How to Use Golang for Web Development?

In the field of web development, Golang or Go is quickly rising to the top of the list of most used programming languages. It is an open-source language developed by Google to accelerate and streamline programming. Go language is an ideal choice for building high-performance web applications as it is easy to learn, fast, and requires less memory.

We will talk about how to utilize Go for web development in this guide.

Golang Features for Web Development

Here are some features Golang offers for web development.

1: A Suitable Framework

To use Go for web development, we need to choose a suitable framework. Go has numerous web frameworks that make web development faster and more manageable. One of the most popular frameworks is Gorilla, which includes essential features like session management, security, and routing. Another popular framework is Beego, which provides a robust structure for web development and includes features like ORM, MVC architecture, and auto-generated API documentation.

2: Concurrency

Go uses concurrency, which is crucial in web development. With concurrency, a single Go program can run multiple processes simultaneously, improving performance and scalability. Goroutines are an essential feature of Go for concurrency, allowing developers to run several processes simultaneously without creating too many threads. Channels are another feature that allows communication between Goroutines, making it easy to distribute the work across multiple threads.

3: Packages

Go has a powerful standard library with several packages used in web development. The net/http package provides the necessary functionality for building web servers, while the html/template package allows us to create dynamic web page templates. Go’s standard library includes encryption, testing, and error-handling packages that save time while developing web applications.

4: Testing

The Go language comes with a built-in testing package, testing, that allows for efficient testing of web applications. The package includes necessary testing functions and methods to implement web application tests. The testing package supports standard testing methods like unit testing, benchmark testing, and integration testing.

5: Documentation

Go’s documentation is comprehensive and easy to understand, making learning the language less complicated for beginners. The Go documentation provides numerous code samples, tutorials, and guides for experienced programmers and beginners alike. The documentation also includes quick start guides, which help beginners get started with web development in the Go language.

Creating a Simple Web Application in Golang

We can now establish our first Golang web application that we have set up our development environment. In this example, we will build a simple web application that listens on a specified port and responds with a Hello, World! message when called. The code for our web application is as follows:

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)
    fmt.Println("Web Application created!")

In the above code, we define the handler function, which takes two arguments: w and r. w is an http.ResponseWriter object that allows us to write the response to the client, and r is an incoming http.Request object. The Hello, World! message is added to the response using the fmt.Fprintf method within the handler function.

The main function, which acts as the application’s entry point, is then defined. In the main function, we utilize the http.HandleFunc method to register the handler function as the handler for our application’s root route (“/”). Finally, we launch the web server on port 8080 using the http.ListenAndServe function.


Running the Web Application

To execute our web application, we must first navigate to the directory containing the hello.go file and execute the following command:

go run hello.go

This will compile our app and launch the web server. We can view our web application once the server is up and running by going to http://localhost:8080 in our web browser. We should see Hello, World! message in our browser.


Go is a fast, efficient, and scalable programming language ideal for web development. It is easier to learn than other programming languages, and its extensive documentation, packages, and frameworks make it a top choice for web developers. By utilizing Go standard library, concurrency, and testing package, web developers can create secure and high-performing web applications.
