信息

The following is the complete skill definition that Hermes loads when this skill is triggered. This is what the agent sees as instructions when the skill is active.

Scrapling

Scrapling is a web scraping framework with anti-bot bypass, stealth browser automation, and a spider framework. It provides three fetching strategies (HTTP, dynamic JS, stealth/Cloudflare) and a full CLI.

This skill is for educational and research purposes only. Users must comply with local/international data scraping laws and respect website Terms of Service.

When to Use​

  • Scraping static HTML pages (faster than browser tools)
  • Scraping JS-rendered pages that need a real browser
  • Bypassing Cloudflare Turnstile or bot detection
  • Crawling multiple pages with a spider
  • When the built-in web_extract tool does not return the data you need

Installation​

pip install "scrapling[all]"
scrapling install

Minimal install (HTTP only, no browser):

pip install scrapling

With browser automation only:

pip install "scrapling[fetchers]"
scrapling install

Quick Reference​

ApproachClassUse When
HTTPFetcher / FetcherSessionStatic pages, APIs, fast bulk requests
DynamicDynamicFetcher / DynamicSessionJS-rendered content, SPAs
StealthStealthyFetcher / StealthySessionCloudflare, anti-bot protected sites
SpiderSpiderMulti-page crawling with link following

CLI Usage​

Extract Static Page​

scrapling extract get 'https://example.com' output.md

With CSS selector and browser impersonation:

scrapling extract get 'https://example.com' output.md \
  --css-selector '.content' \
  --impersonate 'chrome'

Extract JS-Rendered Page​

scrapling extract fetch 'https://example.com' output.md \
  --css-selector '.dynamic-content' \
  --disable-resources \
  --network-idle

Extract Cloudflare-Protected Page​

scrapling extract stealthy-fetch 'https://protected-site.com' output.html \
  --solve-cloudflare \
  --block-webrtc \
  --hide-canvas

POST Request​

scrapling extract post 'https://example.com/api' output.json \
  --json '{"query": "search term"}'

Output Formats​

The output format is determined by the file extension:

  • .html -- raw HTML
  • .md -- converted to Markdown
  • .txt -- plain text
  • .json / .jsonl -- JSON

Python: HTTP Scraping​

Single Request​

from scrapling.fetchers import Fetcher

page = Fetcher.get('https://quotes.toscrape.com/')
quotes = page.css('.quote .text::text').getall()
for q in quotes:
    print(q)

Session (Persistent Cookies)​

from scrapling.fetchers import FetcherSession

with FetcherSession(impersonate='chrome') as session:
    page = session.get('https://example.com/', stealthy_headers=True)
    links = page.css('a::attr(href)').getall()
    for link in links[:5]:
        sub = session.get(link)
        print(sub.css('h1::text').get())

POST / PUT / DELETE​

page = Fetcher.post('https://api.example.com/data', json={"key": "value"})
page = Fetcher.put('https://api.example.com/item/1', data={"name": "updated"})
page = Fetcher.delete('https://api.example.com/item/1')

With Proxy​

page = Fetcher.get('https://example.com', proxy='http://user:pass@proxy:8080')

Python: Dynamic Pages (JS-Rendered)​

For pages that require JavaScript execution (SPAs, lazy-loaded content):

from scrapling.fetchers import DynamicFetcher

page = DynamicFetcher.fetch('https://example.com', headless=True)
data = page.css('.js-loaded-content::text').getall()

Wait for Specific Element​

page = DynamicFetcher.fetch(
    'https://example.com',
    wait_selector=('.results', 'visible'),
    network_idle=True,
)

Disable Resources for Speed​

Blocks fonts, images, media, stylesheets (~25% faster):

from scrapling.fetchers import DynamicSession

with DynamicSession(headless=True, disable_resources=True, network_idle=True) as session:
    page = session.fetch('https://example.com')
    items = page.css('.item::text').getall()

Custom Page Automation​

from playwright.sync_api import Page
from scrapling.fetchers import DynamicFetcher

def scroll_and_click(page: Page):
    page.mouse.wheel(0, 3000)
    page.wait_for_timeout(1000)
    page.click('button.load-more')
    page.wait_for_selector('.extra-results')

page = DynamicFetcher.fetch('https://example.com', page_action=scroll_and_click)
results = page.css('.extra-results .item::text').getall()

Python: Stealth Mode (Anti-Bot Bypass)​

For Cloudflare-protected or heavily fingerprinted sites:

from scrapling.fetchers import StealthyFetcher

page = StealthyFetcher.fetch(
    'https://protected-site.com',
    headless=True,
    solve_cloudflare=True,
    block_webrtc=True,
    hide_canvas=True,
)
content = page.css('.protected-content::text').getall()

Stealth Session​

from scrapling.fetchers import StealthySession

with StealthySession(headless=True, solve_cloudflare=True) as session:
    page1 = session.fetch('https://protected-site.com/page1')
    page2 = session.fetch('https://protected-site.com/page2')

Element Selection​

All fetchers return a Selector object with these methods:

CSS Selectors​

page.css('h1::text').get()              # First h1 text
page.css('a::attr(href)').getall()      # All link hrefs
page.css('.quote .text::text').getall() # Nested selection

XPath​

page.xpath('//div[@class="content"]/text()').getall()
page.xpath('//a/@href').getall()

Find Methods​

page.find_all('div', class_='quote')       # By tag + attribute
page.find_by_text('Read more', tag='a')    # By text content
page.find_by_regex(r'\$\d+\.\d{2}')       # By regex pattern

Similar Elements​

Find elements with similar structure (useful for product listings, etc.):

first_product = page.css('.product')[0]
all_similar = first_product.find_similar()
el = page.css('.target')[0]
el.parent                # Parent element
el.children              # Child elements
el.next_sibling          # Next sibling
el.prev_sibling          # Previous sibling

Python: Spider Framework​

For multi-page crawling with link following:

from scrapling.spiders import Spider, Request, Response

class QuotesSpider(Spider):
    name = "quotes"
    start_urls = ["https://quotes.toscrape.com/"]
    concurrent_requests = 10
    download_delay = 1

    async def parse(self, response: Response):
        for quote in response.css('.quote'):
            yield {
                "text": quote.css('.text::text').get(),
                "author": quote.css('.author::text').get(),
                "tags": quote.css('.tag::text').getall(),
            }

        next_page = response.css('.next a::attr(href)').get()
        if next_page:
            yield response.follow(next_page)

result = QuotesSpider().start()
print(f"Scraped {len(result.items)} quotes")
result.items.to_json("quotes.json")

Multi-Session Spider​

Route requests to different fetcher types:

from scrapling.fetchers import FetcherSession, AsyncStealthySession

class SmartSpider(Spider):
    name = "smart"
    start_urls = ["https://example.com/"]

    def configure_sessions(self, manager):
        manager.add("fast", FetcherSession(impersonate="chrome"))
        manager.add("stealth", AsyncStealthySession(headless=True), lazy=True)

    async def parse(self, response: Response):
        for link in response.css('a::attr(href)').getall():
            if "protected" in link:
                yield Request(link, sid="stealth")
            else:
                yield Request(link, sid="fast", callback=self.parse)

Pause/Resume Crawling​

spider = QuotesSpider(crawldir="./crawl_checkpoint")
spider.start()  # Ctrl+C to pause, re-run to resume from checkpoint

Pitfalls​

  • Browser install required: run scrapling install after pip install -- without it, DynamicFetcher and StealthyFetcher will fail
  • Timeouts: DynamicFetcher/StealthyFetcher timeout is in milliseconds (default 30000), Fetcher timeout is in seconds
  • Cloudflare bypass: solve_cloudflare=True adds 5-15 seconds to fetch time -- only enable when needed
  • Resource usage: StealthyFetcher runs a real browser -- limit concurrent usage
  • Legal: always check robots.txt and website ToS before scraping. This library is for educational and research purposes
  • Python version: requires Python 3.10+
