🔧 Technical Changes

1. Component Definition

Before (Vue 2):

Vue.component('tt-data-table', {
    data() {
        return { loading: false };
    },
    methods: {
        fetchData() { ... }
    }
});

After (Vue 3):

const TtDataTable = {
    name: 'TtDataTable',
    props: { ... },
    setup(props, { emit }) {
        const { ref } = Vue;
        const loading = ref(false);

        const fetchData = () => { ... };

        return { loading, fetchData };
    }
};

// Register on app instance
if (window.VueApp) {
    window.VueApp.component('tt-data-table', TtDataTable);
}

2. Lifecycle Hooks

Vue 2	Vue 3 Composition API
mounted()	onMounted(() => {})
beforeDestroy()	onBeforeUnmount(() => {})
destroyed()	onUnmounted(() => {})
updated()	onUpdated(() => {})

3. Reactivity System

Before (Vue 2):

data() {
    return {
        count: 0,
        user: { name: 'John' }
    };
}

After (Vue 3 Composition API):

setup() {
    const count = ref(0);
    const user = reactive({ name: 'John' });

    return { count, user };
}

4. v-model Changes

Vue 2:

• value prop + input event

Vue 3:

• modelValue prop + update:modelValue event

TT-Core Solution: All components support both automatically!

5. Composables

New in Vue 3:

// Use composables in setup()
const { data, isLoading, fetchData } = TT_CORE.useAsyncData();

// Composables return reactive refs
const { visibleItems, sentinelRef } = TT_CORE.useInfiniteScroll(items, {
    initialCount: 50
});

Backward Compatible:

// Mixins still work in Options API
export default {
    mixins: [TT_CORE.createAsyncDataMixin()]
}

8. <tt-view-switcher>

   • ✅ Vue 3 Composition API
   • ✅ v-model support (modelValue)
   • ✅ Computed property for currentView

🎨 Composables API

Three Modern Composables

1. useIntersectionObserver

const { targetRef } = TT_CORE.useIntersectionObserver((entry) => {
    console.log('Visible!', entry);
}, { threshold: 0.1 });

2. useInfiniteScroll

const items = ref([...1000 items]);
const {
    visibleItems,     // Computed - first N items
    sentinelRef,      // Template ref for observer
    hasMore,          // Boolean - more items available
    loadMore          // Function - load next batch
} = TT_CORE.useInfiniteScroll(items, {
    initialCount: 50,
    incrementBy: 25
});

3. useAsyncData

const {
    data,           // Ref - fetched data
    isLoading,      // Ref - loading state
    hasError,       // Ref - error state
    errorMessage,   // Ref - error message
    fetchData,      // Function - fetch from URL
    executeAsync,   // Function - execute any async fn
    reset           // Function - reset all state
} = TT_CORE.useAsyncData();

await fetchData('/api/users');

🔄 Migration Path

For Vue 2 Users

Option 1: Stay on Options API

// No changes needed! Mixins still work
export default {
    mixins: [TT_CORE.createInfiniteScrollMixin()],
    data() {
        return { users: [] };
    }
}

Option 2: Migrate to Composition API (Recommended)

<script setup>
import { ref } from 'vue';

const users = ref([]);
const { visibleItems } = TT_CORE.useInfiniteScroll(users);
</script>

For New Projects

Use Composition API from the start:

<!DOCTYPE html>
<html>
<head>
    <link rel="stylesheet" href="/public/plugins/vue/tt-core/styles/tt-core.css">
    <script src="https://unpkg.com/vue@3/dist/vue.global.js"></script>
</head>
<body>
    <div id="app">
        <tt-data-table :items="users">...</tt-data-table>
    </div>

    <script src="/public/plugins/vue/tt-core/index.js" type="module"></script>
    <script src="/public/plugins/vue/tt-core/components/data-display/TtDataTable.js"></script>

    <script>
        const { createApp, ref } = Vue;

        const app = createApp({
            setup() {
                const users = ref([...]);
                return { users };
            }
        });

        // CRITICAL: Register components
        TT_CORE.registerComponents(app);

        app.mount('#app');
    </script>
</body>
</html>

📊 Impact on Radius Module

Code Reduction (When Using TT-Core)

Before:

Radius.js:  1500 lines (utilities + components + page logic)
Radius.css: 275 lines (all styles)
Total:      1775 lines

After:

Radius.js:  ~100 lines (page logic only)
Radius.css: ~50 lines (page-specific only)
Total:      ~150 lines ⬇️ 92%

+ TT-Core:  ~2500 lines (reusable across ALL modules!)

Migration Checklist for Radius

• Replace new Vue() with createApp()
• Call TT_CORE.registerComponents(app)
• Replace window.RadiusUtils.* → window.TT_CORE.*
• Rename components:
  • radius-table-view → tt-data-table
  • radius-online-state → tt-status-chip
  • radius-file-drop → tt-file-dropzone
  • etc.
• Update v-model usage (automatic for TT-Core components)
• Remove duplicate utilities and components
• Test all functionality

🎁 Benefits of Vue 3 Upgrade

Performance

✨ Faster Initial Render - Composition API compiles better ✨ Better Tree-Shaking - Smaller bundle sizes ✨ Improved Reactivity - Proxy-based reactivity system ✨ Fragment Support - Multiple root elements in templates

Developer Experience

✨ Composition API - Better code organization ✨ TypeScript Support - Full type inference ✨ Better IDE Support - IntelliSense for refs ✨ Composable Logic - Reusable stateful logic

Features

✨ Teleport - Portal rendering (used in TtDialog) ✨ Suspense - Async component loading ✨ v-model Multiple - Multiple v-models per component ✨ Lifecycle Hooks - Can be called multiple times

🚀 Future Enhancements

Potential additions for v3.0:

• TypeScript definitions (.d.ts files)
• Provide/Inject patterns for deep component trees
• Suspense support for async components
• Form validation composable
• Toast notification system
• Advanced data grid with sorting/filtering
• Chart composables (bar, line, pie)

🎓 What We Learned

Vue 3 Best Practices

1. Composition API is powerful - Better code organization
2. Refs need .value - Access reactive values correctly
3. Lifecycle hooks are functions - onMounted() not mounted()
4. Multiple root elements - Fragments work automatically
5. v-model is modelValue - But backward compatible

Component Design

1. Reusability matters - Extract common patterns
2. Props > State - Make components controlled
3. Slots are flexible - Allow content customization
4. Emit events - Let parents handle logic
5. Document everything - JSDoc and README

Performance

1. Lazy load wisely - Intersection observers are great
2. Debounce inputs - Reduce API calls
3. Virtual scrolling - Infinite scroll for large lists
4. CSS variables - Fast theme updates
5. Module imports - Better tree-shaking
