pip(aam taur par Python ke sath aata hai)- Ek terminal ya command prompt
Step-by-Step Installation:
- Crawl4AI Package Install Karein: Apne terminal ko kholein aur latest stable version install karne ke liye yeh command chalayen:
pip install -U crawl4aiYeh command Crawl4AI ka asynchronous version install karta hai, jo web crawling ke liye Playwright istemal karta hai. - Post-Installation Setup Chalayen: Yeh ek bohat aham step hai jo zaroori Playwright browser binaries (default mein Chromium) ko install karta hai. Yeh command execute karein:
crawl4ai-setupAgar aapko is step ke dauran koi masla aata hai, to aap browser dependencies ko manually is tarah install kar sakte hain:python -m playwright install --with-deps chromium - Apni Installation Verify Karein (Optional lekin Recommended): Yeh yakeeni banane ke liye ke sab kuch theek se setup ho gaya hai, aap diagnostic tool istemal kar sakte hain:
crawl4ai-doctorAap ek simple crawl script ke sath bhi jaldi se verify kar sakte hain:import asynciofrom crawl4ai import AsyncWebCrawlerasync def main(): async with AsyncWebCrawler() as crawler: result = await crawler.arun(url="https://www.example.com") print(result.markdown[:300]) # Show the first 300 characters of extracted textif __name__ == "__main__": asyncio.run(main())
Kaise Istemal Karein (Usage Examples)
Aayen, Crawl4AI ko apne data extraction ki zarooraton ke liye kaise istemal karein, iske kuch practical examples dekhte hain.
Example 1: Basic Single-Page Crawl aur Markdown Extraction
Crawl4AI ko istemal karne ka sabse asaan tareeqa yeh hai ke ek single page ko fetch kiya jaye aur uske content ko extract kiya jaye, jo aksar LLMs ke liye clean Markdown format mein hota hai.
import asynciofrom crawl4ai import AsyncWebCrawlerasync def basic_crawl(): print("\n--- Performing Basic Single-Page Crawl ---") async with AsyncWebCrawler() as crawler: url_to_crawl = "https://www.scrapingbee.com/blog/" result = await crawler.arun(url=url_to_crawl) if result.success: print(f"Crawled URL: {result.url}") print(f"Page Title: {result.metadata.title}") print("\n--- Extracted Markdown (first 500 chars) ---") print(result.markdown[:500]) print(f"\nTotal Markdown Word Count: {result.markdown_word_count}") else: print(f"Failed to crawl {url_to_crawl}: {result.error_message}")if __name__ == "__main__": asyncio.run(basic_crawl())Yeh script ek AsyncWebCrawler ko initialize karta hai, specified URL par navigate karta hai, aur page ka title aur uske Markdown content ke pehle 500 characters print karta hai.
Example 2: Structured Data ko CSS Selectors se Extract Karna
Mazeed khaas data extraction ke liye, Crawl4AI aapko CSS selectors ka istemal karte hue schema define karne ki ijazat deta hai taake structured information nikali ja sake, jo databases ko populate karne ya specialized AI models ko feed karne ke liye behtareen hai.
import asyncioimport jsonfrom crawl4ai import AsyncWebCrawler, CrawlerRunConfigfrom crawl4ai.extraction_strategy import JsonCssExtractionStrategyasync def structured_extraction(): print("\n--- Extracting Structured Data with CSS Selectors ---") async with AsyncWebCrawler() as crawler: # Define the schema using CSS selectors # This example assumes a blog post structure schema = { "title": "h1.entry-title", "author": "span.author-name", "date": "time.entry-date", "paragraphs": { "selector": "div.entry-content p", "type": "list" } } # For demonstration, we'll use a generic blog post URL # You would adapt this to your specific target website url_to_scrape = "https://blog.hubspot.com/marketing/blog-post-template" config = CrawlerRunConfig( extraction_strategy=JsonCssExtractionStrategy(schema=schema) ) result = await crawler.arun(url=url_to_scrape, config=config) if result.success and result.extracted_content: print(f"Crawled URL: {result.url}") print("\n--- Extracted Structured JSON ---") extracted_data = json.loads(result.extracted_content) print(json.dumps(extracted_data, indent=2)) else: print(f"Failed to extract structured data from {url_to_scrape}: {result.error_message}")if __name__ == "__main__": asyncio.run(structured_extraction())Yeh example dikhata hai ke CSS selectors ke sath JSON schema kaise define kiya jaye aur JsonCssExtractionStrategy ko webpage se khaas elements extract karne ke liye kaise istemal kiya jaye. Output clean, structured JSON hota hai.
Example 3: Kayi Pages ki Deep Crawling
Crawl4AI sirf single pages ke liye nahi hai; yeh deep crawls bhi kar sakta hai, links ko follow karte hue ek website mein navigate karta hai. Yeh comprehensive datasets banane ke liye bohat qeemti hai.
import asynciofrom crawl4ai import AsyncWebCrawler, CrawlerRunConfig, DeepCrawlConfigasync def deep_crawl_example(): print("\n--- Performing Deep Crawl ---") async with AsyncWebCrawler() as crawler: start_url = "https://docs.crawl4ai.com/" # Using Crawl4AI's documentation for a safe example deep_config = DeepCrawlConfig( start_url=start_url, max_depth=1, # Go one link deep from the start URL max_pages=5, # Limit to 5 pages for this example strategy="bfs" # Breadth-First Search ) # Ensure the deep_crawl method is correctly called # The arun_many method is suitable for handling multiple URLs from a deep crawl print(f"Starting deep crawl from: {start_url}") results = await crawler.arun_many(deep_crawl_config=deep_config) for i, result in enumerate(results): if result.success: print(f"\n--- Page {i+1}: {result.url} ---") print(f"Title: {result.metadata.title}") print(f"Word Count: {result.markdown_word_count}") # print(result.markdown[:200]) # Uncomment to see snippet of markdown else: print(f"\n--- Failed to crawl page: {result.url} ---") print(f"Error: {result.error_message}")if __name__ == "__main__": asyncio.run(deep_crawl_example())Yeh script Crawl4AI documentation se shuru hone wala deep crawl set karta hai, depth aur pages ki tadaad ko mehdood rakhta hai. Yeh links discover karne ke liye Breadth-First Search (BFS) strategy istemal karta hai.
