How to Centralize Logrus Configuration in Go Applications?

Centralized Logging Configuration in Go with Logrus

Logrus is a popular logging package for Go applications. While it provides configurable options, managing these configurations across multiple source files can be cumbersome.

However, it is possible to achieve centralized configuration for logrus without having to set options in each file. Here are three effective approaches:

1. Global Log Variable: You can define a global log variable as follows:

import log "github.com/Sirupsen/logrus"

var log = logrus.New()

Now, all Logrus functions like log.SetOutput() will modify the global logger, applying these configurations throughout the application.

2. Custom Logger Wrapper: Define a custom package that wraps the Logrus logger and provides your own wrapper functions:

// package customlog

package customlog

import (
    "github.com/Sirupsen/logrus"
)

var logger = logrus.New()

func Info(args ...interface{}) {
    logger.Info(args...)
}

func Debug(args ...interface{}) {
    logger.Debug(args...)
}

In your application, import this custom package and use its functions instead:

import "customlog"

customlog.Info("This message will be logged through the central logger.")

3. Top-Level Functions: You can create top-level functions that encapsulate Logrus functions and modify the global logger:

import "github.com/Sirupsen/logrus"

func SetLevel(level logrus.Level) {
    logrus.SetLevel(level)
}

func SetFormatter(formatter logrus.Formatter) {
    logrus.SetFormatter(formatter)
}

With any of these approaches, you can centralize the management of logrus configurations in a single location, making it convenient to adjust logging settings in one place and have them applied throughout your application.
