How to generate routes and templates?

Question

go

There is a completely static site.
On bare html.
It needs to be translated to Go.
Here is the code, it works.

package main

import (
        "github.com/gin-gonic/contrib/renders/multitemplate"
        "github.com/gin-gonic/gin"
)

func main() {
        templates := multitemplate.New()
        templates.AddFromFiles("index",
                "templates/Base.html",
                "templates/Index.html")

        templates.AddFromFiles("contact",
                "templates/Base.html",
                "templates/Contact.html")

        router := gin.New()
        router.HTMLRender = templates

        router.GET("/index.html", func(c *gin.Context) {
                c.HTML(200, "index", gin.H{
                        "title": "Home",
                        "stuff": "Interesting home stuff",
                })
        })

        router.GET("/contact.html", func(c *gin.Context) {
                c.HTML(200, "contact", gin.H{
                        "title": "Contact",
                        "stuff": "Interesting contact stuff",
                })
        })
        router.Run(":5000")
}

Is there an option not to describe the routes each time and not to add a template for each case each time?
For example, the template folder contains the about.html file.
How can I make the route "/about.html" automatically created and the required template automatically added?
PS Tried to process it in a cycle.
Here is the code.
It even starts up.

package main

import (
        "github.com/gin-gonic/contrib/renders/multitemplate"
        "github.com/gin-gonic/gin"
        "path/filepath"
)

func main() {
        templates := multitemplate.New()
        files, _ := filepath.Glob("templates/*.html")
        for _, element := range files {
                name := element[10:]
                templates.AddFromFiles(name, "templates/Base_tmpl", element)
        }

But, when you try to access the route, you get the following:

curl  localhost:5000/contact.html
curl: (52) Empty reply from server

And here's the error:

Answer 1

Well, loop through all the files in your pages folder and do the same as written in the question, except that you will pull the names dynamically.

Answer 2

It's probably possible to use http.FileServer

package main

import (
  "log"
  "net/http"
)

func main() {
  // Simple static webserver:
  log.Fatal(http.ListenAndServe(":8080", http.FileServer(http.Dir("/usr/share/doc"))))
}

Here is the dock for http.FileServer

Answer 3

Hugo is a great static site generator in Go.
