In this tutorial we are going to pass data to html files/templates.
How to pass data to frontend ?
data is the variable we going to pass to frontend.
tmpl.ExecuteTemplate(w, "index.html", data)

It is used to fetch data from backend.
Golang file
package main
import (
"html/template"
"net/http"
)
func main() {
data := "data passed to index page"
tmpl, _ := template.ParseGlob("templates/*.html")
http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
tmpl.ExecuteTemplate(w, "index.html", data)
})
http.ListenAndServe(":8080", nil)
}
