📝 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
• ✅ 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]
                  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 children
• num_threads to 5. We will use 5 parallel(ish) threads to crawl the website
• base_dir to markdown. We will save the markdown files in the markdown directory
• valid_paths an array of valid relative URL paths. We will only crawl pages that are in this list and base path
• is_domain_match to False. We will only crawl pages that are in the same domain as the base URL
• is_base_match to False. We will include all URLs in the same domain, even if they don't begin with the base url
• is_debug to True. We will print out verbose logging
  
  

And when we run it we can view the progress

We can see the progress of our files in the markdown directory locally

And we can see the contents of the HTML converted to markdown
