# @lobechat/web-crawler
LobeChat's built-in web crawling module for intelligent extraction of web content and conversion to Markdown format.
## 📝 Introduction
`@lobechat/web-crawler` is a core component of LobeChat responsible for intelligent web content crawling and processing. It extracts valuable content from various webpages, filters out distracting elements, and generates structured Markdown text.
## 🛠️ Core Features
- **Intelligent Content Extraction**: Identifies main content based on Mozilla Readability algorithm
- **Multi-level Crawling Strategy**: Supports multiple crawling implementations including basic crawling, Jina, and Browserless rendering
- **Custom URL Rules**: Handles specific website crawling logic through a flexible rule system
## 🤝 Contribution
Web structures are diverse and complex. We welcome community contributions for specific website crawling rules. You can participate in improvements through:
### How to Contribute URL Rules
1. Add new rules to the [urlRules.ts](https://github.com/lobehub/lobe-chat/blob/main/packages/web-crawler/src/urlRules.ts) file
2. Rule example:
```typescript
// Example: handling specific websites
const url = [
// ... other URL matching rules
{
// URL matching pattern, supports regex
urlPattern: 'https://example.com/articles/(.*)',
// Optional: URL transformation, redirects to an easier-to-crawl version
urlTransform: 'https://example.com/print/$1',
// Optional: specify crawling implementation, supports 'naive', 'jina', and 'browserless'
impls: ['naive', 'jina', 'browserless'],
// Optional: content filtering configuration
filterOptions: {
// Whether to enable Readability algorithm for filtering distracting elements
enableReadability: true,
// Whether to convert to plain text
pureText: false,
},
},
];
```
### Rule Submission Process
1. Fork the [LobeChat repository](https://github.com/lobehub/lobe-chat)
2. Add or modify URL rules
3. Submit a Pull Request describing:
