Creating Simple Server in Go - 02

#go
  • First check the Go version by running the command 
go version
Enter fullscreen mode Exit fullscreen mode
  • Create a folder 
mkdir <folder_name>
Enter fullscreen mode Exit fullscreen mode
  • Switch to created folder 
cd <folder_name>
Enter fullscreen mode Exit fullscreen mode
  • Initialize the go project by running the given command. You will get go.mod file. 
go mod init <folder_name>
Enter fullscreen mode Exit fullscreen mode
  • Create a main.go file, use terminal or bash 
notepad main.go touch main.go
Enter fullscreen mode Exit fullscreen mode
  • Let's write some basic code in main.go file. 
package main import ( "fmt" "net/http" ) func handler(w http.ResponseWriter, r *http.Request) { fmt.Fprintf(w, "Hello From Go \n") fmt.Fprintf(w, "You are on %s route", r.URL.Path) } func main() { fmt.Println("Your Server is running on http://localhost:8000") http.HandleFunc("/", handler) http.ListenAndServe(":8000", nil) } /* --- 1. fmt , for formattting --- 2. net/http , for creating server --- both are standard package from go The fmt.Fprintf function expects at least two arguments: 1. an io.Writer (w) 2. a format specifier 3. optional arguments */
Enter fullscreen mode Exit fullscreen mode
  • Run the code by following command 
go run main.go
Enter fullscreen mode Exit fullscreen mode
  • You will see this output in console 
Your Server is running on http://localhost:8000
Enter fullscreen mode Exit fullscreen mode
  • Visit http://localhost:8000on browser & try to change path of URL. You will see 
Hello From Go You are on / route
Enter fullscreen mode Exit fullscreen mode

This was our simple server using Go.
That's for today. Thank You.
