import { GoogleGenAI } from '@google/genai';
import fs from 'fs';
import path from 'path';
import dotenv from 'dotenv';

// Load environment variables
dotenv.config();

const ai = new GoogleGenAI({});

async function generateAndSaveImage(prompt: string, outputPath: string, verbose: boolean = false): Promise<boolean> {
  try {
    if (verbose) {
      console.log(`🔍 VERBOSE: Starting image generation...`);
      console.log(`🔍 VERBOSE: Prompt: "${prompt}"`);
      console.log(`🔍 VERBOSE: Output path: ${outputPath}`);
    }

    console.log(`Generating image with prompt: "${prompt}"`);

    const response = await ai.models.generateContent({
      model: 'gemini-2.5-flash-image',
      contents: prompt,
    });

    if (verbose) {
      console.log(`🔍 VERBOSE: API response received`);
      console.log(`🔍 VERBOSE: Candidates count: ${response.candidates?.length || 0}`);
    }

    if (response.candidates && response.candidates.length > 0) {
      const candidate = response.candidates[0];

      if (candidate.content && candidate.content.parts) {
        for (const part of candidate.content.parts) {
          if (part.inlineData?.data) {
            const buffer = Buffer.from(part.inlineData.data, 'base64');

            // Ensure output directory exists
            const outputDir = path.dirname(outputPath);
            if (!fs.existsSync(outputDir)) {
              fs.mkdirSync(outputDir, { recursive: true });
            }

            fs.writeFileSync(outputPath, buffer);
            const fileSize = fs.statSync(outputPath).size;
            console.log(`✅ Image saved as ${outputPath} (${(fileSize / 1024 / 1024).toFixed(2)} MB)`);
            return true;
          }
        }
      }
    }

    console.log('⚠️ No image data found in response');
    return false;

    return false;
  }
}

// Usage example:
await generateAndSaveImage(
  'A serene Japanese garden with cherry blossoms',
  './output/japanese_garden.png',
  true // verbose mode
);

2. Image Editing with Error Handling

async function editImage(inputPath: string, prompt: string, outputPath: string): Promise<boolean> {
  try {
    // Validate input file exists
    if (!fs.existsSync(inputPath)) {
      console.error(`❌ Input image not found: ${inputPath}`);
      return false;
    }

    console.log(`Editing image: ${inputPath} with prompt: "${prompt}"`);

    // Read and convert image to base64
    const imageBuffer = fs.readFileSync(inputPath);
    const base64Image = imageBuffer.toString('base64');

    // Determine MIME type based on file extension
    const mimeType = path.extname(inputPath) === '.png' ? 'image/png' : 'image/jpeg';

    const response = await ai.models.generateContent({
      model: 'gemini-2.5-flash-image',
      contents: [
        {
          inlineData: {
            data: base64Image,
            mimeType: mimeType
          }
        },
        prompt
      ]
    });

    if (response.candidates && response.candidates.length > 0) {
      const candidate = response.candidates[0];
      if (candidate.content?.parts) {
        for (const part of candidate.content.parts) {
          if (part.inlineData?.data) {
            const buffer = Buffer.from(part.inlineData.data, 'base64');
            fs.writeFileSync(outputPath, buffer);
            console.log(`✅ Edited image saved as ${outputPath}`);
            return true;
          }
        }
      }
    }

    console.log('⚠️ No image data found in response');
    return false;
  } catch (error) {
    console.error('❌ Error editing image:', error);
    return false;
  }
}

// Usage example:
await editImage(
  './input/sunset.jpg',
  'Convert this to a night scene with stars',
  './output/night_sunset.jpg'
);

3. Batch Image Generation

interface ImageRequest {
  name: string;
  prompt: string;
  filename: string;
}

async function batchGenerateImages(requests: ImageRequest[], outputDir: string = './output'): Promise<void> {
  // Ensure output directory exists
  if (!fs.existsSync(outputDir)) {
    fs.mkdirSync(outputDir, { recursive: true });
  }

  console.log(`🎨 Starting batch generation of ${requests.length} images...`);

  let successCount = 0;
  let failureCount = 0;

  for (let i = 0; i < requests.length; i++) {
    const request = requests[i];
    console.log(`\n${i + 1}/${requests.length}: Generating ${request.name}...`);

    const outputPath = path.join(outputDir, request.filename);
    const success = await generateAndSaveImage(request.prompt, outputPath);

    if (success) {
      successCount++;
      console.log(`✅ Successfully generated ${request.name}`);
    } else {
      failureCount++;
      console.log(`❌ Failed to generate ${request.name}`);
    }

    // Add delay to respect rate limits
    if (i < requests.length - 1) {
      await new Promise(resolve => setTimeout(resolve, 1000));
    }
  }

  console.log(`\n📊 Batch generation completed:`);
  console.log(`✅ Successful: ${successCount}`);
  console.log(`❌ Failed: ${failureCount}`);
  console.log(`📁 Output directory: ${outputDir}`);
}

// Usage example:
const imageRequests: ImageRequest[] = [
  {
    name: 'Sunset Mountains',
    prompt: 'A beautiful sunset over mountains with vibrant colors and a serene lake',
    filename: 'sunset_mountains.png'
  },
  {
    name: 'Futuristic City',
    prompt: 'A futuristic cityscape at sunset with flying vehicles and neon lights',
    filename: 'futuristic_city.png'
  },
  {
    name: 'Japanese Garden',
    prompt: 'A serene Japanese garden with cherry blossoms and a koi pond',
    filename: 'japanese_garden.png'
  }
];

await batchGenerateImages(imageRequests);

4. Prompt File Management

async function generateFromPromptFile(promptFilePath: string, outputPath: string): Promise<boolean> {
  try {
    // Check if prompt file exists
    if (!fs.existsSync(promptFilePath)) {
      console.error(`❌ Prompt file not found: ${promptFilePath}`);
      return false;
    }

    // Read prompt from file
    const prompt = fs.readFileSync(promptFilePath, 'utf-8').trim();
    console.log(`📝 Read prompt from file: ${promptFilePath}`);
    console.log(`📝 Prompt content: "${prompt.substring(0, 100)}${prompt.length > 100 ? '...' : ''}"`);

    // Generate image
    return await generateAndSaveImage(prompt, outputPath, true);
  } catch (error) {
    console.error(`❌ Error reading prompt file: ${error}`);
    return false;
  }
}

// Create prompt file and generate
fs.writeFileSync('./prompts/garden.txt',
  'A serene Japanese garden with cherry blossoms in full bloom, a small koi pond, and traditional stone lanterns'
);

await generateFromPromptFile('./prompts/garden.txt', './output/garden.png');

5. Advanced Debugging and Logging

async function debugGenerateImage(prompt: string, outputPath: string): Promise<boolean> {
  console.log('🔍 DEBUG MODE: Starting image generation with detailed logging...');

  try {
    // Check API key
    if (!process.env.GEMINI_API_KEY) {

Best Practices

1. Crafting Effective Prompts

Be Specific: “A serene Japanese garden with cherry blossoms” works better than “garden”
Include Style: “in the style of impressionist painting” or “photorealistic”
Specify Lighting: “golden hour lighting” or “dramatic shadows”
Mention Composition: “wide angle shot” or “close-up macro”

2. Image Editing Tips

Use High-Quality Input: Better source images produce better results
Be Clear About Changes: “Make the sky blue” is clearer than “fix the sky”
Specify Output Format: Mention desired aspect ratios when needed

Image Editing Example

Here’s a real example of Nano Banana’s editing capabilities:

Original	Edited

Generated: “A beautiful sunset over mountains with vibrant colors”	Edited: “Convert this scene into a night scene with stars and a full moon”

This demonstrates how a single text prompt can completely transform an image’s atmosphere and lighting while preserving the core composition.

3. Error Handling

Always implement proper error handling for:

API rate limits
Safety policy violations
Network connectivity issues
Invalid API keys

Advanced Troubleshooting Guide

Common Issues and Solutions

1. API Authentication Problems

// Function to verify API key and connection
async function verifyApiKey(): Promise<boolean> {
  try {
    if (!process.env.GEMINI_API_KEY) {
      console.error('❌ GEMINI_API_KEY not found in environment variables');
      console.log('💡 Solution: Create a .env file with your API key:');
      console.log('   echo "GEMINI_API_KEY=your_api_key_here" > .env');
      return false;
    }

    // Test connection with a simple text request
    const testResponse = await ai.models.generateContent({
      model: 'gemini-2.0-flash-exp',
      contents: 'Respond with "API working" if you can read this.',
    });

    console.log(`✅ API key verified: ${testResponse.text}`);
    return true;
  } catch (error) {
    console.error('❌ API key verification failed:', error.message);
    return false;
  }
}

2. Handling Rate Limits

// Rate limit handling with exponential backoff
async function generateWithRetry(
  prompt: string,
  outputPath: string,
  maxRetries: number = 3
): Promise<boolean> {
  for (let attempt = 1; attempt <= maxRetries; attempt++) {
    try {
      console.log(`📝 Attempt ${attempt}/${maxRetries}`);
      const success = await generateAndSaveImage(prompt, outputPath, attempt > 1);
      if (success) return true;
    } catch (error) {
      if (error.message?.includes('quota') || error.message?.includes('rate')) {
        if (attempt === maxRetries) {
          console.error('❌ Max retries reached. Rate limit exceeded.');
          return false;
        }

        const delay = Math.pow(2, attempt) * 1000; // Exponential backoff
        console.log(`⏳ Rate limit hit. Waiting ${delay/1000} seconds...`);
        await new Promise(resolve => setTimeout(resolve, delay));
      } else {
        // Non-rate-limit error, don't retry
        console.error('❌ Non-retryable error:', error.message);
        return false;
      }
    }
  }
  return false;
}

3. Safety Policy Violation Detection

// Enhanced error detection for policy violations
function analyzeResponse(response: any): { success: boolean; issue?: string; suggestion?: string } {
  if (!response.candidates || response.candidates.length === 0) {
    return {
      success: false,
      issue: 'No candidates in response',
      suggestion: 'Your prompt may have been blocked by safety filters. Try rephrasing.'
    };
  }

  const candidate = response.candidates[0];

  if (candidate.finishReason === 'SAFETY') {
    return {
      success: false,
      issue: 'Content blocked by safety policy',
      suggestion: 'Remove potentially sensitive content or use different terminology.'
    };
  }

  if (candidate.finishReason === 'RECITATION') {
    return {
      success: false,
      issue: 'Content blocked for potential copyright violation',
      suggestion: 'Avoid referencing specific copyrighted material.'
    };
  }

  if (!candidate.content?.parts || candidate.content.parts.length === 0) {
    return {
      success: false,
      issue: 'No content parts in response',
      suggestion: 'The model may not have understood the prompt. Try simplifying.'
    };
  }

  return { success: true };
}

4. File System Error Handling

// Robust file operations with proper error handling
async function safeFileWrite(data: Buffer, filePath: string): Promise<boolean> {
  try {
    // Create directory if it doesn't exist
    const dir = path.dirname(filePath);
    if (!fs.existsSync(dir)) {
      console.log(`📁 Creating directory: ${dir}`);
      fs.mkdirSync(dir, { recursive: true });
    }

    // Check if file already exists
    if (fs.existsSync(filePath)) {
      const backupPath = `${filePath}.backup.${Date.now()}`;
      console.log(`⚠️ File exists, creating backup: ${backupPath}`);
      fs.copyFileSync(filePath, backupPath);
    }

    // Write file
    fs.writeFileSync(filePath, data);

    // Verify file was written correctly
    const stats = fs.statSync(filePath);
    if (stats.size === 0) {
      throw new Error('File was created but is empty');
    }

    console.log(`✅ File saved successfully: ${filePath} (${(stats.size / 1024).toFixed(1)} KB)`);
    return true;
  } catch (error) {
    console.error(`❌ File write error: ${error.message}`);

    if (error.code === 'EACCES') {
      console.log('💡 Solution: Check file permissions or run with appropriate privileges');
    } else if (error.code === 'ENOSPC') {
      console.log('💡 Solution: Free up disk space');
    } else if (error.code === 'ENOENT') {
      console.log('💡 Solution: Check if directory path is correct');
    }

    return false;
  }
}
