Why Astro Sitemap

A Sitemap is an XML file that outlines all of the pages, videos, and files on your site. Search engines like Google read this file to crawl your site more efficiently. See Google's own advice on sitemaps to learn more.

A sitemap file is recommended for large multi-page sites. If you don't use a sitemap, most search engines will still be able to list your site's pages, but a sitemap is a great way to ensure that your site is as search engine friendly as possible.

With Astro Sitemap, you don't have to worry about creating this file: build your Astro site how you normally would, and the Astro Sitemap integration will crawl your routes and create the sitemap file.

Installation

Quick Install

The astro add command-line tool automates the installation for you. Run one of the following commands in a new terminal window. (If you aren't sure which package manager you're using, run the first command.) Then, follow the prompts, and type "y" in the terminal (meaning "yes") for each one.

# Using NPM
npx astro add sitemap
# Using Yarn
yarn astro add sitemap
# Using PNPM
pnpm astro add sitemap

If you run into any issues, feel free to report them to us on GitHub and try the manual installation steps below.

Manual Install

First, install the @astrojs/sitemap package using your package manager. If you're using npm or aren't sure, run this in the terminal:

npm install @astrojs/sitemap

Then, apply this integration to your astro.config.* file using the integrations property:

astro.config.mjs

import { defineConfig } from 'astro/config';
import sitemap from '@astrojs/sitemap';

export default defineConfig({
  // ...
  integrations: [sitemap()],
})

Usage

@astrojs/sitemap requires a deployment / site URL for generation. Add your site's URL under your astro.config.* using the site property. This must begin with http: or https:.

astro.config.mjs

import { defineConfig } from 'astro/config';
import sitemap from '@astrojs/sitemap';

export default defineConfig({
  // ...
  site: 'https://stargazers.club',
  integrations: [sitemap()],
})

Note that unlike other configuration options, site is set in the root defineConfig object, rather than inside the sitemap() call.

Now, build your site for production via the astro build command. You should find your sitemap under dist/ for both sitemap-index.xml and sitemap-0.xml!

Warning If you forget to add a site, you'll get a friendly warning when you build, and the sitemap-index.xml file won't be generated.

After verifying that the sitemaps are built, you can add them to your site's <head> and the robots.txt file for crawlers to pick up.

// src/layouts/Layout.astro
<head>
  <link rel="sitemap" href="/sitemap-index.xml">
</head>

User-agent: *
Allow: /

Sitemap: https://<YOUR SITE>/sitemap-index.xml

Example of generated files for a two-page website

sitemap-index.xml

  <sitemapindex xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">

  </sitemap>
</sitemapindex>

sitemap-0.xml

    <loc>https://stargazers.club/</loc>
  </url>
  <url>
    <loc>https://stargazers.club/second-page/</loc>
  </url>
</urlset>

Configuration

To configure this integration, pass an object to the sitemap() function call in astro.config.mjs.

astro.config.mjs

import { defineConfig } from 'astro/config';
import sitemap from '@astrojs/sitemap';

export default defineConfig({
  integrations: [sitemap({
    filter: ...
  })]
});

filter

All pages are included in your sitemap by default. By adding a custom filter function, you can filter included pages by URL.

astro.config.mjs

...
    sitemap({
      filter: (page) => page !== 'https://stargazers.club/secret-vip-lounge'
    }),

The function will be called for every page on your site. The page function parameter is the full URL of the page currently under considering, including your site domain. Return true to include the page in your sitemap, and false to leave it out.

To filter multiple pages, add arguments with target URLs.

astro.config.mjs

...
    sitemap({
      filter: (page) =>
        page !== "https://stargazers.club/secret-vip-lounge-1" &&
        page !== "https://stargazers.club/secret-vip-lounge-2" &&
        page !== "https://stargazers.club/secret-vip-lounge-3" &&
        page !== "https://stargazers.club/secret-vip-lounge-4",
    }),

customPages

In some cases, a page might be part of your deployed site but not part of your Astro project. If you'd like to include a page in your sitemap that isn't created by Astro, you can use this option.

astro.config.mjs

...
    sitemap({
      customPages: ['https://stargazers.club/external-page', 'https://stargazers.club/external-page2']
    }),

entryLimit

The maximum number entries per sitemap file. The default value is 45000. A sitemap index and multiple sitemaps are created if you have more entries. See this explanation of splitting up a large sitemap.

astro.config.mjs

import { defineConfig } from 'astro/config';
import sitemap from '@astrojs/sitemap';

export default defineConfig({
  site: 'https://stargazers.club',
  integrations: [
    sitemap({
      entryLimit: 10000,
    }),
  ],
});

changefreq, lastmod, and priority

These options correspond to the <changefreq>, <lastmod>, and <priority> tags in the Sitemap XML specification.

Note that changefreq and priority are ignored by Google.

Note Due to limitations of Astro's Integration API, this integration can't analyze a given page's source code. This configuration option can set changefreq, lastmod and priority on a site-wide basis; see the next option serialize for how you can set these values on a per-page basis.

astro.config.mjs

import { defineConfig } from 'astro/config';
import sitemap from '@astrojs/sitemap';

export default defineConfig({
  site: 'https://stargazers.club',
  integrations: [
    sitemap({
      changefreq: 'weekly',
      priority: 0.7,
      lastmod: new Date('2022-02-24'),
    }),
  ],
});

serialize

A function called for each sitemap entry just before writing to a disk. This function can be asynchronous.

It receives as its parameter a SitemapItem object that can have these properties:

url (absolute page URL). This is the only property that is guaranteed to be on SitemapItem.
changefreq
lastmod (ISO formatted date, String type)
priority
links.

This links property contains a LinkItem list of alternate pages including a parent page.

The LinkItem type has two fields: url (the fully-qualified URL for the version of this page for the specified language) and lang (a supported language code targeted by this version of the page).

The serialize function should return SitemapItem, touched or not.

The example below shows the ability to add sitemap specific properties individually.

astro.config.mjs

import { defineConfig } from 'astro/config';
import sitemap from '@astrojs/sitemap';

export default defineConfig({
  site: 'https://stargazers.club',
  integrations: [
    sitemap({
      serialize(item) {
        if (/exclude-from-sitemap/.test(item.url)) {
          return undefined;
        }
        if (/your-special-page/.test(item.url)) {
          item.changefreq = 'daily';
          item.lastmod = new Date();
          item.priority = 0.9;
        }
        return item;
      },
    }),
  ],
});

i18n

To localize a sitemap, pass an object to this i18n option.

This object has two required properties:

defaultLocale: String. Its value must exist as one of locales keys.
locales: Record<String, String>, key/value - pairs. The key is used to look for a locale part in a page path. The value is a language attribute, only English alphabet and hyphen allowed.

Examples

The official Astro website uses Astro Sitemap to generate its sitemap.
The integrations playground template comes with Astro Sitemap installed. Try adding a route and building the project!
