​
Prerequisites

  • Astro project with SSR enabled (output: "server" or "hybrid")
  • A Firecrawl API key — get one free

​
Install the SDK

npm install @mendable/firecrawl-js
Add your API key to .env: 
FIRECRAWL_API_KEY=fc-YOUR-API-KEY

​
Search the web

Create src/pages/api/search.ts: 
import type { APIRoute } from "astro";
import Firecrawl from "@mendable/firecrawl-js";

const firecrawl = new Firecrawl({
  apiKey: import.meta.env.FIRECRAWL_API_KEY,
});

export const POST: APIRoute = async ({ request }) => {
  const { query } = await request.json();
  const results = await firecrawl.search(query, { limit: 5 });
  return new Response(JSON.stringify(results), {
    headers: { "Content-Type": "application/json" },
  });
};
Or search at request time in a server-rendered page (src/pages/search.astro): 
---
import Firecrawl from "@mendable/firecrawl-js";

const firecrawl = new Firecrawl({
  apiKey: import.meta.env.FIRECRAWL_API_KEY,
});

const query = Astro.url.searchParams.get("q");
let results = [];

if (query) {
  const searchData = await firecrawl.search(query, { limit: 5 });
  results = searchData.web || [];
}
---

<html>
  <body>
    <h1>Search Results</h1>
    {results.length > 0 ? (
      <ul>
        {results.map((r) => (
          <li><a href={r.url}>{r.title}</a></li>
        ))}
      </ul>
    ) : (
      <p>Pass ?q= to search the web</p>
    )}
  </body>
</html>

​
Scrape a page

Create src/pages/api/scrape.ts: 
import type { APIRoute } from "astro";
import Firecrawl from "@mendable/firecrawl-js";

const firecrawl = new Firecrawl({
  apiKey: import.meta.env.FIRECRAWL_API_KEY,
});

export const POST: APIRoute = async ({ request }) => {
  const { url } = await request.json();
  const result = await firecrawl.scrape(url);
  return new Response(JSON.stringify(result), {
    headers: { "Content-Type": "application/json" },
  });
};
Or scrape at request time in a server-rendered page (src/pages/scrape.astro): 
---
import Firecrawl from "@mendable/firecrawl-js";

const firecrawl = new Firecrawl({
  apiKey: import.meta.env.FIRECRAWL_API_KEY,
});

const target = Astro.url.searchParams.get("url");
let markdown = null;

if (target) {
  const result = await firecrawl.scrape(target);
  markdown = result.markdown;
}
---

<html>
  <body>
    <h1>Scraped Content</h1>
    {markdown ? <pre>{markdown}</pre> : <p>Pass ?url= to scrape a page</p>}
  </body>
</html>

​
Interact with a page

Create src/pages/api/interact.ts: 
import type { APIRoute } from "astro";
import Firecrawl from "@mendable/firecrawl-js";

const firecrawl = new Firecrawl({
  apiKey: import.meta.env.FIRECRAWL_API_KEY,
});

export const POST: APIRoute = async () => {
  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 new Response(JSON.stringify({ output: response.output }), {
    headers: { "Content-Type": "application/json" },
  });
};
