Deep Dive: Scraping Airbnb Listings with Firecrawl

Now, let's dig into a more complex example: using Firecrawl to scrape Airbnb listings. This use case is particularly interesting because it involves dealing with dynamically loaded content, pagination, and extracting specific structured data.

Here's a step-by-step breakdown of how we can use Firecrawl to scrape Airbnb listings for San Francisco:

import FirecrawlApp from '@mendable/firecrawl-js'
import 'dotenv/config'
import { z } from 'zod'

async function scrapeAirbnb() {
  // Initialize the FirecrawlApp with your API key
  const app = new FirecrawlApp({ apiKey: process.env.FIRECRAWL_API_KEY })

  // Define the URL to crawl
  const listingsUrl = 'https://www.airbnb.com/s/San-Francisco--CA--United-States/homes'
  const baseUrl = 'https://www.airbnb.com'

  // Step 1: Extract pagination links
  const paginationSchema = z.object({
    page_links: z.array(
      z.object({
        link: z.string(),
      })
    ).describe('Pagination links in the bottom of the page.'),
  })

  const paginationParams = {
    pageOptions: { onlyMainContent: false },
    extractorOptions: { extractionSchema: paginationSchema },
    timeout: 50000, // Increased timeout for potentially slow-loading pages
  }

  const linksData = await app.scrapeUrl(listingsUrl, paginationParams)
  let paginationLinks = linksData.data['llm_extraction'].page_links.map(
    (link) => baseUrl + link.link
  )

  // Fallback if pagination links aren't found
  if (paginationLinks.length === 0) {
    paginationLinks = [listingsUrl]
  }

  // Step 2: Define schema for listing extraction
  const listingSchema = z.object({
    listings: z.array(
      z.object({
        title: z.string(),
        price_per_night: z.number(),
        location: z.string(),
        rating: z.number().optional(),
        reviews: z.number().optional(),
      })
    ).describe('Airbnb listings in San Francisco'),
  })

  const listingParams = {
    pageOptions: { onlyMainContent: false },
    extractorOptions: { extractionSchema: listingSchema },
  }

  // Step 3: Scrape listings from all pagination links
  const scrapeListings = async (url) => {
    const result = await app.scrapeUrl(url, listingParams)
    return result.data['llm_extraction'].listings
  }

  const listingsPromises = paginationLinks.map((link) => scrapeListings(link))
  const listingsResults = await Promise.all(listingsPromises)

  // Flatten the results
  const allListings = listingsResults.flat()

  return allListings
}

// Run the scraper
scrapeAirbnb().then((listings) => {
  console.log(`Scraped ${listings.length} Airbnb listings`)
  console.log(listings[0]) // Example of the first listing
}).catch((error) => {
  console.error('An error occurred:', error.message)
})

‍

Let's break down what this code does:

1. Initialization: We set up the FirecrawlApp with our API key.
2. Pagination Handling: Instead of hardcoding page numbers, we first scrape the pagination links. This makes our scraper more robust to changes in Airbnb's layout.
3. Schema Definition: We use Zod to define the structure of the data we want to extract. This tells Firecrawl exactly what information to pull from each listing.
4. Parallel Scraping: We scrape all pagination links concurrently, which significantly speeds up the process.
5. Error Handling: We incorporate error handling to make our scraper more resilient.

This example showcases several key strengths of Firecrawl:

• Flexibility: It can handle complex, multi-step scraping processes.
• Structured Data Extraction: The use of schemas ensures we get precisely the data we need.
• Performance: Parallel processing of multiple pages improves efficiency.
• Robustness: Error handling and fallbacks make the scraper more reliable.

By using Firecrawl for this task, we've eliminated the need to deal with browser automation, AJAX requests, and complex CSS selectors. Instead, we can focus on defining what data we want and how to process it, making our scraping tasks significantly more manageable and maintainable.

Current Limitations and Challenges

While Firecrawl offers powerful capabilities for web scraping and data extraction, it's important to acknowledge some current limitations:

1. Rate Limiting and IP Blocks: High-volume scraping can trigger rate limits or IP blocks from target websites, potentially interrupting data collection.
2. Geo-Restricted Content: Some websites serve different content based on geographic location, which can be challenging to access from a single point of origin.
3. CAPTCHA and Anti-Bot Measures: Sophisticated websites may employ CAPTCHA or other anti-bot measures that can hinder automated scraping.
4. Scalability Concerns: For very large-scale scraping operations, managing the load on a single IP address can be problematic.
5. Detection Avoidance: Some websites are becoming increasingly adept at detecting and blocking scraping activities, even when done at modest scales.

import { z } from 'zod'

async function scrapeAirbnbWithProxy() {
  const app = new FirecrawlApp({ apiKey: process.env.FIRECRAWL_API_KEY })

  // Stat Proxies configuration
  const proxyConfig = {
    'http': 'http://stat_user:super_secret_passowrd@proxy.statproxies.com:3128',
  }
  // Step 1: Extract pagination links
  const paginationSchema = z.object({
    page_links: z.array(
      z.object({
        link: z.string(),
      })
    ).describe('Pagination links in the bottom of the page.'),
  })

  const paginationParams = {
    pageOptions: { onlyMainContent: false },
    extractorOptions: { extractionSchema: paginationSchema },
    timeout: 50000,
    proxyConfig: proxyConfig  // Use Stat Proxies for pagination
  }

  const linksData = await app.scrapeUrl(listingsUrl, paginationParams)
  let paginationLinks = linksData.data['llm_extraction'].page_links.map(
    (link) => baseUrl + link.link
  )

  // Fallback if pagination links aren't found
  if (paginationLinks.length === 0) {
    paginationLinks = [listingsUrl]
  }

  // Step 2: Define schema for listing extraction
  const listingSchema = z.object({
    listings: z.array(
      z.object({
        title: z.string(),
        price_per_night: z.number(),
        location: z.string(),
        rating: z.number().optional(),
        reviews: z.number().optional(),
      })
    ).describe('Airbnb listings in San Francisco'),
  })

  const listingParams = {
    pageOptions: { onlyMainContent: false },
    extractorOptions: { extractionSchema: listingSchema },
    proxyConfig: proxyConfig  // Use Stat Proxies for listing extraction
  }

  // Step 3: Scrape listings from all pagination links
  const scrapeListings = async (url) => {
    const result = await app.scrapeUrl(url, listingParams)
    return result.data['llm_extraction'].listings
  }

  const listingsPromises = paginationLinks.map((link) => scrapeListings(link))
  const listingsResults = await Promise.all(listingsPromises)

  // Flatten the results
  const allListings = listingsResults.flat()

  return allListings
}

// Run the scraper
scrapeAirbnbWithProxy().then((listings) => {
  console.log(`Successfully scraped ${listings.length} Airbnb listings using Stat Proxies!`)
  console.log(listings[0]) // Example of the first listing
}).catch((error) => {
  console.error('An error occurred:', error.message)
})

By adding the proxyConfig to our Firecrawl parameters, we've now supercharged our scraping capabilities. This integration allows us to leverage Stat Proxies' extensive network of ethical residential IPs, ensuring higher success rates, better scalability, and improved anonymity in our web scraping operations.
