⚡ React 19: The Evolution Continues

🔥 Fitur Baru yang Game-Changing

1. React Compiler (Automatic Optimization)

React 19 hadir dengan compiler otomatis yang mengoptimasi kode lo tanpa perlu manual memoization.

// Sebelumnya (React 18)
const ExpensiveComponent = memo(({ data, filter }) => {
  const filteredData = useMemo(() => 
    data.filter(item => item.category === filter), 
    [data, filter]
  );

  return (
    <div>
      {filteredData.map(item => (
        <Item key={item.id} data={item} />
      ))}
    </div>
  );
});

// Sekarang (React 19) - Compiler handles optimization automatically
const ExpensiveComponent = ({ data, filter }) => {
  const filteredData = data.filter(item => item.category === filter);

  return (
    <div>
      {filteredData.map(item => (
        <Item key={item.id} data={item} />
      ))}
    </div>
  );
};

Benefit: Nggak perlu lagi pusing sama useMemo, useCallback, dan memo. Compiler otomatis optimize!

2. Server Components Evolution

Server Components di React 19 udah jauh lebih mature dan mudah digunakan.

// Server Component - runs on server
async function BlogPost({ slug }) {
  // This runs on the server
  const post = await fetchPost(slug);
  
  return (
    <article>
      <h1>{post.title}</h1>
      <div dangerouslySetInnerHTML={{ __html: post.content }} />
      <CommentSection postId={post.id} /> {/* Client Component */}
    </article>
  );
}

// Client Component - runs on browser
'use client';
function CommentSection({ postId }) {
  const [comments, setComments] = useState([]);
  
  // Client-side logic here
  return <div>{/* Interactive comments */}</div>;
}

3. Actions dan Form Handling

React 19 introduce Actions yang bikin form handling jadi super clean.

function ContactForm() {
  async function submitForm(formData) {
    'use server'; // Server Action
    
    const result = await sendEmail({
      name: formData.get('name'),
      email: formData.get('email'),
      message: formData.get('message')
    });
    
    if (result.success) {
      redirect('/thank-you');
    }
  }

  return (
    <form action={submitForm}>
      <input name="name" required />
      <input name="email" type="email" required />
      <textarea name="message" required />
      <button type="submit">Send Message</button>
    </form>
  );
}

4. use() Hook - Data Fetching Revolution

Hook baru yang bikin data fetching jadi lebih intuitif.

function UserProfile({ userId }) {
  // use() can handle promises directly
  const user = use(fetchUser(userId));
  const posts = use(fetchUserPosts(userId));

  return (
    <div>
      <h1>{user.name}</h1>
      <p>{user.bio}</p>
      <PostList posts={posts} />
    </div>
  );
}

// With Suspense boundary
function App() {
  return (
    <Suspense fallback={<Loading />}>
      <UserProfile userId="123" />
    </Suspense>
  );
}

🌟 Vue 4: The Composition Revolution

🔥 Fitur Baru yang Bikin Developer Happy

1. Vapor Mode - Compilation Strategy

Vue 4 introduce Vapor Mode yang compile component jadi vanilla JavaScript super optimized.

<!-- Traditional Vue -->
<template>
  <div class="counter">
    <h2>{{ title }}</h2>
    <p>Count: {{ count }}</p>
    <button @click="increment">+</button>
  </div>
</template>

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

const title = 'My Counter'
const count = ref(0)

const increment = () => {
  count.value++
}
</script>

Dengan Vapor Mode, ini di-compile jadi JavaScript yang super efficient tanpa virtual DOM overhead.

2. Enhanced TypeScript Integration

Vue 4 punya TypeScript support yang jauh lebih baik dengan type inference yang powerful.

<script setup lang="ts">
interface User {
  id: number
  name: string
  email: string
}

// Type inference works perfectly
const users = ref<User[]>([])
const selectedUser = computed(() => 
  users.value.find(user => user.id === selectedId.value)
)

// Props with perfect TypeScript support
interface Props {
  userId: number
  showEmail?: boolean
}

const props = withDefaults(defineProps<Props>(), {
  showEmail: true
})

// Emits with type safety
const emit = defineEmits<{
  userSelected: [user: User]
  emailToggled: [show: boolean]
}>()
</script>

3. Suspense dan Async Components

Vue 4 bikin async component handling jadi lebih smooth.

<template>
  <Suspense>
    <template #default>
      <AsyncUserProfile :user-id="userId" />
      <AsyncUserPosts :user-id="userId" />
    </template>
    
    <template #fallback>
      <div class="loading">
        <Spinner />
        <p>Loading user data...</p>
      </div>
    </template>
  </Suspense>
</template>

<script setup>
// AsyncUserProfile.vue
const props = defineProps<{ userId: number }>()

// This automatically works with Suspense
const user = await $fetch(`/api/users/${props.userId}`)
const posts = await $fetch(`/api/users/${props.userId}/posts`)
</script>

4. Reactivity Transform (Experimental)

Fitur eksperimental yang bikin reactive programming jadi lebih natural.

<script setup>
// Traditional
const count = ref(0)
const doubled = computed(() => count.value * 2)

// With Reactivity Transform
let count = $ref(0)
let doubled = $computed(() => count * 2)

// No more .value!
function increment() {
  count++ // Instead of count.value++
}
</script>

📊 Performance Showdown

Bundle Size Comparison

# React 19 (production build)
react + react-dom: ~45KB gzipped

# Vue 4 (production build)  
vue: ~38KB gzipped

Runtime Performance

React 19:

• Server Components reduce client-side JavaScript
• Automatic optimization via compiler
• Better hydration performance

Vue 4:

• Vapor Mode eliminates virtual DOM overhead
• Smaller runtime footprint
• Faster initial render

Memory Usage

// React 19 - Memory efficient with compiler optimizations
function TodoList({ todos }) {
  // Compiler automatically optimizes this
  return todos.map(todo => <TodoItem key={todo.id} todo={todo} />)
}

// Vue 4 - Vapor Mode uses minimal memory
<template>
  <div v-for="todo in todos" :key="todo.id">
    <TodoItem :todo="todo" />
  </div>
</template>

🚀 Migration Guide

Dari React 18 ke React 19

// Before (React 18)
function App() {
  const [data, setData] = useState(null)
  
  useEffect(() => {
    fetchData().then(setData)
  }, [])
  
  if (!data) return <Loading />
  
  return <DataDisplay data={data} />
}

// After (React 19)
function App() {
  const data = use(fetchData()) // Much cleaner!
  
  return <DataDisplay data={data} />
}

// Wrap with Suspense
function Root() {
  return (
    <Suspense fallback={<Loading />}>
      <App />
    </Suspense>
  )
}

Dari Vue 3 ke Vue 4

<!-- Vue 3 -->
<script setup>
import { ref, computed } from 'vue'

const count = ref(0)
const doubled = computed(() => count.value * 2)

function increment() {
  count.value++
}
</script>

<!-- Vue 4 (with Reactivity Transform) -->
<script setup>
let count = $ref(0)
let doubled = $computed(() => count * 2)

function increment() {
  count++ // No more .value!
}
</script>

✍️ Kesimpulan

Nggak ada framework yang “terbaik” secara absolut. Yang ada adalah framework yang paling cocok untuk kebutuhan lo.

React 19 cocok kalau lo:

• Pengen skill yang marketable
• Suka ecosystem yang besar
• Nggak masalah sama learning curve

Vue 4 cocok kalau lo:

• Prioritas development speed
• Suka syntax yang clean
• Pengen framework yang “just works”

Yang penting, master satu framework dulu sebelum loncat ke yang lain. Deep knowledge di satu framework lebih valuable daripada surface knowledge di banyak framework.
