Template Rendering with `html/template`

HTML Templates

This lesson explains the main concept clearly with beginner-friendly examples and background so you can learn why the code works.

html/template auto‑escapes content, preventing XSS.

tmpl := template.Must(template.ParseFiles("index.html"))

type PageData struct { Title string; Items []string }

func handler(w http.ResponseWriter, r *http.Request) {
    data := PageData{Title: "My Site", Items: []string{"Go", "Docker", "K8s"}}
    tmpl.Execute(w, data)
}

Template syntax basics

<h1>{{ .Title }}</h1>
<ul>
{{ range .Items }}
    <li>{{ . }}</li>
{{ end }}
</ul>
