--format pdf,html,json,csv \
--company "My Agency" \
--primary-color "#2563eb" \
--output ./detailed-report \
--verbose

Exclude specific sections from reports

ts-wp-payload-migration analyze \
--exclude-sections executiveSummary,riskAssessment \
--csv-tables content,plugins,tasks
`

$3

1. 🔍 WordPress Discovery: Automatically finds wp-config.php in current directory
2. 🔐 Database Connection: Extracts database credentials from wp-config.php
3. 🌐 Site URL Detection: Determines site URL from WordPress configuration
4. 🗄️ Database Analysis: Connects and analyzes WordPress database content

The tool provides robust error handling with detailed, actionable error messages and comprehensive database connection management:

#### Database Connection Features

- Robust Error Handling: Comprehensive error classification with specific error types (authentication, permission, timeout, network, etc.)
- Safe Property Access: Uses optional chaining (?.) throughout database connection logic to prevent runtime errors
- Enhanced Logging: Detailed logging at multiple levels (verbose, info, warn, error) for troubleshooting
- Connection Pooling: Efficient connection pool management with automatic cleanup
- Read-Only Mode: Enforced read-only database access to prevent accidental data modification during analysis
- Retry Logic: Exponential backoff with jitter for failed connection attempts
- MySQL/MariaDB Compatibility: Full compatibility with both MySQL (5.7+) and MariaDB (10.2+)

#### Error Message Examples

`bash


If wp-config.php is not found

❌ WordPress configuration not found!
Please ensure you're running this command from a WordPress document root directory.

If database connection fails with specific error details

❌ Database connection failed: [authentication] Invalid credentials (code: ER_ACCESS_DENIED_ERROR)
Please check your WordPress database configuration in wp-config.php.

If database host is unreachable

❌ Database connection failed: [network] Host 'localhost' not found (code: ENOTFOUND)
Please verify the database host configuration.

If database permissions are insufficient

❌ Database connection failed: [permission] User 'wp_user' has no access to database 'wordpress_db'
Please check database user permissions.
`

#### Database Connection Logging

The tool provides comprehensive logging for database operations:

`bash


Verbose logging shows detailed connection process


🔌 Establishing database connection
🌐 Parsed connection details: host=localhost, port=3306
🏊 Creating connection pool
✅ Database connection established successfully
🔒 Enforcing read-only mode
📊 Retrieving server version: MySQL 8.0.35
🔤 Character set: utf8mb4
`

#### Connection Pool Management

- Automatic Resource Cleanup: Connections are properly released back to the pool
- Pool Status Monitoring: Real-time tracking of active, idle, and total connections
- Safe Property Access: Uses optional chaining for pool configuration access
- Connection Validation: Ping tests and metadata retrieval before use
- Graceful Degradation: Handles connection failures with detailed error context

`

🔍 Troubleshooting

$3

#### Database Connection Errors

The tool provides detailed error classification and troubleshooting guidance:

`bash


Check database connectivity manually

mysql -h localhost -u wp_user -p wordpress_db

Verify credentials in wp-config.php

cat wp-config.php | grep -E "(DB_NAME|DB_USER|DB_PASSWORD|DB_HOST)"

Test connection with verbose logging

DEBUG=wp-migration:* ts-wp-payload-migration analyze /path/to/wordpress --verbose
`

Common Database Error Types and Solutions:

- Authentication Errors (ER_ACCESS_DENIED_ERROR):
- Verify username and password in wp-config.php
- Check if database user exists and has correct permissions

- Database Not Found (ER_BAD_DB_ERROR):
- Confirm database name in wp-config.php matches actual database
- Verify database exists on the server

- Permission Errors (ER_DBACCESS_DENIED_ERROR):
- Grant appropriate permissions to database user
- Ensure user has SELECT privileges on WordPress tables

- Connection Refused (ECONNREFUSED):
- Check if MySQL/MariaDB service is running
- Verify host and port configuration

- Host Not Found (ENOTFOUND):
- Verify database host address
- Check DNS resolution for remote hosts

- Connection Timeout (ETIMEDOUT):
- Increase connection timeout in configuration
- Check network connectivity to database server

Connection Pool Troubleshooting:

`bash


Monitor connection pool status in logs

ts-wp-payload-migration analyze --verbose 2>&1 | grep -E "(pool|connection)"

Check for connection leaks

ts-wp-payload-migration analyze --verbose 2>&1 | grep -E "(release|cleanup)"
`

#### File Permission Issues

`bash


Ensure read access to WordPress directory

chmod -R 755 /path/to/wordpress

Check file ownership

ls -la /path/to/wordpress
`

#### Memory Issues with Large Sites

`bash


Increase Node.js memory limit


node --max-old-space-size=4096 ./dist/run.mjs analyze
`

$3

`bash


Enable debug logging

DEBUG=wp-migration:* ts-wp-payload-migration analyze /path/to/wordpress

Verbose output

ts-wp-payload-migration analyze /path/to/wordpress --verbose
