Introduction

Golang is a programming language that is known for its speed, simplicity, and concurrency. It is a popular choice for building web applications and APIs.

Gorilla mux is a web framework for Golang that is known for its performance, flexibility, and ease of use. It is a popular choice for building web applications and APIs.

In this blog post, we will learn how to use Golang and gorilla mux to build a simple web application.

Prerequisites

Before we begin, we need to make sure that we have the following prerequisites installed:

• Golang: You can download Golang from the official website.

• gorilla mux: You can install gorilla mux with the following command:

  go get github.com/gorilla/mux

Creating a new project Once we have the prerequisites installed, we can create a new project. We can do this with the following command:

bash ``` mkdir my-golang-app

cd my-golang-app

This will create a new directory called my-golang-app. We will be working in this directory for the rest of the tutorial.

Creating a main.go file Now that we have created a new project, we need to create a main.go file. This file will contain the code for our web application.

go``` package main

import ( "fmt" "net/http" "github.com/gorilla/mux" )

func main() { // Create a new mux router. r := mux.NewRouter()

// Handle the "/" path. r.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) { fmt.Fprintf(w, "Hello, world!") })

// Listen and serve on port 8080. http.ListenAndServe(":8080", r) }

This code creates a new mux router and registers a handler for the "/" path. The handler simply prints "Hello, world!" to the response writer.

Starting the server

Now that we have created a web application, we can start the server. We can do this with the following command:

bash ``` go run main.go

This will start the server on port 8080. We can open a web browser and go to http://localhost:8080 to see our web application.

Conclusion

In this blog post, we learned how to use Golang and gorilla mux to build a simple web application. We created a new project, created a main.go file, and started the server. We can now open a web browser and see our web application.
