Go Logging

Introduction

Log effectively with the standard log package and structured logging.

This tutorial explains the concepts and provides practical examples you can run yourself.

What You Will Learn

• Understand the core idea behind go logging.
• See common usage patterns with clear examples.
• Avoid typical mistakes beginners make.

Basic Example

package main

import "fmt"

func main() {
    // Example code for Go Logging
    fmt.Println("Hello from Go Logging")
}

Key Concepts

Go emphasizes simplicity, clarity, and strong tooling. When working with go logging, keep these principles in mind:

1. Explicit is better than implicit.
2. Composition is preferred over inheritance.
3. Errors are values, not exceptions.

Common Patterns

Here is a slightly more advanced example demonstrating a typical pattern:

package main

import "fmt"

func main() {
    result := example("Go")
    fmt.Println(result)
}

func example(name string) string {
    return "Learning " + name + " with Go Logging"
}

Try It Yourself

1. Modify the example to accept user input.
2. Experiment with different values and observe the output.
3. Write a small test for the function you created.

Summary

Go Logging is an essential building block in Go programming. Practice the examples, explore the Go standard library, and move on to the next tutorial when you are comfortable.
