microwler 0.1.8

A micro-framework for asynchronous deep crawls and web scraping written in Python

Microwler is a micro-framework for asynchronous web crawling and scraping implemented in Python. It is designed for deep crawls, i.e. retrieving every page of a specific website.

Core features:

• define crawlers in a single file using a declarative approach
• control your crawlers via CLI, Python scripts or HTTP
• cache your results on disk
• use incremental crawling mode (only crawl new pages)
• use pre-built selectors to scrape common data, i.e. <meta> or <title>
• easily define custom selectors using XPath & CSS
• define "transformers" to manipulate scraped data after crawling
• export data with pre-built plugins or build your own
• use the built-in web service (API + Frontend)

If you're familiar with Microwler, you can install the package from PyPI using: pip install microwler.

Inspiration

Many concepts were inspired by experience with Scrapy, the industry standard for web crawling with Python. The idea was to design a very minimalistic framework for analysing specific websites. We tried to focus on making things as simple as possible for developers. With Microwler, you can build crawlers and extract relevant data in a breeze - and in a single file.
