# Scraping Wikipedia

> Extract articles, infoboxes, and build knowledge graphs from Wikipedia

Learn how to effectively scrape Wikipedia for research, knowledge extraction, and building AI applications.

## Setup

```bash theme={null}
npm install @mendable/firecrawl-js zod
```

## Use Cases

* Research automation and fact-checking
* Building knowledge graphs
* Multi-language content extraction
* Educational content aggregation
* Entity information extraction

## Scrape with JSON Mode

Extract structured data from Wikipedia articles using Zod schemas.

```typescript theme={null}
import FirecrawlApp from '@mendable/firecrawl-js';
import { z } from 'zod';

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

const result = await firecrawl.scrape('https://en.wikipedia.org/wiki/JavaScript', {
    formats: [{
        type: 'json',
        schema: z.object({
            name: z.string(),
            creator: z.string(),
            firstAppeared: z.string(),
            typingDiscipline: z.string(),
            website: z.string()
        })
    }]
});

console.log(result.json);
```

## Search

Find articles on Wikipedia.

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

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

const searchResult = await firecrawl.search('quantum computing site:en.wikipedia.org', {
    limit: 10,
    sources: [{ type: 'web' }], // { type: 'news' }, { type: 'images' }
    scrapeOptions: {
        formats: ['markdown']
    }
});

console.log(searchResult);
```

## Scrape

Scrape a single Wikipedia article.

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

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

const result = await firecrawl.scrape('https://en.wikipedia.org/wiki/Artificial_intelligence', {
    formats: ['markdown'], // i.e. html, links, etc.
    onlyMainContent: true
});

console.log(result);
```

## Map

Discover all available URLs in a Wikipedia portal or category. Note: Map returns URLs only, without content.

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

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

const mapResult = await firecrawl.map('https://en.wikipedia.org/wiki/Portal:Computer_science');

console.log(mapResult.links);
// Returns array of URLs without content
```

## Crawl

Crawl multiple pages from Wikipedia documentation or categories.

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

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

const crawlResult = await firecrawl.crawl('https://en.wikipedia.org/wiki/Portal:Artificial_intelligence', {
    limit: 10,
    scrapeOptions: {
        formats: ['markdown']
    }
});

console.log(crawlResult.data);
```

## Batch Scrape

Scrape multiple Wikipedia URLs simultaneously.

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

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

// Wait for completion
const job = await firecrawl.batchScrape([
    'https://en.wikipedia.org/wiki/Machine_learning',
    'https://en.wikipedia.org/wiki/Artificial_intelligence',
    'https://en.wikipedia.org/wiki/Deep_learning'],
    {
        options: {
            formats: ['markdown']
        },
        pollInterval: 2,
        timeout: 120
    }
);


console.log(job.status, job.completed, job.total);

console.log(job);
```
