In many projects, you first “crawl” the web or one specific website to discover URLs which then you pass on to your scraper.

The scraper

A web scraper is a specialized tool designed to accurately and quickly extract data from a web page. Web scrapers vary widely in design and complexity, relying on the project. An vital part of each scraper is the data locators (or selectors) which might be used to find the data that you wish to extract from the HTML file – often, XPath, CSS selectors, regex, or a combination of them is applied.

The web data scraping process

In the event you do it your self

This is what a basic DIY web scraping process looks like:

Identify the goal website

Acquire URLs of the pages the place you need to extract data from

Make a request to these URLs to get the HTML of the page

Use locators to search out the data within the HTML

Save the data in a JSON or CSV file or some other structured format

Simple enough, proper? It’s! When you just have a small project. However sadly, there are quite a number of challenges it’s worthwhile to tackle if you want data at scale. For example, maintaining the scraper if the website layout adjustments, managing proxies, executing javascript, or working around antibots.
