-
- :param headless: Run the browser in headless/hidden (default), or headful/visible mode.
- :param disable_resources: Drop requests of unnecessary resources for a speed boost. It depends, but it made requests ~25% faster in my tests for some websites.
- Requests dropped are of type `font`, `image`, `media`, `beacon`, `object`, `imageset`, `texttrack`, `websocket`, `csp_report`, and `stylesheet`.
- This can help save your proxy usage but be careful with this option as it makes some websites never finish loading.
- :param useragent: Pass a useragent string to be used. Otherwise the fetcher will generate a real Useragent of the same browser and use it.
- :param cookies: Set cookies for the next request.
- :param network_idle: Wait for the page until there are no network connections for at least 500 ms.
- :param timeout: The timeout in milliseconds that is used in all operations and waits through the page. The default is 30,000
- :param wait: The time (milliseconds) the fetcher will wait after everything finishes before closing the page and returning the ` Response ` object.
- :param page_action: Added for automation. A function that takes the `page` object, does the automation you need, then returns `page` again.
- :param wait_selector: Wait for a specific CSS selector to be in a specific state.
- :param locale: Set the locale for the browser if wanted. The default value is `en-US`.
- :param wait_selector_state: The state to wait for the selector given with `wait_selector`. The default state is `attached`.
- :param stealth: Enables stealth mode, check the documentation to see what stealth mode does currently.
- :param real_chrome: If you have a Chrome browser installed on your device, enable this, and the Fetcher will launch an instance of your browser and use it.
- :param hide_canvas: Add random noise to canvas operations to prevent fingerprinting.
- :param disable_webgl: Disables WebGL and WebGL 2.0 support entirely.
- :param cdp_url: Instead of launching a new browser instance, connect to this CDP URL to control real browsers/NSTBrowser through CDP.
- :param nstbrowser_mode: Enables NSTBrowser mode, it has to be used with the ` cdp_url ` argument, or it will get completely ignored.
- :param google_search: Enabled by default, Scrapling will set the referer header to be as if this request came from a Google search for this website's domain name.
- :param extra_headers: A dictionary of extra headers to add to the request. _The referer set by the `google_search` argument takes priority over the referer set here if used together._
- :param proxy: The proxy to be used with requests, it can be a string or a dictionary with the keys 'server', 'username', and 'password' only.
- :param nstbrowser_config: The config you want to send with requests to the NSTBrowser. If left empty, Scrapling defaults to an optimized NSTBrowser's docker browserless config.
- :param adaptor_arguments: The arguments that will be passed in the end while creating the final Adaptor's class.

+
+ :param headless: Run the browser in headless/hidden (default), virtual screen mode, or headful/visible mode.
+ :param block_images: Prevent the loading of images through Firefox preferences.
+ This can help save your proxy usage but be careful with this option as it makes some websites never finish loading.
+ :param disable_resources: Drop requests of unnecessary resources for a speed boost. It depends, but it made requests ~25% faster in my tests for some websites.
+ Requests dropped are of type `font`, `image`, `media`, `beacon`, `object`, `imageset`, `texttrack`, `websocket`, `csp_report`, and `stylesheet`.
+ This can help save your proxy usage but be careful with this option as it makes some websites never finish loading.
+ :param block_webrtc: Blocks WebRTC entirely.
+ :param cookies: Set cookies for the next request.
+ :param addons: List of Firefox addons to use. Must be paths to extracted addons.
+ :param humanize: Humanize the cursor movement. Takes either True or the MAX duration in seconds of the cursor movement. The cursor typically takes up to 1.5 seconds to move across the window.
+ :param solve_cloudflare: Solves all 3 types of the Cloudflare's Turnstile wait page before returning the response to you.
+ :param allow_webgl: Enabled by default. Disabling WebGL is not recommended as many WAFs now check if WebGL is enabled.
+ :param network_idle: Wait for the page until there are no network connections for at least 500 ms.
+ :param disable_ads: Disabled by default, this installs the `uBlock Origin` addon on the browser if enabled.
+ :param os_randomize: If enabled, Scrapling will randomize the OS fingerprints used. The default is Scrapling matching the fingerprints with the current OS.
+ :param wait: The time (milliseconds) the fetcher will wait after everything finishes before closing the page and returning the ` Response ` object.
+ :param timeout: The timeout in milliseconds that is used in all operations and waits through the page. The default is 30,000
+ :param page_action: Added for automation. A function that takes the `page` object, does the automation you need, then returns `page` again.
+ :param wait_selector: Wait for a specific CSS selector to be in a specific state.
+ :param geoip: Recommended to use with proxies; Automatically use IP's longitude, latitude, timezone, country, locale, and spoof the WebRTC IP address.
+ It will also calculate and spoof the browser's language based on the distribution of language speakers in the target region.
+ :param wait_selector_state: The state to wait for the selector given with `wait_selector`. The default state is `attached`.
+ :param google_search: Enabled by default, Scrapling will set the referer header to be as if this request came from a Google search for this website's domain name.
+ :param extra_headers: A dictionary of extra headers to add to the request. _The referer set by the `google_search` argument takes priority over the referer set here if used together._
+ :param proxy: The proxy to be used with requests, it can be a string or a dictionary with the keys 'server', 'username', and 'password' only.
+ :param max_pages: The maximum number of tabs to be opened at the same time. It will be used in rotation through a PagePool.
+ :param adaptor_arguments: The arguments that will be passed in the end while creating the final Adaptor's class.
+ :param additional_arguments: Additional arguments to be passed to Camoufox as additional settings, and it takes higher priority than Scrapling's settings.

+
+ :param headless: Run the browser in headless/hidden (default), virtual screen mode, or headful/visible mode.
+ :param block_images: Prevent the loading of images through Firefox preferences.
+ This can help save your proxy usage but be careful with this option as it makes some websites never finish loading.
+ :param disable_resources: Drop requests of unnecessary resources for a speed boost. It depends, but it made requests ~25% faster in my tests for some websites.
+ Requests dropped are of type `font`, `image`, `media`, `beacon`, `object`, `imageset`, `texttrack`, `websocket`, `csp_report`, and `stylesheet`.
+ This can help save your proxy usage but be careful with this option as it makes some websites never finish loading.
+ :param block_webrtc: Blocks WebRTC entirely.
+ :param cookies: Set cookies for the next request.
+ :param addons: List of Firefox addons to use. Must be paths to extracted addons.
+ :param humanize: Humanize the cursor movement. Takes either True or the MAX duration in seconds of the cursor movement. The cursor typically takes up to 1.5 seconds to move across the window.
+ :param solve_cloudflare: Solves all 3 types of the Cloudflare's Turnstile wait page before returning the response to you.
+ :param allow_webgl: Enabled by default. Disabling WebGL is not recommended as many WAFs now check if WebGL is enabled.
+ :param network_idle: Wait for the page until there are no network connections for at least 500 ms.
+ :param disable_ads: Disabled by default, this installs the `uBlock Origin` addon on the browser if enabled.
+ :param os_randomize: If enabled, Scrapling will randomize the OS fingerprints used. The default is Scrapling matching the fingerprints with the current OS.
+ :param wait: The time (milliseconds) the fetcher will wait after everything finishes before closing the page and returning the ` Response ` object.
+ :param timeout: The timeout in milliseconds that is used in all operations and waits through the page. The default is 30,000
+ :param page_action: Added for automation. A function that takes the `page` object, does the automation you need, then returns `page` again.
+ :param wait_selector: Wait for a specific CSS selector to be in a specific state.
+ :param geoip: Recommended to use with proxies; Automatically use IP's longitude, latitude, timezone, country, locale, and spoof the WebRTC IP address.
+ It will also calculate and spoof the browser's language based on the distribution of language speakers in the target region.
+ :param wait_selector_state: The state to wait for the selector given with `wait_selector`. The default state is `attached`.
+ :param google_search: Enabled by default, Scrapling will set the referer header to be as if this request came from a Google search for this website's domain name.
+ :param extra_headers: A dictionary of extra headers to add to the request. _The referer set by the `google_search` argument takes priority over the referer set here if used together._
+ :param proxy: The proxy to be used with requests, it can be a string or a dictionary with the keys 'server', 'username', and 'password' only.
+ :param max_pages: The maximum number of tabs to be opened at the same time. It will be used in rotation through a PagePool.
+ :param adaptor_arguments: The arguments that will be passed in the end while creating the final Adaptor's class.
+ :param additional_arguments: Additional arguments to be passed to Camoufox as additional settings, and it takes higher priority than Scrapling's settings.

Subject: [PATCH 082/204] refactor(Fetcher): Fix the issue of caching
impersonation state + Less code duplication
It now creates a session with each request, but at the same time, it's still faster than the fetcher in v0.2.99 by 20% with more features enabled.

## Getting Started
+### Basic Usage
+```python
+from scrapling.fetchers import Fetcher, StealthyFetcher, DynamicFetcher
+from scrapling.fetchers import FetcherSession, StealthySession, DynamicSession
+
+# HTTP requests with session support
+with FetcherSession(impersonate='chrome') as session: # Use latest version of Chrome's TLS fingerprint
+ page = session.get('https://quotes.toscrape.com/', stealthy_headers=True)
+ quotes = page.css('.quote .text::text')
+
+# Or use one-off requests
+page = Fetcher.get('https://quotes.toscrape.com/')
+quotes = page.css('.quote .text::text')
+
+# Advanced stealth mode (Keep the browser open until you finish)
+with StealthySession(headless=True, solve_cloudflare=True) as session:
+ page = session.fetch('https://nopecha.com/demo/cloudflare')
+ data = page.css('#padded_content a')
+
+# Or use one-off request style, it opens the browser for this request, then closes it after finishing
+page = StealthyFetcher.fetch('https://nopecha.com/demo/cloudflare')
+data = page.css('#padded_content a')
+
+# Full browser automation (Keep the browser open until you finish)
+with DynamicSession(headless=True, disable_resources=False, network_idle=True) as session:
+ page = session.fetch('https://quotes.toscrape.com/')
+ data = page.xpath('//span[@class="text"]/text()') # XPath selector if you prefer it
+
+# Or use one-off request style, it opens the browser for this request, then closes it after finishing
+page = DynamicFetcher.fetch('https://quotes.toscrape.com/')
+data = page.css('.quote .text::text')
+```
+
+### Advanced Parsing & Navigation
```python
from scrapling.fetchers import Fetcher
-# Do HTTP GET request to a web page and create a Selector instance
-page = Fetcher.get('https://quotes.toscrape.com/', stealthy_headers=True)
-# Get all text content from all HTML tags in the page except the `script` and `style` tags
-page.get_all_text(ignore_tags=('script', 'style'))
+# Rich element selection and navigation
+page = Fetcher.get('https://quotes.toscrape.com/')
-# Get all quotes elements; any of these methods will return a list of strings directly (TextHandlers)
-quotes = page.css('.quote .text::text') # CSS selector
-quotes = page.xpath('//span[@class="text"]/text()') # XPath
-quotes = page.css('.quote').css('.text::text') # Chained selectors
-quotes = [element.text for element in page.css('.quote .text')] # Slower than bulk query above
-
-# Get the first quote element
-quote = page.css_first('.quote') # same as page.css('.quote').first or page.css('.quote')[0]
-
-# Tired of selectors? Use find_all/find
-# Get all 'div' HTML tags that one of its 'class' values is 'quote'
-quotes = page.find_all('div', {'class': 'quote'})
+# Get quotes with multiple selection methods
+quotes = page.css('.quote') # CSS selector
+quotes = page.xpath('//div[@class="quote"]') # XPath
+quotes = page.find_all('div', {'class': 'quote'}) # BeautifulSoup-style
# Same as
quotes = page.find_all('div', class_='quote')
quotes = page.find_all(['div'], class_='quote')
quotes = page.find_all(class_='quote') # and so on...
+# Find element by text content
+quotes = page.find_by_text('quote', tag='div')
-# Working with elements
-quote.html_content # Get the Inner HTML of this element
-quote.prettify() # Prettified version of Inner HTML above
-quote.attrib # Get that element's attributes
-quote.path # DOM path to element (List of all ancestors from tag till the element itself)
+# Advanced navigation
+first_quote = page.css_first('.quote')
+quote_text = first_quote.css('.text::text')
+quote_text = page.css('.quote').css_first('.text::text') # Chained selectors
+quote_text = page.css_first('.quote .text').text # Using `css_first` is faster than `css` if you want the first element
+author = first_quote.next_sibling.css('.author::text')
+parent_container = first_quote.parent
+
+# Element relationships and similarity
+similar_elements = first_quote.find_similar()
+below_elements = first_quote.below_elements()
+```
+You can use the parser right away if you don't want to fetch websites like below:
+```python
+from scrapling.parser import Selector
+
+page = Selector("...")
+```
+And it works exactly the same!
+
+### Async Session Management Examples
+```python
+import asyncio
+from scrapling.fetchers import FetcherSession, AsyncStealthySession, AsyncDynamicSession
+
+async with FetcherSession(http3=True) as session: # `FetcherSession` is context-aware and can work in both sync/async patterns
+ page1 = session.get('https://quotes.toscrape.com/')
+ page2 = session.get('https://quotes.toscrape.com/', impersonate='firefox135')
+
+# Async session usage
+async with AsyncStealthySession(max_pages=2) as session:
+ tasks = []
+ urls = ['https://example.com/page1', 'https://example.com/page2']
+
+ for url in urls:
+ task = session.fetch(url)
+ tasks.append(task)
+
+ print(session.get_pool_stats()) # Optional - The status of the browser tabs pool (busy/free/error)
+ results = await asyncio.gather(*tasks)
+ print(session.get_pool_stats())
+```
+
+## CLI & Interactive Shell
+
+Scrapling v0.3 includes a powerful command-line interface:
+
+```bash
+# Launch interactive Web Scraping shell
+scrapling shell
+
+# Extract pages to a file directly without programming (Extracts the content inside `body` tag by default)
+# If the output file ends with `.txt`, then the text content of the target will be extracted.
+# If ended with `.md`, it will be a markdown representation of the HTML content, and `.html` will be the HTML content right away.
+scrapling extract get 'https://example.com' content.md
+scrapling extract get 'https://example.com' content.txt --css-selector '#fromSkipToProducts' --impersonate 'chrome' # All elements matching the CSS selector '#fromSkipToProducts'
+scrapling extract fetch 'https://example.com' content.md --css-selector '#fromSkipToProducts' --no-headless
+scrapling extract stealthy-fetch 'https://nopecha.com/demo/cloudflare' captchas.html --css-selector '#padded_content a' --solve-cloudflare
```
-To keep it simple, all methods can be chained on top of each other!

-## Parsing Performance
+## Performance Benchmarks
-Scrapling isn't just powerful - it's also blazing fast. Scrapling implements many best practices, design patterns, and numerous optimizations to save fractions of seconds. All of that while focusing exclusively on parsing HTML documents.
-Here are benchmarks comparing Scrapling to popular Python libraries in two tests.
-
-### Text Extraction Speed Test (5000 nested elements).
-
-This test consists of extracting the text content of 5000 nested div elements.
+Scrapling isn't just powerful—it's also blazing fast, and version 0.3 delivers exceptional performance improvements across all operations!
+### Text Extraction Speed Test (5000 nested elements)
| # | Library | Time (ms) | vs Scrapling |
|---|:-----------------:|:---------:|:------------:|
-| 1 | Scrapling | 5.44 | 1.0x |
-| 2 | Parsel/Scrapy | 5.53 | 1.017x |
-| 3 | Raw Lxml | 6.76 | 1.243x |
-| 4 | PyQuery | 21.96 | 4.037x |
-| 5 | Selectolax | 67.12 | 12.338x |
-| 6 | BS4 with Lxml | 1307.03 | 240.263x |
-| 7 | MechanicalSoup | 1322.64 | 243.132x |
-| 8 | BS4 with html5lib | 3373.75 | 620.175x |
+| 1 | Scrapling | 1.88 | 1.0x |
+| 2 | Parsel/Scrapy | 1.96 | 1.043x |
+| 3 | Raw Lxml | 2.32 | 1.234x |
+| 4 | PyQuery | 20.2 | ~11x |
+| 5 | Selectolax | 85.2 | ~45x |
+| 6 | MechanicalSoup | 1305.84 | ~695x |
+| 7 | BS4 with Lxml | 1307.92 | ~696x |
+| 8 | BS4 with html5lib | 3336.28 | ~1775x |
-As you see, Scrapling is on par with Scrapy and slightly faster than Lxml, which both libraries are built on top of. These are the closest results to Scrapling. PyQuery is also built on top of Lxml, but Scrapling is four times faster.
+### Element Similarity & Text Search Performance
-### Extraction By Text Speed Test
-
-Scrapling can find elements based on its text content and find elements similar to these elements. The only known library with these two features, too, is AutoScraper.
-
-So, we compared this to see how fast Scrapling can be in these two tasks compared to AutoScraper.
-
-Here are the results:
+Scrapling's adaptive element finding capabilities significantly outperform alternatives:
| Library | Time (ms) | vs Scrapling |
|-------------|:---------:|:------------:|
-| Scrapling | 2.51 | 1.0x |
-| AutoScraper | 11.41 | 4.546x |
+| Scrapling | 2.02 | 1.0x |
+| AutoScraper | 10.26 | 5.08x |
-Scrapling can find elements with more methods and returns the entire element's `Selector` object, not only text like AutoScraper. So, to make this test fair, both libraries will extract an element with text, find similar elements, and then extract the text content for all of them.
-As you see, Scrapling is still 4.5 times faster at the same task.
-
-If we made Scrapling extract the elements only without stopping to extract each element's text, we would get speed twice as fast as this, but as I said, to make it fair comparison a bit :smile:

-## Known Issues
-- In the auto-matching save process, the unique properties of the first element from the selection results are the only ones that get saved. If the selector you are using selects different elements on the page in different locations, auto-matching will return the first element to you only when you relocate it later. This doesn't include combined CSS selectors (Using commas to combine more than one selector, for example), as these selectors get separated, and each selector gets executed alone.

-Scrapling is an Undetectable, high-performance, intelligent Web scraping library for Python 3 to make Web Scraping easy!
+
+ Easy, effortless Web Scraping as it should be!
+
-Scrapling isn't only about making undetectable requests or fetching pages under the radar!
+**Stop fighting anti-bot systems. Stop rewriting selectors after every website update.**
-It has its own parser that adapts to website changes and provides many element selection/querying options other than traditional selectors, powerful DOM traversal API, and many other features while significantly outperforming popular parsing alternatives.
+Scrapling isn't just another Web Scraping library. It's the first **adaptive** scraping library that learns from website changes and evolves with them. While other libraries break when websites update their structure, Scrapling automatically relocates your elements and keeps your scrapers running.
-Scrapling is built from the ground up by Web scraping experts for beginners and experts. The goal is to provide powerful features while maintaining simplicity and minimal boilerplate code.
+Built for the modern Web, Scrapling has its own rapid parsing engine and its fetchers to handle all Web Scraping challenges you are facing or will face. Built by Web Scrapers for Web Scrapers and regular users, there's something for everyone.
```python
->> from scrapling.fetchers import Fetcher, AsyncFetcher, StealthyFetcher, PlayWrightFetcher
->> StealthyFetcher.auto_match = True
+>> from scrapling.fetchers import Fetcher, AsyncFetcher, StealthyFetcher, DynamicFetcher
+>> StealthyFetcher.adaptive = True
# Fetch websites' source under the radar!
>> page = StealthyFetcher.fetch('https://example.com', headless=True, network_idle=True)
>> print(page.status)
200
>> products = page.css('.product', auto_save=True) # Scrape data that survives website design changes!
->> # Later, if the website structure changes, pass `auto_match=True`
->> products = page.css('.product', auto_match=True) # and Scrapling still finds them!
+>> # Later, if the website structure changes, pass `adaptive=True`
