How to Use html/template in Go

Use html/template to safely render HTML by parsing a template string, executing it with data, and writing the result to an output stream.

package main

import (
	"html/template"
	"os"
)

func main() {
	tmpl, err := template.New("page").Parse(`Hello, {{.Name}}!`)
	if err != nil {
		panic(err)
	}
	data := struct{ Name string }{Name: "World"}
	err = tmpl.Execute(os.Stdout, data)
	if err != nil {
		panic(err)
	}
}

The html/template library in Go lets you create HTML pages by mixing static text with dynamic data while automatically preventing security attacks like script injection. Think of it as a fill-in-the-blank form where the blanks are safely replaced with your data before showing the page to a user.
