Is Go a Web Server?

Is Go a Web Server?

Go, also known as Golang, is a powerful programming language that was developed by Google. It has gained popularity for its simplicity, performance, and scalability. While Go is not specifically designed to be a web server, it does come with a built-in package called “net/http” that allows developers to create web servers and handle HTTP requests.

Creating a Simple Web Server in Go

To create a basic web server in Go, you only need a few lines of code. Let’s take a look at an example:

package main

import (

func handler(w http.ResponseWriter, r *http.Request) {
    fmt.Fprintf(w, "Hello World!")

func main() {
    http.HandleFunc("/", handler)
    http.ListenAndServe(":8080", nil)

In the code above, we import the necessary packages – “fmt” for formatting strings and “net/http” for handling HTTP requests. We define a function called “handler” that takes in an http.ResponseWriter and an http.Request as parameters. This function handles the incoming HTTP request and writes the response to the writer.

The main function sets up the route for our web server using the “/” pattern and associates it with our handler function. Finally, we start the server using the “ListenAndServe” function on port 8080.

Handling Different Routes

In addition to handling the root route (“/”), you can also handle different routes by defining additional handlers. For example:

func aboutHandler(w http.Fprintf(w, "This is the About page!")

func contactHandler(w http.Fprintf(w, "Contact us at")

func main() {
    http.HandleFunc("/about", aboutHandler)
    http.HandleFunc("/contact", contactHandler)
    http.ListenAndServe(":8080", nil)

In this updated code snippet, we define two additional handler functions – “aboutHandler” and “contactHandler” – to handle the “/about” and “/contact” routes, respectively. Each handler function writes a specific response to the writer.


In conclusion, while Go is not specifically designed as a web server, it does come with a built-in package that allows developers to create web servers and handle HTTP requests. With its simplicity and performance, Go is an excellent choice for building web applications.

By utilizing the “net/http” package and defining handler functions for different routes, you can easily create a web server in Go. Whether you’re building a simple API or a complex web application, Go’s concurrency model and efficient runtime make it a powerful tool for web development.
