Scrapy extensions are components that add functionality to your Scrapy project. They can be used to modify the behavior of the Scrapy engine.
Can you give me an example of a common extension?
Sure! A common extension is the TelnetConsole
, which allows you to interact with your Scrapy spider via a Telnet interface.
How do I enable the TelnetConsole extension?
You can enable it by adding TELNETCONSOLE_ENABLED = True
in your Scrapy settings file.
Are there any other useful extensions I should know about?
