# Cloudflare Workers

> Use Firecrawl with Cloudflare Workers to search, scrape, and interact with web data at the edge.

## Prerequisites

* Wrangler CLI (`npm install -g wrangler`)
* A Firecrawl API key — [get one free](https://www.firecrawl.dev/app/api-keys)

## Setup

```bash theme={null}
npm create cloudflare@latest my-scraper
cd my-scraper
npm install @mendable/firecrawl-js
```

Add your API key as a secret:

```bash theme={null}
wrangler secret put FIRECRAWL_API_KEY
```

## Search the web

Create a handler that searches the web and returns results with full page content.

Edit `src/index.ts`:

```typescript theme={null}
import Firecrawl from "@mendable/firecrawl-js";

export interface Env {
  FIRECRAWL_API_KEY: string;
}

export default {
  async fetch(request: Request, env: Env): Promise<Response> {
    const firecrawl = new Firecrawl({ apiKey: env.FIRECRAWL_API_KEY });
    const url = new URL(request.url);

    if (request.method === "POST" && url.pathname === "/search") {
      const { query } = (await request.json()) as { query: string };
      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.

```typescript theme={null}
if (request.method === "POST" && url.pathname === "/scrape") {
  const { url: targetUrl } = (await request.json()) as { url: string };
  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.

```typescript theme={null}
if (request.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",
  });

  await firecrawl.stopInteraction(scrapeId);
  return Response.json({ output: response.output });
}
```

## Deploy

```bash theme={null}
wrangler deploy
```

## Test it

```bash theme={null}
curl -X POST https://my-scraper.<your-subdomain>.workers.dev/search \
  -H "Content-Type: application/json" \
  -d '{"query": "firecrawl web scraping"}'
```
