# Shop Navigation Flow

Complete guide to navigation structure and URL hierarchy with landing pages.

├── /shop/                         → E-commerce Homepage (Product Catalog)
│   ├── /shop/products             → Product Catalog (same as /shop/)

## Navigation Patterns

### Pattern 1: With Landing Page (Recommended)

**URL Structure:**
```
customdomain.com/              → Landing Page (marketing/brand)
customdomain.com/shop/         → E-commerce Shop
customdomain.com/shop/products → Product Catalog
```

**Navigation Flow:**
1. User visits store domain → **Landing Page**
2. Clicks "Shop Now" → **/shop/** (product catalog)
3. Clicks "Home" in breadcrumb → **/** (back to landing page)
4. Clicks logo → **/** (back to landing page)

**Breadcrumb Example (on Products page):**
```
Home > Products
 ↓
 / (Landing Page)
```

### Pattern 2: Without Landing Page (Auto-Redirect)

**URL Structure:**
```
customdomain.com/              → Redirects to /shop/
customdomain.com/shop/         → E-commerce Shop
customdomain.com/shop/products → Product Catalog
```

**Navigation Flow:**
1. User visits store domain → **Redirects to /shop/**
2. User browses shop
3. Clicks "Home" in breadcrumb → **/** (redirects to /shop/)
4. Clicks logo → **/** (redirects to /shop/)

**Breadcrumb Example (on Products page):**
```
Home > Products
 ↓
 / → /shop/ (redirects)
```

## Link References

### Base URL Calculation

The `base_url` variable is calculated in `shop_pages.py:get_shop_context()`:

```python
# For domain/subdomain access
base_url = "/"
# Result: /shop/products, /shop/cart, etc.

# For path-based access
base_url = "/stores/orion/"
# Result: /stores/orion/shop/products, /stores/orion/shop/cart, etc.
```

### Template Links

**Logo / Home Link (Header):**
```jinja2
{# Points to store root (landing page or shop) #}
<a href="{{ base_url }}shop/">{{ store.name }}</a>
```

**Breadcrumb Home Link:**
```jinja2
{# Points to store root (landing page) #}
<a href="{{ base_url }}">Home</a>
```

**Shop Links:**
```jinja2
{# All shop pages include /shop/ prefix #}
<a href="{{ base_url }}shop/products">Products</a>
<a href="{{ base_url }}shop/cart">Cart</a>
<a href="{{ base_url }}shop/checkout">Checkout</a>
```

**CMS Page Links:**
```jinja2
{# CMS pages are under /shop/ #}
<a href="{{ base_url }}shop/about">About</a>
<a href="{{ base_url }}shop/contact">Contact</a>
<a href="{{ base_url }}shop/{{ page.slug }}">{{ page.title }}</a>
```

### Path-Based Access (Development)

```
http://localhost:8000/stores/orion/
├── / (root)                              → Landing Page OR redirect to shop
├── /shop/                                → Shop Homepage
├── /shop/products                        → Product Catalog
├── /shop/products/4                      → Product Detail

```

### Subdomain Access (Production)

## Navigation Components

### Header Navigation (base.html)

```jinja2
{# Logo - always points to store root #}
<a href="{{ base_url }}shop/">
    <img src="{{ theme.branding.logo }}" alt="{{ store.name }}">
</a>

{# Main Navigation #}
<nav>
    <a href="{{ base_url }}shop/">Home</a>
    <a href="{{ base_url }}shop/products">Products</a>
    <a href="{{ base_url }}shop/about">About</a>
    <a href="{{ base_url }}shop/contact">Contact</a>
</nav>

{# Actions #}
<a href="{{ base_url }}shop/cart">Cart</a>
<a href="{{ base_url }}shop/account">Account</a>
```

### Footer Navigation (base.html)

```jinja2
{# Quick Links #}
<a href="{{ base_url }}shop/products">Products</a>

{# CMS Pages (dynamic) #}
{% for page in footer_pages %}
<a href="{{ base_url }}shop/{{ page.slug }}">{{ page.title }}</a>
{% endfor %}
```

### Breadcrumbs (products.html, content-page.html)

```jinja2
{# Points to store root (landing page) #}
<a href="{{ base_url }}">Home</a> / Products
```

## Best Practices

### ✅ DO:

1. **Use Landing Pages**: Create engaging landing pages at store root
2. **Clear Navigation**: Make it easy to get from landing to shop and back
3. **Consistent "Home"**: Logo and "Home" breadcrumb both point to `/` (landing)
4. **Shop Links**: All shop-related links include `/shop/` prefix
5. **CMS Under Shop**: Keep CMS pages under `/shop/` for consistency

### ❌ DON'T:

1. **Hardcode URLs**: Always use `{{ base_url }}` for store-aware links
2. **Skip /shop/**: Don't link directly to `/products`, use `/shop/products`
3. **Mix Landing & Shop**: Keep landing page separate from shop catalog
4. **Forget Breadcrumbs**: Always provide "Home" link to go back

## Migration Notes

### Before Landing Pages

All links pointed to `/shop/`:
```jinja2
<a href="{{ base_url }}shop/">Home</a>  {# Logo #}
<a href="{{ base_url }}shop/">Home</a>  {# Breadcrumb #}
```

### After Landing Pages

Separation of concerns:
```jinja2
<a href="{{ base_url }}shop/">Home</a>  {# Logo - still goes to shop #}
<a href="{{ base_url }}">Home</a>       {# Breadcrumb - goes to landing #}
```

This allows:
- Landing page at `/` for marketing/branding
- Shop catalog at `/shop/` for e-commerce
- Clean navigation between the two

## Technical Implementation

### Route Handlers (main.py)

```python
# Store root - serves landing page or redirects to shop
@app.get("/")
@app.get("/stores/{store_code}/")
async def root(request: Request):
    if has_landing_page():
        return render_landing_page()
    else:
        return redirect_to_shop()

# Shop routes
@app.include_router(shop_pages.router, prefix="/shop")
@app.include_router(shop_pages.router, prefix="/stores/{store_code}/shop")
```

### Context Calculation (shop_pages.py)

```python
def get_shop_context(request: Request):
    base_url = "/"
    if access_method == "path":
        base_url = f"/stores/{store.subdomain}/"

    return {
        "base_url": base_url,
        "store": store,
        "theme": theme,
        # ...
    }
```

## Summary

The navigation system creates a **two-tier structure**:

1. **Landing Page** (`/`) - Marketing, branding, store story
2. **Shop** (`/shop/`) - E-commerce, products, cart, checkout

This gives stores flexibility to:
- Have a marketing homepage separate from their store
- Choose different landing page designs (minimal, modern, full)
- Or skip the landing page and go straight to the shop

All while maintaining clean, consistent navigation throughout the experience.
