Quick Usage

You can quickly generate a RSS 2.0 output with the following lines of code:

import { Feed } from "rivu";

const feed = new Feed({
  title: "Somraj's Blog",
  link: "https://jarmos.dev/rss.xml",
  description:
    "The personal blog (and digital garden) maintained by Somraj Saha (aka Jarmos).",
  language: "en-US",
  items: [
    {
      title: "Example Blog",
      description: "Lorem Ipsum",
      pubDate: new Date("2025-10-10"),
    },
  ],
});

feed.generate();

This should print a full RSS 2.0 feed as a string like this:

<?xml version="1.0" encoding="UTF-8"?>
<rss version="2.0">
  <channel>
    ...
  </channel>
</rss>
