How to add an RSS feed to your Astro site
Learn how to set up a fully functional RSS feed in Astro. Perfect for blogs and content websites looking to boost discoverability and support subscriptions.
Want readers to subscribe to your blog via RSS? Astro makes it easy with the @astrojs/rss package. With just a few lines of code, you can generate a fast, standards-compliant RSS feed that keeps your audience in the loop.
1. Install @astrojs/rss
First, add the package to your project:
pnpm add @astrojs/rssMake sure your astro.config.mjs includes a site URL — it’s required to generate full links:
// astro.config.mjs
import { defineConfig } from 'astro/config';
export default defineConfig({
site: 'https://example.com', // replace with your site
});2. Create the RSS feed file
Create a new file in src/pages/ called rss.xml.js (or feed.xml.js). This will be your feed endpoint.
// src/pages/rss.xml.js
import rss from '@astrojs/rss';
import { getCollection } from 'astro:content';
export async function GET(context) {
const posts = await getCollection('blog');
return rss({
title: 'My Blog',
description: 'Latest posts from my Astro site',
site: context.site,
items: posts.map((post) => ({
title: post.data.title,
description: post.data.description,
pubDate: post.data.pubDate,
link: `/blog/${post.id}/`,
})),
});
}Your feed will now be available at /rss.xml.
3. Enable autodiscovery
Add this tag inside your <head> to make it easier for browsers and RSS readers to find your feed:
<link
rel="alternate"
type="application/rss+xml"
title="My Blog Feed"
href={new URL('rss.xml', Astro.site)}
/>4. Optional: Use RSS schema for validation
If you want to enforce correct frontmatter for all blog posts, use rssSchema in your content.config.ts:
// src/content/config.ts
import { defineCollection } from 'astro:content';
import { rssSchema } from '@astrojs/rss';
const blog = defineCollection({
schema: rssSchema,
});
export const collections = { blog };Already built into our blazing-fast themes
