# Architecture Decision: Customer-SPA Placement

## The Question

Should `customer-spa` be:
- **Option A:** Built into WooNooW core plugin (alongside `admin-spa`)
- **Option B:** Separate WooNooW theme (standalone product)

---

## Option A: Customer-SPA in Core Plugin

### Structure:
```
woonoow/
├── admin-spa/          (Admin interface)

├── includes/
│   ├── Frontend/       (Customer frontend logic)

└── woonoow.php
```

## Technical Considerations

### Performance

Customer page load: 300KB (customer-spa)
Total plugin size: 8MB
```

**Option B (Theme):**
```
Admin page load: 200KB (admin-spa)

Plugin size: 4MB
Theme size: 4MB
```

**Winner:** Tie (same total load)

### Maintenance

**Option A:**
- Single codebase
- Single release
- Easier version control
- Less coordination

**Option B:**
- Two codebases
- Coordinated releases
- Version compatibility matrix
- More complexity

**Winner:** ✅ **Option A**

- Can use with any theme (shortcodes)
- Hybrid approach possible

**Option B:**
- Full theme control
- Can create variations
- Better for customization

**Winner:** ✅ **Option B**

---

## Hybrid Approach (Recommended)

### Best of Both Worlds:

**WooNooW Plugin (Core):**
```
woonoow/
├── admin-spa/              (Always active)
├── customer-spa/           (Optional, can be disabled)
├── includes/
│   ├── Admin/
│   └── Frontend/
│       ├── Shortcodes/     (For any theme)
│       └── SPA/            (Full SPA mode)
└── woonoow.php
```

**Settings:**
```php
// WooNooW > Settings > Developer
Frontend Mode:
○ Disabled (use theme)
● Shortcodes (hybrid - works with any theme)
○ Full SPA (replace theme frontend)
```

**WooNooW Themes (Optional):**
```
woonoow-theme-storefront/   (Free, basic)
woonoow-theme-fashion/      (Premium, $79)
woonoow-theme-electronics/  (Premium, $79)
```

### How It Works:

#### Mode 1: Disabled
- Plugin only provides admin-spa
- Theme handles all frontend
- For users who want full theme control

#### Mode 2: Shortcodes (Default)
- Plugin provides cart/checkout/account components
- Works with ANY theme
- Hybrid approach (SSR + SPA islands)
- Best compatibility

#### Mode 3: Full SPA
- Plugin takes over entire frontend
- Theme only provides header/footer
- Maximum performance
- For performance-critical sites
