Automatically create sitemap.xml

Example

package main

import (
	"encoding/xml"
	"fmt"
	"os"
	"time"
)

type SitemapIndex struct {
	XMLName xml.Name `xml:"sitemapindex"`
	Xmlns   string   `xml:"xmlns,attr"`
	Sitemap []Sitemap
}

type Sitemap struct {
	Loc     string    `xml:"loc"`
	LastMod time.Time `xml:"lastmod"`
}

func main() {
	urls := []string{
		"https://example.com/page1",
		"https://example.com/page2",
		"https://example.com/page3",
	}

	sitemap := GenerateSitemap(urls)
	if err := SaveSitemap(sitemap, "sitemap.xml"); err != nil {
		fmt.Println("Failed to save sitemap:", err)
		return
	}

	fmt.Println("Sitemap generated successfully!")
}

func GenerateSitemap(urls []string) SitemapIndex {
	var sitemapIndex SitemapIndex
	now := time.Now()

	for _, url := range urls {
		sitemap := Sitemap{
			Loc:     url,
			LastMod: now,
		}
		sitemapIndex.Sitemap = append(sitemapIndex.Sitemap, sitemap)
	}

	return sitemapIndex
}

func SaveSitemap(sitemap SitemapIndex, filename string) error {
	sitemapIndexXml, err := xml.MarshalIndent(sitemap, "", "  ")
	if err != nil {
		return err
	}

	xmlStr := xml.Header + string(sitemapIndexXml)
	if err := os.WriteFile(filename, []byte(xmlStr), os.ModePerm); err != nil {
		return err
	}

	return nil
}

With Go Fiber

package main

import (
 "encoding/xml"
 "github.com/gofiber/fiber/v2"
 "io/ioutil"
 "time"
)

type SitemapIndex struct {
 XMLName xml.Name `xml:"sitemapindex"`
 Xmlns   string   `xml:"xmlns,attr"`
 Sitemap []Sitemap
}

type Sitemap struct {
 Loc     string    `xml:"loc"`
 LastMod time.Time `xml:"lastmod"`
}

func main() {
 app := fiber.New()

 app.Get("/sitemap.xml", func(c *fiber.Ctx) error {
  urls := []string{
   "https://example.com/page1",
   "https://example.com/page2",
   "https://example.com/page3",
  }
  sitemap := GenerateSitemap(urls)

  // Set the response headers
  c.Set(fiber.HeaderContentType, fiber.MIMEApplicationXMLCharsetUTF8)
  c.Set(fiber.HeaderContentDisposition, "attachment; filename=sitemap.xml")

  // Marshal the sitemap to XML
  sitemapXML, err := xml.MarshalIndent(sitemap, "", "  ")
  if err != nil {
   return err
  }

  // Return the sitemap XML as response
  return c.Send(sitemapXML)
 })

 err := app.Listen(":3000")
 if err != nil {
  panic(err)
 }
}

func GenerateSitemap(urls []string) SitemapIndex {
 var sitemapIndex SitemapIndex
 now := time.Now()

 for _, url := range urls {
  sitemap := Sitemap{
   Loc:     url,
   LastMod: now,
  }
  sitemapIndex.Sitemap = append(sitemapIndex.Sitemap, sitemap)
 }

 return sitemapIndex
}
