Go on GAE: Auto-reload / refresh of HTML templates using the template pkg

If you wonder why the changes in your template.html aren't reflected on the server and whether it's not a bug — ...no, it's a feature... ;)

 

The solution to reparase your HTML template — at least while you're in dev mode — is to appropriately incorporate this code snippet into your app.

 

var myTemplate = template.MustParseFile("template.html", nil) 
func reparseHTMLtemplate(w http.ResponseWriter, r *http.Request) {

myTemplate, err = template.ParseFile("template.html", nil) 

fmt.Fprintln(w, "reloaded / refreshed / reparsed:", err) 

}

 

Thanks to Andrew Gerrand for this solution!
