# Firecrawl Migration Deep Dive ## Current State !`npm list puppeteer playwright cheerio 2>/dev/null | grep -E "puppeteer|playwright|cheerio" || echo 'No scraping libs found'` ## Overview Migrate from custom scraping (Puppeteer, Playwright, Cheerio) or competing APIs to Firecrawl. Firecrawl eliminates browser management, anti-bot handling, and JS rendering infrastructure. This skill shows equivalent code for common scraping patterns. ## Migration Comparison | Feature | Puppeteer/Playwright | Cheerio | Firecrawl | |---------|---------------------|---------|-----------| | JS rendering | Manual browser | No | Automatic | | Anti-bot bypass | DIY (stealth plugin) | No | Built-in | | Output format | Raw HTML | Parsed HTML | Markdown/JSON/HTML | | Infrastructure | Browser instances | None | API call | | Concurrent scraping | Manage browser pool | Simple | Managed by Firecrawl | | Cost model | Compute (CPU/RAM) | Free | Credits per page | ## Instructions ### Step 1: Replace Puppeteer Single-Page Scrape ```typescript // BEFORE: Puppeteer (20+ lines, browser management) import puppeteer from "puppeteer"; async function scrapePuppeteer(url: string) { const browser = await puppeteer.launch(); const page = await browser.newPage(); await page.goto(url, { waitUntil: "networkidle2" }); const html = await page.content(); const title = await page.title(); await browser.close(); return { html, title }; } // AFTER: Firecrawl (5 lines, no browser needed) import FirecrawlApp...
