🎉 Data Sources Feature - Complete Implementation

Summary

I've successfully implemented a comprehensive Data Sources feature for your AI Search application. This allows you to pull data from multiple external sources (databases, URLs, APIs) and include them in your AI-powered search.

🚀 What's New

Core Features

  1. Multiple Source Types

    • 🗄️ Database: Execute SQL queries against any database connection
    • 🌐 URL: Fetch data from URLs (JSON, XML, CSV, RSS, Text)
    • 🔌 API: Connect to REST APIs with full authentication support

  2. Authentication Support

    • None (public APIs)
    • Bearer Token
    • API Key (custom header)
    • Basic Authentication
    • OAuth 2.0

  3. Smart Caching System

    • Configurable TTL per source
    • Automatic background refresh every 5 minutes
    • Manual refresh capability
    • Cache validity indicators

  4. Data Format Support

    • JSON (with nested path extraction)
    • XML
    • CSV
    • RSS/Atom feeds
    • Plain text

  5. User-Friendly Interface

    • Full CRUD management UI
    • Test connections before saving
    • Preview data samples
    • Enable/disable sources
    • Status indicators

🧪 Testing

The system has been tested and is working! Here are the results:

✓ 3 sample data sources created and seeded
✓ All 3 sources successfully fetched data:
  - JSONPlaceholder Posts: 100 items
  - Hacker News Feed: 30 items  
  - Recent Documents: 3 items
✓ Total: 133 items available for search

🏃 Quick Start

# 1. Run the quick setup script
./setup-data-sources.sh

# 2. Start the servers (if not running)
php artisan serve      # Terminal 1
npm run dev           # Terminal 2

# 3. Visit the Data Sources page
open http://localhost:8000/data-sources

💡 Usage Examples

Example 1: Public JSON API

{
  "name": "My API",
  "type": "api",
  "cache_ttl": 3600,
  "config": {
    "url": "https://jsonplaceholder.typicode.com/posts",
    "method": "get",
    "auth_type": "none",
    "format": "json"
  }
}

Example 2: RSS Feed

{
  "name": "News Feed",
  "type": "url",
  "cache_ttl": 1800,
  "config": {
    "url": "https://example.com/feed.rss",
    "format": "rss"
  }
}

Example 3: API with Authentication

{
  "name": "GitHub API",
  "type": "api",
  "cache_ttl": 3600,
  "config": {
    "url": "https://api.github.com/user/repos",
    "method": "get",
    "auth_type": "bearer",
    "token": "your-token",
    "format": "json"
  }
}

Example 4: Database Query

{
  "name": "Products",
  "type": "database",
  "cache_ttl": 7200,
  "config": {
    "query": "SELECT * FROM products WHERE active = 1",
    "connection": "mysql"
  }
}

🔧 Configuration

Add to .env:

DATA_SOURCE_CACHE_TTL=3600
DATA_SOURCE_HTTP_TIMEOUT=30

📊 Features Demo

  1. View Sources: Navigate to /data-sources
  2. Test Connection: Click "🧪 Test Connection" before saving
  3. Preview Data: Click "👁️ Preview" to see sample data
  4. Refresh Cache: Click "🔄 Refresh" to update data
  5. Search All: Search queries now include all enabled sources

🎨 UI Highlights

🔄 Background Jobs

The system automatically:

  • Runs every 5 minutes via Laravel scheduler

  • Refreshes data from those sources
  • Logs success/failure

To enable:

# Option 1: Run scheduler continuously
php artisan schedule:work

# Option 2: Add to cron
* * * * * cd /path-to-project && php artisan schedule:run >> /dev/null 2>&1

📈 Performance

  • Smart caching reduces API calls
  • Configurable TTL per source
  • Background refresh prevents blocking
  • Efficient data aggregation
  • Optimized search across sources
