How to Implement Best Practices for Global Logging in Go?

Best Practices for Global Logging in Go

When it comes to logging in Go, there are multiple approaches to consider when handling logs across multiple goroutines. Here are some questions to guide your decision-making:

Creating and Sharing a Single Logger

Can you create a single log.Logger and share it among the goroutines that need to log?

Answer: Yes, a log.Logger is thread-safe and can be used concurrently by multiple goroutines.

Passing Pointers to Loggers

Should you pass pointers to the log.Logger rather than the object itself?

Answer: Yes, log.New returns a *Logger, indicating that you should pass it as a pointer to avoid creating copies that can lead to concurrent write issues.

Creating Loggers per Goroutine or Function

Is it necessary to create a separate logger for each goroutine or function?

Answer: Generally, it's not advisable to create a separate logger for each goroutine or function. It may be more appropriate to group related tasks into components and create a logger for each component.

Global Logger Variables

Should you create a global logger as a global variable?

Answer: The answer to this question depends on your package's context. Consider whether you need to separate logging behavior based on different instances or components of your application.

In summary, the appropriate approach for global logging in Go depends on your specific requirements. By considering the options and answering the listed questions, you can choose the best strategy for your application's logging needs.
