Hey everyone! I'm curious about the legality of web scraping in the EU, particularly if I'm planning to use the data for a free price comparison app, like showing that a pair of shoes costs 10 EUR at one store and 12 EUR at another. Do I need to know how to scrape data myself, or do larger retailers often provide public APIs? Also, as a frontend developer with no backend experience, what should I learn to create a web scraper? Would Node.js be a good start? Any guidance would be super appreciated, thanks!

Retail APIs can be hit or miss, especially with the rise of bot protections. If you want lasting access to data, be prepared for more complex scraping techniques, because many sites are tough to scrape successfully due to advanced anti-bot measures. Just a heads-up, maintaining scrapers can be quite a hassle!
Quick recap: yes, scraping is legal for public data in the EU, but you should learn about it to understand how APIs work. As a frontend developer, diving into Node.js and libraries like Axios or Cheerio will definitely help you get started with web scraping!
From my experience, as long as you're scraping publicly available documents, you're in the clear legally. Just remember, while data is public, the actual content might still be copyrighted. If you're new to programming, starting with fetching and parsing documents in languages like Python or Node.js is your best bet.
Web scraping in the EU is generally fine for publicly available information, like prices. Just steer clear of scraping personal data and always check each site's terms of service. Also, don't overload their servers; you don't want to get your IP blocked. Be respectful of robots.txt files when scraping!
As long as you're not scraping sites that require authentication and you're careful about request speed, you should be good. Start with simple tools like Python to learn the basics and try something like Reworkd's free tier for AI-driven scraping. It'll help build your skills!
