The web data scraping process
In the event you do it yourself
This is what a common DIY web scraping process looks like:
Determine the target website
Collect 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 within the HTML
Save the data in a JSON or CSV file or some other structured format
Simple sufficient, right? It’s! In the event you just have a small project. But sadly, there are quite a couple of challenges you’ll want to tackle in the event you need data at scale.
