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.
