Next.js
在 React 应用中结合 Next.js 使用 Firecrawl，抓取、搜索并与网页数据交互。
- Next.js 14+ 项目 (App Router)
- 一个 Firecrawl API 密钥 — 免费获取
npm install firecrawl将 API 密钥添加到 .env.local：
FIRECRAWL_API_KEY=fc-YOUR-API-KEY该 SDK 只能在服务端运行，因为它需要你的 API 密钥。
创建 app/api/search/route.ts：
import { NextResponse } from "next/server";
import { Firecrawl } from "firecrawl";
const firecrawl = new Firecrawl({ apiKey: process.env.FIRECRAWL_API_KEY });
export async function POST(request: Request) {
const { query } = await request.json();
const results = await firecrawl.search(query, { limit: 5 });
return NextResponse.json(results);
}创建 app/actions.ts，供客户端组件调用：
"use server";
import { Firecrawl } from "firecrawl";
const firecrawl = new Firecrawl({ apiKey: process.env.FIRECRAWL_API_KEY });
export async function searchWeb(query: string) {
const results = await firecrawl.search(query, { limit: 5 });
return (results.web || []).map((r) => ({ title: r.title, url: r.url }));
}创建 app/api/scrape/route.ts：
import { NextResponse } from "next/server";
import { Firecrawl } from "firecrawl";
const firecrawl = new Firecrawl({ apiKey: process.env.FIRECRAWL_API_KEY });
export async function POST(request: Request) {
const { url } = await request.json();
const result = await firecrawl.scrape(url);
return NextResponse.json(result);
}在 app/page.tsx 的服务器组件中直接获取数据：
import { Firecrawl } from "firecrawl";
const firecrawl = new Firecrawl({ apiKey: process.env.FIRECRAWL_API_KEY });
export default async function Page() {
const result = await firecrawl.scrape("https://example.com");
return (
<article>
<h1>Scraped Content</h1>
<pre>{result.markdown}</pre>
</article>
);
}使用 interact 控制实时浏览器会话，可点击按钮、填写表单并提取动态内容。
创建 app/api/interact/route.ts：
import { NextResponse } from "next/server";
import { Firecrawl } from "firecrawl";
const firecrawl = new Firecrawl({ apiKey: process.env.FIRECRAWL_API_KEY });
export async function POST(request: Request) {
const { url, prompts } = await request.json();
const result = await firecrawl.scrape(url, { formats: ['markdown'] });
const scrapeId = result.metadata?.scrapeId;
await firecrawl.interact(scrapeId, { prompt: 'Search for iPhone 16 Pro Max' });
const response = await firecrawl.interact(scrapeId, { prompt: 'Click on the first result and tell me the price' });
await firecrawl.stopInteraction(scrapeId);
return NextResponse.json({ output: response.output });
