RSS is over 20 years old. It remains a top way to share news, blogs, and podcasts.
Many developers use heavy frameworks to show RSS feeds. You do not need them. RSS is just XML. Your browser can read XML natively.
You can build a clean, responsive RSS widget using only vanilla JavaScript and CSS.
How it works:
- Use the Fetch API to get the XML data.
- Use DOMParser to turn that XML into a readable document.
- Loop through the items to extract titles, links, and descriptions.
- Render the data into a grid of cards.
A common problem is CORS. If a server blocks your request, the browser stops it. You can fix this by using a proxy like allorigins.win. For professional projects, use a Cloudflare Worker to handle requests.
Key features of this approach:
- No npm installs or external libraries.
- Small file size and fast loading.
- Works with any standard RSS 2.0 feed.
- Easy to add category filters.
You can extend this widget by adding:
- Auto-refresh to keep content current.
- A search bar to find specific posts.
- Local storage to cache data.
- Dark mode support using CSS variables.
Stop reaching for heavy tools when native APIs work perfectly.
