A go-sitemap-generator is the easiest way to generate Sitemaps in Go.

As of version 2.0.0, This Repo is available as a Go module.

package main

import (
	"github.com/ikeikeikeike/go-sitemap-generator/v2/stm"
)


func main() {
	sm := stm.NewSitemap(1)

	// Create method must be called first before adding entries to
	// the sitemap.
	sm.Create()

	sm.Add(stm.URL{{"loc", "home"}, {"changefreq", "always"}, {"mobile", true}})
	sm.Add(stm.URL{{"loc", "readme"}})
	sm.Add(stm.URL{{"loc", "aboutme"}, {"priority", 0.1}})

	sm.Finalize().PingSearchEngines()
}

Then

$ go build

Installation (Legacy download instead of a Go module.)

$ go get gopkg.in/ikeikeikeike/go-sitemap-generator.v1/stm
$ go get gopkg.in/ikeikeikeike/go-sitemap-generator.v2/stm

Features

Current Features or To-Do

• Supports: generate kind of some sitemaps.
  • News sitemaps
  • Video sitemaps
  • Image sitemaps
  • Geo sitemaps
  • Mobile sitemaps
  • PageMap sitemap
  • Alternate Links
• Supports: adapters for sitemap storage.
  • Filesystem
  • S3
• Customizable sitemap working
• Notifies search engines (Google, Bing) of new sitemaps
• Gives you complete control over your sitemap contents and naming scheme

Getting Started

Setting concurrency

To disable concurrency, set number of CPUs to 1.

sm := stm.NewSitemap(1)

If you want to set max CPUs that are available, set number of CPUs <= 0.

sm := stm.NewSitemap(0)

Preventing Output

To disable all non-essential output you can set sm.SetVerbose to false. To disable output inline use the following:

sm := stm.NewSitemap(1)
sm.SetVerbose(false)

Pinging Search Engines

PingSearchEngines notifies search engines of changes once a sitemap has been generated or changed. The library will append Google and Bing to any engines passed in to the function.

sm.Finalize().PingSearchEngines()

If you want to add new search engine, you can pass that in to the function:

sm.Finalize().PingSearchEngines("http://newengine.com/ping?url=%s")

Options

// Your website's host name
sm.SetDefaultHost("http://www.example.com")

// The remote host where your sitemaps will be hosted
sm.SetSitemapsHost("http://s3.amazonaws.com/sitemap-generator/")

// The directory to write sitemaps to locally
sm.SetPublicPath("tmp/")

// Set this to a directory/path if you don't want to upload to the root of your `SitemapsHost`
sm.SetSitemapsPath("sitemaps/")

// Struct of `S3Adapter`
sm.SetAdapter(&stm.S3Adapter{Region: "ap-northeast-1", Bucket: "your-bucket", ACL: "public-read"})

// Change the output filename
sm.SetFilename("new_filename")

Upload sitemap to S3

Recently I disabled this module here.

package main

import (
	"github.com/aws/aws-sdk-go/aws/credentials"
	"github.com/ikeikeikeike/go-sitemap-generator/stm"
)

func main() {
	sm := stm.NewSitemap(1)
	sm.SetDefaultHost("http://example.com")
	sm.SetSitemapsPath("sitemap-generator") // default: public
	sm.SetSitemapsHost("http://s3.amazonaws.com/sitemap-generator/")
	sm.SetAdapter(&stm.S3Adapter{
		Region: "ap-northeast-1",
		Bucket: "your-bucket",
		ACL:    "public-read",
		Creds:  credentials.NewEnvCredentials(),
	})

	sm.Create()

	sm.Add(stm.URL{{"loc", "home"}, {"changefreq", "always"}, {"mobile", true}})
	sm.Add(stm.URL{{"loc", "readme"}})
	sm.Add(stm.URL{{"loc", "aboutme"}, {"priority", 0.1}})

	sm.Finalize().PingSearchEngines()
}

News sitemaps

sm.Add(stm.URL{
	{"loc", "/news"},
	{"news", stm.URL{
	{"publication", stm.URL{
		{"name",     "Example"},
		{"language", "en"},
	},
	},
	{"title",            "My Article"},
	{"keywords",         "my article, articles about myself"},
	{"stock_tickers",    "SAO:PETR3"},
	{"publication_date", "2011-08-22"},
	{"access",           "Subscription"},
	{"genres",           "PressRelease"},
},},})

Look at Creating a Google News Sitemap as required.

Video sitemaps

sm.Add(stm.URL{
	{"loc", "/videos"},
	{"video", stm.URL{
	{"thumbnail_loc", "http://www.example.com/video1_thumbnail.png"},
	{"title",         "Title"},
	{"description",   "Description"},
	{"content_loc",   "http://www.example.com/cool_video.mpg"},
	{"category",      "Category"},
	{"tag",           []string{"one", "two", "three"}},
    {"player_loc",    stm.Attrs{"https://example.com/p/flash/moogaloop/6.2.9/moogaloop.swf?clip_id=26", map[string]string{"allow_embed": "Yes", "autoplay": "autoplay=1"}},},
},
},
})

Look at Video sitemaps as required.

Image sitemaps

sm.Add(stm.URL{
	{"loc", "/images"},
	{"image", []stm.URL{
	{{"loc", "http://www.example.com/image.png"}, {"title", "Image"}},
	{{"loc", "http://www.example.com/image1.png"}, {"title", "Image1"}},
},},
})

Look at Image sitemaps as required.

Geo sitemaps

sm.Add(stm.URL{
	{"loc", "/geos"},
	{"geo", stm.URL{
	{"format", "kml"},
},},
})

Couldn't find Geo sitemaps example, although it's similar to:

<url>
	<loc>/geos</loc>
	<geo:geo>
		<geo:format>kml</geo:format>
	</geo:geo>
</url>

Mobile sitemaps

sm.Add(stm.URL{{"loc", "mobiles"}, {"mobile", true}})

Look at Feature phone sitemaps as required.

Alternate links

sm.Add(stm.URL{{"loc", "alternates"}, {"xhtml:link", []Attr{
  {
    "rel":      "alternate",
    "hreflang": "zh-tw",
    "href":     loc + "?locale=zh-tw",
  },
  {
    "rel":      "alternate",
    "hreflang": "en-us",
    "href":     loc + "?locale=en-us",
  },
}}}})

Look at localized versions as required.

Webserver example

package main

import (
	"log"
	"net/http"

	"github.com/ikeikeikeike/go-sitemap-generator/stm"
)

func buildSitemap() *stm.Sitemap {
	sm := stm.NewSitemap(1)
	sm.SetDefaultHost("http://example.com")

	sm.Create()
	sm.Add(stm.URL{{"loc", "/"}, {"changefreq", "daily"}})

	// Note: Do not call `sm.Finalize()` because it flushes
	// the underlying data structure from memory to disk.

	return sm
}

func main() {
	sm := buildSitemap()

	mux := http.NewServeMux()
	mux.HandleFunc("/sitemap.xml", func(w http.ResponseWriter, r *http.Request) {
		// Go's webserver automatically sets the correct `Content-Type` header.
		w.Write(sm.XMLContent())
		return
	})

	log.Fatal(http.ListenAndServe(":8080", mux))
}
