# 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                                                                                                                                    |

Options shared between `post` and `put` only:

| Option     | Input type | Description                                                                             |
|:-----------|:----------:|:----------------------------------------------------------------------------------------|
| -d, --data |    TEXT    | Form data to include in the request body (as string, ex: "param1=value1&param2=value2") |
| -j, --json |    TEXT    | JSON data to include in the request body (as string)                                    |

Examples:

# Wait for JavaScript to load content and finish network activity
scrapling extract fetch "https://scrapling.requestcatcher.com/" content.md --network-idle

# Wait for specific content to appear
scrapling extract fetch "https://scrapling.requestcatcher.com/" data.txt --wait-selector ".content-loaded"

# Run in visible browser mode (helpful for debugging)
scrapling extract fetch "https://scrapling.requestcatcher.com/" page.html --no-headless --disable-resources

# Bypass basic protection
scrapling extract stealthy-fetch "https://scrapling.requestcatcher.com" content.md

# Solve Cloudflare challenges
scrapling extract stealthy-fetch "https://nopecha.com/demo/cloudflare" data.txt --solve-cloudflare --css-selector "#padded_content a"

# Use a proxy for anonymity.
scrapling extract stealthy-fetch "https://site.com" content.md --proxy "http://proxy-server:8080"
```


### Notes

- ALWAYS clean up temp files after reading
- Prefer `.md` output for readability; use `.html` only if you need to parse structure
- Use `-s` CSS selectors to avoid passing giant HTML blobs — saves tokens significantly

## Code overview

Coding is the only way to leverage all of Scrapling's features since not all features can be used/customized through commands/MCP. 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("<html>...</html>")
```
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())
```

This skill encapsulates almost all the published documentation in Markdown, so don't check external sources or search online without the user's permission.

## Guardrails (Always)
- Only scrape content you're authorized to access.
- Respect robots.txt and ToS.
- Add delays (download_delay) for large crawls.
- Don't bypass paywalls or authentication without permission.
- Never scrape personal/sensitive data.
