Example of rendering a template in Go.

template.go

package main

import (
	. "fmt"
	"net/http"
	"html/template"
	"log"
)

type User struct {
	FirstName string
}

func render(w http.ResponseWriter, tmpl string, data map[string]interface{}){
	tmpl = Sprintf("tmpl/%s", tmpl)
	t, err := template.ParseFiles(tmpl)

	if err != nil{
		log.Print("template parsing error: ", err)
	}

	// We pass our data map to the template
	err = t.Execute(w, data)

	if err != nil{
		log.Print("template executing error: ", err)
	}
}

func handler(w http.ResponseWriter, r *http.Request) {
	u := User{
		FirstName: "Nathan",
	}

	render(w, "welcome.html", map[string]interface{} {
		"FirstName": u.FirstName,
	})
}

func main() {
	Println("Running server @ localhost:6800")
	http.HandleFunc("/", handler)
	http.ListenAndServe(":6800", nil)
