Logging ​

Logging is essential for tracking and debugging issues while building frontend apps. This section covers the importance of logging, best practices and the recommended tools for logging in frontend development at Hubtel.

Importance of Logging ​

Logging allows you to monitor the behavior of your application, track errors, and diagnose issues in production and development environments. By logging relevant information, you can gain insights into application performance, user interactions, and error occurrences, enabling you to identify and address issues more effectively.

Benefits of Logging: ​

  • Error Detection: Logs help detect errors and exceptions in the application code.
  • Performance Monitoring: Logs can be used to monitor performance metrics such as response times and resource utilization.
  • Debugging: Logs provide valuable information for debugging and troubleshooting issues.
  • Auditing: Logging user interactions and system events enables auditing and compliance with regulatory requirements.

Best Practices ​

When implementing logging in your frontend applications, consider the following best practices to ensure effective and efficient logging:

Best Practices for Logging: ​

  • Use Levels: Use different log levels (e.g., debug, info, warning, error) to categorize log messages based on their severity.
  • Include Context: Include relevant context information such as timestamps, request IDs, user IDs, and error stack traces in log messages.
  • Structured Logging: Use structured log formats (e.g., JSON) for better parsing and analysis of log data.

Using Event Publisher for Logging in Frontend Applications ​

At Hubtel, we use the Event Publisher library to log events and errors in our frontend applications. The Event Publisher library provides a simple and consistent way to log messages whiles in development to console and publish events to a centralized destination while in production.

For more information on using the Event Publisher library, refer to the Event Publisher documentation
