Quickstart

You can just run globy-scraper as a script (no installation needed):

pip3 install -r requirements.txt  # Install dependencies if not already installed
./globy-scraper.py -f wordpress-top50.txt

---

Install the globy-webcrawlers package

You can install the package for development and use with other Globy projects. It's recommended to set up a python virtual environment before installing the package.

pip3 install -e .

Now you can use the package in python:

from globy_webcrawlers.crawler import WebSiteDataCrawler
>>> c = WebSiteDataCrawler()
>>> c.load_urls_from_file("urls.txt")
>>> c.run()

Also, after installing globy-scraper, you can just run it: globy-scraper.py -h

Debugging/inspecting website content

Since the crawler is asynchronous, it can be a bit tricky to debug the responses. To make it easier, you can use the -d flag. This will allow you to inspect the HTML content and any internal objects from the most recent website. Here's an example:

$ ./globy-scraper.py -f wordpress-top50.txt -d

>>> w = crawler.debug_latest_response()
>>> w.url
'https://www.thyroid.org/'
>>> len(w.html_content)
249167
>>> w.get_website_info()

Change the crawler.urls to get the response you want to debug, or the input url list.

Development only

Build and & create python package:

python3 -m build
