前提条件

​
安装 SDK

npm install @mendable/firecrawl-js
将 API 密钥添加到 .env： 
FIRECRAWL_API_KEY=fc-YOUR-API-KEY

​
进行网页搜索

在 src/routes/search/+page.server.ts 中创建表单 action： 
import Firecrawl from "@mendable/firecrawl-js";
import { FIRECRAWL_API_KEY } from "$env/static/private";

const firecrawl = new Firecrawl({ apiKey: FIRECRAWL_API_KEY });

export const actions = {
  default: async ({ request }) => {
    const data = await request.formData();
    const query = data.get("query") as string;
    const results = await firecrawl.search(query, { limit: 5 });
    return { results: (results.web || []).map((r) => ({ title: r.title, url: r.url })) };
  },
};
在 src/routes/search/+page.svelte 中完成接入： 
<script>
  export let form;
</script>

<form method="POST">
  <input name="query" placeholder="进行网页搜索..." />
  <button>搜索</button>
</form>

{#if form?.results}
  {#each form.results as result}
    <div><a href={result.url}>{result.title}</a></div>
  {/each}
{/if}

​
抓取页面

在 src/routes/scrape/+page.server.ts 的 load 函数中获取数据： 
import Firecrawl from "@mendable/firecrawl-js";
import { FIRECRAWL_API_KEY } from "$env/static/private";

const firecrawl = new Firecrawl({ apiKey: FIRECRAWL_API_KEY });

export async function load({ url }) {
  const target = url.searchParams.get("url");
  if (!target) return { markdown: null };

  const result = await firecrawl.scrape(target);
  return { markdown: result.markdown };
}
在 src/routes/scrape/+page.svelte 中显示它： 
<script>
  export let data;
</script>

{#if data.markdown}
  <pre>{data.markdown}</pre>
{:else}
  <p>Pass ?url= to scrape a page</p>
{/if}

​
与页面交互

在 src/routes/api/interact/+server.ts 中创建一个服务端端点： 
import { json } from "@sveltejs/kit";
import Firecrawl from "@mendable/firecrawl-js";
import { FIRECRAWL_API_KEY } from "$env/static/private";

const firecrawl = new Firecrawl({ apiKey: FIRECRAWL_API_KEY });

export async function POST() {
  const result = await firecrawl.scrape("https://www.amazon.com", {
    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 json({ output: response.output });
}
