# Atomic Design: Templates

Master the creation of templates - page-level layouts that define content structure without actual content. Templates establish the skeletal structure that pages will use.

## What Are Templates?

Templates are the page-level objects that place components into a layout and articulate the design's underlying content structure. They are:

- **Composed of organisms**: Arrange organisms into page layouts
- **Content-agnostic**: Use placeholder content, not real data
- **Structural**: Define where content types will appear
- **Reusable**: Same template can be used by multiple pages
- **Responsive**: Handle all viewport sizes

## Common Template Types

### Marketing Templates

- Landing page layouts
- Homepage layouts
- Product showcase layouts
- About/Company layouts

### Application Templates

- Dashboard layouts
- Settings page layouts
- Profile page layouts
- List/Detail page layouts

### Content Templates

- Blog post layouts
- Article layouts
- Documentation layouts
- Help center layouts

### E-commerce Templates

- Product listing layouts
- Product detail layouts
- Checkout layouts
- Order confirmation layouts

## MainLayout Template Example

### Complete Implementation

```typescript
// templates/MainLayout/MainLayout.tsx
import React from 'react';
import { Header, type HeaderProps } from '@/components/organisms/Header';
import { Footer, type FooterProps } from '@/components/organisms/Footer';
import styles from './MainLayout.module.css';

export interface MainLayoutProps {
  /** Header configuration */
  headerProps: HeaderProps;
  /** Footer configuration */
  footerProps: FooterProps;
  /** Main content */
  children: React.ReactNode;
  /** Show breadcrumbs */
  showBreadcrumbs?: boolean;
  /** Breadcrumb component */
  breadcrumbs?: React.ReactNode;
  /** Maximum content width */
  maxWidth?: 'sm' | 'md' | 'lg' | 'xl' | 'full';
  /** Page background color */
  background?: 'white' | 'gray' | 'primary';
}

export const MainLayout: React.FC<MainLayoutProps> = ({
  headerProps,
  footerProps,
  children,
  showBreadcrumbs = false,
  breadcrumbs,
  maxWidth = 'lg',
  background = 'white',
}) => {
  return (
    <div className={`${styles.layout} ${styles[`bg-${background}`]}`}>

      <main className={styles.main}>

## TwoColumnLayout Template Example

```typescript
// templates/TwoColumnLayout/TwoColumnLayout.tsx
import React from 'react';
import styles from './TwoColumnLayout.module.css';

export interface TwoColumnLayoutProps {
  /** Left column (usually main content) */
  main: React.ReactNode;
  /** Right column (usually sidebar) */
  sidebar: React.ReactNode;
  /** Sidebar position */
  sidebarPosition?: 'left' | 'right';
  /** Sidebar width */
  sidebarWidth?: 'narrow' | 'medium' | 'wide';
  /** Sticky sidebar */
  stickySidebar?: boolean;
  /** Reverse on mobile (show sidebar first) */
  reverseMobile?: boolean;
  /** Gap between columns */
  gap?: 'sm' | 'md' | 'lg';
}

export const TwoColumnLayout: React.FC<TwoColumnLayoutProps> = ({
  main,
  sidebar,
  sidebarPosition = 'right',
  sidebarWidth = 'medium',

## Best Practices

### 1. Use Placeholder Content

```typescript
// GOOD: Template with placeholder content slots
const ProductDetailLayout = ({
  productGallery,    // Placeholder for gallery component
  productInfo,       // Placeholder for product details
  productTabs,       // Placeholder for tabs
  relatedProducts,   // Placeholder for recommendations
}) => (
  <div>
    <section>{productGallery}</section>
    <section>{productInfo}</section>
    <section>{productTabs}</section>
    <section>{relatedProducts}</section>
  </div>
);

// BAD: Template with hardcoded content
const ProductDetailLayout = ({ product }) => (
  <div>
    <ProductGallery images={product.images} />      {/* Too specific */}
    <h1>{product.name}</h1>                          {/* Real content */}
    <p>{product.description}</p>
  </div>
);
```

### 2. Define Clear Content Areas

```typescript
// GOOD: Clear, named content slots
interface PageTemplateProps {
  header: React.ReactNode;
  hero?: React.ReactNode;
  main: React.ReactNode;
  sidebar?: React.ReactNode;
  footer: React.ReactNode;
}

// BAD: Generic children only
interface PageTemplateProps {
  children: React.ReactNode;
}
```

### 3. Handle Responsive Layouts

```typescript
// GOOD: Responsive considerations built-in
const DashboardLayout = ({ sidebar, main }) => (
  <div className={styles.layout}>
    <aside className={styles.sidebar}>{sidebar}</aside>
    <main className={styles.main}>{main}</main>
  </div>
);

// CSS handles responsive behavior
// .sidebar { @media (max-width: 768px) { display: none; } }
```

### 4. Keep Templates Thin

```typescript
// GOOD: Template just arranges organisms
const MainLayout = ({ header, main, footer }) => (
  <div className={styles.layout}>
    <div className={styles.header}>{header}</div>
    <div className={styles.main}>{main}</div>
    <div className={styles.footer}>{footer}</div>
  </div>
);

// BAD: Template with business logic
const MainLayout = ({ userId }) => {
  const user = useUser(userId);          // Fetching data
  const isAdmin = user?.role === 'admin'; // Business logic

  return (
    <div>
      <Header user={user} showAdmin={isAdmin} />
      {/* ... */}
    </div>
  );
};
```

## Anti-Patterns to Avoid

### 1. Templates with Real Content

```typescript
// BAD: Hardcoded real content
const HomepageLayout = () => (
  <div>
    <h1>Welcome to Our Store</h1>           {/* Real content! */}
    <p>Shop our latest collection...</p>    {/* Real content! */}
  </div>
);

// GOOD: Content passed as props/children
const HomepageLayout = ({ heroTitle, heroDescription }) => (
  <div>
    <h1>{heroTitle}</h1>
    <p>{heroDescription}</p>
  </div>
);
```

### 2. Over-Nested Templates

```typescript
// BAD: Templates containing templates
const AppLayout = () => (
  <BaseLayout>
    <AuthLayout>
      <DashboardLayout>
        {/* Too much nesting */}
      </DashboardLayout>
    </AuthLayout>
  </BaseLayout>
);

// GOOD: Choose appropriate template directly
const AppPage = () => (
  <DashboardLayout>
    {/* Content */}
  </DashboardLayout>
);
```

### 3. Templates with Too Many Props

```typescript
// BAD: Too many configuration options
interface LayoutProps {
  showHeader: boolean;
  showFooter: boolean;
  showSidebar: boolean;
  sidebarPosition: 'left' | 'right';
  headerVariant: 'default' | 'minimal' | 'transparent';
  footerVariant: 'default' | 'minimal';
  maxWidth: 'sm' | 'md' | 'lg' | 'xl';
  // ... 20 more props
}

// GOOD: Create separate templates
const FullPageLayout = ({ ... }) => { ... };
const MinimalLayout = ({ ... }) => { ... };
const SidebarLayout = ({ ... }) => { ... };
```

## Template Composition Patterns

### Nested Layouts

```typescript
// Base layout for all pages
const BaseLayout = ({ children }) => (
  <div className="base">
    <SkipLink />
    {children}
  </div>
);

// Marketing layout extending base
const MarketingLayout = ({ children }) => (
  <BaseLayout>
    <MarketingHeader />
    <main>{children}</main>
    <MarketingFooter />
  </BaseLayout>
);

// App layout extending base
const AppLayout = ({ children }) => (
  <BaseLayout>
    <AppHeader />
    <main>{children}</main>
  </BaseLayout>
);
```

### Slot-Based Layouts

```typescript
interface SlotLayoutProps {
  slots: {
    header?: React.ReactNode;
    sidebar?: React.ReactNode;
    main: React.ReactNode;
    footer?: React.ReactNode;
  };
}

const SlotLayout: React.FC<SlotLayoutProps> = ({ slots }) => (
  <div className={styles.layout}>
    {slots.header && <header>{slots.header}</header>}
    <div className={styles.body}>
      {slots.sidebar && <aside>{slots.sidebar}</aside>}
      <main>{slots.main}</main>
    </div>
    {slots.footer && <footer>{slots.footer}</footer>}
  </div>
);
```
