Logging is a critical aspect of software development. It helps you track your application’s behavior, find bugs, and monitor its performance.

However, plain text logs can be challenging to navigate, especially in complex applications.

That’s where the “logx” package comes in. This GoLang package allows you to add color and formatting to your console log messages, making it easier to distinguish different types of log entries or to add emphasis to specific messages.

In this guide, we’ll show you how to make the most of “logx” and enhance your GoLang projects.


Before you get started with “logx,” there are a few prerequisites you need to meet:

  • You should have GoLang installed on your system.
  • A basic understanding of GoLang programming is helpful.

If you’re new to GoLang, you can follow the installation guide for your specific platform on the official GoLang website.


The first step is to install the “logx” package into your GoLang project. It’s a straightforward process using the go get command:

go get github.com/theritikchoure/logx

Don’t forget to import “logx” in your GoLang code:

import "github.com/theritikchoure/logx"

Now you’re ready to add some color to your logs.

Enabling Colorful Logging

By default, colorized logging is disabled in “logx.” You can enable or disable it by modifying the ColoringEnabled variable in your code. Setting it to true will enable colored output, while setting it to false will disable it (which is the default behavior):

logx.ColoringEnabled = true // Enable colorized logging
logx.ColoringEnabled = false // Disable colorized logging (default)

Basic Logging

The “logx” package provides the Log function to print log messages with specified foreground and background colors. If coloring is enabled, it will print colorful log entries; otherwise, it will print plain text.

logx.Log("This is a log message", logx.FGRED, logx.BGGREEN)

With a simple function call, you can make your logs more visually appealing and easier to distinguish.

Formatted Logging

For more complex log entries, you can use the Logf function. It works similarly to Go's fmt.Printf and allows you to format log messages and specify colors:

logx.Logf("User: %s logged in.", logx.FGBLUE, logx.BGWHITE, "JohnDoe")

This is handy when you need to insert dynamic values into your log messages.

Log Levels

To make your log entries even more informative, “logx” supports log levels like INFO, WARNING, ERROR, and SUCCESS. You can use the LogWithLevel function to display log messages with predefined background colors corresponding to these levels:

logx.LogWithLevel("An error occurred", "ERROR")

It’s an excellent way to categorize and distinguish log entries based on their significance.

Multiple Messages

Sometimes, you may want to log multiple messages with customized formatting options. “logx” provides the LogM function for this purpose. You can combine color codes and formatting options to create visually appealing log entries:

logx.LogM([]string{"Applying", "updates..."}, logx.FGBLUE, logx.BGYELLOW, logx.BOLD, logx.UNDERLINE)

With “logx,” you have the flexibility to design logs that suit your project’s needs.


Adding timestamps to your log entries can help you understand when specific events occurred. The LogWithTimestamp function simplifies this task:

logx.LogWithTimestamp("System restarted", logx.FGCYAN, logx.BGWHITE)

Now you can track the timing of critical events effortlessly.

Logging to a File

In addition to standard output, “logx” allows you to log messages to a file. The LogToFile function opens the specified file for appending and logs the message to both the file and standard output:

logx.LogToFile("Log entry written to file", logx.FGRED, logx.BGGREEN, "log.txt")

This feature is handy for archiving logs and analyzing them later.

Best Practices

To make the most of “logx,” consider the following best practices:

  • Use appropriate log levels (INFO, WARNING, ERROR) to categorize log messages.
  • Maintain clean and organized logs by following a consistent format.
  • Embrace colorful logging to enhance log entry distinction.


Incorporating colorful and formatted logging into your GoLang projects is a simple yet powerful way to make your logs more informative and visually appealing. “logx” provides an easy-to-use package for achieving this goal, and this guide has demonstrated how to use it effectively. By categorizing log entries, adding timestamps, and employing best practices, you can improve your application’s log quality and save time debugging issues.
