How to scrape product availability from Aldi.co.uk using Go?
Scraping product availability from Aldi.co.uk using Go provides a way to track stock levels, product names, and prices for a wide range of items, including groceries and household essentials. Aldi is a leading supermarket chain, and its website features detailed information about in-store and online products. Using Go, you can send HTTP requests to the website and parse the response to identify data points like availability and pricing. This approach ensures that you can track inventory changes and pricing trends efficiently.
Handling dynamically loaded content can be a challenge, especially for products with fluctuating availability. Introducing logic to refresh and recheck availability ensures accurate data collection. Below is an example Go script for scraping product availability from Aldi.co.uk.package main import ( "fmt" "net/http" "golang.org/x/net/html" ) func main() { url := "https://www.aldi.co.uk/" resp, err := http.Get(url) if err != nil { fmt.Println("Failed to fetch the page") return } defer resp.Body.Close() doc, err := html.Parse(resp.Body) if err != nil { fmt.Println("Failed to parse HTML") return } var parse func(*html.Node) parse = func(node *html.Node) { if node.Type == html.ElementNode && node.Data == "div" { for _, attr := range node.Attr { if attr.Key == "class" && attr.Val == "product-card" { fmt.Println("Product found") } } } for child := node.FirstChild; child != nil; child = child.NextSibling { parse(child) } } parse(doc) }This script identifies product cards on Aldi.co.uk’s product pages. Additional functionality can be added to extract prices, availability statuses, and product descriptions. Handling dynamic content ensures that all relevant data is captured accurately.

A useful addition to the scraper is monitoring Aldi’s “Special Buys” section, which features limited-time products. Tracking these products can provide insights into seasonal trends and demand patterns. Another improvement could involve analyzing how availability fluctuates during peak hours or days. By capturing such trends, you can identify patterns that impact customer purchasing behavior. These features add value to the scraper and make it more versatile.

Adding geo-targeting functionality can help track availability across different Aldi store locations. For example, identifying which products are available in specific regions enables more targeted analysis. Combining this with price tracking adds depth to the dataset and provides a complete view of regional variations. This functionality is especially useful for comparing store-specific promotions. Enhancing the scraper in this way makes it a powerful tool for localized market analysis.
