How to Build a Ai Image Generator

// Using OpenAI DALL-E API
async function generateImage(prompt, size = '1024x1024', style = 'vivid') {
  const response = await fetch('https://api.openai.com/v1/images/generations', {
    method: 'POST',
    headers: {
      'Authorization': `Bearer ${process.env.OPENAI_API_KEY}`,
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({
      model: 'dall-e-3',
      prompt: prompt,
      n: 1,
      size: size,
      style: style // 'vivid' or 'natural'
    })
  });

  const data = await response.json();
  return data.data[0].url;
}

// Prompt enhancement for better results
function enhancePrompt(basePrompt, style, quality) {
  const styleModifiers = {
    photorealistic: 'photorealistic, 8k, highly detailed',
    artistic: 'digital art, trending on artstation',
    minimal: 'minimalist, clean, simple'
  };
  return `${basePrompt}, ${styleModifiers[style]}, ${quality}`;
}
