I frequently visit numerous news aggregator pages, which are fantastic because they allow me to find the latest .NET articles from various sites on a single page.

However, how challenging could it be to construct one of these sites? It turns out it’s pretty easy. I managed to build one of them in a couple of free afternoons.

You can visit it by going to:

The site is fully automated; I don’t need to lift a finger to update the content on it. Every few hours, it fetches the latest news from a series of RSS feeds and updates the site autonomously.

In this post, I will show you how I built it.

What I have built?

The site utilizes the following technologies:

  • The site is built using Hugo. Hugo is one of the most popular open-source static site generators.
  • A Python script that fetches the latest news from a series of RSS feeds and programmatically updates the site content.
  • A GitHub Action that runs the Python script.

Below is a diagram illustrating the entire process.


As you can see, the process is incredibly simple, but there are a couple more components worth mentioning:

  • Another Python script removes news older than one week from the site, preventing uncontrolled growth of the site. This script is called by the same GitHub Action.
  • A second GitHub Action is responsible for publishing the Hugo site. The first GitHub Action (as shown in the diagram above) fetches the latest news and updates the site content, but after updating it, it needs to be deployed somewhere. In this case, we’re deploying it to another GitHub repository with GitHub Pages enabled, utilizing this secondary GitHub Action.
