Hello World

First, let's create a new file named main.go and add the following code:

package main

import "github.com/dinever/golf"

func mainHandler(ctx *golf.Context) {
  ctx.Send("Hello World!")
}

func main() {
  app := golf.New()
  app.Get("/", mainHandler)
  app.Run(":9000")
}

To run this program, use the following command:

$ go run main.go

Alternatively, you can also build this go source file into a binary executable program:

$ go build main.go

Run the compiled binary executable program directly:

$ ./main

This program listens to the port 9000 and returns "Hello World!" whenever a request comes to the root URL(/). For every other path, the program returns a 404 Not Found.
