How to add an RSS feed to your SvelteKit app

Published on May 7, 2024

Install the Feed npm package to your project.

npm i feed

Create a directory (folder) named rss.xml in your routes directory.
- The name doesn't matter. As long is it ends with .xml.
Create a +server.ts file inside src/routes/rss.xml directory.
In +server.ts file, export an async function named GET. This will expose an endpoint that responds with the rss.xml file.

export async function GET() {
	// ...
}

Create a Feed instance. I think most of these properties are self explanatory.

import { Feed } from 'feed';
 
export async function GET() {
	const feed = new Feed({
		title: 'Gebna blog',
		description: "Gebna, GebnaTorky, or Bahaa Zidan's Blog",
		id: 'https://gebna.gg/',
		link: 'https://gebna.gg/',
		language: 'en', // optional, used only in RSS 2.0, possible values: http://www.w3.org/TR/REC-html40/struct/dirlang.html#langcodes
		favicon: 'https://gebna.gg/favicon.ico',
		copyright: `Copyright ${new Date().getFullYear().toString()}, Bahaa Zidan / Gebna`,
		generator: '🍉', // optional, default = 'Feed for Node.js'
		feedLinks: {
			rss: 'https://gebna.gg/rss.xml',
		},
		author: {
			name: 'Gebna / Bahaa Zidan',
			email: 'gebnatorky@gmail.com',
			link: 'https://gebna.gg/whoami',
		},
		ttl: 60,
	});
}

Get the array of posts, articles, videos, or whatever you want to list in your feed. Here I implemented a getArticles function that returns an array of articles.

import { getArticles } from '$lib';

Loop over the array of articles, add each article to the feed.

// ...
 
export async function GET() {
	// ...
	const articles = getArticles();
	for (const article of articles) {
		feed.addItem({
			title: article.title,
			description: article.description,
			content: `<p>${article.description}</p> <div style="margin-top: 50px; font-style: italic;"> <strong><a href="https://gebna.gg${article.path}">Keep reading</a>.</strong> </div> <br /> <br />`,
			link: `https://gebna.gg${article.path}`,
			author: [
				{
					name: 'Gebna / Bahaa Zidan',
					email: 'gebnatorky@gmail.com',
					link: 'https://gebna.gg/whoami',
				},
			],
			date: new Date(article.publishDate),
		});
	}
}

Finally, return a response with body feed.rss2(). Don't forget the content type.

return new Response(feed.rss2(), {
	headers: {
		'Content-Type': 'application/xml; charset=utf-8',
	},
});

Here's the full src/routes/rss.xml/+server.ts file:

import { Feed } from 'feed';
 
import { getArticles } from '$lib';
 
export async function GET() {
	const feed = new Feed({
		title: 'Gebna blog',
		description: "Gebna, GebnaTorky, or Bahaa Zidan's Blog",
		id: 'https://gebna.gg/',
		link: 'https://gebna.gg/',
		language: 'en', // optional, used only in RSS 2.0, possible values: http://www.w3.org/TR/REC-html40/struct/dirlang.html#langcodes
		favicon: 'https://gebna.gg/favicon.ico',
		copyright: `Copyright ${new Date().getFullYear().toString()}, Bahaa Zidan / Gebna`,
		generator: '🍉', // optional, default = 'Feed for Node.js'
		feedLinks: {
			rss: 'https://gebna.gg/rss.xml',
		},
		author: {
			name: 'Gebna / Bahaa Zidan',
			email: 'gebnatorky@gmail.com',
			link: 'https://gebna.gg/whoami',
		},
		ttl: 60,
	});
	const articles = getArticles();
 
	for (const article of articles) {
		feed.addItem({
			title: article.title,
			description: article.description,
			content: `<p>${article.description}</p> <div style="margin-top: 50px; font-style: italic;"> <strong><a href="https://gebna.gg${article.path}">Keep reading</a>.</strong> </div> <br /> <br />`,
			link: `https://gebna.gg${article.path}`,
			author: [
				{
					name: 'Gebna / Bahaa Zidan',
					email: 'gebnatorky@gmail.com',
					link: 'https://gebna.gg/whoami',
				},
			],
			date: new Date(article.publishDate),
		});
	}
 
	return new Response(feed.rss2(), {
		headers: {
			'Content-Type': 'application/xml; charset=utf-8',
		},
	});
}
