Best Practices for Error Handling in Express.js Applications

Effective error handling in your Express.js applications is crucial for maintaining a robust user experience. Here are some best practices:

• Centralized Error Handling: Create a centralized error handling middleware to catch errors from various routes and handle them uniformly.
• Use HTTP Status Codes: Always respond with appropriate HTTP status codes to indicate the result of the request (e.g., 404 for not found, 500 for server errors).
• Log Errors: Implement logging mechanisms to track errors using tools like Winston or Morgan, which can help in debugging and monitoring.
• Send User-Friendly Messages: Avoid exposing stack traces to users. Instead, send generic error messages while logging the detailed errors for internal use.

By following these best practices, you can ensure that your Express.js applications handle errors gracefully and provide a better experience for users.
