# Recent Changes - Full Content Storage

## ✅ What Changed

### 1. Removed Content Length Limit
**Before:**
```python
'content': content_text[:10000]  # Limited to 10k chars
```

**After:**
```python
'content': content_text  # Full content, no limit
```

### 2. Simplified Database Schema
**Before:**
```javascript
{
  summary: String,      // Short summary
  full_content: String  // Limited content
}
```

**After:**
```javascript
{
  content: String  // Full article content, no limit
}
```

### 3. Enhanced API Response
**Before:**
```javascript
{
  title: "...",
  link: "...",
  summary: "..."
}
```

**After:**
```javascript
{
  title: "...",
  author: "...",        // NEW!
  link: "...",
  preview: "...",       // First 200 chars
  word_count: 1250,     // NEW!
  has_full_content: true // NEW!
}
```

## 📊 Database Structure

### Articles Collection
```javascript
{
  _id: ObjectId,
  title: String,           // Article title
  author: String,          // Article author (extracted)
  link: String,            // Article URL (unique)
  content: String,         // FULL article content (no limit)
  word_count: Number,      // Word count
  source: String,          // RSS feed name
  published_at: String,    // Publication date
  crawled_at: DateTime,    // When crawled
  created_at: DateTime     // When added
}
```

## 🆕 New API Endpoint

### GET /api/news/<article_url>
Get full article content by URL.

**Example:**
```bash
# URL encode the article URL
curl "http://localhost:5001/api/news/https%3A%2F%2Fexample.com%2Farticle"
```

**Response:**
```json
{
  "title": "New U-Bahn Line Opens in Munich",
  "author": "Max Mustermann",
  "link": "https://example.com/article",
  "content": "The full article text here... (complete, no truncation)",
  "word_count": 1250,
  "source": "Süddeutsche Zeitung München",
  "published_at": "2024-11-10T10:00:00Z",
  "crawled_at": "2024-11-10T16:30:00Z",
  "created_at": "2024-11-10T16:00:00Z"
}
```

## 📈 Enhanced Stats

### GET /api/stats
Now includes crawled article count:

```json
{
  "subscribers": 150,
  "articles": 500,
  "crawled_articles": 350  // NEW!
}
```

## 🎯 Benefits

1. **Complete Content** - No truncation, full articles stored
2. **Better for AI** - Full context for summarization/analysis
3. **Cleaner Schema** - Single `content` field instead of `summary` + `full_content`
4. **More Metadata** - Author, word count, crawl timestamp
5. **Better API** - Preview in list, full content on demand

## 🔄 Migration

If you have existing articles with `full_content` field, they will continue to work. New articles will use the `content` field.

To migrate old articles:
```javascript
// MongoDB shell
db.articles.updateMany(
  { full_content: { $exists: true } },
  [
    {
      $set: {
        content: "$full_content"
      }
    },
    {
      $unset: ["full_content", "summary"]
    }
  ]
)
```

## 🚀 Usage

### Crawl Articles
```bash
cd news_crawler
python crawler_service.py 10
```

### Get Article List (with previews)
```bash
curl http://localhost:5001/api/news
```

### Get Full Article Content
```bash
# Get the article URL from the list, then:
curl "http://localhost:5001/api/news/<encoded_url>"
```

### Check Stats
```bash
curl http://localhost:5001/api/stats
```

## 📝 Example Workflow

1. **Add RSS Feed**
```bash
curl -X POST http://localhost:5001/api/rss-feeds \
  -H "Content-Type: application/json" \
  -d '{"name": "News Source", "url": "https://example.com/rss"}'
```

2. **Crawl Articles**
```bash
cd news_crawler
python crawler_service.py 10
```

3. **View Articles**
```bash

```

4. **Get Full Content**
```bash
# Copy article link from above, URL encode it
