Fazer uma busca na web

Edite 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" },
  });
});

​

Faça scraping de uma página

Edite 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" },
  });
});

​

Interaja com uma página

Edite 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" },
  });
});
