Using the Page Builder

Creating a New Page

1. Navigate to Admin → CMS → Pages → Create New Page
2. Fill in basic page information (title, slug, meta description)
3. Use the visual editor to build your page content
4. Drag components from the left sidebar to the canvas
5. Configure component properties in the right sidebar
6. Save and publish your page

Editing Existing Pages

1. Navigate to Admin → CMS → Pages
2. Click the edit button for the page you want to modify
3. Make changes using the visual editor
4. Save your changes

Component Configuration

Each component has configurable properties:

// Example: HeadingBlock configuration
{
  text: "Welcome to Our Site",
  level: 1, // h1, h2, h3, etc.
  align: "center",
  color: "primary",
  size: "large"
}

Page Management

Page Structure

Pages in the CMS have the following structure:

interface Page {
  id: string
  title: string
  slug: string
  content: string // Puck JSON data
  metaDescription?: string
  isPublished: boolean
  creationTime: Date
  lastModificationTime?: Date
}

Page Operations

Creating Pages

// Using the admin interface
const createPage = async (pageData: CreatePageInputDto) => {
  const response = await pageAdminCreate(pageData)
  return response
}

Updating Pages

// Update existing page content
const updatePage = async (id: string, updates: UpdatePageInputDto) => {
  const response = await pageAdminUpdate(id, updates)
  return response
}

Publishing Pages

Pages can be published or kept as drafts:

// Set page as published
const publishPage = async (id: string) => {
  const response = await pageAdminUpdate(id, {
    isPublished: true
  })
  return response
}

URL Management

Pages use SEO-friendly URLs based on their slug:

• Auto-generation: Slugs are automatically generated from titles
• Custom slugs: Override auto-generated slugs when needed
• URL validation: Ensures unique and valid URLs

Menu Management

Menu Structure

The CMS includes a flexible menu system:

interface MenuItem {
  id: string
  name: string
  link: string
  icon?: string
  order: number
  parentId?: string
  isActive: boolean
}

Menu Operations

Creating Menu Items

1. Navigate to Admin → CMS → Menu Items → Create New Menu Item
2. Configure menu item properties
3. Set parent menu for hierarchical navigation
4. Define display order

Menu Hierarchy

• Parent menus: Top-level navigation items
• Sub-menus: Nested navigation under parent items
• Dynamic ordering: Drag-and-drop menu organization

Comment System

Comment Features

The CMS includes a comprehensive comment system:

• User authentication: Only authenticated users can comment
• Moderation tools: Admin interface for comment management
• Spam protection: Built-in spam detection
• Threaded comments: Support for comment replies
• Rich text: Markdown support for comment formatting

Comment Management

Admin Interface

Navigate to Admin → CMS → Comments to:

• View all comments across the site
• Moderate inappropriate content
• Delete spam or offensive comments
• Manage comment settings

Comment Permissions

// Available comment permissions
CMSKIT_COMMENTS = 'CmsKit.Comments'
CMSKIT_COMMENTS_DELETE = 'CmsKit.Comments.Delete'
CMSKIT_COMMENTS_UPDATE = 'CmsKit.Comments.Update'
CMSKIT_COMMENTS_SETTING_MANAGEMENT = 'CmsKit.Comments.SettingManagement'

Public Comment Permissions

// Public comment permissions
CMSKIT_PUBLIC_COMMENTS = 'CmsKitPublic.Comments'
CMSKIT_PUBLIC_COMMENTS_DELETE_ALL = 'CmsKitPublic.Comments.DeleteAll'

Comment Display

Comments are automatically displayed on pages:

// Comments component usage
<PageComments pageId={page.id} pageTitle={page.title} />

Content Blocks and Components

Block Configuration

Each content block has a configuration file that defines:

• Properties: Configurable options for the block
• Default values: Initial settings for new blocks
• Validation: Input validation rules
• Styling: CSS classes and styling options

Custom Block Development

Creating New Blocks

1. Create a new component in src/components/puck/components/
2. Define the component's TypeScript interface
3. Create a configuration file with block settings
4. Add the block to the main Puck configuration
5. Create Storybook stories for documentation

Block Structure

// Example block component
export const CustomBlock: React.FC<CustomBlockProps> = ({ 
  title, 
  content, 
  className = '' 
}) => {
  return (
    <div className={`custom-block ${className}`}>
      <h3>{title}</h3>
      <div>{content}</div>
    </div>
  )
}

// Block configuration
export const CustomBlockConfig: ComponentConfig<CustomBlockProps> = {
  fields: {
    title: { type: 'text', label: 'Title' },
    content: { type: 'textarea', label: 'Content' }
  },
  defaultProps: {
    title: 'Default Title',
    content: 'Default content'
  }
}

Multi-tenant Support

Tenant-specific Content

The CMS supports multi-tenant environments:

• Content isolation: Each tenant has separate content
• Feature management: Enable/disable CMS features per tenant
• Permission control: Tenant-specific access controls
• Content sharing: Optional content sharing between tenants

Tenant Configuration

// Enable CMS features for a tenant
const enableCmsFeatures = async (tenantId: string) => {
  await tenantFeatureManagement.setFeatures(tenantId, {
    'CmsKit.Pages': true,
    'CmsKit.Comments': true,
    'CmsKit.Menus': true
  })
}

CMS Permissions

Permission System

The CMS uses ABP Framework's permission system:

// Page permissions
CMSKIT_PAGES = 'CmsKit.Pages'
CMSKIT_PAGES_CREATE = 'CmsKit.Pages.Create'
CMSKIT_PAGES_UPDATE = 'CmsKit.Pages.Update'
CMSKIT_PAGES_DELETE = 'CmsKit.Pages.Delete'
CMSKIT_PAGES_SET_AS_HOME_PAGE = 'CmsKit.Pages.SetAsHomePage'

// Blog permissions
CMSKIT_BLOGS = 'CmsKit.Blogs'
CMSKIT_BLOGS_CREATE = 'CmsKit.Blogs.Create'
CMSKIT_BLOGS_UPDATE = 'CmsKit.Blogs.Update'
CMSKIT_BLOGS_DELETE = 'CmsKit.Blogs.Delete'

// Tag permissions
CMSKIT_TAGS = 'CmsKit.Tags'
CMSKIT_TAGS_CREATE = 'CmsKit.Tags.Create'
CMSKIT_TAGS_UPDATE = 'CmsKit.Tags.Update'
CMSKIT_TAGS_DELETE = 'CmsKit.Tags.Delete'

Role-based Access

Assign CMS permissions to user roles:

// Example: Content Editor role
const contentEditorPermissions = [
  'CmsKit.Pages.Create',
  'CmsKit.Pages.Update',
  'CmsKit.Comments.Update',
  'CmsKit.Tags.Create'
]

Best Practices

Content Organization

• Consistent naming: Use clear, descriptive names for pages and components
• Content hierarchy: Organize content logically with proper navigation
• SEO optimization: Use descriptive titles and meta descriptions
• Mobile-first: Design content with mobile devices in mind

Performance Optimization

• Image optimization: Use appropriate image formats and sizes
• Lazy loading: Implement lazy loading for media content
• Caching: Leverage ABP Framework's caching capabilities
• CDN integration: Use CDNs for static content delivery

Security Considerations

• Input validation: Validate all user inputs
• Permission checks: Always verify user permissions
• Content sanitization: Sanitize user-generated content
• Rate limiting: Implement rate limiting for comment systems

Troubleshooting

Common Issues

Page Builder Not Loading

• Check browser console for JavaScript errors
• Verify Puck configuration is correct
• Ensure all required dependencies are installed

Content Not Rendering

• Validate Puck data structure
• Check component configuration
• Verify component imports and exports

Permission Errors

• Verify user has required permissions
• Check role assignments
• Confirm feature flags are enabled

Debug Mode

Enable debug mode for troubleshooting:

// Enable debug logging
const debugConfig = {
  debug: true,
  logLevel: 'debug'
}

Integration Examples

Custom Page Templates

Create reusable page templates:

// Template configuration
const pageTemplate = {
  content: [
    {
      type: 'Hero',
      props: {
        title: 'Welcome',
        subtitle: 'Custom template',
        backgroundImage: '/images/hero-bg.jpg'
      }
    },
    {
      type: 'TextBlock',
      props: {
        content: 'Default content for template'
      }
    }
  ]
}

API Integration

Integrate with external APIs:

// Fetch content from external CMS
const fetchExternalContent = async () => {
  const response = await fetch('/api/external-content')
  const content = await response.json()
  return convertToPuckFormat(content)
}
