# AWS Lambda

> Use Firecrawl with AWS Lambda to search, scrape, and interact with web data in serverless functions.

## Prerequisites

* AWS account with Lambda access
* A Firecrawl API key — [get one free](https://www.firecrawl.dev/app/api-keys)

## Setup

```bash theme={null}
mkdir firecrawl-lambda && cd firecrawl-lambda
npm init -y
npm install @mendable/firecrawl-js
```

## Search the web

Create `index.mjs` with a search handler:

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

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

export async function handler(event) {
  const body = JSON.parse(event.body || "{}");

  if (body.action === "search") {
    const results = await firecrawl.search(body.query, { limit: 5 });
    return {
      statusCode: 200,
      body: JSON.stringify(results),
    };
  }

  return { statusCode: 400, body: JSON.stringify({ error: "Unknown action" }) };
}
```

## Scrape a page

Add a `scrape` action to the same handler:

```javascript theme={null}
if (body.action === "scrape") {
  const result = await firecrawl.scrape(body.url);
  return {
    statusCode: 200,
    body: JSON.stringify(result),
  };
}
```

## Interact with a page

Add an `interact` action to control a live browser session — click buttons, fill forms, and extract dynamic content:

```javascript theme={null}
if (body.action === "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 {
    statusCode: 200,
    body: JSON.stringify({ output: response.output }),
  };
}
```

## Deploy

Package and deploy with the AWS CLI:

```bash theme={null}
zip -r function.zip index.mjs node_modules/

aws lambda create-function \
  --function-name firecrawl-scraper \
  --runtime nodejs20.x \
  --handler index.handler \
  --zip-file fileb://function.zip \
  --role arn:aws:iam::YOUR_ACCOUNT:role/lambda-role \
  --environment Variables="{FIRECRAWL_API_KEY=fc-YOUR-API-KEY}" \
  --timeout 60
```

<Note>
  Set the Lambda timeout to at least 30 seconds. Scraping dynamic pages and interact sessions can take longer than the default 3-second timeout.
