​
Prerequisites

  • Node.js 18+, Bun, or Deno
  • A Firecrawl API key — get one free

​
Setup

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

​
Search the web

import { Hono } from "hono";
import Firecrawl from "@mendable/firecrawl-js";

const app = new Hono();
const firecrawl = new Firecrawl({ apiKey: process.env.FIRECRAWL_API_KEY });

app.post("/search", async (c) => {
  const { query } = await c.req.json();
  const results = await firecrawl.search(query, { limit: 5 });
  return c.json(results);
});

export default app;

​
Scrape a page

app.post("/scrape", async (c) => {
  const { url } = await c.req.json();
  const result = await firecrawl.scrape(url);
  return c.json(result);
});

​
Interact with a page

Use interact to control a live browser session — click buttons, fill forms, and extract dynamic content. 
app.post("/interact", async (c) => {
  const { url } = await c.req.json();

  const result = await firecrawl.scrape(url, { 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 c.json({ output: response.output });
});

​
Deploy anywhere

Hono runs on multiple runtimes. For Cloudflare Workers, pass the API key from the environment binding: 
import { Hono } from "hono";
import Firecrawl from "@mendable/firecrawl-js";

type Bindings = { FIRECRAWL_API_KEY: string };
const app = new Hono<{ Bindings: Bindings }>();

app.post("/search", async (c) => {
  const firecrawl = new Firecrawl({ apiKey: c.env.FIRECRAWL_API_KEY });
  const { query } = await c.req.json();
  const results = await firecrawl.search(query, { limit: 5 });
  return c.json(results);
});

export default app;
