  • instead of Must (which panics) use functions that return errors and that function should return an error
  • instead of hardcoded "templates/*.html" pass it as function parameter

This code can be shortened to

// import  //	htmlTmpl "html/template" //	textTmpl "text/template" type TextTemplateRenderer struct { Templates *textTmpl.Template } func (t *TextTemplateRenderer) Render(w io.Writer, name string, data interface{}, c Context) error { return t.Templates.ExecuteTemplate(w, name, data) } type HTMLTemplateRenderer struct { Templates *htmlTmpl.Template } func (t *HTMLTemplateRenderer) Render(w io.Writer, name string, data interface{}, c Context) error { return t.Templates.ExecuteTemplate(w, name, data) }

and use as

e.Renderer = &echo.HTMLTemplateRenderer{ Templates: template.Must(template.ParseGlob("templates/*.html")),	}

(I'm new in both of Go, and Echo.)
When I tried it as a test, I used my own repository and imported it, not compiled.
So I don't know why it returns an error.
This is a recommendation, this is an idea that you could implement, an idea that will make it a little bit more beginner-friendly, as the current way of middleware is not a very beginner-friendly way to make a simple app.
Thanks for reading,

I've allowed edits by maintainers, so you could implement it the right way.
