Node.js एप्लिकेशन में कई दस्तावेज़ों को PDF फ़ाइलों में कैसे बदलें?

const { processFolder } = require('files2pdf');
const path = require('path');
const fs = require('fs').promises;

async function convertDocuments(inputPath, outputPath) {
  try {
    // Verify input folder exists
    await fs.access(inputPath);
    
    console.log(`Starting conversion process...`);
    console.log(`Input folder: ${inputPath}`);
    console.log(`Output folder: ${outputPath}`);
    
    // Process all files in the folder
    await processFolder(inputPath, outputPath);
    
    console.log('Conversion completed successfully!');
    return { success: true, message: 'All documents converted' };
  } catch (error) {
    console.error('Conversion failed:', error.message);
    return { success: false, error: error.message };
  }
}

// Usage example
const inputDir = path.resolve(__dirname, 'documents');
const outputDir = path.resolve(__dirname, 'pdfs');

convertDocuments(inputDir, outputDir)
  .then(result => {
    if (result.success) {
      console.log('Success:', result.message);
    } else {
      console.log('Failed:', result.error);
    }
  });

Node.js में किसी डायरेक्टरी में लोड की गई नई फ़ाइलों को बदलने के लिए फ़ाइल मॉनिटरिंग सिस्टम कैसे बनाएं?

const { processFolder } = require('files2pdf');
const chokidar = require('chokidar');
const path = require('path');
const fs = require('fs').promises;

class DocumentConverter {
  constructor(watchDir, outputDir) {
    this.watchDir = path.resolve(watchDir);
    this.outputDir = path.resolve(outputDir);
    this.processing = new Set();
  }

  async initialize() {
    // Ensure output directory exists
    await fs.mkdir(this.outputDir, { recursive: true });
    
    // Set up file watcher
    const watcher = chokidar.watch(this.watchDir, {
      ignored: /(^|[\/\\])\../, // ignore dotfiles
      persistent: true,
      ignoreInitial: false
    });

    watcher.on('add', async (filePath) => {
      await this.handleNewFile(filePath);
    });

    console.log(`Watching ${this.watchDir} for new documents...`);
  }

  async handleNewFile(filePath) {
    const ext = path.extname(filePath).toLowerCase();
    const supportedFormats = ['.ppt', '.pptx', '.doc', '.docx'];

    if (!supportedFormats.includes(ext)) {
      return; // Skip unsupported files
    }

    if (this.processing.has(filePath)) {
      return; // Already processing this file
    }

    this.processing.add(filePath);
    console.log(`New file detected: ${path.basename(filePath)}`);

    try {
      await processFolder(path.dirname(filePath), this.outputDir);
      console.log(`Successfully converted: ${path.basename(filePath)}`);
    } catch (error) {
      console.error(`Error converting ${path.basename(filePath)}:`, error.message);
    } finally {
      this.processing.delete(filePath);
    }
  }
}

// Initialize the converter
const converter = new DocumentConverter('./watched-folder', './converted-pdfs');
converter.initialize();
