Crawl and convert any website into LLM-ready markdown. Built by [Mendable.ai](https://mendable.ai?ref=gfirecrawl) and the firecrawl community. Includes powerful scraping, crawling and data extraction capabilities.
_This repository is in its early development stages. We are still merging custom modules in the mono repo. It's not completely yet ready for full self-host deployment, but you can already run it locally._
[Firecrawl](https://firecrawl.dev?ref=github) is an API service that takes a URL, crawls it, and converts it into clean markdown or structured data. We crawl all accessible subpages and give you clean data for each. No sitemap required.
We provide an easy to use API with our hosted version. You can find the playground and documentation [here](https://firecrawl.dev/playground). You can also self host the backend if you'd like.

With LLM extraction, you can easily extract structured data from any URL. We support pydanti schemas to make it easier for you too. Here is how you to use it:
To install the Firecrawl Node SDK, you can use npm:
```bash
npm install @mendable/firecrawl-js
```
### Usage
1. Get an API key from [firecrawl.dev](https://firecrawl.dev)
2. Set the API key as an environment variable named `FIRECRAWL_API_KEY` or pass it as a parameter to the `FirecrawlApp` class.
### Scraping a URL
To scrape a single URL with error handling, use the `scrapeUrl` method. It takes the URL as a parameter and returns the scraped data as a dictionary.
```js
try {
const url = 'https://example.com';
const scrapedData = await app.scrapeUrl(url);
console.log(scrapedData);
} catch (error) {
console.error(
'Error occurred while scraping:',
error.message
);
}
```
### Crawling a Website
To crawl a website with error handling, use the `crawlUrl` method. It takes the starting URL and optional parameters as arguments. The `params` argument allows you to specify additional options for the crawl job, such as the maximum number of pages to crawl, allowed domains, and the output format.
```js
const crawlUrl = 'https://example.com';
const params = {
crawlerOptions: {
excludes: ['blog/'],
includes: [], // leave empty for all pages
limit: 1000,
},
pageOptions: {
onlyMainContent: true
}
};
const waitUntilDone = true;
const timeout = 5;
const crawlResult = await app.crawlUrl(
crawlUrl,
params,
waitUntilDone,
timeout
);
```
### Checking Crawl Status
To check the status of a crawl job with error handling, use the `checkCrawlStatus` method. It takes the job ID as a parameter and returns the current status of the crawl job.
With LLM extraction, you can easily extract structured data from any URL. We support zod schema to make it easier for you too. Here is how you to use it:
```js
import FirecrawlApp from "@mendable/firecrawl-js";
With the `search` method, you can search for a query in a search engine and get the top results along with the page content for each result. The method takes the query as a parameter and returns the search results.
```js
const query = 'what is mendable?';
const searchResults = await app.search(query, {
pageOptions: {
fetchPageContent: true // Fetch the page content for each search result
