+    └── useIconManager.js            # Self-contained Vue 3 composables
+```
+
+## 🔧 Available Methods
+
+### Vue 3 Composables (Self-Contained)
+
+#### 1. useIconManager() - Full Featured
+
+```vue
+<script setup>
+import { useIconManager } from '@/composables/useIconManager.js';
+
+const { 
+    loadIcon, 
+    loadIcons, 
+    ensureIconsLoaded,

+// Load single icon
+loadIcon('send');
+
+// Load multiple icons
+loadIcons(['send', 'attach_file']);
+
+// Preload common icons
+preloadCommonIcons();
+</script>
+```
+
+#### 2. useIcon() - Simple Icon Loading
+
+```vue
+<script setup>
+import { useIcon } from '@/composables/useIconManager.js';
+
+// Automatically loads icon on mount
+const { loadIcon, isIconManagerReady } = useIcon('send');
+</script>
+```
+
+#### 3. useFormIcon() - Form Data Integration

+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)
+
+```vue
+<!-- OLD: Using mixin -->
+<script>
+import { IconManagerMixin } from '@/iconManager.js';
+
+export default {
+    mixins: [IconManagerMixin],
+    // Component automatically loads formData.icon
+}
+</script>
+```
+
+### To Vue 3 Composable (New)
+
+```vue
+<!-- 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
+
+### Zero Legacy Code Remaining ✅
+

+### 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
+```vue
+<script setup>
+import { useFormIcon } from '@/composables';
+
+const props = defineProps(['formData']);

+</script>
+```
+
+### For Direct Icon Loading
+```vue
+<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
+```vue
+<script setup>
+import { useIconManager } from '@/composables';
+
+const { loadIcon, loadIcons, watchIcon, preloadCommonIcons } = useIconManager();
+
+// Preload common icons

+
+1. **✅ Modern Vue 3 Composables** - Reactive translation state management
+2. **✅ Better Error Handling** - Comprehensive error states and fallbacks
+3. **✅ Loading States** - Built-in loading indicators for translations
+4. **✅ Batch Translation** - Efficient multiple text translation
+5. **✅ Backward Compatibility** - Existing code continues to work during migration
+
+## 📁 File Structure

+    └── useTranslation.js            # Vue 3 translation composables
+```
+
+## 🔧 Available Composables
+
+### 1. useTranslation() - Full Featured
+
+The main composable providing complete translation functionality with reactive state management.
+
+```vue
+<script setup>
+import { useTranslation } from '@/composables/useTranslation.js';
+
+const { 
+    translate,
+    translateSafe,
+    translateBatch,
+    isTranslationReady,
+    isTranslating,
+    currentLanguage,
+    lastError
+} = useTranslation();
+
+// Translate with full control
+const result = await translate('Hello world', 'nl', 'en', 'greeting');
+
+// Safe translation with fallback
+const translated = await translateSafe('Hello world', 'nl', {
+    fallbackText: 'Hello world',
+    context: 'greeting'
+});
+
+// Batch translate multiple texts
+const texts = ['Hello', 'World', 'Vue'];
+const translated = await translateBatch(texts, 'nl');
+</script>
+```
+
+### 2. useTranslationClient() - Simplified
+
+Simplified composable for basic translation needs without reactive state management.
+
+```vue
+<script setup>
+import { useTranslationClient } from '@/composables/useTranslation.js';
+
+const { 
+    translate,
+    translateSafe,
+    isTranslationReady,
+    isTranslating,
+    lastError
+} = useTranslationClient();
+
+// Simple translation
+const result = await translateSafe('Hello world', 'nl');
+</script>
+```
+
+### 3. useReactiveTranslation() - Automatic Translation
+
+Composable for reactive text translation that automatically updates when language changes.
+
+```vue
+<script setup>
+import { useReactiveTranslation } from '@/composables/useTranslation.js';
+
+const originalText = 'Hello world';
+const { 
+    translatedText, 
+    isLoading, 
+    updateTranslation 
+} = useReactiveTranslation(originalText, {
+    context: 'greeting',
+    autoTranslate: true
+});
+
+// Manual translation update
+await updateTranslation('nl');
+</script>
+
+<template>
+    <div>
+        <span v-if="isLoading">Translating...</span>
+        <span v-else>{{ translatedText }}</span>
+    </div>
+</template>
+```
+
+## 🔄 Migration Guide

+    context: 'chat_message',    // Translation context
+    apiPrefix: '/chat-client',  // API prefix for tenant routing
+    fallbackText: 'Fallback'   // Fallback text on error
+};
+```
+
+### Error Handling
+
+```vue
+<script setup>
+import { useTranslation } from '@/composables';
+
+const { translate, lastError, isTranslating } = useTranslation();
+
+const handleTranslation = async () => {
+    try {
+        const result = await translate('Hello', 'nl');
+        console.log('Translation successful:', result);
+    } catch (error) {
+        console.error('Translation failed:', error);
+        // lastError.value will also contain the error
+    }
+};
+</script>
+```
+
+## 📈 Benefits Achieved
+
+1. **✅ Modern Vue 3 Patterns** - Composition API and reactive state
+2. **✅ Better Error Handling** - Comprehensive error states and fallbacks
+3. **✅ Loading States** - Built-in loading indicators
+4. **✅ Type Safety Ready** - Prepared for TypeScript integration
+5. **✅ Batch Operations** - Efficient multiple text translation
+6. **✅ Reactive Translation** - Automatic updates on language changes
+7. **✅ Backward Compatibility** - Gradual migration support
+
+## 🎉 Migration Status
+
+### ✅ Completed
+- Modern Vue 3 composables created
+- Barrel export updated
+- Documentation completed
+- Migration patterns established
+
+### 🔄 In Progress
+- ChatInput.vue migration
+- MessageHistory.vue migration
+
+### 📋 Next Steps
+- Complete component migrations
