# Gitbook loader

### Overview

The GitBook Loader Node allows you to extract content from GitBook documentation pages. It can either load a single page or recursively load all pages from a GitBook documentation site, making it ideal for creating knowledge bases from GitBook documentation.

Usage cost: 1 credit for unique page / 10 credits for whole documentation

### Configuration

#### Settings

1. **GitBook URL**
   * URL to the GitBook documentation
   * Can be a specific page URL or root URL when loading all paths
   * Required field
   * Supports variable interpolation
2. **Load Options**
   * Load All Paths: Toggle to recursively load all pages
     * When enabled: URL must be the GitBook root
     * When disabled: Loads only the specified page

#### Output Ports

1. `documents` (List\[Document]): List of Document objects containing:
   * Page content
   * Metadata (URL, title, etc.)
2. `documents_content` (List\[string]):
   * List of extracted text content
   * Content only, without metadata

### Best Practices

1. **URL Configuration**
   * Use root URL when loading all paths
   * Ensure URLs are accessible (public documentation)
   * Verify URL format before execution
2. **Content Loading**
   * Use single page loading for specific content
   * Consider load time for large documentation sites

### Common Issues

* Rate limiting from GitBook servers
* Memory limitations with large documentation sites
* Slow loading times for recursive fetching
* Malformed URLs causing loading failures
