Basic Example

Let’s start by creating a basic HTTP server example that responds with “Hello World!” when accessed.

Creating a simple “Hello World!” webpage using Go can be achieved by using the net/http package. We will learn more about net/http package in next chapter.

Create a new file, let’s call it main.go, and open it in your preferred code editor.

Add the following code to your main.go file:

package main
import (

func main() {
	http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
		fmt.Fprint(w, "Hello World!")
	http.ListenAndServe(":8080", nil)

Open a terminal, navigate to the directory containing your main.go file, and run the following command:

go run main.go

Open your web browser and navigate to http://localhost:8080. You should see “Hello World!” displayed on the webpage.

Congratulations, You have just created your first webpage using Go.
