The crawler

In many projects, you first "crawl" the web or one specific website to discover URLs which then you definitely pass on to your scraper.
The scraper
A web scraper is a specialised software designed to accurately and quickly extract data from a web page. Web scrapers fluctuate widely in design and complicatedity, depending on the project. An vital part of every scraper is the data locators (or selectors) that are used to search out the data that you just want to extract from the HTML file - usually, XPath, CSS selectors, regex, or a mix of them is applied.
The web data scraping process
Should you do it yourself
This is what a general DIY web scraping process looks like:
Establish the target website
Acquire URLs of the pages where you need 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 in the HTML
Save the data in a JSON or CSV file or some other structured format
Simple sufficient, proper? It is! In case you just have a small project. However sadly, there are quite a number of challenges you should tackle if you want data at scale. For example, maintaining the scraper if the website structure modifications, managing proxies, executing javascript, or working round antibots.
