Boost Your Scrapy Debugging: 4 Handy Tips for Faster Development

After fixing bugs in a Scrapy spider, you can start writing the crawling logic. The article presents four useful tips to simplify spider manipulation and debugging.

1. Create a main.py file for direct debugging in PyCharm

Place a main.py file in the same directory as scrapy.cfg. This script can launch the entire Scrapy project, allowing you to run the spider without using the command line.

The execute function inside the script calls Scrapy’s internal runner; it automatically determines the project’s parent directory, saving you from manually copying paths and making the project portable.

2. Use PyCharm’s Debugger to speed up development

Set breakpoints by clicking the left margin of the code line (the red dot). Then right‑click main.py and choose Debug ‘main’ .

When the debugger runs, Scrapy’s output appears in the console, with results highlighted in green for easy reading.

To stop the debugging session, click the Run menu in PyCharm and select Stop ‘main’ .

After stopping, PyCharm returns to its normal interface.

These two tips help you run and debug Scrapy projects more efficiently; the article promises additional debugging methods in a future post.
