7. Using Hooks for Custom Workflow

Hooks in Crawl4AI allow you to run custom logic at specific stages of the crawling process. This can be invaluable for scenarios like setting custom headers, logging activities, or processing content before it is returned. Below is an example of a basic workflow using a hook, followed by a complete list of available hooks and explanations on their usage.

In [ ]:

async def custom_hook_workflow():
    async with AsyncWebCrawler() as crawler:
        # Set a 'before_goto' hook to run custom code just before navigation
        crawler.crawler_strategy.set_hook("before_goto", lambda page: print("[Hook] Preparing to navigate..."))
        
        # Perform the crawl operation
        result = await crawler.arun(
            url="https://crawl4ai.com",
            bypass_cache=True
        )
        print(result.markdown.raw_markdown[:500])  # Display the first 500 characters

asyncio.run(custom_hook_workflow())

      print("[Hook] Browser created")
  

• before_goto

  async def before_goto_hook(page):
      await page.set_extra_http_headers({"X-Test-Header": "test"})

• before_return_html

  async def before_return_html_hook(page, html):
      print(f"[Hook] HTML length: {len(html)}")
  

8. Session-Based Crawling

When to Use Session-Based Crawling: Session-based crawling is especially beneficial when navigating through multi-page content where each page load needs to maintain the same session context. For instance, in cases where a “Next Page” button must be clicked to load subsequent data, the new data often replaces the previous content. Here, session-based crawling keeps the browser state intact across each interaction, allowing for sequential actions within the same session.

Example: Multi-Page Navigation Using JavaScript In this example, we’ll navigate through multiple pages by clicking a "Next Page" button. After each page load, we extract the new content and repeat the process.

In [ ]:

async def multi_page_session_crawl():
    async with AsyncWebCrawler() as crawler:
        session_id = "page_navigation_session"
        url = "https://example.com/paged-content"

        for page_number in range(1, 4):
            result = await crawler.arun(
                url=url,
                session_id=session_id,
                js_code="document.querySelector('.next-page-button').click();" if page_number > 1 else None,
                css_selector=".content-section",
                bypass_cache=True
            )
            print(f"Page {page_number} Content:")
            print(result.markdown.raw_markdown[:500])  # Print first 500 characters

# asyncio.run(multi_page_session_crawl())

9. Using Extraction Strategies

LLM Extraction

This example demonstrates how to use language model-based extraction to retrieve structured data from a pricing page on OpenAI’s site.

In [31]:

from crawl4ai.extraction_strategy import LLMExtractionStrategy
from pydantic import BaseModel, Field
import os, json

class OpenAIModelFee(BaseModel):
    model_name: str = Field(..., description="Name of the OpenAI model.")
    input_fee: str = Field(..., description="Fee for input token for the OpenAI model.")
    output_fee: str = Field(
        ..., description="Fee for output token for the OpenAI model."
    )

async def extract_structured_data_using_llm(provider: str, api_token: str = None, extra_headers: dict = None):
    print(f"\n--- Extracting Structured Data with {provider} ---")
    
    # Skip if API token is missing (for providers that require it)
    if api_token is None and provider != "ollama":
        print(f"API token is required for {provider}. Skipping this example.")
        return

    extra_args = {"extra_headers": extra_headers} if extra_headers else {}

    async with AsyncWebCrawler(verbose=True) as crawler:
        result = await crawler.arun(
            url="https://openai.com/api/pricing/",
            word_count_threshold=1,
            extraction_strategy=LLMExtractionStrategy(
                provider=provider,
                api_token=api_token,
                schema=OpenAIModelFee.schema(),
                extraction_type="schema",
                instruction="""Extract all model names along with fees for input and output tokens."
                "{model_name: 'GPT-4', input_fee: 'US$10.00 / 1M tokens', output_fee: 'US$30.00 / 1M tokens'}.""",
                **extra_args
            ),
            bypass_cache=True,
        )
        print(json.loads(result.extracted_content)[:5])

# Usage:
await extract_structured_data_using_llm("openai/gpt-4o-mini", os.getenv("OPENAI_API_KEY"))

Still, the U.S. had repeatedly dodged a much-forecast recession, and [Americans kept spending on nonessentials](https://www.nbcnews.com/business/economy/year-peak-inflation-travel-leisure-mostly-cost-less-rcna92760) like travel and dining out — despite regularly relaying to pollsters their dismal views of an otherwise solid economy. Even so, 64% of consumers said they noticed price increases at quick-service restaurants in September, more than at any other type of venue, according to a survey by Datassential, a food and beverage market researcher. Politicians are still drawing attention to fast-food costs, too, as the election season barrels toward a tumultuous finish. A group of Democratic senators this month [denounced McDonald’s for menu prices](https://www.nbcnews.com/news/us-news/democratic-senators-slam-mcdonalds-menu-price-hikes-rcna176380) that they said outstripped inflation, accusing the company of looking to profit “at the expense of people’s ability to put food on the table.” The financial results come toward the end of a humbling year for the nearly $213 billion restaurant chain, whose shares remained steady on the heels of its latest earnings. Kempczinski [sought to reassure investors](https://www.cnbc.com/2024/10/29/mcdonalds-e-coli-outbreak-ceo-comments.html) that [the E. coli outbreak](https://www.nbcnews.com/health/health-news/illnesses-linked-mcdonalds-e-coli-outbreak-rise-75-cdc-says-rcna177260), linked to Quarter Pounder burgers, was under control after the health crisis temporarily dented the company’s stock and caused U.S. foot traffic to drop nearly 10% in the days afterward, according to estimates by Gordon Haskett financial researchers. The fast-food giant [reported Tuesday](https://www.cnbc.com/2024/10/29/mcdonalds-mcd-earnings-q3-2024.html) that it had reversed its recent U.S. sales drop, posting a 0.3% uptick in the third quarter. Foot traffic was still down slightly, but the company said its summer of discounts was paying off. But by early this year, [photos of eye-watering menu prices](https://x.com/sam_learner/status/1681367351143301129) at some McDonald’s locations — including an $18 Big Mac combo at a Connecticut rest stop from July 2023 — went viral, bringing diners’ long-simmering frustrations to a boiling point that the company couldn’t ignore. On an earnings call in April, Kempczinski acknowledged that foot traffic had fallen. “We will stay laser-focused on providing an unparalleled experience with simple, everyday value and affordability that our consumers can count on as they continue to be mindful about their spending,” CEO Chris Kempczinski [said in a statement](https://www.prnewswire.com/news-releases/mcdonalds-reports-third-quarter-2024-results-302289216.html?Fds-Load-Behavior=force-external) alongside the earnings report.'}, {'index': 3, 'tags': ['food_&_dining', 'news_&_social_concern'], 'content': '![mcdonalds drive-thru economy fast food](https://media-cldnry.s-nbcnews.com/image/upload/t_fit-760w,f_auto,q_auto:best/rockcms/2024-10/241024-los-angeles-mcdonalds-drive-thru-ac-1059p-cfc311.jpg)McDonald’s has had some success leaning into discounts this year.

Going forward, McDonald’s would be “laser-focused” on affordability.  “McDonald’s has also done a good job of embedding the brand in popular culture to enhance its relevance and meaning around fun and family.
