 import logger from '../utils/logger';
 export function errorHandler(

 ) {
  // Log all errors

    path: req.path,
    ip: req.ip,
    userId: req.user?.id,

  // Handle specific error types

 ```
 ### Authentication Implementation
 ```typescript
 // src/middleware/authenticate.ts
 import { Request, Response, NextFunction } from 'express';
 import jwt from 'jsonwebtoken';
 import { UserService } from '../services/userService';
 import { AuthorizationError } from '../utils/errors';
 interface TokenPayload {

  role: string;
  iat: number;
  exp: number;
 }
 export function authenticate(
  requiredRoles: string[] = []
 ) {
  return async (req: Request, res: Response, next: NextFunction) => {
    try {
      // Get token from authorization header
      const authHeader = req.headers.authorization;
      if (!authHeader || !authHeader.startsWith('Bearer ')) {
        throw new AuthorizationError('Authentication required');
      }
      const token = authHeader.split(' ')[1];
      // Verify token
      let payload: TokenPayload;
      try {
        payload = jwt.verify(
          token, 
          process.env.JWT_SECRET!
        ) as TokenPayload;
      } catch (err) {
        throw new AuthorizationError('Invalid token');
      }
      // Check token expiration
      const now = Math.floor(Date.now() / 1000);
      if (payload.exp < now) {
        throw new AuthorizationError('Token expired');
      }
      // Check role if required
      if (requiredRoles.length > 0 && !requiredRoles.includes(payload.role)) {
        throw new AuthorizationError('Insufficient permissions');
      }
      // Get user and attach to request
      const userService = new UserService();
      const user = await userService.findById(payload.userId);
      if (!user) {
        throw new AuthorizationError('User not found');
      }
      // Attach user to request object
      req.user = user;
      next();
    } catch (error) {
      next(error);
    }
  };
 }
 ```
 ### Custom Error Classes
 ```typescript
 // src/utils/errors.ts
 export class ValidationError extends Error {
  constructor(message: string) {
    super(message);
    this.name = 'ValidationError';
    Object.setPrototypeOf(this, ValidationError.prototype);
  }
 }
 export class NotFoundError extends Error {
  constructor(message: string) {
    super(message);
    this.name = 'NotFoundError';
    Object.setPrototypeOf(this, NotFoundError.prototype);
  }
 }
 export class AuthorizationError extends Error {
  constructor(message: string) {
    super(message);
    this.name = 'AuthorizationError';
    Object.setPrototypeOf(this, AuthorizationError.prototype);
  }
 }
 export class DatabaseError extends Error {
  constructor(message: string) {
    super(message);
    this.name = 'DatabaseError';
    Object.setPrototypeOf(this, DatabaseError.prototype);
  }
 }
 export class ServiceError extends Error {
  constructor(message: string) {
    super(message);
    this.name = 'ServiceError';
    Object.setPrototypeOf(this, ServiceError.prototype);
  }
 }

 ## Code Examples
 ### Express.js Application Setup
 ```typescript
 // src/app.ts
 import express from 'express';
 import cors from 'cors';
 import helmet from 'helmet';
 import compression from 'compression';
 import rateLimit from 'express-rate-limit';
 import { errorHandler } from './middleware/errorHandler';
 import { notFoundHandler } from './middleware/notFoundHandler';
 import { requestLogger } from './middleware/requestLogger';
 import routes from './routes';
 const app = express();
 // Middleware
 app.use(helmet()); // Security headers
 app.use(cors()); // CORS handling
 app.use(compression()); // Response compression
 app.use(express.json()); // Parse JSON bodies
 app.use(express.urlencoded({ extended: true })); // Parse URL-encoded bodies
 app.use(requestLogger); // Log all requests
 // Rate limiting
 const limiter = rateLimit({
  windowMs: 15 * 60 * 1000, // 15 minutes
  max: 100, // 100 requests per IP
  standardHeaders: true,
  legacyHeaders: false,
  message: 'Too many requests from this IP, please try again later',
 });
 app.use(limiter);
 // Routes
 app.use('/api', routes);
 // Error handling
 app.use(notFoundHandler);
 app.use(errorHandler);
 export default app;
 ```
 ### API Route Definition
 ```typescript
 // src/routes/userRoutes.ts
 import { Router } from 'express';
 import { UserController } from '../controllers/userController';
 import { UserService } from '../services/userService';
 import { UserRepository } from '../repositories/userRepository';
 import { authenticate } from '../middleware/authenticate';
 import { validateRequest } from '../middleware/validateRequest';
 import { createUserSchema, updateUserSchema } from '../validation/userSchemas';
 const router = Router();
 const userRepository = new UserRepository();
 const userService = new UserService(userRepository);
 const userController = new UserController(userService);
 router.get('/', 
  authenticate(['ADMIN']), 
  (req, res, next) => userController.getUsers(req, res, next)
 );
 router.get('/:id', 
  authenticate(), 
  (req, res, next) => userController.getUserById(req, res, next)
 );
 router.post('/', 
  validateRequest(createUserSchema), 
  (req, res, next) => userController.createUser(req, res, next)
 );
 router.put('/:id', 
  authenticate(), 
  validateRequest(updateUserSchema), 
  (req, res, next) => userController.updateUser(req, res, next)
 );
 router.delete('/:id', 
  authenticate(['ADMIN']), 
  (req, res, next) => userController.deleteUser(req, res, next)
 );
 export default router;
 ```
 ### Dependency Injection Setup
 ```typescript
 // src/config/container.ts
 import { Container } from 'inversify';
 import { TYPES } from './types';
 import { UserController } from '../controllers/userController';
 import { UserService } from '../services/userService';
 import { UserRepository } from '../repositories/userRepository';
 import { DatabaseConnection } from '../config/database';
 import { Logger } from '../utils/logger';
 const container = new Container();
 // Infrastructure
 container.bind<DatabaseConnection>(TYPES.DatabaseConnection).to(DatabaseConnection).inSingletonScope();
 container.bind<Logger>(TYPES.Logger).to(Logger).inSingletonScope();
 // Repositories
 container.bind<UserRepository>(TYPES.UserRepository).to(UserRepository).inSingletonScope();
 // Services
 container.bind<UserService>(TYPES.UserService).to(UserService).inSingletonScope();
 // Controllers
 container.bind<UserController>(TYPES.UserController).to(UserController).inSingletonScope();
 export { container };
 ```

 ## Best Practices
 ### Code Structure Best Practices
 - Keep files small and focused on a single responsibility
 - Use consistent naming conventions across the codebase
 - Group related functionality together
 - Separate business logic from infrastructure concerns
 - Maintain clear dependency boundaries
 ### API Design Best Practices
 - Use nouns for resource endpoints
 - Keep URLs clean and simple
 - Use HTTP methods appropriately
 - Return appropriate status codes
 - Document all endpoints
 ### Security Best Practices
 - Never trust client input
 - Implement proper authentication and authorization
 - Follow the principle of least privilege
 - Keep dependencies up to date
 - Run regular security scans
 ### Performance Best Practices
 - Implement appropriate caching
 - Optimize database queries
 - Use async/await for I/O operations
 - Monitor and optimize bottlenecks
 - Consider pagination for large data sets
 ### Testing Best Practices
 - Write tests at multiple levels (unit, integration, system)
 - Use test doubles (mocks, stubs, spies) appropriately
 - Aim for high code coverage
 - Test happy paths and edge cases
 - Incorporate testing into the development workflow
