https://github.com/paulpierre

📝 Overview
This is a multithreaded web crawler that crawls a website and creates markdown files for each page.
It was primarily created for large language model document parsing to simplify chunking and processing of large documents for RAG use cases.
Markdown by nature is human readable and maintains document structure while keeping a small footprint.
Features include
- 🧵 Threading support for faster crawling
- ⏯️ Continue scraping where you left off
- ⏬ Set the max depth of children you wish to crawl
- 📄 Support for tables, images, etc.
- ✅ Validates URLs, HTML, filepaths
- ⚙️ Configure list of valid base paths or base domains
- 🍲 Uses BeautifulSoup to parse HTML
- 🪵 Verbose logging option
- 👩💻 Ready-to-go CLI interface
🚀 Get started
If you wish to simply use it in the CLI, you can run the following command:
Install the package
pip install markdown-crawler
Execute the CLI
markdown-crawler -t 5 -d 3 -b ./markdown https://en.wikipedia.org/wiki/Morty_Smith
To run from the github repo, once you have it checked out:
pip install .
markdown-crawler -t 5 -d 3 -b ./markdown https://en.wikipedia.org/wiki/Morty_Smith
Or use the library in your own code:
from markdown_crawler import md_crawl
url = 'https://en.wikipedia.org/wiki/Morty_Smith'
md_crawl(url, max_depth=3, num_threads=5, base_path='markdown')
⚠️ Requirements
- Python 3.x
- BeautifulSoup4
- requests
🔍 Usage
The following arguments are supported
usage: markdown-crawler [-h] [--max-depth MAX_DEPTH] [--num-threads NUM_THREADS] [--base-path BASE_PATH] [--debug DEBUG]
[--target-content TARGET_CONTENT] [--target-links TARGET_LINKS] [--valid-paths VALID_PATHS]
[--domain-match DOMAIN_MATCH] [--base-path-match BASE_PATH_MATCH]
[--links ]
base-url
📝 Example
Take a look at example.py for an example
implementation of the library. In this configuration we set:
max_depth
to 3. We will crawl the base URL and 3 levels of childrennum_threads
to 5. We will use 5 parallel(ish) threads to crawl the websitebase_dir
to markdown
. We will save the markdown files in the markdown
directoryvalid_paths
an array of valid relative URL paths. We will only crawl pages that are in this list and base pathtarget_content
to div#content
. We will only crawl pages that have this HTML element using CSS target selectors. You can provide multiple and it will concatenate the resultsis_domain_match
to False
. We will only crawl pages that are in the same domain as the base URLis_base_path_match
to False
. We will include all URLs in the same domain, even if they don't begin with the base urlis_debug
to True. We will print out verbose logging
And when we run it we can view the progress
![cli](https://github.com/paulpierre/markdown-crawler/blob/main/img/ss_crawler.png?raw=true)
We can see the progress of our files in the markdown
directory locally
![md](https://github.com/paulpierre/markdown-crawler/blob/main/img/ss_dir.png?raw=true)
And we can see the contents of the HTML converted to markdown
