In this tutorial, we will walk you through the process of building a news aggregator platform using Express.js and integrating it with RSS feeds. A news aggregator collects and displays news articles from different sources and presents them in one central location.

Prerequisites

Before getting started, make sure you have the following tools installed:

• Node.js and npm
• Express.js

Creating the Express.js Application

To begin, let’s create a new Express.js application:

npm init -y
npm install express

Next, let’s set up our Express.js server in app.js:

const express = require('express');
const app = express();
const PORT = 3000;

app.get('/', (req, res) => {
  res.send('Hello World!');
});

app.listen(PORT, () => {
  console.log(`Server is running on port ${PORT}`);
});

Now, if you run node app.js and navigate to http://localhost:3000, you should see “Hello World!” displayed in your browser.

Integrating RSS Feeds

To integrate RSS feeds into our news aggregator platform, we need to use a package called rss-parser. Let’s install it:

npm install rss-parser

Next, let’s modify our app.js file to retrieve and display RSS feed data:

const express = require('express');
const app = express();
const PORT = 3000;

const Parser = require('rss-parser');
const parser = new Parser();

app.get('/', async (req, res) => {
  const feed = await parser.parseURL('https://example.com/rss-feed-url');
  res.send(feed.items);
});

app.listen(PORT, () => {
  console.log(`Server is running on port ${PORT}`);
});

In the code above, replace 'https://example.com/rss-feed-url' with the actual RSS feed URL you want to integrate.

Now, when you navigate to http://localhost:3000, you should see the parsed RSS feed data displayed as a JSON response.

Further Customizations

You can further customize the news aggregator platform by adding features like pagination, filtering by category or source, and user authentication. Additionally, you can enhance the frontend by using a templating engine like Handlebars or integrating a frontend framework like React.

Conclusion

In this tutorial, we learned how to build a news aggregator platform using Express.js and integrating it with RSS feeds. This platform can serve as a centralized hub for displaying news articles from various sources. With further enhancements and customizations, you can create a robust and personalized news aggregation experience for your users.
