Dude (dude uncomplicated data extraction) is a very simple framework for writing web scrapers using Python decorators. The design, inspired by Flask, was to easily build a web scraper in just a few lines of code. Dude has an easy-to-learn syntax.

The simplest web scraper will look like this:

from dude import select


@select(css="a")
def get_link(element):
    return {"url": element.get_attribute("href")}

dude supports multiple parser backends: - playwright
- lxml
- parsel - beautifulsoup - pyppeteer - selenium

ScrapydWeb is a web-based management tool for the Scrapyd service. It is built using the Python Flask framework and allows you to easily manage and monitor your Scrapy spider projects through a web interface.

ScrapydWeb allows you to view the status of your running spiders, view the logs of completed spiders, schedule new spider runs, and manage spider settings and configurations.

ScrapydWeb provides a simple way to manage your scraping tasks and allows you to schedule and run multiple spiders simultaneously. It also provides a user-friendly web interface that makes it easy to view the status of your spiders and monitor their progress.

You can install the package via pip by running pip install scrapydweb and then you can run the package by running scrapydweb command in your command prompt.

It will start a web server that you can access through your web browser at http://localhost:6800/ You will need to have Scrapyd running in order to use ScrapydWeb, Scrapyd is a service for running Scrapy spiders, it allows you to schedule spiders to run at regular intervals and also allows you to run spiders on remote machines.

Example Use


from dude import select

"""
This example demonstrates how to use Parsel + async HTTPX
To access an attribute, use:
    selector.attrib["href"]
You can also access an attribute using the ::attr(name) pseudo-element, for example "a::attr(href)", then:
    selector.get()
To get the text, use ::text pseudo-element, then:
    selector.get()
"""


@select(css="a.url", priority=2)
async def result_url(selector):
    return {"url": selector.attrib["href"]}


# Option to get url using ::attr(name) pseudo-element
@select(css="a.url::attr(href)", priority=2)
async def result_url2(selector):
    return {"url2": selector.get()}


@select(css=".title::text", priority=1)
async def result_title(selector):
    return {"title": selector.get()}


@select(css=".description::text", priority=0)
async def result_description(selector):
    return {"description": selector.get()}


if __name__ == "__main__":
    import dude

    dude.run(urls=["https://dude.ron.sh"], parser="parsel")
