Apa itu React Framework?

React Framework adalah layer tambahan di atas React library yang menyediakan struktur, konvensi, dan fitur-fitur tambahan untuk membangun aplikasi web yang lebih kompleks dan production-ready.

Perbedaan React Library vs React Framework

React Library

React sendiri adalah library untuk membangun user interfaces, khususnya untuk:

  • Membuat komponen UI yang reusable
  • Mengelola state aplikasi
  • Handling events dan lifecycle
  • Virtual DOM untuk performa optimal

React Framework

React Framework menambahkan layer di atas React library dengan:

  • Routing system - Navigasi antar halaman
  • Build tools - Bundling, compilation, optimization
  • Server-side rendering - SEO dan performa
  • File conventions - Struktur proyek yang konsisten
  • Development tools - Hot reload, debugging
  • Production optimizations - Code splitting, caching

Mengapa Butuh React Framework?

1. Kompleksitas Setup

Membangun aplikasi React dari nol memerlukan konfigurasi yang kompleks:

// Manual setup yang diperlukan tanpa framework:
// - Webpack configuration
// - Babel setup
// - ESLint configuration  
// - Development server
// - Production build process
// - Code splitting
// - Asset optimization

2. Best Practices Built-in

Framework menyediakan best practices secara default:

  • File structure yang konsisten
  • Performance optimizations
  • Security considerations
  • SEO-friendly setup

3. Developer Experience

  • Hot module replacement
  • Error boundaries
  • Development tools
  • TypeScript support out-of-the-box

[[NextJS|Next.js]]

  • Full-stack framework dengan [[SSR]]/[[SSG]]
  • File-based routing dengan [[App Router]] dan [[Pages Router]]
  • API routes untuk backend functionality
  • Built-in optimizations (images, fonts, scripts)
  • Deployment terintegrasi dengan Vercel

Gatsby

  • Static site generator fokus pada performa
  • GraphQL data layer
  • Plugin ecosystem yang kaya
  • Progressive Web App features

Remix

  • Full-stack framework dengan fokus pada web standards
  • Nested routing
  • Data loading yang optimal
  • Progressive enhancement

Create React App (CRA)

  • Starter template untuk React applications
  • Zero configuration setup
  • Build scripts yang sudah dikonfigurasi
  • Testing setup included

Kapan Menggunakan Framework vs Library

Gunakan React Library Ketika:

  • Membangun komponen untuk aplikasi existing
  • Butuh kontrol penuh atas build process
  • Aplikasi sederhana dengan requirements khusus
  • Integrating React ke dalam aplikasi non-React

Gunakan React Framework Ketika:

  • Membangun aplikasi web lengkap
  • Butuh SEO optimization
  • Memerlukan server-side rendering
  • Tim development yang besar
  • Deadline yang ketat

Fitur Umum React Framework

1. Routing System

// File-based routing (Next.js style)
pages/
├── index.tsx          // Route: /
├── about.tsx          // Route: /about
├── blog/
   ├── index.tsx      // Route: /blog
   └── [slug].tsx     // Route: /blog/[slug]
└── api/
    └── users.ts       // API Route: /api/users

2. Data Fetching

// Server-side data fetching
export async function getServerSideProps() {
  const data = await fetch('https://api.example.com/data')
  return {
    props: { data }
  }
}

// Static generation
export async function getStaticProps() {
  const posts = await getPosts()
  return {
    props: { posts },
    revalidate: 60 // ISR - revalidate every 60 seconds
  }
}

3. Built-in Optimizations

// Image optimization
import Image from 'next/image'

function Gallery() {
  return (
    <Image
      src="/hero.jpg"
      alt="Hero"
      width={800}
      height={600}
      priority // Load immediately
      placeholder="blur" // Show blur while loading
    />
  )
}

// Font optimization
import { Inter } from 'next/font/google'

const inter = Inter({ subsets: ['latin'] })

export default function Layout({ children }) {
  return (
    <html className={inter.className}>
      <body>{children}</body>
    </html>
  )
}

4. Development Experience

// Hot module replacement
if (module.hot) {
  module.hot.accept()
}

// Error boundaries
function ErrorBoundary({ children }) {
  return (
    <ErrorBoundary
      fallback={<div>Something went wrong</div>}
      onError={(error) => console.log(error)}
    >
      {children}
    </ErrorBoundary>
  )
}

Memilih React Framework yang Tepat

Pertimbangan Utama

1. Jenis Aplikasi

  • Static sites → Gatsby, Next.js (SSG)
  • Dynamic apps → Next.js, Remix
  • E-commerce → Next.js dengan Shopify/Stripe
  • Blogs/CMS → Gatsby, Next.js

2. Performance Requirements

  • SEO critical → Next.js, Gatsby
  • Real-time apps → Next.js dengan WebSocket
  • Large datasets → Remix dengan optimized data loading

3. Team Expertise

  • React beginners → Create React App, Next.js
  • Full-stack developers → Next.js, Remix
  • Static site focus → Gatsby

4. Deployment Target

  • Vercel → Next.js (optimal)
  • Netlify → Gatsby, Next.js
  • Traditional hosting → Static export
  • Self-hosted → Any framework

Best Practices dengan React Framework

1. Project Structure

src/
├── components/        # Reusable UI components
│   ├── ui/           # Basic components (Button, Input)
│   └── features/     # Feature-specific components
├── pages/            # Route components
├── hooks/            # Custom React hooks
├── utils/            # Utility functions
├── styles/           # Global styles
└── types/            # TypeScript definitions

2. Performance Optimization

// Code splitting
const DynamicComponent = dynamic(() => import('./HeavyComponent'), {
  loading: () => <Spinner />,
  ssr: false
})

// Memoization
const ExpensiveComponent = memo(({ data }) => {
  const processedData = useMemo(() => 
    processLargeDataset(data), [data]
  )
  
  return <div>{processedData}</div>
})

3. State Management

// Context for global state
const AppContext = createContext()

// Custom hooks for state logic
function useAuth() {
  const [user, setUser] = useState(null)
  
  const login = useCallback(async (credentials) => {
    const user = await authenticate(credentials)
    setUser(user)
  }, [])
  
  return { user, login }
}

Migrasi dari Library ke Framework

Langkah Migrasi

1. Assessment

  • Evaluasi aplikasi existing
  • Identifikasi pain points
  • Tentukan target framework

2. Incremental Migration

// Gradual migration approach
// 1. Setup framework di folder baru
// 2. Migrate komponen satu per satu
// 3. Update routing secara bertahap
// 4. Migrate state management
// 5. Update build process

3. Testing Strategy

  • Unit tests untuk komponen
  • Integration tests untuk pages
  • E2E tests untuk user flows
  • Performance testing
