How to scrape product prices from Idealo.co.uk using JavaScript?
Scraping product prices from Idealo.co.uk using JavaScript allows you to collect data on electronics, appliances, and other consumer goods. Idealo is a price comparison site, making it a valuable resource for analyzing trends and identifying deals. Using Node.js with Puppeteer, you can automate browser interactions to handle dynamic content and extract relevant product details such as names, prices, and ratings. The process begins with inspecting the page structure to identify the elements containing the desired data points.
Pagination is critical for accessing all products across multiple pages, ensuring a complete dataset. Introducing delays between requests reduces detection risks and mimics human browsing behavior. Once collected, the data can be stored in structured formats for analysis. Below is an example Node.js script for scraping Idealo.const puppeteer = require('puppeteer'); (async () => { const browser = await puppeteer.launch({ headless: true }); const page = await browser.newPage(); const url = 'https://www.idealo.co.uk/'; await page.goto(url, { waitUntil: 'networkidle2' }); const products = await page.evaluate(() => { const productList = []; const items = document.querySelectorAll('.product-card'); items.forEach(item => { const name = item.querySelector('.product-title')?.textContent.trim() || 'Name not available'; const price = item.querySelector('.product-price')?.textContent.trim() || 'Price not available'; productList.push({ name, price }); }); return productList; }); console.log(products); await browser.close(); })();This script extracts product names and prices from Idealo’s product pages. Pagination handling ensures that all listings are captured. Adding random delays between requests prevents detection, making the scraping process smoother.

Handling pagination is essential for scraping Idealo.co.uk effectively, as products are often spread across multiple pages. Automating navigation through “Next” buttons ensures that all listings are captured for a comprehensive dataset. Adding random delays between requests reduces detection risks and ensures smooth operation. This functionality is particularly useful for tracking pricing trends across various categories. Proper pagination handling makes the scraper more efficient and reliable.

Error handling ensures that the scraper remains functional even when Idealo updates its layout. Missing elements such as product prices or names can cause issues, but adding conditional checks ensures smooth operation. Logging skipped entries provides valuable insights into potential improvements for the scraper. Regular updates to the script help maintain its effectiveness despite changes to Idealo’s website. These practices improve the scraper’s reliability and usability over time.
