# Firecrawl Hello World ## Overview Four minimal examples covering Firecrawl's core endpoints: **scrape** (single page), **crawl** (multi-page), **map** (URL discovery), and **extract** (LLM structured data). Each is a standalone snippet you can run immediately. ## Prerequisites - `@mendable/firecrawl-js` installed (`npm install @mendable/firecrawl-js`) - `FIRECRAWL_API_KEY` environment variable set ## Instructions ### Step 1: Single-Page Scrape ```typescript import FirecrawlApp from "@mendable/firecrawl-js"; const firecrawl = new FirecrawlApp({ apiKey: process.env.FIRECRAWL_API_KEY!, }); // Scrape one page — returns markdown, HTML, metadata, links const result = await firecrawl.scrapeUrl("https://docs.firecrawl.dev", { formats: ["markdown"], }); console.log("Title:", result.metadata?.title); console.log("Markdown:", result.markdown?.substring(0, 500)); ``` ### Step 2: Multi-Page Crawl ```typescript // Crawl a site recursively — follows links, respects robots.txt const crawlResult = await firecrawl.crawlUrl("https://docs.firecrawl.dev", { limit: 10, // max 10 pages (saves credits) scrapeOptions: { formats: ["markdown"], }, }); console.log(`Crawled ${crawlResult.data?.length} pages`); for (const page of crawlResult.data || []) { console.log(` ${page.metadata?.title} — ${page.metadata?.sourceURL}`); } ``` ### Step 3: Map a Site (URL Discovery) ```typescript // Discover all URLs on a site in ~2-3 seconds (uses sitemap + SERP) const mapResult = await f...
