Supabase Edge Functions

使用 Firecrawl 与 Supabase Edge Functions，在边缘搜索、抓取并与网页数据交互。

​

前提条件

• 已使用 CLI 初始化 (supabase init) 的 Supabase 项目
• Firecrawl API 密钥——免费获取一个

​

配置

supabase functions new firecrawl-search
supabase functions new firecrawl-scrape
supabase functions new firecrawl-interact

设置密钥：

supabase secrets set FIRECRAWL_API_KEY=fc-YOUR-API-KEY

​

进行网页搜索

编辑 supabase/functions/firecrawl-search/index.ts：

import Firecrawl from "npm:@mendable/firecrawl-js";

const firecrawl = new Firecrawl({
  apiKey: Deno.env.get("FIRECRAWL_API_KEY"),
});

Deno.serve(async (req) => {
  const { query } = await req.json();
  const results = await firecrawl.search(query, { limit: 5 });

  return new Response(JSON.stringify(results), {
    headers: { "Content-Type": "application/json" },
  });
});

​

抓取页面

编辑 supabase/functions/firecrawl-scrape/index.ts：

import Firecrawl from "npm:@mendable/firecrawl-js";

const firecrawl = new Firecrawl({
  apiKey: Deno.env.get("FIRECRAWL_API_KEY"),
});

Deno.serve(async (req) => {
  const { url } = await req.json();
  const result = await firecrawl.scrape(url);

  return new Response(JSON.stringify(result), {
    headers: { "Content-Type": "application/json" },
  });
});

​

与页面进行交互

编辑 supabase/functions/firecrawl-interact/index.ts：

import Firecrawl from "npm:@mendable/firecrawl-js";

const firecrawl = new Firecrawl({
  apiKey: Deno.env.get("FIRECRAWL_API_KEY"),
});

Deno.serve(async (_req) => {
  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",
  });
  console.log(response.output);

  await firecrawl.stopInteraction(scrapeId);

  return new Response(JSON.stringify({ output: response.output }), {
    headers: { "Content-Type": "application/json" },
  });
});

​

部署

supabase functions deploy firecrawl-search
supabase functions deploy firecrawl-scrape
supabase functions deploy firecrawl-interact

​

试一试

curl -X POST https://<project-ref>.supabase.co/functions/v1/firecrawl-search \
  -H "Authorization: Bearer <ANON_KEY>" \
  -H "Content-Type: application/json" \
  -d '{"query": "firecrawl web scraping"}'
