Create a full-featured price tracking application that monitors products across multiple stores.
Plan your product database, scraping schedule, and alert system.
Create scheduled tasks to scrape product pages.
async function trackPrice(url: string, selector: string) {
const result = await client.scrape({ url, extract: { price: selector } });
return parseFloat(result.scraped_content.price.replace(/[^0-9.]/g, ''));
}Save each price check to track changes over time.
Send alerts when prices drop below target thresholds.
