## Prerequisites [#prerequisites]
* Node.js 18+
* A Firecrawl API key — [get one free](https://www.firecrawl.dev/app/api-keys)
## Install the SDK [#install-the-sdk]
```bash
npm install firecrawl
```
## Environment variable [#environment-variable]
Instead of passing `apiKey` directly, set the `FIRECRAWL_API_KEY` environment variable:
```bash
export FIRECRAWL_API_KEY=fc-YOUR-API-KEY
```
```javascript
const app = new Firecrawl();
```
## Search the web [#search-the-web]
```javascript
import { Firecrawl } from 'firecrawl';
const app = new Firecrawl({ apiKey: "fc-YOUR-API-KEY" });
const results = await app.search("firecrawl web scraping", { limit: 5 });
for (const result of results.web) {
console.log(result.title, result.url);
}
```
## Scrape a page [#scrape-a-page]
```javascript
const result = await app.scrape("https://example.com");
console.log(result.markdown);
```
```json
{
"markdown": "# Example Domain\n\nThis domain is for use in illustrative examples...",
"metadata": {
"title": "Example Domain",
"sourceURL": "https://example.com"
}
}
```
## Interact with a page [#interact-with-a-page]
Use interact to control a live browser session — click buttons, fill forms, and extract dynamic content.
```javascript
const result = await app.scrape('https://www.amazon.com', { formats: ['markdown'] });
const scrapeId = result.metadata?.scrapeId;
await app.interact(scrapeId, { prompt: 'Search for iPhone 16 Pro Max' });
const response = await app.interact(scrapeId, { prompt: 'Click on the first result and tell me the price' });
console.log(response.output);
await app.stopInteraction(scrapeId);
```
