Day 15: Introduction to Logging in Express

I’m excited to be consistent on this journey! Logging records events in my application, which is vital for debugging errors and identifying what went wrong. This practice helps improve the overall performance and reliability of my app.

Key Benefits of Logging:

Debugging Errors: Quickly see what went wrong.

Monitoring Performance: Track response times and system health.

Understanding User Behavior: Analyze which features are being used.

Steps to Implement Logging:

Install Morgan: A simple and popular logging library.

Basic Logging: Integrate Morgan to log incoming HTTP requests.

Custom Log Formats: Tailor the log format for more detailed insights.

Save Logs to a File: Keep logs for future analysis.

Test Your Logging: Verify that logs are being recorded as expected.

Conclusion:

Keeping a record of what the application does helps us understand it and makes it better for users. By implementing logging in Express, I can effectively capture and analyze important events.
