I am having issues using extemplate library in my echo framework project.
Library :https://github.com/dannyvankooten/extemplate
My Code is below:
Enter code here...package main
import (
"fmt"
"io"
"net/http"
"github.com/dannyvankooten/extemplate"
"github.com/labstack/echo/v4"
)
// Template ...
type Template struct {
templates *extemplate.Extemplate
}
// Render ...
func (t *Template) Render(w io.Writer, name string, data interface{}, c
echo.Context) error {
err := t.templates.ExecuteTemplate(w, name, data)
if err != nil {
fmt.Println("error", err)
return err
}
return nil
}
// Page ...
type Page struct {
Name string
Content string
}
// Hello ...
func Hello(c echo.Context) error {
return c.Render(http.StatusOK, "hello.html", "Guys")
}
// About ...
func About(c echo.Context) error {
data := Page{
Name: "About", Content: `Lorem ipsum dolor sit amet, consectetur adipiscing
elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

Praesent tristique magna sit amet purus gravida.`,
}
return c.Render(http.StatusOK, "about.html", data)
}
func main() {
xt := &Template{}
err := xt.templates.ParseDir("templates/", []string{".html"})
if err != nil {
fmt.Println("ErrorExt: ", err)
}
e := echo.New()
e.Renderer = xt
e.GET("/hello", Hello)
e.GET("/about", About)
e.Logger.Fatal(e.Start(":4000"))
}
My folder structure where the template resides is below:
--main--
--templates--
--about.html--
--home.html--
--go.mod--
--go.sum--
I am using go modules for the project.
Why do I keep on getting these errors below:
panic: runtime error: invalid memory address or nil pointer dereference
