    }
  ]
}

Beginner-Friendly n8n Web Scraping Tutorials

Tutorial 1: Simple Product Scraping Workflow

Objective: Scrape product information from an e-commerce site

Steps: 1. Add an HTTP Request node to fetch the page 2. Connect an HTML Extract node with CSS selectors 3. Use a Set node to clean and format data 4. Store results in Google Sheets or Airtable

// n8n Code Node example for data cleaning
const items = $input.all();

return items.map(item => {
  return {
    json: {
      title: item.json.title.trim(),
      price: parseFloat(item.json.price.replace('$', '')),
      timestamp: new Date().toISOString()
    }
  };
});

Tutorial 2: Scheduled News Scraping

Set up a cron trigger to automatically scrape news headlines:

Workflow Structure:
1. Cron Node (daily at 9 AM)
2. HTTP Request (fetch news page)
3. HTML Extract (headlines and links)
4. Filter Node (remove duplicates)
5. Send email notification with results

Intermediate n8n Web Scraping Techniques

Working with Pagination

Many websites spread content across multiple pages. Here's how to handle pagination in n8n:

// n8n Code Node for pagination handling
const baseUrl = 'https://example.com/products';
const maxPages = 5;
const results = [];

for (let page = 1; page <= maxPages; page++) {
  const url = `${baseUrl}?page=${page}`;

  // Make HTTP request (you'll use HTTP Request node in n8n)
  // Extract data (use HTML Extract node)
  // This is pseudocode - actual implementation uses n8n nodes
}

return results.map(item => ({ json: item }));

Using Python in n8n for Advanced Scraping

While n8n primarily uses JavaScript, you can execute Python scripts for more complex scraping:

# Python code in n8n Execute Command node
import requests
from bs4 import BeautifulSoup
import json

url = sys.argv[1]
response = requests.get(url)
soup = BeautifulSoup(response.content, 'html.parser')

data = []
for item in soup.select('.product-item'):
    data.append({
        'title': item.select_one('.title').text,
        'price': item.select_one('.price').text,
        'rating': item.select_one('.rating')['data-rating']
    })

print(json.dumps(data))

Tutorial 3: Browser Automation with Puppeteer

For JavaScript-heavy websites, integrate Puppeteer through n8n's Code node:

// n8n Code Node with Puppeteer
const puppeteer = require('puppeteer');

async function scrapeDynamicContent() {
  const browser = await puppeteer.launch({ headless: true });
  const page = await browser.newPage();

  await page.goto('https://example.com/spa-app');

  // Wait for dynamic content to load
  await page.waitForSelector('.dynamic-content');

  const data = await page.evaluate(() => {
    const items = [];
    document.querySelectorAll('.item').forEach(el => {
      items.push({
        title: el.querySelector('.title').innerText,
        content: el.querySelector('.content').innerText
      });
    });
    return items;
  });

  await browser.close();
  return data;
}

const results = await scrapeDynamicContent();
return results.map(item => ({ json: item }));

This approach is particularly useful when you need to handle AJAX requests or interact with dynamic single-page applications.

Tutorial 4: API-Based Web Scraping

For reliable, scalable scraping, integrate a dedicated web scraping API:

// n8n HTTP Request node configuration for WebScraping.AI
{
  "method": "GET",
  "url": "https://api.webscraping.ai/html",
  "qs": {
    "api_key": "{{$env.WEBSCRAPING_API_KEY}}",
    "url": "https://example.com/products",
    "js": true,
    "proxy": "datacenter"
  }
}

Benefits of API-based scraping in n8n: - No need to manage browser instances - Built-in proxy rotation and CAPTCHA handling - Consistent response times - Easy error handling and retry logic

Tutorial 5: Multi-Step Authentication Workflows

Scraping authenticated content requires session management:

// n8n workflow: Login → Scrape → Logout
// Step 1: Login request
{
  "name": "Login",
  "type": "httpRequest",
  "parameters": {
    "url": "https://example.com/login",
    "method": "POST",
    "bodyParameters": {
      "username": "{{$env.USERNAME}}",
      "password": "{{$env.PASSWORD}}"
    },
    "options": {
      "followRedirect": true,
      "returnFullResponse": true
    }
  }
}

// Step 2: Extract session cookie
// Step 3: Use cookie in subsequent requests
// Step 4: Scrape protected content

For more complex authentication scenarios, you can learn how to handle authentication in Puppeteer and apply similar concepts in n8n.

Best Practices for n8n Web Scraping

Error Handling and Retry Logic

// Implement retry logic in n8n Code node
async function fetchWithRetry(url, maxRetries = 3) {
  for (let i = 0; i < maxRetries; i++) {
    try {
      const response = await fetch(url);
      if (response.ok) {
        return await response.text();
      }
    } catch (error) {
      if (i === maxRetries - 1) throw error;
      await new Promise(resolve => setTimeout(resolve, 1000 * (i + 1)));
    }
  }
}

const html = await fetchWithRetry($json.url);
return [{ json: { html } }];

Rate Limiting and Politeness

// Add delays between requests
const delay = ms => new Promise(resolve => setTimeout(resolve, ms));

const items = $input.all();
const results = [];

for (const item of items) {
  // Process item
  results.push(processedItem);

  // Wait 2 seconds between requests
  await delay(2000);
}

return results.map(r => ({ json: r }));

Monitoring and Logging

Set up error notifications and logging:

Workflow Monitoring:
1. Add Error Trigger node
2. Connect to Slack/Email notification
3. Log errors to database
4. Set up workflow execution history review

Common Challenges and Solutions

Challenge 1: Dynamic Content Loading

Solution: Use browser automation or wait for specific selectors to load before extracting data. Understanding how to handle browser sessions is crucial for maintaining state across requests.

Challenge 2: Anti-Scraping Measures

Solution: - Rotate user agents - Use proxy servers - Implement random delays - Respect robots.txt - Consider using a dedicated scraping API

Challenge 3: Data Quality and Consistency

Solution: Implement data validation and cleaning:

// n8n data validation example
function validateProductData(item) {
  const required = ['title', 'price', 'url'];
  const valid = required.every(field => item[field]);

  if (valid) {
    return {
      ...item,
      price: parseFloat(item.price.replace(/[^0-9.]/g, '')),
      scrapedAt: new Date().toISOString()
    };
  }
  return null;
}

const items = $input.all();
const validItems = items
  .map(item => validateProductData(item.json))
  .filter(item => item !== null);

return validItems.map(item => ({ json: item }));
