How To Crawl a Site with Scrapy in December, 2023
Whether you are looking to obtain data from a website, track changes on the internet, or use a website API, website crawlers are a great way to get the data you need. While they have many components, crawlers fundamentally use a simple process: download the raw data, process and extract it, and, if desired, store the data in a file or database. There are many ways to do this, and many languages you can build your spider or crawler in.
Scrapy is a Python framework for building website crawlers. Scapy provides many of the functions required for downloading websites and other content on the internet, making the development process quicker and less programming-intensive. These tutorials use custom Python scripts in conjunction with Scrapy to build crawlers and web spiders.
