The components are pluggable and can be changed, if you’re familiar with the Twisted Application Framework which Scrapyd is implemented items once they have been extracted (or scraped) by the spiders. Typical tasks include cleansing, validation and persistence (like storing the item in a database). For more information see Item Pipeline.
