How to Get the Finest Deals Using Web Scraping on a Raspberry Pi Device?

Have you ever wished to know about discounted prices beforehand? This blog talks about creating a tool using web scraping techniques on a Raspberry Pi device to identify the best deals. You can easily make this device at home in just 10 minutes.

Fundamentals

For the purpose of our use cases, a laptop or a Raspberry Pi can be used, but we will be using Raspberry Pi as a web scraping server that runs continuously. There are numerous Raspberry Pi projects available online, but most of them require some electrical engineering.

Python 3 is the language of choice for our application. It has a wide range of powerful libraries, and it is easy to get started and create a prototype. Since Python 2 will no longer be supported from January 1st, 2020, we will use Python 3.

Scrapy is among the finest open-source web extraction frameworks available in Python. It is a powerful and incredibly fast tool that is at the core of our set of tools. While new versions have been developed, the core components have remained largely unchanged. We will be using the latest version of Scrapy 2.0.1 on Python 3.6.10 in this article.

To inspect objects and extract HTML tags with ease, a modern browser with developer tools enabled is recommended.

Website

To succeed in web scraping, it's important to choose a site with a high amount of traffic. Some websites that offer discounts and promo codes include SlickDeals, Dealnews, and DealMoon. For the purposes of this blog, we will be using SlickDeals as our chosen website to scrape data. While there will be different components on the HTML to extract, there are no restrictions on choosing a website that aligns with your interests.

Final thought

Great job! Your web scraping program is now up and running 24/7, just as you requested. Whether your aim is to find great deals, freebies, or coupons, our program is working tirelessly in the background to monitor and alert you of the best finds. We hope this blog has given you some insight into web scraping and the potential to build even more advanced programs on a small device like the Raspberry Pi.
