  const [prompt, setPrompt] = useState('')
  const [isGenerating, setIsGenerating] = useState(false)
  const [generatedLogos, setGeneratedLogos] = useState([])
  const generateLogo = async () => {
    if (!prompt.trim()) return
    setIsGenerating(true)
    try {
      // In production, this would call OpenAI API
      await new Promise(resolve => setTimeout(resolve, 2000))
      
      // Mock generated logos
      const mockLogos = [
        'https://via.placeholder.com/400x400/6366f1/ffffff?text=Logo+1',

            ))}
          
        
      )}
    
  )
}

Integrating AI APIs

1. OpenAI API Integration

// src/lib/openai.ts
import OpenAI from 'openai'
const openai = new OpenAI({
  apiKey: process.env.OPENAI_API_KEY,
})
export async function generateLogo(prompt: string) {
  try {
    const response = await openai.images.generate({
      model: "dall-e-3",
      prompt: Create a professional logo: ${prompt},
      n: 4,
      size: "1024x1024",
      quality: "standard",
    })
    
    return response.data.map(img => img.url).filter(Boolean)
  } catch (error) {
    console.error('Error generating logo:', error)
    throw new Error('Failed to generate logo')
  }
}
export async function generateColorPalette(mood: string) {
  try {
    const response = await openai.chat.completions.create({
      model: "gpt-4",
      messages: [
        {
          role: "system",
          content: "You are a color theory expert. Generate 5 complementary colors for the given mood or style. Return only hex codes separated by commas."
        },
        {
          role: "user",
          content: Generate a color palette for: ${mood}
        }
      ],
      max_tokens: 100,
    })
    
    const colors = response.choices[0].message.content?.split(',').map(c => c.trim()) || []
    return colors
  } catch (error) {
    console.error('Error generating color palette:', error)
    throw new Error('Failed to generate color palette')
  }
}

2. API Route for Logo Generation

// src/app/api/generate-logo/route.ts
import { NextRequest, NextResponse } from 'next/server'
import { generateLogo } from '@/lib/openai'
export async function POST(request: NextRequest) {
  try {
    const { prompt } = await request.json()
    
    if (!prompt) {
      return NextResponse.json(
        { error: 'Prompt is required' },
        { status: 400 }
      )
    }
    
    const logos = await generateLogo(prompt)
    
    return NextResponse.json({ logos })
  } catch (error) {
    console.error('Error in generate-logo API:', error)
    return NextResponse.json(
      { error: 'Failed to generate logo' },
      { status: 500 }
    )
  }
}

Adding Advanced Features

1. Color Palette Generator

// src/components/ColorPaletteGenerator.tsx
export default function ColorPaletteGenerator() {
  const [mood, setMood] = useState('')
  const [isGenerating, setIsGenerating] = useState(false)
  const [generatedPalettes, setGeneratedPalettes] = useState    id: string
    colors: string[]
    name: string
  }>>([])
  const generatePalette = async () => {
    if (!mood.trim()) return
    setIsGenerating(true)
    try {
      const response = await fetch('/api/generate-colors', {
        method: 'POST',
        headers: { 'Content-Type': 'application/json' },
        body: JSON.stringify({ mood })
      })
      
      const data = await response.json()
      setGeneratedPalettes(data.palettes)
    } catch (error) {
      console.error('Error generating palette:', error)
    } finally {
      setIsGenerating(false)
    }
  }
  const copyColor = (color: string) => {
    navigator.clipboard.writeText(color)
  }
  return (
    

      {/ Input and generation logic /}
      
        {/ Component implementation /}
      
    
  )
}

2. Design Suggestions Component

// src/components/DesignSuggestions.tsx
export default function DesignSuggestions() {
  const [selectedCategory, setSelectedCategory] = useState('trends')
  const [suggestions, setSuggestions] = useState([])
  const categories = [
    { id: 'trends', label: 'Design Trends', icon: TrendingUp },
    { id: 'colors', label: 'Color Theory', icon: Palette },
    { id: 'typography', label: 'Typography', icon: Type },
    { id: 'layout', label: 'Layout Tips', icon: Layout },
  ]
  const generateSuggestions = async (category: string) => {
    setSelectedCategory(category)
    
    try {
      const response = await fetch('/api/design-suggestions', {
        method: 'POST',
        headers: { 'Content-Type': 'application/json' },
        body: JSON.stringify({ category })
      })
      
      const data = await response.json()
      setSuggestions(data.suggestions)
    } catch (error) {
      console.error('Error generating suggestions:', error)
    }
  }
  return (
    

      {/ Category selection and suggestions display /}
    
  )
}

Styling with Glassmorphism

/ src/app/globals.css /
@tailwind base;
@tailwind components;
@tailwind utilities;
@layer components {
  .gradient-bg {
    background: linear-gradient(-45deg, #ee7752, #e73c7e, #23a6d5, #23d5ab);
    background-size: 400% 400%;
    animation: gradient 15s ease infinite;
  }
  
  .glass-morphism {
    @apply bg-white/10 backdrop-blur-md border border-white/20;
  }
  
  .card-hover {
    @apply transition-all duration-300 hover:scale-105 hover:shadow-xl;
  }
}
@keyframes gradient {
  0% { background-position: 0% 50%; }
  50% { background-position: 100% 50%; }
  100% { background-position: 0% 50%; }
}

Deployment

1. Environment Variables

.env.local
OPENAI_API_KEY=your_openai_api_key_here
NEXT_PUBLIC_APP_URL=https://your-domain.com

2. Vercel Deployment

Install Vercel CLI
npm i -g vercel
Deploy
vercel --prod

3. Vercel Configuration

// vercel.json
{
  "functions": {
    "src/app/api//*.ts": {
      "maxDuration": 30
    }
  },
  "env": {
    "OPENAI_API_KEY": "@openai_api_key"
  }
}

Best Practices

1. Error Handling

Always implement proper error handling for API calls:

try {
  const response = await fetch('/api/generate-logo', {
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify({ prompt })
  })
  
  if (!response.ok) {
    throw new Error('Failed to generate logo')
  }
  
  const data = await response.json()
  return data
} catch (error) {
  console.error('Error:', error)
  throw error
}

2. Loading States

Implement loading states for better UX:

const [isGenerating, setIsGenerating] = useState(false)
// In your component
{isGenerating ? (
  

    
    Generating...
  
) : (
  
    Generate Logo
  
)}

3. Type Safety

Use TypeScript interfaces for better type safety:

interface GeneratedLogo {
  id: string
  url: string
  prompt: string
  createdAt: Date
}
interface ColorPalette {
  id: string
  name: string
  colors: string[]
  mood: string
}

Performance Optimization

1. Image Optimization

import Image from 'next/image'
  src={logo.url}
  alt="Generated logo"
  width={400}
  height={400}
  className="object-cover"
  priority={index < 2} // Prioritize first two images
/>

2. Code Splitting

import dynamic from 'next/dynamic'
const LogoGenerator = dynamic(() => import('./LogoGenerator'), {
  loading: () => 
Loading...
})
