Introducción

¿Qué es Turbopack?

Turbopack es un empaquetador incremental optimizado para JavaScript y TypeScript, escrito en Rust por los creadores de Webpack y Next.js. Representa un cambio fundamental en cómo funcionan los empaquetadores, enfocándose en el cómputo incremental para lograr una velocidad sin precedentes.

Características Principales

• Cómputo Incremental: Solo procesa lo que ha cambiado
• Rendimiento de Rust: Construido en Rust para máxima velocidad
• Reemplazo de Módulos en Caliente: Actualizaciones instantáneas durante el desarrollo
• Independiente de Framework: Funciona con cualquier framework de JavaScript
• Integración con Next.js: Soporte de primera clase para aplicaciones Next.js
• Soporte Nativo de TypeScript: Soporte integrado de TypeScript sin configuración

```### Configuración de TypeScript
```typescript
// hooks/useApi.ts
import { useState, useEffect } from 'react'
import { ApiResponse } from '@/types'

interface UseApiOptions {
  immediate?: boolean
}

export function useApi<T>(
  url: string, 
  options: UseApiOptions = {}
) {
  const [data, setData] = useState<T | null>(null)
  const [loading, setLoading] = useState(false)
  const [error, setError] = useState<string | null>(null)

  const fetchData = async () => {
    setLoading(true)
    setError(null)
    
    try {
      const response = await fetch(url)
      const result: ApiResponse<T> = await response.json()
      
      if (result.status === 'success') {
        setData(result.data)
      } else {
        setError(result.message)
      }
    } catch (err) {
      setError(err instanceof Error ? err.message : 'An error occurred')
    } finally {
      setLoading(false)
    }
  }

  useEffect(() => {
    if (options.immediate !== false) {
      fetchData()
    }
  }, [url])

  return { data, loading, error, refetch: fetchData }
}
```### Definiciones de Tipos
```bash
# .env.local
NEXT_PUBLIC_API_URL=http://localhost:3001/api
NEXT_PUBLIC_APP_NAME=Turbopack App
DATABASE_URL=postgresql://user:password@localhost:5432/mydb
SECRET_KEY=your-secret-key

# .env.production
NEXT_PUBLIC_API_URL=https://api.production.com
NEXT_PUBLIC_APP_NAME=Production App
DATABASE_URL=postgresql://user:password@prod-db:5432/mydb
SECRET_KEY=production-secret-key
```### Componentes Tipados
```typescript
// lib/config.ts
export const config = {
  apiUrl: process.env.NEXT_PUBLIC_API_URL || 'http://localhost:3001/api',
  appName: process.env.NEXT_PUBLIC_APP_NAME || 'My App',
  isDevelopment: process.env.NODE_ENV === 'development',
  isProduction: process.env.NODE_ENV === 'production',
}

// Server-side only
export const serverConfig = {
  databaseUrl: process.env.DATABASE_URL!,
  secretKey: process.env.SECRET_KEY!,
}

// components/ApiExample.tsx
'use client'

import { config } from '@/lib/config'
import { useEffect, useState } from 'react'

export default function ApiExample() {
  const [data, setData] = useState(null)

  useEffect(() => {
    fetch(`${config.apiUrl}/hello`)
      .then(res => res.json())
      .then(setData)
  }, [])

  return (
    <div className="p-4 border rounded-lg">
      <h3 className="font-semibold mb-2">API Response</h3>
      <p className="text-sm text-gray-600 mb-2">
        API URL: {config.apiUrl}
      </p>
      <pre className="text-xs bg-gray-100 p-2 rounded">
        {JSON.stringify(data, null, 2)}
      </pre>
    </div>
  )
}
```### Hooks Personalizados con TypeScript
```javascript
// next.config.js
const nextConfig = {
  env: {
    CUSTOM_KEY: process.env.CUSTOM_KEY,
    BUILD_TIME: new Date().toISOString(),
  },
  
  publicRuntimeConfig: {
    // Available on both server and client
    apiUrl: process.env.API_URL,
  },
  
  serverRuntimeConfig: {
    // Only available on server
    secretKey: process.env.SECRET_KEY,
  },
}

module.exports = nextConfig
```## Plugins
```javascript
// next.config.js
const nextConfig = {
  experimental: {
    turbo: {
      // Loader configuration (limited plugin support)
      loaders: {
        '.svg': ['@svgr/webpack'],
        '.md': ['raw-loader'],
        '.graphql': ['graphql-tag/loader'],
      },
      
      // Rules for file processing
      rules: {
        '*.svg': {
          loaders: ['@svgr/webpack'],
          as: '*.js',
        },
      },
    },
  },
}
```### Webpack Plugins (Fallback)
```javascript
// next.config.js
const nextConfig = {
  webpack: (config, { buildId, dev, isServer, defaultLoaders, webpack }) => {
    // Custom webpack configuration for features not yet supported in Turbopack
    config.plugins.push(
      new webpack.DefinePlugin({
        __BUILD_ID__: JSON.stringify(buildId),
      })
    )

    return config
  },
  
  experimental: {
    turbo: {
      // Turbopack configuration
    },
  },
}
```### Future Plugin System
```javascript
// Future Turbopack plugin API (conceptual)
const nextConfig = {
  experimental: {
    turbo: {
      plugins: [
        // Future plugin system
        '@turbopack/plugin-sass',
        '@turbopack/plugin-postcss',
        ['@turbopack/plugin-custom', { options: {} }],
      ],
    },
  },
}
```## Performance
```bash
# Development server startup
Turbopack: ~1.8s (10x faster than Vite)
Vite: ~11.4s
Webpack: ~16.5s

# Hot Module Replacement
Turbopack: ~6ms (5x faster than Vite)
Vite: ~30ms
Webpack: ~612ms (100x slower)

# Large codebase (30k modules)
Turbopack: ~1.2s startup
Webpack: ~30s startup
```### Performance Benchmarks
```tsx
// components/PerformanceMonitor.tsx
'use client'

import { useEffect, useState } from 'react'

export default function PerformanceMonitor() {
  const [metrics, setMetrics] = useState<any>(null)

  useEffect(() => {
    if (typeof window !== 'undefined' && 'performance' in window) {
      const navigation = performance.getEntriesByType('navigation')[0] as PerformanceNavigationTiming
      
      setMetrics({
        domContentLoaded: navigation.domContentLoadedEventEnd - navigation.domContentLoadedEventStart,
        loadComplete: navigation.loadEventEnd - navigation.loadEventStart,
        firstPaint: performance.getEntriesByName('first-paint')[0]?.startTime,
        firstContentfulPaint: performance.getEntriesByName('first-contentful-paint')[0]?.startTime,
      })
    }
  }, [])

  if (!metrics) return null

  return (
    <div className="p-4 bg-gray-100 rounded-lg">
      <h3 className="font-semibold mb-2">Performance Metrics</h3>
      <div className="grid grid-cols-2 gap-2 text-sm">
        <div>DOM Content Loaded: {metrics.domContentLoaded?.toFixed(2)}ms</div>
        <div>Load Complete: {metrics.loadComplete?.toFixed(2)}ms</div>
        <div>First Paint: {metrics.firstPaint?.toFixed(2)}ms</div>
        <div>First Contentful Paint: {metrics.firstContentfulPaint?.toFixed(2)}ms</div>
      </div>
    </div>
  )
}
```### Performance Monitoring
```bash
# Install bundle analyzer
npm install --save-dev @next/bundle-analyzer

# Analyze bundle
ANALYZE=true npm run build

// next.config.js
const withBundleAnalyzer = require('@next/bundle-analyzer')({
  enabled: process.env.ANALYZE === 'true',
})

const nextConfig = {
  experimental: {
    turbo: {
      // Turbopack configuration
    },
  },
}

module.exports = withBundleAnalyzer(nextConfig)
```### Bundle Analysis
```bash
# Update Next.js to latest version
npm install next@latest

# Update package.json scripts
{
  "scripts": {
    "dev": "next dev --turbo",
    "build": "next build",
    "start": "next start"
  }
}
```## Migration
`--turbo`### From Webpack to Turbopack
```javascript
// Issue: Custom webpack loaders not supported
// Solution: Use Turbopack loader configuration
const nextConfig = {
  experimental: {
    turbo: {
      loaders: {
        '.custom': ['custom-loader'],
      },
    },
  },
  
  // Fallback to webpack for unsupported features
  webpack: (config) => {
    // Custom webpack configuration
    return config
  },
}
```### Migration Checklist
- [ ] Actualizar Next.js a la versión 13.5+
- [ ] Agregar la bandera ```javascript
// next.config.js
const nextConfig = {
  experimental: {
    turbo: {
      // Enable Turbopack for development only
    },
  },
  
  // Keep webpack configuration for production builds
  webpack: (config, { dev }) => {
    if (!dev) {
      // Production webpack configuration
    }
    return config
  },
}
```al script de desarrollo
- [ ] Probar todas las funciones en desarrollo
- [ ] Actualizar configuración personalizada de webpack
- [ ] Verificar que todos los loaders funcionen correctamente
- [ ] Probar reemplazo de módulo en caliente
- [ ] Verificar compatibilidad del proceso de compilación
```bash
# Check Next.js version
npx next --version

# Ensure version 13.5+
npm install next@latest

# Clear cache
rm -rf .next
npm run dev -- --turbo
```### Common Migration Issues
```javascript
// next.config.js
const nextConfig = {
  experimental: {
    turbo: {
      resolveAlias: {
        '@': './src',
        '@components': './src/components',
      },
      resolveExtensions: ['.tsx', '.ts', '.jsx', '.js'],
    },
  },
}
```### Gradual Migration
```bash
# Check file watching limits (Linux)
echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf
sudo sysctl -p

# Restart development server
npm run dev -- --turbo
```## Troubleshooting
```bash
# Enable verbose logging
DEBUG=turbopack* npm run dev -- --turbo

# Check for unsupported features
npm run build
```### Common Issues
```javascript
// next.config.js
const nextConfig = {
  experimental: {
    turbo: {
      // Enable debug mode
      logLevel: 'debug',
      
      // Memory limit
      memoryLimit: 4096,
    },
  },
  
  // Enable source maps
  productionBrowserSourceMaps: true,
}
