🧩 Component Architecture

Vue 3 Composition API components with Nuxt UI Pro v4 integration, following consistent patterns for reusability and maintainability.

🏗️ Component Structure

│       ├── CreateModal.vue  # Modal components with UAuthForm
│       └── DeleteModal.vue  # Confirmation modals
├── layout/

└── ui/
    └── form/               # Reusable form field components
        ├── Input.vue
        ├── Email.vue
        ├── Password.vue
        └── Textarea.vue

🎯 Component Patterns

1. Props & Events Pattern

Implementation: See components in app/components/features/post/ for complete prop and event type definitions.

2. v-model Pattern

Implementation: See app/components/ui/form/ for v-model patterns and app/components/features/post/CreateModal.vue for named models.

3. Composable Integration

Implementation: See components for composable integration patterns with useI18n, useNotifications, and form composables.

🎨 Component Categories

Display Components

Implementation: See app/components/features/post/Card.vue for complete post display component with Nuxt UI integration.

Features:

  • ✅ Nuxt UI Pro v4 integration with UCard, UButton, UDropdownMenu
  • ✅ Overlay system with useOverlay() for modal management
  • ✅ Consistent styling with primary/secondary color scheme
  • ✅ Micro-interactions with hover effects and transitions

Modal Components

Implementation: See app/components/features/post/CreateModal.vue for complete modal component with form integration.

Features:

  • ✅ UAuthForm integration for consistent form patterns
  • ✅ Composable-driven with usePostForm, useLoginForm, useRegisterForm
  • ✅ Overlay management with useOverlay() for better UX
  • ✅ Real-time analytics with character count, word count, reading time

Form Field Components

Implementation: See app/components/ui/form/ directory for consistent field component patterns with UFormField integration.

🎭 Styling Patterns

Nuxt UI Pro v4 Integration

Implementation: See components for consistent color and variant usage patterns with Nuxt UI components.

Responsive Design

Implementation: Components follow mobile-first responsive design with Tailwind CSS utilities and dark mode support.

Dark Mode Support

Implementation: All components include dark mode variants using Tailwind's dark: prefix classes.

🔧 State Management

Local State

Implementation: Components use Vue's reactive refs and reactive objects for local state management.

Computed Properties

Implementation: Components leverage Vue's computed properties for reactive derived state and dynamic content.

Watchers

Implementation: Components use Vue watchers for reactive state updates based on prop changes and external data.

🚀 Best Practices

Component Organization

  1. Single Responsibility - Each component has one clear purpose
  2. Composition over Inheritance - Use composables for shared logic
  3. Props Down, Events Up - Unidirectional data flow
  4. Type Safety - Always use TypeScript interfaces

Performance

  1. Lazy Loading - Use defineAsyncComponent for heavy components
  2. v-memo - Cache expensive template computations
  3. Computed Caching - Leverage Vue's computed property caching
  4. Event Cleanup - Remove event listeners in onUnmounted

Accessibility

  1. Semantic HTML - Use proper HTML elements
  2. ARIA Labels - Provide accessible labels
  3. Focus Management - Handle focus for modals and forms
  4. Color Contrast - Ensure sufficient contrast ratios

Testing

  1. Test IDs - Add data-testid for reliable selection
  2. Event Testing - Test component events and interactions
  3. Snapshot Testing - Capture component output changes
  4. Integration Testing - Test component interactions
