Deno Deploy
Use Firecrawl with Deno Deploy to search, scrape, and interact with web data at the edge.
Prerequisites
- Deno 1.40+ or Deno 2
- A Firecrawl API key — get one free
Setup
Create main.ts:
import Firecrawl from "npm:firecrawl";
const firecrawl = new Firecrawl({
apiKey: Deno.env.get("FIRECRAWL_API_KEY"),
});Search the web
Add a /search route that searches the web and returns results with full page content.
Deno.serve(async (req) => {
const url = new URL(req.url);
if (req.method === "POST" && url.pathname === "/search") {
const { query } = await req.json();
const results = await firecrawl.search(query, { limit: 5 });
return Response.json(results);
}
return new Response("Not found", { status: 404 });
});Scrape a page
Add a /scrape route to extract clean markdown from any URL.
if (req.method === "POST" && url.pathname === "/scrape") {
const { url: targetUrl } = await req.json();
const result = await firecrawl.scrape(targetUrl);
return Response.json(result);
}Interact with a page
Add an /interact route to control a live browser session — click buttons, fill forms, and extract dynamic content.
if (req.method === "POST" && url.pathname === "/interact") {
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 Response.json({ output: response.output });
