Template System Architecture

Dynamic Loading

// Template Registry
export const templateRegistry: Record<TemplateId, TemplateRegistryEntry> = {
  default: {
    id: 'default',
    name: 'nself',
    description: 'Modern design combining best of all platforms',
    load: () => import('./default/config').then((m) => m.default),
  },
  // ... other templates
}

// Load template dynamically
const template = await loadTemplate('whatsapp')

// Switch templates at runtime
await switchTemplate('slack')

Theme Application

// Use template hook
const { template, colors, layout, features, t } = useTemplate()

// Check if feature is enabled
const hasThreads = isFeatureEnabled('threads')

// Get terminology
const channelLabel = t('channel') // "Chat" for WhatsApp, "Channel" for Slack

// Get theme colors
const bgColor = colors.backgroundColor

CSS Custom Properties

// Generate CSS variables
const css = generateTemplateCSS(template)

// CSS variables applied to :root
:root {
  --primary: #00D4FF;
  --primary-rgb: 0 212 255;
  --secondary: #0EA5E9;
  --background: #18181B;
  --surface: #27272A;
  --foreground: #F4F4F5;
  // ... 40+ variables
}

Component Overrides

// Template-specific components
const components = {
  MessageItem: WhatsAppMessage,
  ChannelItem: WhatsAppChatList,
  UserAvatar: WhatsAppAvatar,
  // ...
}

// Render with override
const MessageComponent = template.components?.MessageItem ?? DefaultMessageItem

Usage Examples

1. Switch Template Programmatically

import { useTemplate } from '@/templates/hooks/use-template'

function TemplateSwitcher() {
  const { switchTemplate, templateId, isLoading } = useTemplate()

  return (
    <select
      value={templateId}
      onChange={(e) => switchTemplate(e.target.value as TemplateId)}
      disabled={isLoading}
    >
      <option value="default">Ι³Chat</option>
      <option value="whatsapp">WhatsApp</option>
      <option value="telegram">Telegram</option>
      <option value="slack">Slack</option>
      <option value="discord">Discord</option>
    </select>
  )
}

2. Use Template Colors

import { useThemeColors } from '@/templates/hooks/use-template'

function MyComponent() {
  const colors = useThemeColors()

  return (
    <div style={{ backgroundColor: colors.surfaceColor }}>
      <h1 style={{ color: colors.primaryColor }}>Hello</h1>
    </div>
  )
}

3. Check Feature Availability

import { useFeature } from '@/templates/hooks/use-template'

function ThreadButton({ messageId }: { messageId: string }) {
  const hasThreads = useFeature('threads')

  if (!hasThreads) return null

  return <button onClick={() => openThread(messageId)}>Reply in thread</button>
}

4. Use Terminology

import { useTerminology } from '@/templates/hooks/use-template'

function CreateChannelButton() {
  const { t } = useTerminology()

  return (
    <button>
      {t('createChannel')} {/* "Create Channel" or "New Chat" */}
    </button>
  )
}

5. Apply Custom Overrides

import { useTemplate } from '@/templates/hooks/use-template'

function CustomizeTheme() {
  const { applyOverrides } = useTemplate()

  const handleCustomize = () => {
    applyOverrides({
      theme: {
        light: {
          primaryColor: '#FF0000', // Custom red
        }
      },
      layout: {
        sidebarWidth: 320, // Wider sidebar
      }
    })
  }

  return <button onClick={handleCustomize}>Customize</button>
}

6. Environment Variable Configuration

# .env.local
NEXT_PUBLIC_PLATFORM_TEMPLATE=whatsapp
