Icon Management System Guide

🎯 Overview

The icon management system has been 100% MODERNIZED to Vue 3 composables. We now have:

1. ✅ Fully Self-Contained Composables - No legacy dependencies
2. ✅ Pure Vue 3 Architecture - Modern Composition API throughout
3. ✅ Zero Legacy Code - All window.iconManager dependencies removed
4. ✅ Optimal Performance - Direct icon loading without external systems

🔧 Available Methods

Vue 3 Composables (Self-Contained)

1. useIconManager() - Full Featured

<script setup>
import { useIconManager } from '@/composables/useIconManager.js';

const { 
    loadIcon, 
    loadIcons, 
    ensureIconsLoaded,
    watchIcon,
    watchFormDataIcon,
    preloadCommonIcons,
    isIconManagerReady 
} = useIconManager();

// Load single icon
loadIcon('send');

// Load multiple icons
loadIcons(['send', 'attach_file']);

// Preload common icons
preloadCommonIcons();
</script>

2. useIcon() - Simple Icon Loading

<script setup>
import { useIcon } from '@/composables/useIconManager.js';

// Automatically loads icon on mount
const { loadIcon, isIconManagerReady } = useIcon('send');
</script>

3. useFormIcon() - Form Data Integration

<script setup>
import { ref } from 'vue';
import { useFormIcon } from '@/composables/useIconManager.js';

const formData = ref({ icon: 'send' });

// Automatically watches formData.icon and loads icons
const { loadIcon, isIconManagerReady } = useFormIcon(formData);
</script>

🔄 Migration Guide

From IconManagerMixin (Old)

<!-- OLD: Using mixin -->
<script>
import { IconManagerMixin } from '@/iconManager.js';

export default {
    mixins: [IconManagerMixin],
    // Component automatically loads formData.icon
}
</script>

To Vue 3 Composable (New)

<!-- NEW: Using composable -->
<script setup>
import { useFormIcon } from '@/composables/useIconManager.js';

const props = defineProps(['formData']);
const { loadIcon } = useFormIcon(() => props.formData);
</script>

📋 Current Usage in Vue Components

All Components Now Use Modern Composables ✅

1. ChatInput.vue - Uses useIconManager() composable
2. ChatMessage.vue - Uses useIconManager() composable
3. DynamicForm.vue - Uses useIconManager() composable with boolean icon support

🔘 Boolean Value Display

Overview

Boolean values in read-only DynamicForm components are automatically displayed using Material Icons instead of text for improved user experience.

Icon Mapping

const booleanIconMapping = {
  true: 'check_circle',    // Green checkmark icon
  false: 'cancel'          // Red cancel/cross icon
};

Visual Styling

• True values: Green check_circle icon (#4caf50)
• False values: Red cancel icon (#f44336)
• Size: 20px font size with middle vertical alignment
• Accessibility: Includes aria-label and title attributes

Usage Example

<!-- Form definition with boolean fields -->
<script>
export default {
  data() {
    return {
      formData: {
        title: 'User Settings',
        fields: [
          { id: 'active', name: 'Actief', type: 'boolean' },
          { id: 'verified', name: 'Geverifieerd', type: 'boolean' }
        ]
      },
      formValues: {
        active: true,    // Will show green check_circle
        verified: false  // Will show red cancel
      }
    };
  }
};
</script>

<!-- Read-only display -->
<dynamic-form 
  :form-data="formData" 
  :form-values="formValues" 
  :read-only="true"
  api-prefix="/api"
/>

Implementation Details

• Automatic icon loading: Boolean icons (check_circle, cancel) are preloaded when DynamicForm mounts
• Read-only only: Edit mode continues to use standard HTML checkboxes
• Accessibility: Each icon includes Dutch labels ('Ja'/'Nee') for screen readers
• Responsive: Icons scale appropriately with form styling

CSS Classes

.boolean-icon {
    font-size: 20px;
    vertical-align: middle;
}

.boolean-true {
    color: #4caf50; /* Green for true */
}

.boolean-false {
    color: #f44336; /* Red for false */
}

.field-value.boolean-value {
    display: flex;
    align-items: center;
}

Zero Legacy Code Remaining ✅

• ❌ No IconManagerMixin references
• ❌ No window.iconManager calls
• ❌ No legacy iconManager.js file
• ✅ 100% Vue 3 composables

✅ Complete Modernization Achieved

1. Legacy System Eliminated

• Before: Hybrid system with window.iconManager + composables
• After: Pure Vue 3 composables, zero legacy dependencies

2. Self-Contained Architecture

• Before: Composables depended on external iconManager.js
• After: Fully self-contained composables with direct icon loading

3. Optimal Performance

• Before: Multiple layers (composable → window.iconManager → DOM)
• After: Direct composable → DOM, no intermediate layers

🚀 Modern Usage Patterns (100% Vue 3)

For Form Components

<script setup>
import { useFormIcon } from '@/composables';

const props = defineProps(['formData']);
const { loadIcon } = useFormIcon(() => props.formData);
</script>

For Direct Icon Loading

<script setup>
import { useIcon } from '@/composables';

// Load specific icon on mount
const { loadIcon } = useIcon('send');

// Or load dynamically
const loadDynamicIcon = (iconName) => {
    loadIcon(iconName);
};
</script>

For Advanced Icon Management

<script setup>
import { useIconManager } from '@/composables';

const { loadIcon, loadIcons, watchIcon, preloadCommonIcons } = useIconManager();

// Preload common icons
preloadCommonIcons(['send', 'close', 'check']);

// Watch reactive icon source
watchIcon(() => someReactiveIcon.value);
</script>
