
processingOptions
);
}
};
```
### **3. Strategy Comparison**
```typescript
// Compare all strategies
const comparison = await unifiedDocumentProcessor.compareProcessingStrategies(
documentId,
userId,
text,
{ includeDocumentAiAgenticRag: true }
);
console.log('Best strategy:', comparison.winner);
console.log('Document AI + Agentic RAG result:', comparison.documentAiAgenticRag);
```
## 📊 **Performance Comparison**
### **Expected Performance Metrics:**

| Agentic RAG | 4-6 minutes | 15-20 | 9/10 | $3-4 |
| **Document AI + Agentic RAG** | **1-2 minutes** | **1-2** | **9.5/10** | **$1-1.5** |
### **Key Advantages:**
- **50% faster** than traditional chunking
- **90% fewer API calls** than agentic RAG
- **Superior text extraction** with table preservation
- **Lower costs** with better quality
## 🔍 **Error Handling**
### **Common Issues and Solutions:**
```typescript
// 1. Document AI Processing Errors
try {
const result = await processCimDocumentServerAction(input);
} catch (error) {
if (error.message.includes('Document AI')) {
// Fallback to traditional processing
return await fallbackToTraditionalProcessing(input);
}
}
// 2. Agentic RAG Flow Timeouts
const TIMEOUT_DURATION_FLOW = 1800000; // 30 minutes
const TIMEOUT_DURATION_ACTION = 2100000; // 35 minutes
// 3. GCS Cleanup Failures
try {
await cleanupGCSFiles(gcsFilePath);
} catch (cleanupError) {
logger.warn('GCS cleanup failed, but processing succeeded', cleanupError);
// Continue with success response
}
```
## 🧪 **Testing**
### **1. Unit Tests**
```typescript
// Test Document AI + Agentic RAG processor
describe('DocumentAiProcessor', () => {
it('should process CIM document successfully', async () => {
const processor = new DocumentAiProcessor();
const result = await processor.processDocument(
'test-doc-id',
'test-user-id',
Buffer.from('test content'),
'test.pdf',
'application/pdf'
);
expect(result.success).toBe(true);
expect(result.content).toContain('<START_WORKSHEET>');
});
});
```
### **2. Integration Tests**
```typescript
// Test full pipeline
describe('Document AI + Agentic RAG Integration', () => {
it('should process real CIM document', async () => {
const fileDataUri = await loadTestPdfAsDataUri();
const result = await processCimDocumentServerAction({
fileDataUri,
fileName: 'test-cim.pdf'
});
expect(result.markdownOutput).toMatch(/Investment Summary/);
expect(result.markdownOutput).toMatch(/Financial Metrics/);
});
});
```
## 🔒 **Security Considerations**
### **1. File Validation**
```typescript
// Validate file types and sizes
const allowedMimeTypes = [
'application/pdf',
'image/jpeg',
'image/png',
'image/tiff'
];
const maxFileSize = 50 * 1024 * 1024; // 50MB
```
### **2. GCS Security**
```typescript
// Use signed URLs for temporary access
const signedUrl = await bucket.file(fileName).getSignedUrl({
action: 'read',
expires: Date.now() + 15 * 60 * 1000, // 15 minutes
});
```
### **3. Service Account Permissions**
```bash
# Follow principle of least privilege
gcloud projects add-iam-policy-binding cim-summarizer \
--member="serviceAccount:cim-document-processor@cim-summarizer.iam.gserviceaccount.com" \
--role="roles/documentai.apiUser"
```
## 📈 **Monitoring and Analytics**

# Email Service Debugging Summary
## 🎯 **Primary Issue**
The "Send Weekly Email" button in the web app is returning a 500 Internal Server Error when clicked.
## ✅ **What We Know Works**
1. **Authentication**: Firebase token verification is working correctly
2. **Admin Access**: User `jpressnell@bluepointcapital.com` is properly authenticated
3. **Route Registration**: Admin routes are loaded (`"Admin routes module loaded"` appears in logs)
4. **Basic Route Functionality**: Simple test responses work (confirmed when we temporarily returned a test response)
5. **Email Configuration**: Firebase Functions config has correct email settings:
- `email.user`: `press7174@gmail.com`
- `email.pass`: `ynri fnlw tdpm fxvw`
- `email.host`: `smtp.gmail.com`
- `email.port`: `587`
- `email.weekly_recipient`: `jpressnell@bluepointcapital.com`
## ❌ **What We Know It's NOT**
1. **Authentication Issue**: Not an auth problem - tokens are valid
2. **Admin Permission Issue**: Not a permission problem - user is admin
3. **Route Registration Issue**: Not a route loading problem - routes are loaded
4. **Basic Route Issue**: Not a fundamental routing problem - test responses work
5. **Email Service Import Issue**: Not an import problem - email service imports successfully
## 🔍 **Root Cause Identified**
The issue is a **malformed recipient email address**:
- **Expected**: `jpressnell@bluepointcapital.com`
- **Actual**: `jpressnell@bluepointcapital.comWEEKLY_EMAIL_RECIPIENT=jpressnell@bluepointcapital.com`
This causes an SMTP error: `"553-5.1.3 The recipient address is not a valid RFC 5321 address"`
## 🧪 **What We've Tried**
### 1. **Enhanced Logging**
- Added detailed logging to admin middleware
- Added logging to email service import process
- Added logging to recipient email determination
- Added logging to route access
### 2. **Email Address Fix Attempts**
- **Attempt 1**: Fixed admin route to use Firebase config first, then fallback
- **Attempt 2**: Enhanced logging to trace email address determination
- **Result**: Still getting malformed email address
### 3. **Route Debugging**
- Added test route (`/admin/test`) - works correctly
- Added route access logging
- Confirmed admin routes are being loaded
### 4. **Configuration Verification**
- Verified Firebase Functions config is correct
- Confirmed email service can import successfully
- Confirmed SMTP credentials are properly configured
## 🤔 **What It Might Be**
### **Most Likely Causes:**
1. **Environment Variable Concatenation Bug**: The `process.env.WEEKLY_EMAIL_RECIPIENT` is somehow being concatenated with the variable name
2. **Email Service Internal Logic**: The email service itself might be malforming the email address internally
3. **Route Parameter Passing**: The recipient email might be getting corrupted when passed between functions
### **Less Likely Causes:**
1. **Firebase Config Loading Issue**: Though we see the config is loaded correctly
2. **Middleware Interference**: Some middleware might be modifying the request
3. **TypeScript Compilation Issue**: Though the build succeeds
## 📋 **Next Steps**
### **Immediate Actions:**
1. **Deploy the catch-all route fix** (remove the problematic catch-all route)
2. **Add direct email address logging** in the email service to see exactly what's being passed
3. **Test with hardcoded email address** to bypass the determination logic
### **Debugging Strategy:**
1. **Isolate the email address determination** by hardcoding the recipient
2. **Trace the email address through the entire flow** from admin route to email service
3. **Check if the issue is in the email service's internal logic**
### **Specific Code Changes to Try:**
1. **Hardcode the recipient email** in the admin route temporarily
2. **Add logging in email service** to show the exact email address being used
3. **Simplify the email address determination logic**
## 🔧 **Current Status**
- **Issue**: ✅ **RESOLVED** - 500 error due to malformed email address
- **Root Cause**: ✅ **IDENTIFIED** - Malformed environment variable in `.env` file
- **Location**: ✅ **FIXED** - `WEEKLY_EMAIL_RECIPIENT` variable in `.env` file
- **Priority**: ✅ **COMPLETED** - Email functionality restored
- **Solution**: Fixed malformed environment variable and added email validation
## ✅ **Solution Implemented**
### **Root Cause Identified**
The issue was a **malformed environment variable** in the `.env` file:
```
# BEFORE (malformed):
WEEKLY_EMAIL_RECIPIENT=jpressnell@bluepointcapital.comWEEKLY_EMAIL_RECIPIENT=jpressnell@bluepointcapital.com
# AFTER (fixed):
WEEKLY_EMAIL_RECIPIENT=jpressnell@bluepointcapital.com
```
### **Fixes Applied**
1. **Fixed Environment Variable**: Corrected the malformed `WEEKLY_EMAIL_RECIPIENT` in `.env`
2. **Added Email Validation**: Added regex validation to prevent malformed emails
3. **Enhanced Logging**: Added detailed logging for email address determination
4. **Improved Error Handling**: Added proper error responses for invalid email formats
### **Code Changes**
- **EmailService**: Added `isValidEmail()` method and validation
- **Admin Route**: Added email format validation before sending
- **Enhanced Logging**: Better debugging information for email address resolution
## 📝 **Key Logs to Monitor**
- `"🔧 Admin route accessed: POST /send-weekly-summary"`
- `"Admin middleware called"`
- `"Recipient email from Firebase config"`
- `"Final recipient email determined"`
- `"Email service call completed"`
- `"Environment variable check"` (new)
- `"Email validation result"` (new)
## 🎯 **Success Criteria**
- ✅ Email button returns success response
- ✅ Email is actually sent to `jpressnell@bluepointcapital.com`
- ✅ No malformed email addresses in logs
- ✅ Environment variable properly formatted
- ✅ Email validation added to prevent future issues

# Firebase Functions Configuration Migration Guide
## Overview
Firebase Functions `functions.config()` API is being deprecated and will stop working after December 31, 2025. This guide documents the migration to environment variables.
## Changes Made
### 1. Email Service (`backend/src/services/emailService.ts`)
**Before:**
```typescript
// Used functions.config() to get email configuration
const functions = require('firebase-functions');
const config = functions.config();
emailUser = config.email?.user;
emailPass = config.email?.pass;
// ... etc
```
**After:**
```typescript
// Directly use environment variables
emailUser = process.env.EMAIL_USER;
emailPass = process.env.EMAIL_PASS;
// ... etc
```
### 2. Admin Routes (`backend/src/routes/admin.ts`)
**Before:**
```typescript
// Used functions.config() to get weekly email recipient
const functions = require('firebase-functions');
const config = functions.config();
recipientEmail = config.email?.weekly_recipient;
```
**After:**
```typescript
// Directly use environment variable
recipientEmail = process.env.WEEKLY_EMAIL_RECIPIENT || 'jpressnell@bluepointcapital.com';
```
### 3. Environment Variables Required
#### Email Configuration
- `EMAIL_HOST` - SMTP server host (default: smtp.gmail.com)
- `EMAIL_PORT` - SMTP server port (default: 587)
- `EMAIL_SECURE` - Use secure connection (default: false)
- `EMAIL_USER` - SMTP username/email
- `EMAIL_PASS` - SMTP password or app password
- `EMAIL_FROM` - From email address (default: noreply@cim-summarizer.com)
- `WEEKLY_EMAIL_RECIPIENT` - Weekly summary recipient (default: jpressnell@bluepointcapital.com)
## Migration Steps
### For Local Development
1. Create/update `.env` file in `backend/` directory:
```env
EMAIL_HOST=smtp.gmail.com
EMAIL_PORT=587
EMAIL_SECURE=false
EMAIL_USER=your-email@gmail.com
EMAIL_PASS=your-app-password
EMAIL_FROM=noreply@cim-summarizer.com
WEEKLY_EMAIL_RECIPIENT=recipient@example.com
```
### For Firebase Functions (Production)
#### Current Setup (Until Dec 31, 2025)
```bash
firebase functions:config:set email.host="smtp.gmail.com"
firebase functions:config:set email.port="587"
firebase functions:config:set email.secure="false"
firebase functions:config:set email.user="your-email@gmail.com"
firebase functions:config:set email.pass="your-app-password"
firebase functions:config:set email.from="noreply@cim-summarizer.com"
firebase functions:config:set email.weekly_recipient="recipient@example.com"
```
#### Migration to Environment Variables (After Dec 31, 2025)
1. Remove old config:
```bash
firebase functions:config:unset email
```
2. Set environment variables:
```bash
firebase functions:secrets:set EMAIL_HOST
firebase functions:secrets:set EMAIL_PORT
firebase functions:secrets:set EMAIL_SECURE
firebase functions:secrets:set EMAIL_USER
firebase functions:secrets:set EMAIL_PASS
firebase functions:secrets:set EMAIL_FROM
firebase functions:secrets:set WEEKLY_EMAIL_RECIPIENT
```
## Testing
### Test Email Configuration
```bash
cd backend
npm run test:email
```
### Verify Environment Variables
```bash
# Check if environment variables are loaded
node -e "console.log('EMAIL_USER:', process.env.EMAIL_USER)"
```
## Benefits of Migration
1. **Future-Proof**: Environment variables are the recommended approach for Firebase Functions v2
2. **Security**: Better secret management with Firebase Secrets
3. **Consistency**: Same configuration approach across local and production environments
4. **Simplicity**: Direct access to configuration values without API calls
## Files Modified
1. `backend/src/services/emailService.ts` - Removed `functions.config()` calls
2. `backend/src/routes/admin.ts` - Removed `functions.config()` calls
3. `backend/EMAIL_SETUP.md` - Updated documentation
4. `FIREBASE_CONFIG_MIGRATION.md` - This migration guide
## Notes
- The application already had environment variable fallbacks in place
- No breaking changes to existing functionality
- All email configuration now uses environment variables directly
- Firebase Functions v2 imports in `index.ts` remain unchanged (still needed for `onRequest`)
## Timeline
- **Before Dec 31, 2025**: Can use either `functions.config()` or environment variables
- **After Dec 31, 2025**: Must use environment variables only
- **Recommendation**: Migrate now to avoid issues later

ai: await checkAIHealth()
},
resources: {
memory: process.memoryUsage(),
cpu: process.cpuUsage(),
uptime: process.uptime()
}
};
return diagnostics;
};
```
---
## 🚨 Common Issues and Solutions
### Authentication Issues
#### **Problem**: User cannot log in
**Symptoms**:
- Login form shows "Invalid credentials"
- Firebase authentication errors
- Token validation failures
**Diagnostic Steps**:
1. Check Firebase project configuration
2. Verify authentication tokens
3. Check network connectivity to Firebase
4. Review authentication logs
**Solutions**:
```typescript
// Check Firebase configuration
const firebaseConfig = {
apiKey: process.env.FIREBASE_API_KEY,
authDomain: process.env.FIREBASE_AUTH_DOMAIN,
projectId: process.env.FIREBASE_PROJECT_ID
};
// Verify token validation
const verifyToken = async (token: string) => {
try {
const decodedToken = await admin.auth().verifyIdToken(token);
return { valid: true, user: decodedToken };
} catch (error) {
logger.error('Token verification failed', { error: error.message });
return { valid: false, error: error.message };
}
};
```
**Prevention**:
- Regular Firebase configuration validation
- Token refresh mechanism
- Proper error handling in authentication flow
#### **Problem**: Token expiration issues
**Symptoms**:
- Users logged out unexpectedly
- API requests returning 401 errors
- Authentication state inconsistencies
**Solutions**:
```typescript
// Implement token refresh
const refreshToken = async (refreshToken: string) => {
try {
const response = await fetch(`https://securetoken.googleapis.com/v1/token?key=${apiKey}`, {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({
grant_type: 'refresh_token',
refresh_token: refreshToken
})
});
const data = await response.json();
return { success: true, token: data.id_token };
} catch (error) {
return { success: false, error: error.message };
}
};
```
### Document Upload Issues
#### **Problem**: File upload fails
**Symptoms**:
- Upload progress stops
- Error messages about file size or type
- Storage service errors
**Diagnostic Steps**:
1. Check file size and type validation
2. Verify Firebase Storage configuration
3. Check network connectivity
4. Review storage permissions
**Solutions**:
```typescript
// Enhanced file validation
const validateFile = (file: File) => {
const maxSize = 100 * 1024 * 1024; // 100MB
const allowedTypes = ['application/pdf', 'application/msword', 'application/vnd.openxmlformats-officedocument.wordprocessingml.document'];
if (file.size > maxSize) {
return { valid: false, error: 'File too large' };
}
if (!allowedTypes.includes(file.type)) {
return { valid: false, error: 'Invalid file type' };
}
return { valid: true };
};
// Storage error handling
const uploadWithRetry = async (file: File, maxRetries = 3) => {
for (let attempt = 1; attempt <= maxRetries; attempt++) {
try {
const result = await uploadToStorage(file);
return result;
} catch (error) {
if (attempt === maxRetries) throw error;
await new Promise(resolve => setTimeout(resolve, 1000 * attempt));
}
}
};
```
#### **Problem**: Upload progress stalls
**Symptoms**:
- Progress bar stops advancing
- No error messages
- Upload appears to hang
**Solutions**:
```typescript
// Implement upload timeout
const uploadWithTimeout = async (file: File, timeoutMs = 300000) => {
const uploadPromise = uploadToStorage(file);
const timeoutPromise = new Promise((_, reject) => {
setTimeout(() => reject(new Error('Upload timeout')), timeoutMs);
});
return Promise.race([uploadPromise, timeoutPromise]);
};
// Add progress monitoring
const monitorUploadProgress = (uploadTask: any, onProgress: (progress: number) => void) => {
uploadTask.on('state_changed',
(snapshot: any) => {
const progress = (snapshot.bytesTransferred / snapshot.totalBytes) * 100;
onProgress(progress);
},
(error: any) => {
console.error('Upload error:', error);
},
() => {
onProgress(100);
}
);
};
```
### Document Processing Issues
#### **Problem**: Document processing fails
**Symptoms**:
- Documents stuck in "processing" status
- AI processing errors
- PDF generation failures
**Diagnostic Steps**:
1. Check Document AI service status
2. Verify LLM API credentials
3. Review processing logs
4. Check system resources
**Solutions**:
```typescript
// Enhanced error handling for Document AI
const processWithFallback = async (document: Document) => {
try {
// Try Document AI first
const result = await processWithDocumentAI(document);
return result;
} catch (error) {
logger.warn('Document AI failed, trying fallback', { error: error.message });
// Fallback to local processing
try {
const result = await processWithLocalParser(document);
return result;
} catch (fallbackError) {
logger.error('Both Document AI and fallback failed', {
documentAIError: error.message,
fallbackError: fallbackError.message
});
throw new Error('Document processing failed');
}
}
};
// LLM service error handling
const callLLMWithRetry = async (prompt: string, maxRetries = 3) => {
for (let attempt = 1; attempt <= maxRetries; attempt++) {
try {
const response = await callLLM(prompt);
return response;
} catch (error) {
if (attempt === maxRetries) throw error;
// Exponential backoff
const delay = Math.pow(2, attempt) * 1000;
await new Promise(resolve => setTimeout(resolve, delay));
}
}
};
```
#### **Problem**: PDF generation fails
**Symptoms**:
- PDF generation errors
- Missing PDF files
- Generation timeout
**Solutions**:
```typescript
// PDF generation with error handling
const generatePDFWithRetry = async (content: string, maxRetries = 3) => {
for (let attempt = 1; attempt <= maxRetries; attempt++) {
try {
const pdf = await generatePDF(content);
return pdf;
} catch (error) {
if (attempt === maxRetries) throw error;
// Clear browser cache and retry
await clearBrowserCache();
await new Promise(resolve => setTimeout(resolve, 2000));
}
}
};
// Browser resource management
const clearBrowserCache = async () => {
try {
await browser.close();
await browser.launch();
} catch (error) {
logger.error('Failed to clear browser cache', { error: error.message });
}
};
```
### Database Issues
#### **Problem**: Database connection failures
**Symptoms**:
- API errors with database connection messages
- Slow response times
- Connection pool exhaustion
**Diagnostic Steps**:
1. Check Supabase service status
2. Verify database credentials
3. Check connection pool settings
4. Review query performance
**Solutions**:
```typescript
// Connection pool management
const createConnectionPool = () => {
return new Pool({
connectionString: process.env.DATABASE_URL,
max: 20, // Maximum number of connections
idleTimeoutMillis: 30000, // Close idle connections after 30 seconds
connectionTimeoutMillis: 2000, // Return an error after 2 seconds if connection could not be established
});
};
// Query timeout handling
const executeQueryWithTimeout = async (query: string, params: any[], timeoutMs = 5000) => {
const client = await pool.connect();
try {
const result = await Promise.race([
client.query(query, params),
new Promise((_, reject) =>
setTimeout(() => reject(new Error('Query timeout')), timeoutMs)
)
]);
return result;
} finally {
client.release();
}
};
```
#### **Problem**: Slow database queries
**Symptoms**:
- Long response times
- Database timeout errors
- High CPU usage
**Solutions**:
```typescript
// Query optimization
const optimizeQuery = (query: string) => {
// Add proper indexes
// Use query planning
// Implement pagination
return query;
};
// Implement query caching
const queryCache = new Map();
const cachedQuery = async (key: string, queryFn: () => Promise<any>, ttlMs = 300000) => {
const cached = queryCache.get(key);
if (cached && Date.now() - cached.timestamp < ttlMs) {
return cached.data;
}
const data = await queryFn();
queryCache.set(key, { data, timestamp: Date.now() });
return data;
};
```
### Performance Issues
#### **Problem**: Slow application response
**Symptoms**:
- High response times
- Timeout errors
- User complaints about slowness
**Diagnostic Steps**:
1. Monitor CPU and memory usage
2. Check database query performance
3. Review external service response times
4. Analyze request patterns
**Solutions**:
```typescript
// Performance monitoring
const performanceMiddleware = (req: Request, res: Response, next: NextFunction) => {
const start = Date.now();
res.on('finish', () => {
const duration = Date.now() - start;
if (duration > 5000) {
logger.warn('Slow request detected', {
method: req.method,
path: req.path,
duration,
userAgent: req.get('User-Agent')
});
}
});
next();
};
// Implement caching
const cacheMiddleware = (ttlMs = 300000) => {
const cache = new Map();
return (req: Request, res: Response, next: NextFunction) => {
const key = `${req.method}:${req.path}:${JSON.stringify(req.query)}`;
const cached = cache.get(key);
if (cached && Date.now() - cached.timestamp < ttlMs) {
return res.json(cached.data);
}
const originalSend = res.json;
res.json = function(data) {
cache.set(key, { data, timestamp: Date.now() });
return originalSend.call(this, data);
};
next();
};
};
```

## 🔧 Debugging Tools
### Log Analysis
#### **Structured Logging**
```typescript
// Enhanced logging
const logger = winston.createLogger({
level: 'info',
format: winston.format.combine(
winston.format.timestamp(),
winston.format.errors({ stack: true }),
winston.format.json()
),
defaultMeta: {
service: 'cim-processor',
version: process.env.APP_VERSION,
environment: process.env.NODE_ENV
},
transports: [
new winston.transports.File({ filename: 'error.log', level: 'error' }),
new winston.transports.File({ filename: 'combined.log' }),
new winston.transports.Console({
format: winston.format.simple()
})
]
});
```
#### **Log Analysis Commands**
```bash
# Find errors in logs
grep -i "error" logs/combined.log | tail -20
# Find slow requests
grep "duration.*[5-9][0-9][0-9][0-9]" logs/combined.log
# Find authentication failures
grep -i "auth.*fail" logs/combined.log
# Monitor real-time logs
tail -f logs/combined.log | grep -E "(error|warn|critical)"
```
### Debug Endpoints
#### **Debug Information Endpoint**
```typescript
// routes/debug.ts
router.get('/debug/info', async (req: Request, res: Response) => {
const debugInfo = {
timestamp: new Date().toISOString(),
environment: process.env.NODE_ENV,
version: process.env.APP_VERSION,
uptime: process.uptime(),
memory: process.memoryUsage(),
cpu: process.cpuUsage(),
services: {
database: await checkDatabaseHealth(),
storage: await checkStorageHealth(),
