The scraper
A web scraper is a specialized software designed to accurately and quickly extract data from a web page. Web scrapers range widely in design and complicatedity, relying on the project.

The web data scraping process
In the event you do it your self
This is what a common DIY web scraping process looks like:
Establish the goal website
Gather URLs of the pages where you wish to extract data from
Make a request to those URLs to get the HTML of the web page
Use locators to seek out the data within the HTML
Save the data in a JSON or CSV file or some other structured format
Simple enough, proper? It is! When you just have a small project. However unfortunately, there are quite a couple of challenges that you must tackle in case you need data at scale. For example, maintaining the scraper if the website layout adjustments, managing proxies, executing javascript, or working round antibots.
