Node.js & Privacy Pass application for Cloudflare scrape solution

them are among the top 100K website worldwide. As Cloudflare
establishes itself as the norm regarding service protection, chances are, the site you want to scrape is more likely to use it than not.

When it comes to scrapping websites, captchas and other type of
protections were always the main obstacle in providing reliable data collection solutions. And most often this would lead to consider bypass services which aren’t always free.

Python, Selenium for custom browser automation scraper

Recently we’ve got the tricky website, its data being of dynamic nature. Yet we’ve applied the modern day scraping tools to fetch data. We’ve develop an effective Python scraper using Selenium library for browser automation.

About the project

We were asked to have a look at a retailer website.

And our task was to gather data on 210 products’ availability in 945 shops. The scrape resulted in about 200K data entries in a CSV format. Moreover, every line contained information about name, link, brand, store and the availability of a product. Below you can familiarise yourself with a small data sample we were able to gather.

CodeStar connection full working policy at AWS

The original AWSCodeStarFullAccess policy is full [to provide access to AWS CodeStar via the AWS Management Console] yet it still does not grant enough access to create a Code connection for IAM at CodePipeline. So we had to manage to create a custom policy based on AWS tutorial suggestions.
