+
+## Module Development
+
+Create custom modules to extend server functionality:
+
+```javascript
+// modules/mod_example.js
+module.exports = {
+  name: 'example',
+  version: '1.0.0',
+  
+  load(module) {
+    const { logger, config, stanzaRouter } = module.api;
+    
+    logger.info('Example module loaded');
+    
+    // Hook into events
+    stanzaRouter.on('message', (stanza, session) => {
+      logger.debug('Message received:', stanza.toString());
+    });
+  },
+  
+  unload(module) {
+    module.api.logger.info('Example module unloaded');
+  }
+};
+```
+
+## API Reference
+
+### Session API
+
+```javascript
+// Create a session
+const session = sessionManager.createSession({
+  id: 'session-id',
+  jid: 'user@domain/resource',
+  type: 'c2s'
+});
+
+// Get session by JID
+const session = sessionManager.getSessionByJid('user@domain/resource');
+
+// Close session
+sessionManager.closeSession(sessionId);
+```
+
+### Storage API
+
+```javascript
+// Get a store
+const store = storageManager.getStore('domain', 'storeName');
+
+// Store data
+await store.set('key', { data: 'value' });
+
+// Retrieve data
+const data = await store.get('key');
+
+// Find data
+const results = await store.find(item => item.data === 'value');
+```
+
+### Stanza Routing
+
+```javascript
+// Route a stanza
+stanzaRouter.route(stanza, session);
+
+// Add a filter
+stanzaRouter.addFilter((stanza, session) => {
+  // Return false to block stanza
+  return true;
+});
+
+// Listen for events
+stanzaRouter.on('message', (stanza, session) => {
+  // Handle message
+});
+```
+
+## Security
+
+### Best Practices
+
+1. **TLS/SSL**: Always enable TLS for production
+2. **Authentication**: Use strong authentication mechanisms
+3. **Rate Limiting**: Configure rate limits to prevent abuse
+4. **Connection Limits**: Set per-IP connection limits
+5. **Input Validation**: Validate all stanza content
+6. **Logging**: Monitor logs for suspicious activity
+
+### Configuration
+
+```yaml
+security:
+  maxStanzaSize: 262144
+  connectionTimeout: 60000
+  maxConnectionsPerIP: 5
+  tlsCiphers: "HIGH:!aNULL:!MD5"
+
+rateLimit:
+  enabled: true
+  maxPointsPerSecond: 10
+  blockDuration: 60
+```
+
+## Performance
+
+### Optimization Tips
+
+1. **Clustering**: Run multiple instances behind a load balancer
+2. **Storage**: Use proper database for production (not memory)
+3. **Caching**: Enable caching for frequently accessed data
+4. **Compression**: Enable stream compression
+5. **Monitoring**: Use monitoring tools to track performance
+
+### Metrics
+
+The server exposes metrics for monitoring:
+- Active sessions
+- Message throughput
+- CPU and memory usage
+- Storage operations
+- Error rates
+
+## Troubleshooting
+
+### Common Issues
+
+#### Connection Refused
+- Check if the server is running
+- Verify port configuration
+- Check firewall settings
+
+#### Authentication Failed
+- Verify credentials
+- Check authentication backend
+- Review logs for errors
+
+#### TLS Errors
+- Verify certificate paths
+- Check certificate validity
+- Ensure proper permissions
+
+### Debug Mode
+
+Enable debug logging:
+
+```bash
+LOG_LEVEL=debug npm start
+```

+
+## Module API
+
+See [MODULE_DEVELOPMENT.md](MODULE_DEVELOPMENT.md) for detailed module API documentation.
+
+## Error Handling
+
+All async operations should be wrapped in try-catch:

+} catch (error) {
+  logger.error('Failed to start server:', error);
+  process.exit(1);
+}
+```
+
+## Events
+
+The server uses EventEmitter for event-driven architecture:
+
+```javascript
+sessionManager.on('session:authenticated', (session) => {

+# Module Development Guide
+
+## Introduction
+
+Modules are the primary way to extend the Prosody Node.js server. They can add new features, handle stanzas, store data, and integrate with external services.
+
+## Module Structure
+
+A basic module consists of a JavaScript file that exports an object with specific properties:
+
+```javascript
+module.exports = {
+  name: 'example',
+  version: '1.0.0',
+  description: 'An example module',
+  author: 'Your Name',
+  dependencies: [], // Other modules this depends on
+  
+  load(module) {
+    // Called when module is loaded
+  },
+  
+  unload(module) {
+    // Called when module is unloaded
+  }
+};
+```
+
+## Module API
+
+The `module` object passed to `load()` provides access to the server API:
+
+### Properties
+
+- `module.name` - Module name
+- `module.host` - Virtual host this module is loaded for
+- `module.api` - API object with helper functions
+
+### API Object
+
+```javascript
+module.api = {
+  config,              // Configuration manager
+  hostManager,         // Host manager
+  sessionManager,      // Session manager
+  stanzaRouter,        // Stanza router
+  storageManager,      // Storage manager
+  events,              // Event emitter
+  logger,              // Logger instance
+  
+  // Helper methods
+  getConfig(key, defaultValue),
+  getGlobalConfig(key, defaultValue),
+  getHostConfig(key, defaultValue),
+  require(moduleName)  // Load another module
+};
+```
+
+## Examples
+
+### 1. Simple Echo Module
+
+```javascript
+// modules/mod_echo.js
+module.exports = {
+  name: 'echo',
+  version: '1.0.0',
+  description: 'Echoes messages back to sender',
+  
+  load(module) {
+    const { logger, stanzaRouter } = module.api;
+    
+    logger.info('Echo module loaded');
+    
+    module.hook('message', (stanza, session) => {
+      if (stanza.attrs.type === 'chat') {
+        const body = stanza.getChildText('body');
+        if (body) {
+          // Create echo response
+          const response = stanza.clone();
+          response.attrs.from = stanza.attrs.to;
+          response.attrs.to = stanza.attrs.from;
+          
+          session.send(response);
+          logger.debug(`Echoed message to ${stanza.attrs.from}`);
+        }
+      }
+    });
+  }
+};
+```
+
+### 2. Message Logger Module
+
+```javascript
+// modules/mod_message_logger.js
+module.exports = {
+  name: 'message_logger',
+  version: '1.0.0',
+  description: 'Logs all messages to storage',
+  
+  async load(module) {
+    const { logger, stanzaRouter, storageManager } = module.api;
+    const store = storageManager.getStore(module.host, 'message_log');
+    
+    logger.info('Message logger module loaded');
+    
+    stanzaRouter.on('message', async (stanza, session) => {
+      try {
+        const logEntry = {
+          timestamp: Date.now(),
+          from: stanza.attrs.from,
+          to: stanza.attrs.to,
+          type: stanza.attrs.type,
+          body: stanza.getChildText('body')
+        };
+        
+        const key = `msg_${Date.now()}_${Math.random()}`;
+        await store.set(key, logEntry);
+        
+        logger.debug('Message logged');
+      } catch (error) {
+        logger.error('Failed to log message:', error);
+      }
+    });
+  }
+};
+```
+
+### 3. User Statistics Module
+
+```javascript
+// modules/mod_user_stats.js
+module.exports = {
+  name: 'user_stats',
+  version: '1.0.0',
+  description: 'Tracks user statistics',
+  
+  load(module) {
+    const { logger, sessionManager, storageManager } = module.api;
+    const store = storageManager.getStore(module.host, 'user_stats');
+    
+    const stats = {
+      totalMessages: 0,
+      totalPresence: 0,
+      onlineUsers: new Set()
+    };
+    
+    // Track sessions
+    sessionManager.on('session:authenticated', (session) => {
+      stats.onlineUsers.add(session.bareJid);
+      logger.info(`User online: ${session.bareJid} (total: ${stats.onlineUsers.size})`);
+    });
+    
+    sessionManager.on('session:closed', (session) => {
+      stats.onlineUsers.delete(session.bareJid);
+      logger.info(`User offline: ${session.bareJid} (total: ${stats.onlineUsers.size})`);
+    });
+    
+    // Track stanzas
+    module.on('message', () => {
+      stats.totalMessages++;
+    });
+    
+    module.on('presence', () => {
+      stats.totalPresence++;
+    });
+    
+    // Expose stats via IQ
+    module.hook('iq', (stanza, session) => {
+      if (stanza.attrs.type === 'get') {
+        const query = stanza.getChild('query');
+        if (query && query.attrs.xmlns === 'http://example.com/stats') {
+          const response = new ltx.Element('iq', {
+            type: 'result',
+            id: stanza.attrs.id,
+            to: stanza.attrs.from
+          }).c('query', { xmlns: 'http://example.com/stats' })
+            .c('stat', { name: 'messages' }).t(stats.totalMessages.toString()).up()
+            .c('stat', { name: 'presence' }).t(stats.totalPresence.toString()).up()
+            .c('stat', { name: 'online' }).t(stats.onlineUsers.size.toString());
+          
+          session.send(response);
+          return true; // Handled
+        }
+      }
+    });
+  }
+};
+```
+
+### 4. Rate Limiting Module
+
+```javascript
+// modules/mod_rate_limit.js
+const { RateLimiterMemory } = require('rate-limiter-flexible');
+
+module.exports = {
+  name: 'rate_limit',
+  version: '1.0.0',
+  description: 'Rate limits stanzas per user',
+  
+  load(module) {
+    const { logger, stanzaRouter, config } = module.api;
+    
+    const limiter = new RateLimiterMemory({
+      points: module.api.getConfig('points', 10),
+      duration: module.api.getConfig('duration', 1)
+    });
+    
+    // Add filter to stanza router
+    stanzaRouter.addFilter(async (stanza, session) => {
+      if (!session || !session.bareJid) return true;
+      
+      try {
+        await limiter.consume(session.bareJid);
+        return true; // Allow stanza
+      } catch (error) {
+        logger.warn(`Rate limit exceeded for ${session.bareJid}`);
+        return false; // Block stanza
+      }
+    });
+    
+    logger.info('Rate limiting enabled');
+  }
+};
+```
+
+## Hooks and Events
+
+### Stanza Events
+
+- `message` - Message stanza received
+- `presence` - Presence stanza received
+- `iq` - IQ stanza received
+- `iq:get` - IQ get request
+- `iq:set` - IQ set request
+- `iq:result` - IQ result
+- `iq:error` - IQ error
+
+### Session Events
+
+- `session:created` - New session created
+- `session:authenticated` - Session authenticated
+- `session:closed` - Session closed
+
+### Server Events
+
+- `server:started` - Server started
+- `server:stopped` - Server stopped
+
+## Storage
+
+Modules can store persistent data:
+
+```javascript
+const store = storageManager.getStore(module.host, 'mydata');
+
+// Store data
+await store.set('key', { data: 'value' });
+
+// Retrieve data
+const data = await store.get('key');
+
+// Delete data
+await store.delete('key');
+
+// Find data
+const results = await store.find(item => item.type === 'important');
+```
+
+## Configuration
+
+Modules can access configuration:
+
+```javascript
+// Module-specific config from moduleConfig section
+const enabled = module.api.getConfig('enabled', true);
+
+// Global config
+const domain = module.api.getGlobalConfig('server.domain');
+
+// Host-specific config
+const modules = module.api.getHostConfig('modules', []);
+```
+
+## Best Practices
+
+1. **Error Handling**: Always use try-catch blocks
+2. **Logging**: Log important events and errors
+3. **Cleanup**: Implement proper cleanup in `unload()`
+4. **Performance**: Avoid blocking operations
+5. **Testing**: Write tests for your modules
+6. **Documentation**: Document module configuration
+
+## Testing
+
+```javascript
+// test/mod_example.test.js
+const ModuleManager = require('../src/core/module-manager');
+
+describe('Example Module', () => {
+  it('should load successfully', async () => {
+    // Test module loading
+  });
+  
+  it('should handle messages', async () => {
+    // Test message handling
+  });
+});
+```
+
+## Publishing
+
+To share your module:
+
+1. Create a repository
+2. Add proper documentation
+3. Include example configuration
+4. Publish to npm (optional)

+
+### HTTP File Upload
+
+```yaml
+modules:
+  global:
+    - http_files
+    
+moduleConfig:
+  fileSharing:
+    enabled: true
+    maxFileSize: 10485760
+    uploadPath: ./uploads
+```
+
+## Security Setup
+
+### Enable TLS
+
+1. Generate certificates:
+
+```bash
+mkdir -p certs
+cd certs
+
+# Self-signed certificate (development only)
+openssl req -x509 -newkey rsa:4096 -keyout server.key -out server.crt -days 365 -nodes
+```
+
+2. Configure:
+
+```yaml
+network:
+  c2s:
+    tls:
+      enabled: true
+      required: false
+```
+
+```bash
+TLS_CERT_PATH=./certs/server.crt
+TLS_KEY_PATH=./certs/server.key
+```
+
+### Enable Rate Limiting
+
+```yaml
+rateLimit:
+  enabled: true
+  maxPointsPerSecond: 10
+  blockDuration: 60
+```
+
+### Set Connection Limits
+
+```yaml
+security:
+  maxConnectionsPerIP: 5
+  connectionTimeout: 60000
+```
+
+## Monitoring
+
+### View Logs
+
+```bash
+tail -f logs/prosody-nodejs.log
+```
+
+### Enable Debug Logging
+
+```bash
+LOG_LEVEL=debug npm start
+```
+
+## Next Steps
+
+- Read [Configuration Guide](CONFIGURATION.md)
+- Learn about [Module Development](MODULE_DEVELOPMENT.md)
+- Check [API Documentation](API.md)
+- See [Examples](../examples/)
+
+## Common Issues
+
+### Port Already in Use
+
+```
+Error: listen EADDRINUSE: address already in use :::5222
+```
+
+Solution: Change port in configuration or stop other XMPP server.
+
+### Permission Denied
+
+```
+Error: listen EACCES: permission denied 0.0.0.0:5222
+```
+
+Solution: Use port > 1024 or run with sudo (not recommended).
+
+### TLS Certificate Error
+
+```
+TLS client error: unable to verify certificate
+```
+
+Solution: Use proper certificates or configure client to accept self-signed.

+- presence - Availability
+- iq - Info/Query requests
+
+### Modules
+Extend server functionality:
+- Load per host
+- Hook into events
+- Access server API
+
+### Storage
+Persistent data:
+- Per-host isolation
+- Multiple backends
+- Key-value or document
