I am doing some web develoment using the go programming language using the package html/template
. At some point of the code, I need to call the function template.ParseFiles(...)
so I can create a template from those files ad then execute it using temp.Execute(w,data)
. I would like to know if it is better to create the template on each request or to do it once in the main and declare a global variable.
Right now I do it on each request on my handle functions, like most tutorials do. However, I don't know If I'm wasting resources by doing it on each request instead of having them as global variables.
This is how it looks on each request
func ViewStats(w http.ResponseWriter, r *http.Request) {
//Get stuff from db and put them in data
//...
//return data to user
tmp, err := template.ParseFiles("views/guest-layout.html",
"views/stats.html")
if err != nil {
fmt.Println(err)
} else {
tmp.Execute(w,data)
}
}
I would like to know if this is better:
var temp1 template.Template
func main() {
temp1, err = template.ParseFiles("file1","file2")
//...
}
