The examples that I have seen online about how to use Go template did not mention that parseFiles method required the full path to the template file while the ExecuteTemplate method needs just the template name. Below I demonstrate this point!

First let me show you the $GOPATH/src/templateExample/templates/index.template file to define the template.

Hello {{.UserName}}!

And here is the Go code. I placed it in a file called $GOPATH/src/templateExample/examples/parse-template-file.go

package main

import (

type Person struct {
	UserName string

func main() {
	p := &Person{UserName: "David"}
	templatePath := "../templates/"
	templateName := "index.template"
	tmpl, err := template.ParseFiles(templatePath + "/" + templateName)
	if err != nil {
	err = tmpl.ExecuteTemplate(os.Stdout, templateName, p)
	if err != nil {

The Go code is executed like this:

cd $GOPATH/src/templateExample/examples
go run parse-template-file.go
