How to scrape product details from Petco.com using JavaScript?
Scraping product details from Petco.com using JavaScript allows you to collect data such as product names, prices, and availability. Using Node.js with Puppeteer, you can automate browser interactions to handle dynamic content and extract the necessary information. Below is a sample script for scraping product data from Petco.
const puppeteer = require('puppeteer'); (async () => { const browser = await puppeteer.launch({ headless: true }); const page = await browser.newPage(); const url = 'https://www.petco.com/shop/en/petcostore/category/dog'; 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-name')?.textContent.trim() || 'Name not available'; const price = item.querySelector('.product-price')?.textContent.trim() || 'Price not available'; const availability = item.querySelector('.availability')?.textContent.trim() || 'Availability not available'; productList.push({ name, price, availability }); }); return productList; }); console.log(products); await browser.close(); })();This script navigates to Petco’s dog category page, waits for the content to load, and extracts product names, prices, and availability. Pagination can be added to scrape additional product listings by automating navigation through “Next” buttons. Randomizing request timing helps avoid detection.

Handling pagination ensures the scraper collects data from all available products on Petco. Products are often distributed across multiple pages, and automating navigation through “Next” buttons allows for a complete dataset. Random delays between page requests mimic real user behavior and reduce the likelihood of detection. Pagination handling ensures comprehensive data collection for better analysis.

Error handling improves the reliability of the scraper by addressing missing or incomplete elements. If some products lack prices or availability, the scraper should log these cases without crashing. Adding checks for null values ensures that the script continues functioning effectively. Regular updates to the scraper keep it functional despite changes to Petco’s layout. Proper error handling ensures smooth scraping sessions.
