Translations are available at https://www.contributor-covenant.org/translations. ================================================ FILE: CONTRIBUTING.md ================================================ # Contributing to Scrapling Thank you for your interest in contributing to Scrapling! Everybody is invited and welcome to contribute to Scrapling. Minor changes are more likely to be included promptly. Adding unit tests for new features or test cases for bugs you've fixed helps us ensure that the Pull Request (PR) is acceptable. There are many ways to contribute to Scrapling. Here are some of them: - Report bugs and request features using the [GitHub issues](https://github.com/D4Vinci/Scrapling/issues). Please follow the issue template to help us resolve your issue quickly. - Blog about Scrapling. Tell the world how you’re using Scrapling. This will help newcomers with more examples and increase the Scrapling project's visibility. - Join the [Discord community](https://discord.gg/EMgGbDceNQ) and share your ideas on how to improve Scrapling. We’re always open to suggestions. - If you are not a developer, perhaps you would like to help with translating the [documentation](https://github.com/D4Vinci/Scrapling/tree/docs)? ## Making a Pull Request To ensure that your PR gets accepted, please make sure that your PR is based on the latest changes from the dev branch and that it satisfies the following requirements: - **The PR must be made against the [**dev**](https://github.com/D4Vinci/Scrapling/tree/dev) branch of Scrapling. Any PR made against the main branch will be rejected.** - **The code should be passing all available tests. We use tox with GitHub's CI to run the current tests on all supported Python versions for every code-related commit.** - **The code should be passing all code quality checks like `mypy` and `pyright`. We are using GitHub's CI to enforce code style checks as well.** - **Make your changes, keep the code clean with an explanation of any part that might be vague, and remember to create a separate virtual environment for this project.** - If you are adding a new feature, please add tests for it. - If you are fixing a bug, please add code with the PR that reproduces the bug. - Please follow the rules and coding style rules we explain below. ## Finding work If you have decided to make a contribution to Scrapling, but you do not know what to contribute, here are some ways to find pending work: - Check out the [contribution](https://github.com/D4Vinci/Scrapling/contribute) GitHub page, which lists open issues tagged as `good first issue`. These issues provide a good starting point. - There are also the [help wanted](https://github.com/D4Vinci/Scrapling/issues?q=is%3Aissue%20label%3A%22help%20wanted%22%20state%3Aopen) issues, but know that some may require familiarity with the Scrapling code base first. You can also target any other issue, provided it is not tagged as `invalid`, `wontfix`, or similar tags. - If you enjoy writing automated tests, you can work on increasing our test coverage. Currently, the test coverage is around 90–92%. - Join the [Discord community](https://discord.gg/EMgGbDceNQ) and ask questions in the `#help` channel. ## Coding style Please follow these coding conventions as we do when writing code for Scrapling: - We use [pre-commit](https://pre-commit.com/) to automatically address simple code issues before every commit, so please install it and run `pre-commit install` to set it up. This will install hooks to run [ruff](https://docs.astral.sh/ruff/), [bandit](https://github.com/PyCQA/bandit), and [vermin](https://github.com/netromdk/vermin) on every commit. We are currently using a workflow to automatically run these tools on every PR, so if your code doesn't pass these checks, the PR will be rejected. - We use type hints for better code clarity and [pyright](https://github.com/microsoft/pyright)/[mypy](https://github.com/python/mypy) for static type checking. If your code isn't acceptable by those tools, your PR won't pass the code quality rule. - We use the conventional commit messages format as [here](https://gist.github.com/qoomon/5dfcdf8eec66a051ecd85625518cfd13#types), so for example, we use the following prefixes for commit messages: | Prefix | When to use it | |-------------|--------------------------| | `feat:` | New feature added | | `fix:` | Bug fix | | `docs:` | Documentation change/add | | `test:` | Tests | | `refactor:` | Code refactoring | | `chore:` | Maintenance tasks | Then include the details of the change in the commit message body/description. Example: ``` feat: add `adaptive` for similar elements - Added find_similar() method - Implemented pattern matching - Added tests and documentation ``` > Please don’t put your name in the code you contribute; git provides enough metadata to identify the author of the code. ## Development ### Getting started 1. Fork the repository and clone your fork: ```bash git clone https://github.com//Scrapling.git cd Scrapling git checkout dev ``` 2. Create a virtual environment and install dependencies: ```bash python -m venv .venv source .venv/bin/activate # On Windows: .venv\Scripts\activate pip install -e ".[all]" pip install -r tests/requirements.txt ``` 3. Install browser dependencies: ```bash scrapling install ``` 4. Set up pre-commit hooks: ```bash pip install pre-commit pre-commit install ``` ### Tips Setting the scrapling logging level to `debug` makes it easier to know what's happening in the background. ```python import logging logging.getLogger("scrapling").setLevel(logging.DEBUG) ``` Bonus: You can install the beta of the upcoming update from the dev branch as follows ```commandline pip3 install git+https://github.com/D4Vinci/Scrapling.git@dev ``` ## Tests Scrapling includes a comprehensive test suite that can be executed with pytest. However, first, you need to install all libraries and `pytest-plugins` listed in `tests/requirements.txt`. Then, running the tests will result in an output like this: ```bash $ pytest tests -n auto =============================== test session starts =============================== platform darwin -- Python 3.13.8, pytest-8.4.2, pluggy-1.6.0 -- /Users//.venv/bin/python3.13 cachedir: .pytest_cache rootdir: /Users//scrapling configfile: pytest.ini plugins: asyncio-1.2.0, anyio-4.11.0, xdist-3.8.0, httpbin-2.1.0, cov-7.0.0 asyncio: mode=Mode.STRICT, asyncio_default_fixture_loop_scope=function, asyncio_default_test_loop_scope=function 10 workers [515 items] scheduling tests via LoadScheduling ...... =============================== 271 passed in 52.68s ============================== ``` Here, `-n auto` runs tests in parallel across multiple processes to increase speed. **Note:** You may need to run browser tests sequentially (`DynamicFetcher`/`StealthyFetcher`) to avoid conflicts. To run non-browser tests in parallel and browser tests separately: ```bash # Non-browser tests (parallel) pytest tests/ -k "not (DynamicFetcher or StealthyFetcher)" -n auto # Browser tests (sequential) pytest tests/ -k "DynamicFetcher or StealthyFetcher" ``` Bonus: You can also see the test coverage with the `pytest` plugin below ```bash pytest --cov=scrapling tests/ ``` ## Building Documentation Documentation is built using [Zensical](https://zensical.org/).

Scrapling is an adaptive Web Scraping framework that handles everything from a single request to a full-scale crawl. Its parser learns from website changes and automatically relocates your elements when pages update. Its fetchers bypass anti-bot systems like Cloudflare Turnstile out of the box. And its spider framework lets you scale up to concurrent, multi-session crawls with pause/resume and automatic proxy rotation — all in a few lines of Python. One library, zero compromises. Blazing fast crawls with real-time stats and streaming. Built by Web Scrapers for Web Scrapers and regular users, there's something for everyone. ```python from scrapling.fetchers import Fetcher, AsyncFetcher, StealthyFetcher, DynamicFetcher StealthyFetcher.adaptive = True p = StealthyFetcher.fetch('https://example.com', headless=True, network_idle=True) # Fetch website under the radar! products = p.css('.product', auto_save=True) # Scrape data that survives website design changes! products = p.css('.product', adaptive=True) # Later, if the website structure changes, pass `adaptive=True` to find them! ``` Or scale up to full crawls ```python from scrapling.spiders import Spider, Response class MySpider(Spider): name = "demo" start_urls = ["https://example.com/"] async def parse(self, response: Response): for item in response.css('.product'): yield {"title": item.css('h2::text').get()} MySpider().start() ```

Click [here](https://github.com/sponsors/D4Vinci) and choose the tier that suites you! --- ## Key Features ### Spiders — A Full Crawling Framework - 🕷️ **Scrapy-like Spider API**: Define spiders with `start_urls`, async `parse` callbacks, and `Request`/`Response` objects. - ⚡ **Concurrent Crawling**: Configurable concurrency limits, per-domain throttling, and download delays. - 🔄 **Multi-Session Support**: Unified interface for HTTP requests, and stealthy headless browsers in a single spider — route requests to different sessions by ID. - 💾 **Pause & Resume**: Checkpoint-based crawl persistence. Press Ctrl+C for a graceful shutdown; restart to resume from where you left off. - 📡 **Streaming Mode**: Stream scraped items as they arrive via `async for item in spider.stream()` with real-time stats — ideal for UI, pipelines, and long-running crawls. - 🛡️ **Blocked Request Detection**: Automatic detection and retry of blocked requests with customizable logic. - 📦 **Built-in Export**: Export results through hooks and your own pipeline or the built-in JSON/JSONL with `result.items.to_json()` / `result.items.to_jsonl()` respectively. ### Advanced Websites Fetching with Session Support - **HTTP Requests**: Fast and stealthy HTTP requests with the `Fetcher` class. Can impersonate browsers' TLS fingerprint, headers, and use HTTP/3. - **Dynamic Loading**: Fetch dynamic websites with full browser automation through the `DynamicFetcher` class supporting Playwright's Chromium and Google's Chrome. - **Anti-bot Bypass**: Advanced stealth capabilities with `StealthyFetcher` and fingerprint spoofing. Can easily bypass all types of Cloudflare's Turnstile/Interstitial with automation. - **Session Management**: Persistent session support with `FetcherSession`, `StealthySession`, and `DynamicSession` classes for cookie and state management across requests. - **Proxy Rotation**: Built-in `ProxyRotator` with cyclic or custom rotation strategies across all session types, plus per-request proxy overrides. - **Domain Blocking**: Block requests to specific domains (and their subdomains) in browser-based fetchers. - **Async Support**: Complete async support across all fetchers and dedicated async session classes. ### Adaptive Scraping & AI Integration - 🔄 **Smart Element Tracking**: Relocate elements after website changes using intelligent similarity algorithms. - 🎯 **Smart Flexible Selection**: CSS selectors, XPath selectors, filter-based search, text search, regex search, and more. - 🔍 **Find Similar Elements**: Automatically locate elements similar to found elements. - 🤖 **MCP Server to be used with AI**: Built-in MCP server for AI-assisted Web Scraping and data extraction. The MCP server features powerful, custom capabilities that leverage Scrapling to extract targeted content before passing it to the AI (Claude/Cursor/etc), thereby speeding up operations and reducing costs by minimizing token usage. ([demo video](https://www.youtube.com/watch?v=qyFk3ZNwOxE)) ### High-Performance & battle-tested Architecture - 🚀 **Lightning Fast**: Optimized performance outperforming most Python scraping libraries. - 🔋 **Memory Efficient**: Optimized data structures and lazy loading for a minimal memory footprint. - ⚡ **Fast JSON Serialization**: 10x faster than the standard library. - 🏗️ **Battle tested**: Not only does Scrapling have 92% test coverage and full type hints coverage, but it has been used daily by hundreds of Web Scrapers over the past year. ### Developer/Web Scraper Friendly Experience - 🎯 **Interactive Web Scraping Shell**: Optional built-in IPython shell with Scrapling integration, shortcuts, and new tools to speed up Web Scraping scripts development, like converting curl requests to Scrapling requests and viewing requests results in your browser. - 🚀 **Use it directly from the Terminal**: Optionally, you can use Scrapling to scrape a URL without writing a single line of code! - 🛠️ **Rich Navigation API**: Advanced DOM traversal with parent, sibling, and child navigation methods. - 🧬 **Enhanced Text Processing**: Built-in regex, cleaning methods, and optimized string operations. - 📝 **Auto Selector Generation**: Generate robust CSS/XPath selectors for any element. - 🔌 **Familiar API**: Similar to Scrapy/BeautifulSoup with the same pseudo-elements used in Scrapy/Parsel. - 📘 **Complete Type Coverage**: Full type hints for excellent IDE support and code completion. The entire codebase is automatically scanned with **PyRight** and **MyPy** with each change. - 🔋 **Ready Docker image**: With each release, a Docker image containing all browsers is automatically built and pushed. ## Getting Started Let's give you a quick glimpse of what Scrapling can do without deep diving. ### Basic Usage HTTP requests with session support ```python from scrapling.fetchers import Fetcher, FetcherSession 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').getall() # Or use one-off requests page = Fetcher.get('https://quotes.toscrape.com/') quotes = page.css('.quote .text::text').getall() ``` Advanced stealth mode ```python from scrapling.fetchers import StealthyFetcher, StealthySession with StealthySession(headless=True, solve_cloudflare=True) as session: # Keep the browser open until you finish page = session.fetch('https://nopecha.com/demo/cloudflare', google_search=False) data = page.css('#padded_content a').getall() # 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').getall() ``` Full browser automation ```python from scrapling.fetchers import DynamicFetcher, DynamicSession with DynamicSession(headless=True, disable_resources=False, network_idle=True) as session: # Keep the browser open until you finish page = session.fetch('https://quotes.toscrape.com/', load_dom=False) data = page.xpath('//span[@class="text"]/text()').getall() # 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').getall() ``` ### Spiders Build full crawlers with concurrent requests, multiple session types, and pause/resume: ```python from scrapling.spiders import Spider, Request, Response class QuotesSpider(Spider): name = "quotes" start_urls = ["https://quotes.toscrape.com/"] concurrent_requests = 10 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(), } next_page = response.css('.next a') if next_page: yield response.follow(next_page[0].attrib['href']) result = QuotesSpider().start() print(f"Scraped {len(result.items)} quotes") result.items.to_json("quotes.json") ``` Use multiple session types in a single spider: ```python from scrapling.spiders import Spider, Request, Response from scrapling.fetchers import FetcherSession, AsyncStealthySession class MultiSessionSpider(Spider): name = "multi" 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(): # Route protected pages through the stealth session if "protected" in link: yield Request(link, sid="stealth") else: yield Request(link, sid="fast", callback=self.parse) # explicit callback ``` Pause and resume long crawls with checkpoints by running the spider like this: ```python QuotesSpider(crawldir="./crawl_data").start() ``` Press Ctrl+C to pause gracefully — progress is saved automatically. Later, when you start the spider again, pass the same `crawldir`, and it will resume from where it stopped. ### Advanced Parsing & Navigation ```python from scrapling.fetchers import Fetcher # Rich element selection and navigation page = Fetcher.get('https://quotes.toscrape.com/') # 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') # Advanced navigation quote_text = page.css('.quote')[0].css('.text::text').get() quote_text = page.css('.quote').css('.text::text').getall() # Chained selectors first_quote = page.css('.quote')[0] 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 precisely the same way! ### 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 includes a powerful command-line interface: [![asciicast](https://asciinema.org/a/736339.svg)](https://asciinema.org/a/736339) Launch the interactive Web Scraping shell ```bash scrapling shell ``` Extract pages to a file directly without programming (Extracts the content inside the `body` tag by default). If the output file ends with `.txt`, then the text content of the target will be extracted. If it ends in `.md`, it will be a Markdown representation of the HTML content; if it ends in `.html`, it will be the HTML content itself. ```bash 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 ``` > [!NOTE] > There are many additional features, but we want to keep this page concise, including the MCP server and the interactive Web Scraping Shell. Check out the full documentation [here](https://scrapling.readthedocs.io/en/latest/) ## Performance Benchmarks Scrapling isn't just powerful—it's also blazing fast. The following benchmarks compare Scrapling's parser with the latest versions of other popular libraries. ### Text Extraction Speed Test (5000 nested elements) | # | Library | Time (ms) | vs Scrapling | |---|:-----------------:|:---------:|:------------:| | 1 | Scrapling | 2.02 | 1.0x | | 2 | Parsel/Scrapy | 2.04 | 1.01 | | 3 | Raw Lxml | 2.54 | 1.257 | | 4 | PyQuery | 24.17 | ~12x | | 5 | Selectolax | 82.63 | ~41x | | 6 | MechanicalSoup | 1549.71 | ~767.1x | | 7 | BS4 with Lxml | 1584.31 | ~784.3x | | 8 | BS4 with html5lib | 3391.91 | ~1679.1x | ### Element Similarity & Text Search Performance Scrapling's adaptive element finding capabilities significantly outperform alternatives: | Library | Time (ms) | vs Scrapling | |-------------|:---------:|:------------:| | Scrapling | 2.39 | 1.0x | | AutoScraper | 12.45 | 5.209x | > All benchmarks represent averages of 100+ runs. See [benchmarks.py](https://github.com/D4Vinci/Scrapling/blob/main/benchmarks.py) for methodology. ## Installation Scrapling requires Python 3.10 or higher: ```bash pip install scrapling ``` This installation only includes the parser engine and its dependencies, without any fetchers or commandline dependencies. ### Optional Dependencies 1. If you are going to use any of the extra features below, the fetchers, or their classes, you will need to install fetchers' dependencies and their browser dependencies as follows: ```bash pip install "scrapling[fetchers]" scrapling install # normal install scrapling install --force # force reinstall ``` This downloads all browsers, along with their system dependencies and fingerprint manipulation dependencies. Or you can install them from the code instead of running a command like this: ```python from scrapling.cli import install install([], standalone_mode=False) # normal install install(["--force"], standalone_mode=False) # force reinstall ``` 2. Extra features: - Install the MCP server feature: ```bash pip install "scrapling[ai]" ``` - Install shell features (Web Scraping shell and the `extract` command): ```bash pip install "scrapling[shell]" ``` - Install everything: ```bash pip install "scrapling[all]" ``` Remember that you need to install the browser dependencies with `scrapling install` after any of these extras (if you didn't already) ### Docker You can also install a Docker image with all extras and browsers with the following command from DockerHub: ```bash docker pull pyd4vinci/scrapling ``` Or download it from the GitHub registry: ```bash docker pull ghcr.io/d4vinci/scrapling:latest ``` This image is automatically built and pushed using GitHub Actions and the repository's main branch. ## Contributing We welcome contributions!

Use when asked to scrape, crawl, or extract data from websites; web_fetch fails; the site has anti-bot protections; write Python code to scrape/crawl; or write spiders. version: 0.4.2 license: Complete terms in LICENSE.txt --- # Scrapling Scrapling is an adaptive Web Scraping framework that handles everything from a single request to a full-scale crawl. Its parser learns from website changes and automatically relocates your elements when pages update. Its fetchers bypass anti-bot systems like Cloudflare Turnstile out of the box. And its spider framework lets you scale up to concurrent, multi-session crawls with pause/resume and automatic proxy rotation — all in a few lines of Python. One library, zero compromises. Blazing fast crawls with real-time stats and streaming. Built by Web Scrapers for Web Scrapers and regular users, there's something for everyone. **Requires: Python 3.10+** **This is the official skill for the scrapling library by the library author.** ## Setup (once) Create a virtual Python environment through any way available, like `venv`, then inside the environment do: `pip install "scrapling[all]>=0.4.2"` Then do this to download all the browsers' dependencies: ```bash scrapling install --force ``` Make note of the `scrapling` binary path and use it instead of `scrapling` from now on with all commands (if `scrapling` is not on `$PATH`). ### Docker Another option if the user doesn't have Python or doesn't want to use it is to use the Docker image, but this can be used only in the commands, so no writing Python code for scrapling this way: ```bash docker pull pyd4vinci/scrapling ``` or ```bash docker pull ghcr.io/d4vinci/scrapling:latest ``` ## CLI Usage The `scrapling extract` command group lets you download and extract content from websites directly without writing any code. ```bash Usage: scrapling extract [OPTIONS] COMMAND [ARGS]... Commands: get Perform a GET request and save the content to a file. post Perform a POST request and save the content to a file. put Perform a PUT request and save the content to a file. delete Perform a DELETE request and save the content to a file. fetch Use a browser to fetch content with browser automation and flexible options. stealthy-fetch Use a stealthy browser to fetch content with advanced stealth features. ``` ### Usage pattern - Choose your output format by changing the file extension. Here are some examples for the `scrapling extract get` command: - Convert the HTML content to Markdown, then save it to the file (great for documentation): `scrapling extract get "https://blog.example.com" article.md` - Save the HTML content as it is to the file: `scrapling extract get "https://example.com" page.html` - Save a clean version of the text content of the webpage to the file: `scrapling extract get "https://example.com" content.txt` - Output to a temp file, read it back, then clean up. - All commands can use CSS selectors to extract specific parts of the page through `--css-selector` or `-s`. Which command to use generally: - Use **`get`** with simple websites, blogs, or news articles. - Use **`fetch`** with modern web apps, or sites with dynamic content. - Use **`stealthy-fetch`** with protected sites, Cloudflare, or anti-bot systems. > When unsure, start with `get`. If it fails or returns empty content, escalate to `fetch`, then `stealthy-fetch`. The speed of `fetch` and `stealthy-fetch` is nearly the same, so you are not sacrificing anything. #### Key options (requests) Those options are shared between the 4 HTTP request commands: | Option | Input type | Description | |:-------------------------------------------|:----------:|:-----------------------------------------------------------------------------------------------------------------------------------------------| | -H, --headers | TEXT | HTTP headers in format "Key: Value" (can be used multiple times) | | --cookies | TEXT | Cookies string in format "name1=value1; name2=value2" | | --timeout | INTEGER | Request timeout in seconds (default: 30) | | --proxy | TEXT | Proxy URL in format "http://username:password@host:port" | | -s, --css-selector | TEXT | CSS selector to extract specific content from the page.

Here's a quick overview of how to code with scrapling. ### Basic Usage HTTP requests with session support ```python from scrapling.fetchers import Fetcher, FetcherSession 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').getall() # Or use one-off requests page = Fetcher.get('https://quotes.toscrape.com/') quotes = page.css('.quote .text::text').getall() ``` Advanced stealth mode ```python from scrapling.fetchers import StealthyFetcher, StealthySession with StealthySession(headless=True, solve_cloudflare=True) as session: # Keep the browser open until you finish page = session.fetch('https://nopecha.com/demo/cloudflare', google_search=False) data = page.css('#padded_content a').getall() # 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').getall() ``` Full browser automation ```python from scrapling.fetchers import DynamicFetcher, DynamicSession with DynamicSession(headless=True, disable_resources=False, network_idle=True) as session: # Keep the browser open until you finish page = session.fetch('https://quotes.toscrape.com/', load_dom=False) data = page.xpath('//span[@class="text"]/text()').getall() # 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').getall() ``` ### Spiders Build full crawlers with concurrent requests, multiple session types, and pause/resume: ```python from scrapling.spiders import Spider, Request, Response class QuotesSpider(Spider): name = "quotes" start_urls = ["https://quotes.toscrape.com/"] concurrent_requests = 10 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(), } next_page = response.css('.next a') if next_page: yield response.follow(next_page[0].attrib['href']) result = QuotesSpider().start() print(f"Scraped {len(result.items)} quotes") result.items.to_json("quotes.json") ``` Use multiple session types in a single spider: ```python from scrapling.spiders import Spider, Request, Response from scrapling.fetchers import FetcherSession, AsyncStealthySession class MultiSessionSpider(Spider): name = "multi" 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(): # Route protected pages through the stealth session if "protected" in link: yield Request(link, sid="stealth") else: yield Request(link, sid="fast", callback=self.parse) # explicit callback ``` Pause and resume long crawls with checkpoints by running the spider like this: ```python QuotesSpider(crawldir="./crawl_data").start() ``` Press Ctrl+C to pause gracefully — progress is saved automatically. Later, when you start the spider again, pass the same `crawldir`, and it will resume from where it stopped. ### Advanced Parsing & Navigation ```python from scrapling.fetchers import Fetcher # Rich element selection and navigation page = Fetcher.get('https://quotes.toscrape.com/') # 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') # Advanced navigation quote_text = page.css('.quote')[0].css('.text::text').get() quote_text = page.css('.quote').css('.text::text').getall() # Chained selectors first_quote = page.css('.quote')[0] 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 precisely the same way! ### 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()) ``` ## References You already had a good glimpse of what the library can do.

All fetchers have separate session classes to keep the session running (e.g., a browser fetcher keeps the browser open until you finish all requests). Fetchers are not wrappers built on top of other libraries. They use these libraries as an engine to request/fetch pages but add features the underlying engines don't have, while still fully leveraging and optimizing them for web scraping. ## Fetchers Overview Scrapling provides three different fetcher classes with their session classes; each fetcher is designed for a specific use case. The following table compares them and can be quickly used for guidance. | Feature | Fetcher | DynamicFetcher | StealthyFetcher | |--------------------|---------------------------------------------------|-----------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------| | Relative speed | 🐇🐇🐇🐇🐇 | 🐇🐇🐇 | 🐇🐇🐇 | | Stealth | ⭐⭐ | ⭐⭐⭐ | ⭐⭐⭐⭐⭐ | | Anti-Bot options | ⭐⭐ | ⭐⭐⭐ | ⭐⭐⭐⭐⭐ | | JavaScript loading | ❌ | ✅ | ✅ | | Memory Usage | ⭐ | ⭐⭐⭐ | ⭐⭐⭐ | | Best used for | Basic scraping when HTTP requests alone can do it | - Dynamically loaded websites
- Small automation
- Small-Mid protections | - Dynamically loaded websites
- Small automation
- Small-Complicated protections | | Browser(s) | ❌ | Chromium and Google Chrome | Chromium and Google Chrome | | Browser API used | ❌ | PlayWright | PlayWright | | Setup Complexity | Simple | Simple | Simple | ## Parser configuration in all fetchers All fetchers share the same import method, as you will see in the upcoming pages ```python >>> from scrapling.fetchers import Fetcher, AsyncFetcher, StealthyFetcher, DynamicFetcher ``` Then you use it right away without initializing like this, and it will use the default parser settings: ```python >>> page = StealthyFetcher.fetch('https://example.com') ``` If you want to configure the parser ([Selector class](parsing/main_classes.md#selector)) that will be used on the response before returning it for you, then do this first: ```python >>> from scrapling.fetchers import Fetcher >>> Fetcher.configure(adaptive=True, keep_comments=False, keep_cdata=False) # and the rest ``` or ```python >>> from scrapling.fetchers import Fetcher >>> Fetcher.adaptive=True >>> Fetcher.keep_comments=False >>> Fetcher.keep_cdata=False # and the rest ``` Then, continue your code as usual. The available configuration arguments are: `adaptive`, `adaptive_domain`, `huge_tree`, `keep_comments`, `keep_cdata`, `storage`, and `storage_args`, which are the same ones you give to the [Selector](parsing/main_classes.md#selector) class. You can display the current configuration anytime by running `.display_config()`. **Info:** The `adaptive` argument is disabled by default; you must enable it to use that feature. ### Set parser config per request As you probably understand, the logic above for setting the parser config will apply globally to all requests/fetches made through that class, and it's intended for simplicity. If your use case requires a different configuration for each request/fetch, you can pass a dictionary to the request method (`fetch`/`get`/`post`/...) to an argument named `selector_config`. ## Response Object The `Response` object is the same as the [Selector](parsing/main_classes.md#selector) class, but it has additional details about the response, like response headers, status, cookies, etc., as shown below: ```python >>> from scrapling.fetchers import Fetcher >>> page = Fetcher.get('https://example.com') >>> page.status # HTTP status code >>> page.reason # Status message >>> page.cookies # Response cookies as a dictionary >>> page.headers # Response headers >>> page.request_headers # Request headers >>> page.history # Response history of redirections, if any >>> page.body # Raw response body as bytes >>> page.encoding # Response encoding >>> page.meta # Response metadata dictionary (e.g., proxy used). Mainly helpful with the spiders system. ``` All fetchers return the `Response` object. **Note:** Unlike the [Selector](parsing/main_classes.md#selector) class, the `Response` class's body is always bytes since v0.4. ================================================ FILE: agent-skill/Scrapling-Skill/references/fetching/dynamic.md ================================================ # Fetching dynamic websites `DynamicFetcher` (formerly `PlayWrightFetcher`) provides flexible browser automation with multiple configuration options and built-in stealth improvements. As we will explain later, to automate the page, you need some knowledge of [Playwright's Page API](https://playwright.dev/python/docs/api/class-page). ## Basic Usage You have one primary way to import this Fetcher, which is the same for all fetchers. ```python >>> from scrapling.fetchers import DynamicFetcher ``` Check out how to configure the parsing options [here](choosing.md#parser-configuration-in-all-fetchers) **Note:** The async version of the `fetch` method is `async_fetch`. This fetcher provides three main run options that can be combined as desired. Which are: ### 1. Vanilla Playwright ```python DynamicFetcher.fetch('https://example.com') ``` Using it in that manner will open a Chromium browser and load the page. There are optimizations for speed, and some stealth goes automatically under the hood, but other than that, there are no tricks or extra features unless you enable some; it's just a plain PlayWright API. ### 2. Real Chrome ```python DynamicFetcher.fetch('https://example.com', real_chrome=True) ``` If you have a Google Chrome browser installed, use this option. It's the same as the first option, but it will use the Google Chrome browser you installed on your device instead of Chromium. This will make your requests look more authentic, so they're less detectable for better results. If you don't have Google Chrome installed and want to use this option, you can use the command below in the terminal to install it for the library instead of installing it manually: ```commandline playwright install chrome ``` ### 3. CDP Connection ```python DynamicFetcher.fetch('https://example.com', cdp_url='ws://localhost:9222') ``` Instead of launching a browser locally (Chromium/Google Chrome), you can connect to a remote browser through the [Chrome DevTools Protocol](https://chromedevtools.github.io/devtools-protocol/). **Notes:** * There was a `stealth` option here, but it was moved to the `StealthyFetcher` class, as explained on the next page, with additional features since version 0.3.13. * This makes it less confusing for new users, easier to maintain, and provides other benefits, as explained on the [StealthyFetcher page](stealthy.md). ## Full list of arguments All arguments for `DynamicFetcher` and its session classes: | Argument | Description | Optional | |:-------------------:|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|:--------:| | url | Target url | ❌ | | headless | Pass `True` to run the browser in headless/hidden (**default**) or `False` for headful/visible mode. | ✔️ | | disable_resources | Drop requests for unnecessary resources for a speed boost. Requests dropped are of type `font`, `image`, `media`, `beacon`, `object`, `imageset`, `texttrack`, `websocket`, `csp_report`, and `stylesheet`. | ✔️ | | cookies | Set cookies for the next request. | ✔️ | | useragent | Pass a useragent string to be used. **Otherwise, the fetcher will generate and use a real Useragent of the same browser and version.** | ✔️ | | network_idle | Wait for the page until there are no network connections for at least 500 ms. | ✔️ | | load_dom | Enabled by default, wait for all JavaScript on page(s) to fully load and execute (wait for the `domcontentloaded` state). | ✔️ | | timeout | The timeout (milliseconds) used in all operations and waits through the page. The default is 30,000 ms (30 seconds). | ✔️ | | wait | The time (milliseconds) the fetcher will wait after everything finishes before closing the page and returning the `Response` object. | ✔️ | | page_action | Added for automation. Pass a function that takes the `page` object and does the necessary automation. | ✔️ | | wait_selector | Wait for a specific css selector to be in a specific state. | ✔️ | | init_script | An absolute path to a JavaScript file to be executed on page creation for all pages in this session. | ✔️ | | wait_selector_state | Scrapling will wait for the given state to be fulfilled for the selector given with `wait_selector`. _Default state is `attached`._ | ✔️ | | google_search | Enabled by default, Scrapling will set a Google referer header. | ✔️ | | extra_headers | A dictionary of extra headers to add to the request. _The referer set by `google_search` takes priority over the referer set here if used together._ | ✔️ | | proxy | The proxy to be used with requests. It can be a string or a dictionary with only the keys 'server', 'username', and 'password'. | ✔️ | | real_chrome | If you have a Chrome browser installed on your device, enable this, and the Fetcher will launch and use an instance of your browser. | ✔️ | | locale | Specify user locale, for example, `en-GB`, `de-DE`, etc. Locale will affect `navigator.language` value, `Accept-Language` request header value, as well as number and date formatting rules. Defaults to the system default locale. | ✔️ | | timezone_id | Changes the timezone of the browser. Defaults to the system timezone. | ✔️ | | cdp_url | Instead of launching a new browser instance, connect to this CDP URL to control real browsers through CDP. | ✔️ | | user_data_dir | Path to a User Data Directory, which stores browser session data like cookies and local storage. The default is to create a temporary directory. **Only Works with sessions** | ✔️ | | extra_flags | A list of additional browser flags to pass to the browser on launch. | ✔️ | | additional_args | Additional arguments to be passed to Playwright's context as additional settings, and they take higher priority than Scrapling's settings. | ✔️ | | selector_config | A dictionary of custom parsing arguments to be used when creating the final `Selector`/`Response` class. | ✔️ | | blocked_domains | A set of domain names to block requests to. Subdomains are also matched (e.g., `"example.com"` blocks `"sub.example.com"` too). | ✔️ | | proxy_rotator | A `ProxyRotator` instance for automatic proxy rotation. Cannot be combined with `proxy`. | ✔️ | | retries | Number of retry attempts for failed requests. Defaults to 3. | ✔️ | | retry_delay | Seconds to wait between retry attempts. Defaults to 1. | ✔️ | In session classes, all these arguments can be set globally for the session. Still, you can configure each request individually by passing some of the arguments here that can be configured on the browser tab level like: `google_search`, `timeout`, `wait`, `page_action`, `extra_headers`, `disable_resources`, `wait_selector`, `wait_selector_state`, `network_idle`, `load_dom`, `blocked_domains`, `proxy`, and `selector_config`. **Notes:** 1. The `disable_resources` option made requests ~25% faster in tests for some websites and can help save proxy usage, but be careful with it, as it can cause some websites to never finish loading. 2. The `google_search` argument is enabled by default for all requests, setting the referer to `https://www.google.com/`. If used together with `extra_headers`, it takes priority over the referer set there. 3. Since version 0.3.13, the `stealth` option has been removed here in favor of the `StealthyFetcher` class, and the `hide_canvas` option has been moved to it. The `disable_webgl` argument has been moved to the `StealthyFetcher` class and renamed as `allow_webgl`. 4. If you didn't set a user agent and enabled headless mode, the fetcher will generate a real user agent for the same browser version and use it. If you didn't set a user agent and didn't enable headless mode, the fetcher will use the browser's default user agent, which is the same as in standard browsers in the latest versions. ## Examples ### Resource Control ```python # Disable unnecessary resources page = DynamicFetcher.fetch('https://example.com', disable_resources=True) # Blocks fonts, images, media, etc. ``` ### Domain Blocking ```python # Block requests to specific domains (and their subdomains) page = DynamicFetcher.fetch('https://example.com', blocked_domains={"ads.example.com", "tracker.net"}) ``` ### Network Control ```python # Wait for network idle (Consider fetch to be finished when there are no network connections for at least 500 ms) page = DynamicFetcher.fetch('https://example.com', network_idle=True) # Custom timeout (in milliseconds) page = DynamicFetcher.fetch('https://example.com', timeout=30000) # 30 seconds # Proxy support (It can also be a dictionary with only the keys 'server', 'username', and 'password'.) page = DynamicFetcher.fetch('https://example.com', proxy='http://username:password@host:port') ``` ### Proxy Rotation ```python from scrapling.fetchers import DynamicSession, ProxyRotator # Set up proxy rotation rotator = ProxyRotator([ "http://proxy1:8080", "http://proxy2:8080", "http://proxy3:8080", ]) # Use with session - rotates proxy automatically with each request with DynamicSession(proxy_rotator=rotator, headless=True) as session: page1 = session.fetch('https://example1.com') page2 = session.fetch('https://example2.com') # Override rotator for a specific request page3 = session.fetch('https://example3.com', proxy='http://specific-proxy:8080') ``` **Warning:** By default, all browser-based fetchers and sessions use a persistent browser context with a pool of tabs. However, since browsers can't set a proxy per tab, when you use a `ProxyRotator`, the fetcher will automatically open a separate context for each proxy, with one tab per context. Once the tab's job is done, both the tab and its context are closed. ### Downloading Files ```python page = DynamicFetcher.fetch('https://raw.githubusercontent.com/D4Vinci/Scrapling/main/images/main_cover.png') with open(file='main_cover.png', mode='wb') as f: f.write(page.body) ``` The `body` attribute of the `Response` object always returns `bytes`. ### Browser Automation This is where your knowledge about [Playwright's Page API](https://playwright.dev/python/docs/api/class-page) comes into play. The function you pass here takes the page object from Playwright's API, performs the desired action, and then the fetcher continues. This function is executed immediately after waiting for `network_idle` (if enabled) and before waiting for the `wait_selector` argument, allowing it to be used for purposes beyond automation. You can alter the page as you want. In the example below, I used the pages' [mouse events](https://playwright.dev/python/docs/api/class-mouse) to scroll the page with the mouse wheel, then move the mouse. ```python from playwright.sync_api import Page def scroll_page(page: Page): page.mouse.wheel(10, 0) page.mouse.move(100, 400) page.mouse.up() page = DynamicFetcher.fetch('https://example.com', page_action=scroll_page) ``` Of course, if you use the async fetch version, the function must also be async. ```python from playwright.async_api import Page async def scroll_page(page: Page): await page.mouse.wheel(10, 0) await page.mouse.move(100, 400) await page.mouse.up() page = await DynamicFetcher.async_fetch('https://example.com', page_action=scroll_page) ``` ### Wait Conditions ```python # Wait for the selector page = DynamicFetcher.fetch( 'https://example.com', wait_selector='h1', wait_selector_state='visible' ) ``` This is the last wait the fetcher will do before returning the response (if enabled). You pass a CSS selector to the `wait_selector` argument, and the fetcher will wait for the state you passed in the `wait_selector_state` argument to be fulfilled. If you didn't pass a state, the default would be `attached`, which means it will wait for the element to be present in the DOM. After that, if `load_dom` is enabled (the default), the fetcher will check again to see if all JavaScript files are loaded and executed (in the `domcontentloaded` state) or continue waiting. If you have enabled `network_idle`, the fetcher will wait for `network_idle` to be fulfilled again, as explained above. The states the fetcher can wait for can be any of the following ([source](https://playwright.dev/python/docs/api/class-page#page-wait-for-selector)): - `attached`: Wait for an element to be present in the DOM. - `detached`: Wait for an element to not be present in the DOM. - `visible`: wait for an element to have a non-empty bounding box and no `visibility:hidden`. Note that an element without any content or with `display:none` has an empty bounding box and is not considered visible. - `hidden`: wait for an element to be either detached from the DOM, or have an empty bounding box, or `visibility:hidden`. This is opposite to the `'visible'` option. ### Some Stealth Features ```python page = DynamicFetcher.fetch( 'https://example.com', google_search=True, useragent='Mozilla/5.0...', # Custom user agent locale='en-US', # Set browser locale ) ``` ### General example ```python from scrapling.fetchers import DynamicFetcher def scrape_dynamic_content(): # Use Playwright for JavaScript content page = DynamicFetcher.fetch( 'https://example.com/dynamic', network_idle=True, wait_selector='.content' ) # Extract dynamic content content = page.css('.content') return { 'title': content.css('h1::text').get(), 'items': [ item.text for item in content.css('.item') ] } ``` ## Session Management To keep the browser open until you make multiple requests with the same configuration, use `DynamicSession`/`AsyncDynamicSession` classes. Those classes can accept all the arguments that the `fetch` function can take, which enables you to specify a config for the entire session. ```python from scrapling.fetchers import DynamicSession # Create a session with default configuration with DynamicSession( headless=True, disable_resources=True, real_chrome=True ) as session: # Make multiple requests with the same browser instance page1 = session.fetch('https://example1.com') page2 = session.fetch('https://example2.com') page3 = session.fetch('https://dynamic-site.com') # All requests reuse the same tab on the same browser instance ``` ### Async Session Usage ```python import asyncio from scrapling.fetchers import AsyncDynamicSession async def scrape_multiple_sites(): async with AsyncDynamicSession( network_idle=True, timeout=30000, max_pages=3 ) as session: # Make async requests with shared browser configuration pages = await asyncio.gather( session.fetch('https://spa-app1.com'), session.fetch('https://spa-app2.com'), session.fetch('https://dynamic-content.com') ) return pages ``` You may have noticed the `max_pages` argument. This is a new argument that enables the fetcher to create a **rotating pool of Browser tabs**. Instead of using a single tab for all your requests, you set a limit on the maximum number of pages that can be displayed at once. With each request, the library will close all tabs that have finished their task and check if the number of the current tabs is lower than the maximum allowed number of pages/tabs, then: 1. If you are within the allowed range, the fetcher will create a new tab for you, and then all is as normal. 2. Otherwise, it will keep checking every subsecond if creating a new tab is allowed or not for 60 seconds, then raise `TimeoutError`. This can happen when the website you are fetching becomes unresponsive. This logic allows for multiple URLs to be fetched at the same time in the same browser, which saves a lot of resources, but most importantly, is so fast :) In versions 0.3 and 0.3.1, the pool was reusing finished tabs to save more resources/time. That logic proved flawed, as it's nearly impossible to protect pages/tabs from contamination by the previous configuration used in the request before this one. ### Session Benefits - **Browser reuse**: Much faster subsequent requests by reusing the same browser instance. - **Cookie persistence**: Automatic cookie and session state handling as any browser does automatically. - **Consistent fingerprint**: Same browser fingerprint across all requests. - **Memory efficiency**: Better resource usage compared to launching new browsers with each fetch. ## When to Use Use DynamicFetcher when: - Need browser automation - Want multiple browser options - Using a real Chrome browser - Need custom browser config - Want a few stealth options If you want more stealth and control without much config, check out the [StealthyFetcher](stealthy.md). ================================================ FILE: agent-skill/Scrapling-Skill/references/fetching/static.md ================================================ # HTTP requests The `Fetcher` class provides rapid and lightweight HTTP requests using the high-performance `curl_cffi` library with a lot of stealth capabilities. ## Basic Usage Import the Fetcher (same import pattern for all fetchers): ```python >>> from scrapling.fetchers import Fetcher ``` Check out how to configure the parsing options [here](choosing.md#parser-configuration-in-all-fetchers) ### Shared arguments All methods for making requests here share some arguments, so let's discuss them first. - **url**: The targeted URL - **stealthy_headers**: If enabled (default), it creates and adds real browser headers. It also sets a Google referer header. - **follow_redirects**: As the name implies, tell the fetcher to follow redirections. **Enabled by default** - **timeout**: The number of seconds to wait for each request to be finished. **Defaults to 30 seconds**. - **retries**: The number of retries that the fetcher will do for failed requests. **Defaults to three retries**. - **retry_delay**: Number of seconds to wait between retry attempts. **Defaults to 1 second**. - **impersonate**: Impersonate specific browsers' TLS fingerprints. Accepts browser strings or a list of them like `"chrome110"`, `"firefox102"`, `"safari15_5"` to use specific versions or `"chrome"`, `"firefox"`, `"safari"`, `"edge"` to automatically use the latest version available. This makes your requests appear to come from real browsers at the TLS level. If you pass it a list of strings, it will choose a random one with each request. **Defaults to the latest available Chrome version.** - **http3**: Use HTTP/3 protocol for requests. **Defaults to False**. It might be problematic if used with `impersonate`. - **cookies**: Cookies to use in the request. Can be a dictionary of `name→value` or a list of dictionaries. - **proxy**: As the name implies, the proxy for this request is used to route all traffic (HTTP and HTTPS). The format accepted here is `http://username:password@localhost:8030`. - **proxy_auth**: HTTP basic auth for proxy, tuple of (username, password). - **proxies**: Dict of proxies to use. Format: `{"http": proxy_url, "https": proxy_url}`. - **proxy_rotator**: A `ProxyRotator` instance for automatic proxy rotation. Cannot be combined with `proxy` or `proxies`. - **headers**: Headers to include in the request. Can override any header generated by the `stealthy_headers` argument - **max_redirects**: Maximum number of redirects. **Defaults to 30**, use -1 for unlimited. - **verify**: Whether to verify HTTPS certificates. **Defaults to True**. - **cert**: Tuple of (cert, key) filenames for the client certificate. - **selector_config**: A dictionary of custom parsing arguments to be used when creating the final `Selector`/`Response` class. **Notes:** 1. The currently available browsers to impersonate are (`"edge"`, `"chrome"`, `"chrome_android"`, `"safari"`, `"safari_beta"`, `"safari_ios"`, `"safari_ios_beta"`, `"firefox"`, `"tor"`) 2. The available browsers to impersonate, along with their corresponding versions, are automatically displayed in the argument autocompletion and updated with each `curl_cffi` update. 3. If any of the arguments `impersonate` or `stealthy_headers` are enabled, the fetchers will automatically generate real browser headers that match the browser version used. Other than this, for further customization, you can pass any arguments that `curl_cffi` supports for any method if that method doesn't already support them. ### HTTP Methods There are additional arguments for each method, depending on the method, such as `params` for GET requests and `data`/`json` for POST/PUT/DELETE requests. Examples are the best way to explain this: > Hence: `OPTIONS` and `HEAD` methods are not supported. #### GET ```python >>> from scrapling.fetchers import Fetcher >>> # Basic GET >>> page = Fetcher.get('https://example.com') >>> page = Fetcher.get('https://scrapling.requestcatcher.com/get', stealthy_headers=True, follow_redirects=True) >>> page = Fetcher.get('https://scrapling.requestcatcher.com/get', proxy='http://username:password@localhost:8030') >>> # With parameters >>> page = Fetcher.get('https://example.com/search', params={'q': 'query'}) >>> >>> # With headers >>> page = Fetcher.get('https://example.com', headers={'User-Agent': 'Custom/1.0'}) >>> # Basic HTTP authentication >>> page = Fetcher.get("https://example.com", auth=("my_user", "password123")) >>> # Browser impersonation >>> page = Fetcher.get('https://example.com', impersonate='chrome') >>> # HTTP/3 support >>> page = Fetcher.get('https://example.com', http3=True) ``` And for asynchronous requests, it's a small adjustment ```python >>> from scrapling.fetchers import AsyncFetcher >>> # Basic GET >>> page = await AsyncFetcher.get('https://example.com') >>> page = await AsyncFetcher.get('https://scrapling.requestcatcher.com/get', stealthy_headers=True, follow_redirects=True) >>> page = await AsyncFetcher.get('https://scrapling.requestcatcher.com/get', proxy='http://username:password@localhost:8030') >>> # With parameters >>> page = await AsyncFetcher.get('https://example.com/search', params={'q': 'query'}) >>> >>> # With headers >>> page = await AsyncFetcher.get('https://example.com', headers={'User-Agent': 'Custom/1.0'}) >>> # Basic HTTP authentication >>> page = await AsyncFetcher.get("https://example.com", auth=("my_user", "password123")) >>> # Browser impersonation >>> page = await AsyncFetcher.get('https://example.com', impersonate='chrome110') >>> # HTTP/3 support >>> page = await AsyncFetcher.get('https://example.com', http3=True) ``` The `page` object in all cases is a [Response](choosing.md#response-object) object, which is a [Selector](parsing/main_classes.md#selector), so you can use it directly ```python >>> page.css('.something.something') >>> page = Fetcher.get('https://api.github.com/events') >>> page.json() [{'id': '', 'type': 'PushEvent', 'actor': {'id': '', 'login': '', 'display_login': '', 'gravatar_id': '', 'url': 'https://api.github.com/users/', 'avatar_url': 'https://avatars.githubusercontent.com/u/'}, 'repo': {'id': '', ... ``` #### POST ```python >>> from scrapling.fetchers import Fetcher >>> # Basic POST >>> page = Fetcher.post('https://scrapling.requestcatcher.com/post', data={'key': 'value'}, params={'q': 'query'}) >>> page = Fetcher.post('https://scrapling.requestcatcher.com/post', data={'key': 'value'}, stealthy_headers=True, follow_redirects=True) >>> page = Fetcher.post('https://scrapling.requestcatcher.com/post', data={'key': 'value'}, proxy='http://username:password@localhost:8030', impersonate="chrome") >>> # Another example of form-encoded data >>> page = Fetcher.post('https://example.com/submit', data={'username': 'user', 'password': 'pass'}, http3=True) >>> # JSON data >>> page = Fetcher.post('https://example.com/api', json={'key': 'value'}) ``` And for asynchronous requests, it's a small adjustment ```python >>> from scrapling.fetchers import AsyncFetcher >>> # Basic POST >>> page = await AsyncFetcher.post('https://scrapling.requestcatcher.com/post', data={'key': 'value'}) >>> page = await AsyncFetcher.post('https://scrapling.requestcatcher.com/post', data={'key': 'value'}, stealthy_headers=True, follow_redirects=True) >>> page = await AsyncFetcher.post('https://scrapling.requestcatcher.com/post', data={'key': 'value'}, proxy='http://username:password@localhost:8030', impersonate="chrome") >>> # Another example of form-encoded data >>> page = await AsyncFetcher.post('https://example.com/submit', data={'username': 'user', 'password': 'pass'}, http3=True) >>> # JSON data >>> page = await AsyncFetcher.post('https://example.com/api', json={'key': 'value'}) ``` #### PUT ```python >>> from scrapling.fetchers import Fetcher >>> # Basic PUT >>> page = Fetcher.put('https://example.com/update', data={'status': 'updated'}) >>> page = Fetcher.put('https://example.com/update', data={'status': 'updated'}, stealthy_headers=True, follow_redirects=True, impersonate="chrome") >>> page = Fetcher.put('https://example.com/update', data={'status': 'updated'}, proxy='http://username:password@localhost:8030') >>> # Another example of form-encoded data >>> page = Fetcher.put("https://scrapling.requestcatcher.com/put", data={'key': ['value1', 'value2']}) ``` And for asynchronous requests, it's a small adjustment ```python >>> from scrapling.fetchers import AsyncFetcher >>> # Basic PUT >>> page = await AsyncFetcher.put('https://example.com/update', data={'status': 'updated'}) >>> page = await AsyncFetcher.put('https://example.com/update', data={'status': 'updated'}, stealthy_headers=True, follow_redirects=True, impersonate="chrome") >>> page = await AsyncFetcher.put('https://example.com/update', data={'status': 'updated'}, proxy='http://username:password@localhost:8030') >>> # Another example of form-encoded data >>> page = await AsyncFetcher.put("https://scrapling.requestcatcher.com/put", data={'key': ['value1', 'value2']}) ``` #### DELETE ```python >>> from scrapling.fetchers import Fetcher >>> page = Fetcher.delete('https://example.com/resource/123') >>> page = Fetcher.delete('https://example.com/resource/123', stealthy_headers=True, follow_redirects=True, impersonate="chrome") >>> page = Fetcher.delete('https://example.com/resource/123', proxy='http://username:password@localhost:8030') ``` And for asynchronous requests, it's a small adjustment ```python >>> from scrapling.fetchers import AsyncFetcher >>> page = await AsyncFetcher.delete('https://example.com/resource/123') >>> page = await AsyncFetcher.delete('https://example.com/resource/123', stealthy_headers=True, follow_redirects=True, impersonate="chrome") >>> page = await AsyncFetcher.delete('https://example.com/resource/123', proxy='http://username:password@localhost:8030') ``` ## Session Management For making multiple requests with the same configuration, use the `FetcherSession` class. It can be used in both synchronous and asynchronous code without issue; the class automatically detects and changes the session type, without requiring a different import. The `FetcherSession` class can accept nearly all the arguments that the methods can take, which enables you to specify a config for the entire session and later choose a different config for one of the requests effortlessly, as you will see in the following examples. ```python from scrapling.fetchers import FetcherSession # Create a session with default configuration with FetcherSession( impersonate='chrome', http3=True, stealthy_headers=True, timeout=30, retries=3 ) as session: # Make multiple requests with the same settings and the same cookies page1 = session.get('https://scrapling.requestcatcher.com/get') page2 = session.post('https://scrapling.requestcatcher.com/post', data={'key': 'value'}) page3 = session.get('https://api.github.com/events') # All requests share the same session and connection pool ``` You can also use a `ProxyRotator` with `FetcherSession` for automatic proxy rotation across requests: ```python from scrapling.fetchers import FetcherSession, ProxyRotator rotator = ProxyRotator([ 'http://proxy1:8080', 'http://proxy2:8080', 'http://proxy3:8080', ]) with FetcherSession(proxy_rotator=rotator, impersonate='chrome') as session: # Each request automatically uses the next proxy in rotation page1 = session.get('https://example.com/page1') page2 = session.get('https://example.com/page2') # You can check which proxy was used via the response metadata print(page1.meta['proxy']) ``` You can also override the session proxy (or rotator) for a specific request by passing `proxy=` directly to the request method: ```python with FetcherSession(proxy='http://default-proxy:8080') as session: # Uses the session proxy page1 = session.get('https://example.com/page1') # Override the proxy for this specific request page2 = session.get('https://example.com/page2', proxy='http://special-proxy:9090') ``` And here's an async example ```python async with FetcherSession(impersonate='firefox', http3=True) as session: # All standard HTTP methods available response = await session.get('https://example.com') response = await session.post('https://scrapling.requestcatcher.com/post', json={'data': 'value'}) response = await session.put('https://scrapling.requestcatcher.com/put', data={'update': 'info'}) response = await session.delete('https://scrapling.requestcatcher.com/delete') ``` or better ```python import asyncio from scrapling.fetchers import FetcherSession # Async session usage async with FetcherSession(impersonate="safari") as session: urls = ['https://example.com/page1', 'https://example.com/page2'] tasks = [ session.get(url) for url in urls ] pages = await asyncio.gather(*tasks) ``` The `Fetcher` class uses `FetcherSession` to create a temporary session with each request you make. ### Session Benefits - **A lot faster**: 10 times faster than creating a single session for each request - **Cookie persistence**: Automatic cookie handling across requests - **Resource efficiency**: Better memory and CPU usage for multiple requests - **Centralized configuration**: Single place to manage request settings ## Examples Some well-rounded examples to aid newcomers to Web Scraping ### Basic HTTP Request ```python from scrapling.fetchers import Fetcher # Make a request page = Fetcher.get('https://example.com') # Check the status if page.status == 200: # Extract title title = page.css('title::text').get() print(f"Page title: {title}") # Extract all links links = page.css('a::attr(href)').getall() print(f"Found {len(links)} links") ``` ### Product Scraping ```python from scrapling.fetchers import Fetcher def scrape_products(): page = Fetcher.get('https://example.com/products') # Find all product elements products = page.css('.product') results = [] for product in products: results.append({ 'title': product.css('.title::text').get(), 'price': product.css('.price::text').re_first(r'\d+\.\d{2}'), 'description': product.css('.description::text').get(), 'in_stock': product.has_class('in-stock') }) return results ``` ### Downloading Files ```python from scrapling.fetchers import Fetcher page = Fetcher.get('https://raw.githubusercontent.com/D4Vinci/Scrapling/main/images/main_cover.png') with open(file='main_cover.png', mode='wb') as f: f.write(page.body) ``` ### Pagination Handling ```python from scrapling.fetchers import Fetcher def scrape_all_pages(): base_url = 'https://example.com/products?page={}' page_num = 1 all_products = [] while True: # Get current page page = Fetcher.get(base_url.format(page_num)) # Find products products = page.css('.product') if not products: break # Process products for product in products: all_products.append({ 'name': product.css('.name::text').get(), 'price': product.css('.price::text').get() }) # Next page page_num += 1 return all_products ``` ### Form Submission ```python from scrapling.fetchers import Fetcher # Submit login form response = Fetcher.post( 'https://example.com/login', data={ 'username': 'user@example.com', 'password': 'password123' } ) # Check login success if response.status == 200: # Extract user info user_name = response.css('.user-name::text').get() print(f"Logged in as: {user_name}") ``` ### Table Extraction ```python from scrapling.fetchers import Fetcher def extract_table(): page = Fetcher.get('https://example.com/data') # Find table table = page.css('table')[0] # Extract headers headers = [ th.text for th in table.css('thead th') ] # Extract rows rows = [] for row in table.css('tbody tr'): cells = [td.text for td in row.css('td')] rows.append(dict(zip(headers, cells))) return rows ``` ### Navigation Menu ```python from scrapling.fetchers import Fetcher def extract_menu(): page = Fetcher.get('https://example.com') # Find navigation nav = page.css('nav')[0] menu = {} for item in nav.css('li'): links = item.css('a') if links: link = links[0] menu[link.text] = { 'url': link['href'], 'has_submenu': bool(item.css('.submenu')) } return menu ``` ## When to Use Use `Fetcher` when: - Need rapid HTTP requests. - Want minimal overhead. - Don't need JavaScript execution (the website can be scraped through requests). - Need some stealth features (ex, the targeted website is using protection but doesn't use JavaScript challenges). Use `FetcherSession` when: - Making multiple requests to the same or different sites. - Need to maintain cookies/authentication between requests. - Want connection pooling for better performance. - Require consistent configuration across requests. - Working with APIs that require a session state. Use other fetchers when: - Need browser automation. - Need advanced anti-bot/stealth capabilities. - Need JavaScript support or interacting with dynamic content ================================================ FILE: agent-skill/Scrapling-Skill/references/fetching/stealthy.md ================================================ # StealthyFetcher `StealthyFetcher` is a stealthy browser-based fetcher similar to [DynamicFetcher](dynamic.md), using [Playwright's API](https://playwright.dev/python/docs/intro). It adds advanced anti-bot protection bypass capabilities, most handled automatically. It shares the same browser automation model as `DynamicFetcher`, using [Playwright's Page API](https://playwright.dev/python/docs/api/class-page) for page interaction. ## Basic Usage You have one primary way to import this Fetcher, which is the same for all fetchers. ```python >>> from scrapling.fetchers import StealthyFetcher ``` Check out how to configure the parsing options [here](choosing.md#parser-configuration-in-all-fetchers) **Note:** The async version of the `fetch` method is `async_fetch`. ## What does it do? The `StealthyFetcher` class is a stealthy version of the [DynamicFetcher](dynamic.md) class, and here are some of the things it does: 1. It easily bypasses all types of Cloudflare's Turnstile/Interstitial automatically. 2. It bypasses CDP runtime leaks and WebRTC leaks. 3. It isolates JS execution, removes many Playwright fingerprints, and stops detection through some of the known behaviors that bots do. 4. It generates canvas noise to prevent fingerprinting through canvas. 5. It automatically patches known methods to detect running in headless mode and provides an option to defeat timezone mismatch attacks. 6. and other anti-protection options... ## Full list of arguments Scrapling provides many options with this fetcher and its session classes. Before jumping to the [examples](#examples), here's the full list of arguments | Argument | Description | Optional | |:-------------------:|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|:--------:| | url | Target url | ❌ | | headless | Pass `True` to run the browser in headless/hidden (**default**) or `False` for headful/visible mode. | ✔️ | | disable_resources | Drop requests for unnecessary resources for a speed boost. Requests dropped are of type `font`, `image`, `media`, `beacon`, `object`, `imageset`, `texttrack`, `websocket`, `csp_report`, and `stylesheet`. | ✔️ | | cookies | Set cookies for the next request. | ✔️ | | useragent | Pass a useragent string to be used. **Otherwise, the fetcher will generate and use a real Useragent of the same browser and version.** | ✔️ | | network_idle | Wait for the page until there are no network connections for at least 500 ms. | ✔️ | | load_dom | Enabled by default, wait for all JavaScript on page(s) to fully load and execute (wait for the `domcontentloaded` state). | ✔️ | | timeout | The timeout (milliseconds) used in all operations and waits through the page. The default is 30,000 ms (30 seconds). | ✔️ | | wait | The time (milliseconds) the fetcher will wait after everything finishes before closing the page and returning the `Response` object. | ✔️ | | page_action | Added for automation. Pass a function that takes the `page` object and does the necessary automation. | ✔️ | | wait_selector | Wait for a specific css selector to be in a specific state. | ✔️ | | init_script | An absolute path to a JavaScript file to be executed on page creation for all pages in this session. | ✔️ | | wait_selector_state | Scrapling will wait for the given state to be fulfilled for the selector given with `wait_selector`. _Default state is `attached`._ | ✔️ | | google_search | Enabled by default, Scrapling will set a Google referer header. | ✔️ | | extra_headers | A dictionary of extra headers to add to the request. _The referer set by `google_search` takes priority over the referer set here if used together._ | ✔️ | | proxy | The proxy to be used with requests. It can be a string or a dictionary with only the keys 'server', 'username', and 'password'. | ✔️ | | real_chrome | If you have a Chrome browser installed on your device, enable this, and the Fetcher will launch and use an instance of your browser. | ✔️ | | locale | Specify user locale, for example, `en-GB`, `de-DE`, etc. Locale will affect `navigator.language` value, `Accept-Language` request header value, as well as number and date formatting rules. Defaults to the system default locale. | ✔️ | | timezone_id | Changes the timezone of the browser. Defaults to the system timezone. | ✔️ | | cdp_url | Instead of launching a new browser instance, connect to this CDP URL to control real browsers through CDP. | ✔️ | | user_data_dir | Path to a User Data Directory, which stores browser session data like cookies and local storage. The default is to create a temporary directory. **Only Works with sessions** | ✔️ | | extra_flags | A list of additional browser flags to pass to the browser on launch. | ✔️ | | solve_cloudflare | When enabled, fetcher solves all types of Cloudflare's Turnstile/Interstitial challenges before returning the response to you. | ✔️ | | block_webrtc | Forces WebRTC to respect proxy settings to prevent local IP address leak. | ✔️ | | hide_canvas | Add random noise to canvas operations to prevent fingerprinting. | ✔️ | | allow_webgl | Enabled by default. Disabling it disables WebGL and WebGL 2.0 support entirely. Disabling WebGL is not recommended, as many WAFs now check if WebGL is enabled. | ✔️ | | additional_args | Additional arguments to be passed to Playwright's context as additional settings, and they take higher priority than Scrapling's settings. | ✔️ | | selector_config | A dictionary of custom parsing arguments to be used when creating the final `Selector`/`Response` class. | ✔️ | | blocked_domains | A set of domain names to block requests to. Subdomains are also matched (e.g., `"example.com"` blocks `"sub.example.com"` too). | ✔️ | | proxy_rotator | A `ProxyRotator` instance for automatic proxy rotation. Cannot be combined with `proxy`. | ✔️ | | retries | Number of retry attempts for failed requests. Defaults to 3. | ✔️ | | retry_delay | Seconds to wait between retry attempts. Defaults to 1. | ✔️ | In session classes, all these arguments can be set globally for the session. Still, you can configure each request individually by passing some of the arguments here that can be configured on the browser tab level like: `google_search`, `timeout`, `wait`, `page_action`, `extra_headers`, `disable_resources`, `wait_selector`, `wait_selector_state`, `network_idle`, `load_dom`, `solve_cloudflare`, `blocked_domains`, `proxy`, and `selector_config`. **Notes:** 1. It's basically the same arguments as [DynamicFetcher](dynamic.md) class, but with these additional arguments: `solve_cloudflare`, `block_webrtc`, `hide_canvas`, and `allow_webgl`. 2. The `disable_resources` option made requests ~25% faster in tests for some websites and can help save proxy usage, but be careful with it, as it can cause some websites to never finish loading. 3. The `google_search` argument is enabled by default for all requests, setting the referer to `https://www.google.com/`. If used together with `extra_headers`, it takes priority over the referer set there. 4. If you didn't set a user agent and enabled headless mode, the fetcher will generate a real user agent for the same browser version and use it. If you didn't set a user agent and didn't enable headless mode, the fetcher will use the browser's default user agent, which is the same as in standard browsers in the latest versions. ## Examples ### Cloudflare and stealth options ```python # Automatic Cloudflare solver page = StealthyFetcher.fetch('https://nopecha.com/demo/cloudflare', solve_cloudflare=True) # Works with other stealth options page = StealthyFetcher.fetch( 'https://protected-site.com', solve_cloudflare=True, block_webrtc=True, real_chrome=True, hide_canvas=True, google_search=True, proxy='http://username:password@host:port', # It can also be a dictionary with only the keys 'server', 'username', and 'password'. ) ``` The `solve_cloudflare` parameter enables automatic detection and solving all types of Cloudflare's Turnstile/Interstitial challenges: - JavaScript challenges (managed) - Interactive challenges (clicking verification boxes) - Invisible challenges (automatic background verification) And even solves the custom pages with embedded captcha. **Important notes:** 1. Sometimes, with websites that use custom implementations, you will need to use `wait_selector` to make sure Scrapling waits for the real website content to be loaded after solving the captcha. Some websites can be the real definition of an edge case while we are trying to make the solver as generic as possible. 2. The timeout should be at least 60 seconds when using the Cloudflare solver for sufficient challenge-solving time. 3. This feature works seamlessly with proxies and other stealth options. ### Browser Automation This is where your knowledge about [Playwright's Page API](https://playwright.dev/python/docs/api/class-page) comes into play. The function you pass here takes the page object from Playwright's API, performs the desired action, and then the fetcher continues. This function is executed immediately after waiting for `network_idle` (if enabled) and before waiting for the `wait_selector` argument, allowing it to be used for purposes beyond automation. You can alter the page as you want. In the example below, I used the pages' [mouse events](https://playwright.dev/python/docs/api/class-mouse) to scroll the page with the mouse wheel, then move the mouse. ```python from playwright.sync_api import Page def scroll_page(page: Page): page.mouse.wheel(10, 0) page.mouse.move(100, 400) page.mouse.up() page = StealthyFetcher.fetch('https://example.com', page_action=scroll_page) ``` Of course, if you use the async fetch version, the function must also be async. ```python from playwright.async_api import Page async def scroll_page(page: Page): await page.mouse.wheel(10, 0) await page.mouse.move(100, 400) await page.mouse.up() page = await StealthyFetcher.async_fetch('https://example.com', page_action=scroll_page) ``` ### Wait Conditions ```python # Wait for the selector page = StealthyFetcher.fetch( 'https://example.com', wait_selector='h1', wait_selector_state='visible' ) ``` This is the last wait the fetcher will do before returning the response (if enabled). You pass a CSS selector to the `wait_selector` argument, and the fetcher will wait for the state you passed in the `wait_selector_state` argument to be fulfilled. If you didn't pass a state, the default would be `attached`, which means it will wait for the element to be present in the DOM. After that, if `load_dom` is enabled (the default), the fetcher will check again to see if all JavaScript files are loaded and executed (in the `domcontentloaded` state) or continue waiting. If you have enabled `network_idle`, the fetcher will wait for `network_idle` to be fulfilled again, as explained above. The states the fetcher can wait for can be any of the following ([source](https://playwright.dev/python/docs/api/class-page#page-wait-for-selector)): - `attached`: Wait for an element to be present in the DOM. - `detached`: Wait for an element to not be present in the DOM. - `visible`: wait for an element to have a non-empty bounding box and no `visibility:hidden`. Note that an element without any content or with `display:none` has an empty bounding box and is not considered visible. - `hidden`: wait for an element to be either detached from the DOM, or have an empty bounding box, or `visibility:hidden`. This is opposite to the `'visible'` option. ### Real-world example (Amazon) This is for educational purposes only; this example was generated by AI, which also shows how easy it is to work with Scrapling through AI ```python def scrape_amazon_product(url): # Use StealthyFetcher to bypass protection page = StealthyFetcher.fetch(url) # Extract product details return { 'title': page.css('#productTitle::text').get().clean(), 'price': page.css('.a-price .a-offscreen::text').get(), 'rating': page.css('[data-feature-name="averageCustomerReviews"] .a-popover-trigger .a-color-base::text').get(), 'reviews_count': page.css('#acrCustomerReviewText::text').re_first(r'[\d,]+'), 'features': [ li.get().clean() for li in page.css('#feature-bullets li span::text') ], 'availability': page.css('#availability')[0].get_all_text(strip=True), 'images': [ img.attrib['src'] for img in page.css('#altImages img') ] } ``` ## Session Management To keep the browser open until you make multiple requests with the same configuration, use `StealthySession`/`AsyncStealthySession` classes. Those classes can accept all the arguments that the `fetch` function can take, which enables you to specify a config for the entire session. ```python from scrapling.fetchers import StealthySession # Create a session with default configuration with StealthySession( headless=True, real_chrome=True, block_webrtc=True, solve_cloudflare=True ) as session: # Make multiple requests with the same browser instance page1 = session.fetch('https://example1.com') page2 = session.fetch('https://example2.com') page3 = session.fetch('https://nopecha.com/demo/cloudflare') # All requests reuse the same tab on the same browser instance ``` ### Async Session Usage ```python import asyncio from scrapling.fetchers import AsyncStealthySession async def scrape_multiple_sites(): async with AsyncStealthySession( real_chrome=True, block_webrtc=True, solve_cloudflare=True, timeout=60000, # 60 seconds for Cloudflare challenges max_pages=3 ) as session: # Make async requests with shared browser configuration pages = await asyncio.gather( session.fetch('https://site1.com'), session.fetch('https://site2.com'), session.fetch('https://protected-site.com') ) return pages ``` You may have noticed the `max_pages` argument. This is a new argument that enables the fetcher to create a **rotating pool of Browser tabs**. Instead of using a single tab for all your requests, you set a limit on the maximum number of pages that can be displayed at once. With each request, the library will close all tabs that have finished their task and check if the number of the current tabs is lower than the maximum allowed number of pages/tabs, then: 1. If you are within the allowed range, the fetcher will create a new tab for you, and then all is as normal. 2. Otherwise, it will keep checking every subsecond if creating a new tab is allowed or not for 60 seconds, then raise `TimeoutError`. This can happen when the website you are fetching becomes unresponsive. This logic allows for multiple URLs to be fetched at the same time in the same browser, which saves a lot of resources, but most importantly, is so fast :) In versions 0.3 and 0.3.1, the pool was reusing finished tabs to save more resources/time. That logic proved flawed, as it's nearly impossible to protect pages/tabs from contamination by the previous configuration used in the request before this one. ### Session Benefits - **Browser reuse**: Much faster subsequent requests by reusing the same browser instance. - **Cookie persistence**: Automatic cookie and session state handling as any browser does automatically. - **Consistent fingerprint**: Same browser fingerprint across all requests. - **Memory efficiency**: Better resource usage compared to launching new browsers with each fetch. ## When to Use Use StealthyFetcher when: - Bypassing anti-bot protection - Need a reliable browser fingerprint - Full JavaScript support needed - Want automatic stealth features - Need browser automation - Dealing with Cloudflare protection ================================================ FILE: agent-skill/Scrapling-Skill/references/mcp-server.md ================================================ # Scrapling MCP Server The Scrapling MCP server exposes six web scraping tools over the MCP protocol. It supports CSS-selector-based content narrowing (reducing tokens by extracting only relevant elements before returning results) and three levels of scraping capability: plain HTTP, browser-rendered, and stealth (anti-bot bypass). All tools return a `ResponseModel` with fields: `status` (int), `content` (list of strings), `url` (str). ## Tools ### `get` -- HTTP request (single URL) Fast HTTP GET with browser fingerprint impersonation (TLS, headers). Suitable for static pages with no/low bot protection. **Key parameters:** | Parameter | Type | Default | Description | |---------------------|------------------------------------|--------------|--------------------------------------------------------------------| | `url` | str | required | URL to fetch | | `extraction_type` | `"markdown"` / `"html"` / `"text"` | `"markdown"` | Output format | | `css_selector` | str or null | null | CSS selector to narrow content (applied after `main_content_only`) | | `main_content_only` | bool | true | Restrict to `` content | | `impersonate` | str | `"chrome"` | Browser fingerprint to impersonate | | `proxy` | str or null | null | Proxy URL, e.g. `"http://user:pass@host:port"` | | `proxy_auth` | dict or null | null | `{"username": "...", "password": "..."}` | | `auth` | dict or null | null | HTTP basic auth, same format as proxy_auth | | `timeout` | number | 30 | Seconds before timeout | | `retries` | int | 3 | Retry attempts on failure | | `retry_delay` | int | 1 | Seconds between retries | | `stealthy_headers` | bool | true | Generate realistic browser headers and Google referer | | `http3` | bool | false | Use HTTP/3 (may conflict with `impersonate`) | | `follow_redirects` | bool | true | Follow HTTP redirects | | `max_redirects` | int | 30 | Max redirects (-1 for unlimited) | | `headers` | dict or null | null | Custom request headers | | `cookies` | dict or null | null | Request cookies | | `params` | dict or null | null | Query string parameters | | `verify` | bool | true | Verify HTTPS certificates | ### `bulk_get` -- HTTP request (multiple URLs) Async concurrent version of `get`. Same parameters except `url` is replaced by `urls` (list of strings). All URLs are fetched in parallel. Returns a list of `ResponseModel`. ### `fetch` -- Browser fetch (single URL) Opens a Chromium browser via Playwright to render JavaScript. Suitable for dynamic/SPA pages with no/low bot protection. **Key parameters (beyond shared ones):** | Parameter | Type | Default | Description | |-----------------------|---------------------|--------------|---------------------------------------------------------------------------------| | `url` | str | required | URL to fetch | | `extraction_type` | str | `"markdown"` | `"markdown"` / `"html"` / `"text"` | | `css_selector` | str or null | null | Narrow content before extraction | | `main_content_only` | bool | true | Restrict to `` | | `headless` | bool | true | Run browser hidden (true) or visible (false) | | `proxy` | str or dict or null | null | String URL or `{"server": "...", "username": "...", "password": "..."}` | | `timeout` | number | 30000 | Timeout in **milliseconds** | | `wait` | number | 0 | Extra wait (ms) after page load before extraction | | `wait_selector` | str or null | null | CSS selector to wait for before extraction | | `wait_selector_state` | str | `"attached"` | State for wait_selector: `"attached"` / `"visible"` / `"hidden"` / `"detached"` | | `network_idle` | bool | false | Wait until no network activity for 500ms | | `disable_resources` | bool | false | Block fonts, images, media, stylesheets, etc. for speed | | `google_search` | bool | true | Set a Google referer header | | `real_chrome` | bool | false | Use locally installed Chrome instead of bundled Chromium | | `cdp_url` | str or null | null | Connect to existing browser via CDP URL | | `extra_headers` | dict or null | null | Additional request headers | | `useragent` | str or null | null | Custom user-agent (auto-generated if null) | | `cookies` | list or null | null | Playwright-format cookies | | `timezone_id` | str or null | null | Browser timezone, e.g. `"America/New_York"` | | `locale` | str or null | null | Browser locale, e.g. `"en-GB"` | ### `bulk_fetch` -- Browser fetch (multiple URLs) Concurrent browser version of `fetch`. Same parameters except `url` is replaced by `urls` (list of strings). Each URL opens in a separate browser tab. Returns a list of `ResponseModel`. ### `stealthy_fetch` -- Stealth browser fetch (single URL) Anti-bot bypass fetcher with fingerprint spoofing. Use this for sites with Cloudflare Turnstile/Interstitial or other strong protections. **Additional parameters (beyond those in `fetch`):** | Parameter | Type | Default | Description | |--------------------|--------------|---------|------------------------------------------------------------------| | `solve_cloudflare` | bool | false | Automatically solve Cloudflare Turnstile/Interstitial challenges | | `hide_canvas` | bool | false | Add noise to canvas operations to prevent fingerprinting | | `block_webrtc` | bool | false | Force WebRTC to respect proxy settings (prevents IP leak) | | `allow_webgl` | bool | true | Keep WebGL enabled (disabling is detectable by WAFs) | | `additional_args` | dict or null | null | Extra Playwright context args (overrides Scrapling defaults) | All parameters from `fetch` are also accepted. ### `bulk_stealthy_fetch` -- Stealth browser fetch (multiple URLs) Concurrent stealth version. Same parameters as `stealthy_fetch` except `url` is replaced by `urls` (list of strings). Returns a list of `ResponseModel`. ## Tool selection guide | Scenario | Tool | |------------------------------------------|---------------------------------------------------------------| | Static page, no bot protection | `get` | | Multiple static pages | `bulk_get` | | JavaScript-rendered / SPA page | `fetch` | | Multiple JS-rendered pages | `bulk_fetch` | | Cloudflare or strong anti-bot protection | `stealthy_fetch` (with `solve_cloudflare=true` for Turnstile) | | Multiple protected pages | `bulk_stealthy_fetch` | Start with `get` (fastest, lowest resource cost). Escalate to `fetch` if content requires JS rendering. Escalate to `stealthy_fetch` only if blocked. ## Content extraction tips - Use `css_selector` to narrow results before they reach the model -- this saves significant tokens. - `main_content_only=true` (default) strips nav/footer by restricting to ``. - `extraction_type="markdown"` (default) is best for readability. Use `"text"` for minimal output, `"html"` when structure matters. - If a `css_selector` matches multiple elements, all are returned in the `content` list. ## Setup Start the server (stdio transport, used by most MCP clients): ```bash scrapling mcp ``` Or with Streamable HTTP transport: ```bash scrapling mcp --http scrapling mcp --http --host 127.0.0.1 --port 8000 ``` Docker alternative: ```bash docker pull pyd4vinci/scrapling docker run -i --rm scrapling mcp ``` The MCP server name when registering with a client is `ScraplingServer`. The command is the path to the `scrapling` binary and the argument is `mcp`. ================================================ FILE: agent-skill/Scrapling-Skill/references/migrating_from_beautifulsoup.md ================================================ # Migrating from BeautifulSoup to Scrapling API comparison between BeautifulSoup and Scrapling.

Scrapling does not — it is read-only and optimized for extraction. ### Full Example: Extracting Links **With BeautifulSoup:** ```python import requests from bs4 import BeautifulSoup url = 'https://example.com' response = requests.get(url) soup = BeautifulSoup(response.text, 'html.parser') links = soup.find_all('a') for link in links: print(link['href']) ``` **With Scrapling:** ```python from scrapling import Fetcher url = 'https://example.com' page = Fetcher.get(url) links = page.css('a::attr(href)') for link in links: print(link) ``` Scrapling combines fetching and parsing into a single step. **Note:** - **Parsers**: BeautifulSoup supports multiple parser engines. Scrapling always uses `lxml` for performance. - **Element Types**: BeautifulSoup elements are `Tag` objects; Scrapling elements are `Selector` objects. Both provide similar navigation and extraction methods. - **Error Handling**: Both libraries return `None` when an element is not found (e.g., `soup.find()` or `page.find()`). `page.css()` returns an empty `Selectors` list when no elements match. Use `page.css('.foo').first` to safely get the first match or `None`. - **Text Extraction**: Scrapling's `TextHandler` provides additional text processing methods such as `clean()` for removing extra whitespace, consecutive spaces, or unwanted characters. ================================================ FILE: agent-skill/Scrapling-Skill/references/parsing/adaptive.md ================================================ # Adaptive scraping Adaptive scraping (previously known as automatch) is one of Scrapling's most powerful features. It allows your scraper to survive website changes by intelligently tracking and relocating elements. Consider a page with a structure like this: ```html

Product 1

Description 1

Product 2

Description 2

``` To scrape the first product (the one with the `p1` ID), a selector like this would be used: ```python page.css('#p1') ``` When website owners implement structural changes like ```html

Product 1

Description 1

Product 2

Description 2

``` The selector will no longer function, and your code needs maintenance. That's where Scrapling's `adaptive` feature comes into play. With Scrapling, you can enable the `adaptive` feature the first time you select an element, and the next time you select that element and it doesn't exist, Scrapling will remember its properties and search on the website for the element with the highest percentage of similarity to that element. ```python from scrapling import Selector, Fetcher # Before the change page = Selector(page_source, adaptive=True, url='example.com') # or Fetcher.adaptive = True page = Fetcher.get('https://example.com') # then element = page.css('#p1', auto_save=True) if not element: # One day website changes? element = page.css('#p1', adaptive=True) # Scrapling still finds it! # the rest of your code... ``` It works with all selection methods, not just CSS/XPath selection. ## Real-World Scenario This example uses [The Web Archive](https://archive.org/)'s [Wayback Machine](https://web.archive.org/) to demonstrate adaptive scraping across different versions of a website. A copy of [StackOverflow's website in 2010](https://web.archive.org/web/20100102003420/http://stackoverflow.com/) is compared against the current design to show that the adaptive feature can extract the same button using the same selector. To extract the Questions button from the old design, a selector like `#hmenus > div:nth-child(1) > ul > li:nth-child(1) > a` can be used (this specific selector was generated by Chrome). Testing the same selector in both versions: ```python >> from scrapling import Fetcher >> selector = '#hmenus > div:nth-child(1) > ul > li:nth-child(1) > a' >> old_url = "https://web.archive.org/web/20100102003420/http://stackoverflow.com/" >> new_url = "https://stackoverflow.com/" >> Fetcher.configure(adaptive = True, adaptive_domain='stackoverflow.com') >> >> page = Fetcher.get(old_url, timeout=30) >> element1 = page.css(selector, auto_save=True)[0] >> >> # Same selector but used in the updated website >> page = Fetcher.get(new_url) >> element2 = page.css(selector, adaptive=True)[0] >> >> if element1.text == element2.text: ... print('Scrapling found the same element in the old and new designs!') 'Scrapling found the same element in the old and new designs!' ``` The `adaptive_domain` argument is used here because Scrapling sees `archive.org` and `stackoverflow.com` as two different domains and would isolate their `adaptive` data. Passing `adaptive_domain` tells Scrapling to treat them as the same website for adaptive data storage. In a typical scenario with the same URL for both requests, the `adaptive_domain` argument is not needed. The adaptive logic works the same way with both the `Selector` and `Fetcher` classes. **Note:** The main reason for creating the `adaptive_domain` argument was to handle if the website changed its URL while changing the design/structure. In that case, it can be used to continue using the previously stored adaptive data for the new URL. Otherwise, Scrapling will consider it a new website and discard the old data. ## How the adaptive scraping feature works Adaptive scraping works in two phases: 1. **Save Phase**: Store unique properties of elements 2. **Match Phase**: Find elements with similar properties later After selecting an element through any method, the library can find it the next time the website is scraped, even if it undergoes structural/design changes. The general logic is as follows: 1. Scrapling saves that element's unique properties (methods shown below). 2. Scrapling uses its configured database (SQLite by default) and saves each element's unique properties. 3. Because everything about the element can be changed or removed by the website's owner(s), nothing from the element can be used as a unique identifier for the database. The storage system relies on two things: 1. The domain of the current website. When using the `Selector` class, pass it when initializing; when using a fetcher, the domain is automatically taken from the URL. 2. An `identifier` to query that element's properties from the database. The identifier does not always need to be set manually (see below). Together, they will later be used to retrieve the element's unique properties from the database. 4. Later, when the website's structure changes, enabling `adaptive` causes Scrapling to retrieve the element's unique properties and match all elements on the page against them. A score is calculated based on their similarity to the desired element. Everything is taken into consideration in that comparison. 5. The element(s) with the highest similarity score to the wanted element are returned. ### The unique properties The unique properties Scrapling relies on are: - Element tag name, text, attributes (names and values), siblings (tag names only), and path (tag names only). - Element's parent tag name, attributes (names and values), and text. The comparison between elements is not exact; it is based on how similar these values are. Everything is considered, including the values' order (e.g., the order in which class names are written). ## How to use adaptive feature The adaptive feature can be applied to any found element and is added as arguments to CSS/XPath selection methods. First, enable the `adaptive` feature by passing `adaptive=True` to the [Selector](main_classes.md#selector) class when initializing it, or enable it on the fetcher being used. Examples: ```python >>> from scrapling import Selector, Fetcher >>> page = Selector(html_doc, adaptive=True) # OR >>> Fetcher.adaptive = True >>> page = Fetcher.get('https://example.com') ``` When using the [Selector](main_classes.md#selector) class, pass the URL of the website with the `url` argument so Scrapling can separate the properties saved for each element by domain. If no URL is passed, the word `default` will be used in place of the URL field while saving the element's unique properties. This is only an issue when using the same identifier for a different website without passing the URL parameter. The save process overwrites previous data, and the `adaptive` feature uses only the latest saved properties. The `storage` and `storage_args` arguments control the database connection; by default, the SQLite class provided by the library is used. There are two main ways to use the `adaptive` feature: ### The CSS/XPath Selection way First, use the `auto_save` argument while selecting an element that exists on the page: ```python element = page.css('#p1', auto_save=True) ``` When the element no longer exists, use the same selector with the `adaptive` argument to have the library find it: ```python element = page.css('#p1', adaptive=True) ``` With the `css`/`xpath` methods, the identifier is set automatically to the selector string passed to the method. Additionally, for all these methods, you can pass the `identifier` argument to set it yourself. This is useful in some instances, or you can use it to save properties with the `auto_save` argument. ### The manual way Elements can be manually saved, retrieved, and relocated within the `adaptive` feature. This allows relocating any element found by any method. Example of getting an element by text: ```python >>> element = page.find_by_text('Tipping the Velvet', first_match=True) ``` Save its unique properties using the `save` method. The identifier must be set manually (use a meaningful identifier): ```python >>> page.save(element, 'my_special_element') ``` Later, retrieve and relocate the element inside the page with `adaptive`: ```python >>> element_dict = page.retrieve('my_special_element') >>> page.relocate(element_dict, selector_type=True) [] >>> page.relocate(element_dict, selector_type=True).css('::text').getall() ['Tipping the Velvet'] ``` The `retrieve` and `relocate` methods are used here. To keep it as a `lxml.etree` object, omit the `selector_type` argument: ```python >>> page.relocate(element_dict) [] ``` ## Troubleshooting ### No Matches Found ```python # 1. Check if data was saved element_data = page.retrieve('identifier') if not element_data: print("No data saved for this identifier") # 2. Try with different identifier products = page.css('.product', adaptive=True, identifier='old_selector') # 3. Save again with new identifier products = page.css('.new-product', auto_save=True, identifier='new_identifier') ``` ### Wrong Elements Matched ```python # Use more specific selectors products = page.css('.product-list .product', auto_save=True) # Or save with more context product = page.find_by_text('Product Name').parent page.save(product, 'specific_product') ``` ## Known Issues In the `adaptive` save process, only the unique properties of the first element in the selection results are saved. So if the selector you are using selects different elements on the page in other locations, `adaptive` 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 are separated and each is executed alone. ================================================ FILE: agent-skill/Scrapling-Skill/references/parsing/main_classes.md ================================================ # Parsing main classes The [Selector](#selector) class is the core parsing engine in Scrapling, providing HTML parsing and element selection capabilities. You can always import it with any of the following imports ```python from scrapling import Selector from scrapling.parser import Selector ``` Usage: ```python page = Selector( '...', url='https://example.com' ) # Then select elements as you like elements = page.css('.product') ``` In Scrapling, the main object you deal with after passing an HTML source or fetching a website is, of course, a [Selector](#selector) object. Any operation you do, like selection, navigation, etc., will return either a [Selector](#selector) object or a [Selectors](#selectors) object, given that the result is element/elements from the page, not text or similar. The main page is a [Selector](#selector) object, and the elements within are [Selector](#selector) objects. Any text (text content inside elements or attribute values) is a [TextHandler](#texthandler) object, and element attributes are stored as [AttributesHandler](#attributeshandler). ## Selector ### Arguments explained The most important one is `content`, it's used to pass the HTML code you want to parse, and it accepts the HTML content as `str` or `bytes`. The arguments `url`, `adaptive`, `storage`, and `storage_args` are settings used with the `adaptive` feature. They are explained in the [adaptive](adaptive.md) feature page. Arguments for parsing adjustments: - **encoding**: This is the encoding that will be used while parsing the HTML. The default is `UTF-8`. - **keep_comments**: This tells the library whether to keep HTML comments while parsing the page. It's disabled by default because it can cause issues with your scraping in various ways. - **keep_cdata**: Same logic as the HTML comments. [cdata](https://stackoverflow.com/questions/7092236/what-is-cdata-in-html) is removed by default for cleaner HTML. The arguments `huge_tree` and `root` are advanced features not covered here. Most properties on the main page and its elements are lazily loaded (not initialized until accessed), which contributes to Scrapling's speed. ### Properties Properties for traversal are separated in the [traversal](#traversal) section below.

``` Load the page directly as shown before: ```python from scrapling import Selector page = Selector(html_doc) ``` Get all text content on the page recursively ```python >>> page.get_all_text() 'Some page\n\n \n\n \nProduct 1\nThis is product 1\n$10.99\nIn stock: 5\nProduct 2\nThis is product 2\n$20.99\nIn stock: 3\nProduct 3\nThis is product 3\n$15.99\nOut of stock' ``` Get the first article (used as an example throughout): ```python article = page.find('article') ``` With the same logic, get all text content on the element recursively ```python >>> article.get_all_text() 'Product 1\nThis is product 1\n$10.99\nIn stock: 5' ``` But if you try to get the direct text content, it will be empty because it doesn't have direct text in the HTML code above ```python >>> article.text '' ``` The `get_all_text` method has the following optional arguments: 1. **separator**: All strings collected will be concatenated using this separator. The default is '\n'. 2. **strip**: If enabled, strings will be stripped before concatenation. Disabled by default. 3. **ignore_tags**: A tuple of all tag names you want to ignore in the final results and ignore any elements nested within them. The default is `('script', 'style',)`. 4. **valid_values**: If enabled, the method will only collect elements with real values, so all elements with empty text content or only whitespaces will be ignored. It's enabled by default The text returned is a [TextHandler](#texthandler), not a standard string. If the text content can be serialized to JSON, use `.json()` on it: ```python >>> script = page.find('script') >>> script.json() {'lastUpdated': '2024-09-22T10:30:00Z', 'totalProducts': 3} ``` Let's continue to get the element tag ```python >>> article.tag 'article' ``` Using it on the page directly operates on the root `html` element: ```python >>> page.tag 'html' ``` Getting the attributes of the element ```python >>> print(article.attrib) {'class': 'product', 'data-id': '1'} ``` Access a specific attribute with any of the following ```python >>> article.attrib['class'] >>> article.attrib.get('class') >>> article['class'] # new in v0.3 ``` Check if the attributes contain a specific attribute with any of the methods below ```python >>> 'class' in article.attrib >>> 'class' in article # new in v0.3 ``` Get the HTML content of the element ```python >>> article.html_content '

The `html` element is the root of the website's tree. Elements like `head` and `body` are "children" of `html`, and `html` is their "parent". The element `body` is a "sibling" of `head` and vice versa. Accessing the parent of an element ```python >>> article.parent
>>> article.parent.tag 'div' ``` Chaining is supported, as with all similar properties/methods: ```python >>> article.parent.parent.tag 'body' ``` Get the children of an element ```python >>> article.children [Product 1' parent='
