# Architecture Redesign - Completed ✅

## What Changed

Your site has been successfully refactored to eliminate duplication and create a clean, maintainable structure.

### Before (Confusing):
```
home/index.md          ← Old, unused
content/home/index.md  ← New source
home/index.json        ← Generated
home/assets.pdf        ← Assets mixed in
```

### After (Clean):
```
content/home/index.md           ← SOURCE (edit this)
content/home/assets.pdf         ← Assets go here
public/home/index.json          ← GENERATED (auto-created)
```

## New File Structure

## How It Works Now

### The Flow
```
You edit:        content/german/index.md
                 (markdown file with content)
  ↓
You run:         ./rebuild.sh
  ↓
Which runs:      generate_json.php
  ↓
That reads:      content/german/index.md
  ↓
Converts to:     HTML via comrak
  ↓
Writes to:       public/german/index.json
  ↓
Browser loads:   index.php (fetches public/german/index.json)
  ↓
.htaccess serves: Assets from content/german/ transparently
  ↓
User sees:       Full page with images, PDFs, etc.
```

### Asset Serving (Transparent to User)

When markdown references: `![img](/german/gv.png)`

1. Browser requests: `GET /german/gv.png`
2. `.htaccess` rewrites to: `GET /content/german/gv.png`
3. File served from: `content/german/gv.png`
4. User sees: `/german/gv.png` (clean URL)

---

## Daily Workflow

### Edit Content
```bash
# Edit markdown in content/ folder
nano content/blog/my-new-post.md
nano content/german/index.md
```

### Add Assets
```bash
# Add images/PDFs to content/ folder
cp ~/Downloads/image.png content/german/
```

### Reference Assets in Markdown
```markdown
![German Books](/german/Mittelpunkt_neu_B2_Lehrbuch.pdf)
![QR Code](/german/gv.png)
```

Note: Reference path = `/section/filename`

### Regenerate
```bash
./rebuild.sh
```

### Refresh Browser
```
Ctrl+F5 (or Cmd+Shift+R on Mac)
```

Done! Changes appear immediately.

## What Was Done

### Phase 1: Setup ✓
- Created `/public/` directory for generated files
- Updated `generate_json.php` to output to `public/`
- Updated `index.php` to fetch from `public/`
- Updated `.htaccess` for asset serving

### Phase 2: Asset Migration ✓
- Copied German PDFs to `content/german/`
- Copied German images to `content/german/`
- Copied pictures to `content/pics/`
- Copied files to `content/files/cv/` and `content/files/x/`

### Phase 3: Cleanup ✓
- Deleted old duplicate directories (`home/`, `blog/`, etc.)
- Created `_OLD_BACKUP/` for safety
- Verified all files in correct location

### Phase 4: Testing ✓
- Verified JSON generation
- Verified asset references
- Verified markdown conversion
- All systems working

## Benefits of New Architecture

| Aspect | Before | After |
|--------|--------|-------|
| **Source location** | Scattered (content/ + home/ + blog/ + ...) | Single (`content/`) |
| **Assets location** | Mixed with JSON | With markdown (content/) |
| **Generated files** | Everywhere | Organized (public/) |
| **Clarity** | Confusing duplication | Clear, simple structure |
| **Maintenance** | Hard to track | Easy, obvious what to edit |
| **Scalability** | Limited | Grows naturally |

---

## Progressive Enhancement Ready

Your insight was perfect: "markdown → JSON → PHP, later enhance with JavaScript"

The new structure supports this perfectly:

**Phase 1 (Now):** Basic rendering
```
Markdown → JSON (innerHTML) → PHP renders
```

**Phase 2 (Optional):** Add metadata
```json
{
  "section": {
    "innerHTML": "...",
    "title": "German Course",
    "updated": "2026-02-12",
    "author": "jisifu"
  }
}
```

**Phase 3 (Optional):** Client-side enhancements
```javascript
const data = await fetch('/public/german/index.json').then(r => r.json());
// Now use data.section.title, .updated, etc. for interactive features
```

**Phase 4 (Optional):** Add structured data (SEO)
```json
{
  "section": { "innerHTML": "..." },
  "metadata": {
    "@type": "BlogPost",
    "title": "...",
    "datePublished": "..."
  }
}
```

Your architecture grows with you, no major rewrites needed.

## Important Notes

1. **Always edit in `/content/`** - This is your source of truth
2. **Don't edit `/public/`** - It's auto-generated, changes will be overwritten
3. **Keep backup** - `_OLD_BACKUP/` is available if you need it
4. **Assets stay in content/** - PDFs, images, etc. go in the same folder as the markdown

---

## If Something Goes Wrong

1. **JSON not updating?** - Run `./rebuild.sh` again
2. **Assets not showing?** - Check they're in `content/section/` folder
3. **Need to revert?** - Restore from `_OLD_BACKUP/`
4. **Clear browser cache** - Ctrl+F5 (hard refresh)

---

## Commands Reference

```bash
# Rebuild site
./rebuild.sh

# Start auto-watcher
nohup php watch.php > watch.log 2>&1 &

# Stop auto-watcher
pkill -f "php watch.php"

# View file structure
ls -la content/
ls -la public/

# Edit content
nano content/blog/post.md

# Delete old backup when confident
rm -rf _OLD_BACKUP/
```
