Hi @brave bronze. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

Astro's @astrojs/sitemap integration can generate a sitemap for your Astro project. However, it's important to note that this integration cannot generate sitemap entries for dynamic routes in SSR mode. The sitemap integration will crawl your statically-generated routes and create the sitemap file, including dynamic routes like [...slug] or src/pages/[lang]/[version]/info.astro generated by getStaticPaths().

To use the @astrojs/sitemap integration, you need to install it first. You can use the astro add command to automate the setup or install it manually using your package manager. Here's how you can do it:

# Using npm
npm install @astrojs/sitemap

# Using pnpm
pnpm add @astrojs/sitemap

# Using yarn
yarn add @astrojs/sitemap

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

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

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

The @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:.

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

export default defineConfig({
  // ...
  site: '<https://yourwebsite.com',>
  integrations: [sitemap()],
});

After setting up, build your site for production via the astro build command. You will find both sitemap-index.xml and sitemap-0.xml in the dist/ folder (or your custom output directory if set).

#

However, if you have dynamic routes that are server-side rendered, the current @astrojs/sitemap integration will not be able to generate entries for them. This is due to the fact that dynamic SSR routes are unknown at build time and could potentially be infinite.

For dynamic routes, you might need to manually create a sitemap or use a different approach. Unfortunately, the provided knowledge sources do not provide a specific solution for generating a sitemap for dynamic SSR routes in Astro.

@light pewter I specified i need this to work in SSR. How to make that happen?

Let me check the knowledge base for you. One moment! :books:

To create a dynamic sitemap in Astro using server-side rendering (SSR), you can use Astro's SSR capabilities to fetch data from a database or an API and generate the sitemap dynamically.

Here's a simplified example of how you can do this:

---
// Import your database access methods
import { db, ProjectDetails } from '../api/db';

// Fetch all project details to include in the sitemap
const Projects = await db.select().from(ProjectDetails);

// Function to format date in YYYY-MM-DD format for lastmod tag
function formatDate(date) {
  const d = new Date(date);
  let month = '' + (d.getMonth() + 1),
      day = '' + d.getDate(),
      year = d.getFullYear();

  if (month.length < 2) 
    month = '0' + month;
  if (day.length < 2) 
    day = '0' + day;

  return [year, month, day].join('-');
}

// Set response type to XML
Astro.response.headers.set("Content-Type", "application/xml");
---

<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="<http://www.sitemaps.org/schemas/sitemap/0.9">>
  {Projects.map((project) => (
    <url>
      <loc>{`<https://yourwebsite.com/${project.slug}`}</loc>>
      <lastmod>{formatDate(project.publishDate)}</lastmod>
      <changefreq>weekly</changefreq>
      <priority>0.8</priority>
    </url>
  ))}
</urlset>

In this example, we're using Astro's SSR capabilities to fetch project details from a database, and then we're using this data to generate the sitemap. The Astro.response.headers.set("Content-Type", "application/xml"); line sets the response type to XML, which is the format required for sitemaps.

Please replace '../api/db' with the actual path to your database access methods and '<https://yourwebsite.com/'> with your actual website URL.

This is a simplified example and might need to be adjusted based on your specific use case and database structure.

@light pewter What is this file called? sitemap.xml.astro? sitemap.xml.ts?

light pewterBOT
#

Let me check the knowledge base for you. One moment! :books:

#

The file can be named sitemap.xml.astro. This is because the .astro extension is used for Astro components, which can fetch data server-side and render HTML, just like in the example you provided. The .xml in the filename indicates that the output should be in XML format, which is the format used for sitemaps.

So, in your case, you would create a file named sitemap.xml.astro in your project, and put your Astro code inside this file.
