Immediately closes all active daemon processes and clears the daemon pool. This is useful for manual cleanup or when shutting down your application.

​
Syntax

OpenComicAI.closeAllDaemons(): void

​
Parameters

This method takes no parameters.

​
Returns

void - This method does not return a value.

​
Behavior

  • Closes all active daemon processes immediately
  • Clears the internal daemon pool completely
  • Does not wait for ongoing operations to complete
  • Frees all memory used by daemon processes
  • Safe to call even if no daemons are running

​
Example

import OpenComicAI from '@opencomic/ai-bin';

// Process multiple images with daemon mode
for (const image of images) {
  await OpenComicAI.upscale({
    input: image,
    output: `upscaled-${image}`,
    daemonMode: true
  });
}

// Clean up all daemons when done
OpenComicAI.closeAllDaemons();

​
Use cases

​
Application shutdown

process.on('SIGINT', () => {
  console.log('Shutting down...');
  OpenComicAI.closeAllDaemons();
  process.exit(0);
});

​
After batch processing

async function processBatch(images) {
  try {
    for (const image of images) {
      await OpenComicAI.upscale({
        input: image,
        output: `upscaled-${image}`,
        daemonMode: true
      });
    }
  } finally {
    // Ensure cleanup even if errors occur
    OpenComicAI.closeAllDaemons();
  }
}

​
Memory management

// Process large batches with periodic cleanup
for (let i = 0; i < largeImageArray.length; i++) {
  await OpenComicAI.upscale({
    input: largeImageArray[i],
    output: `upscaled-${i}.jpg`,
    daemonMode: true
  });
  
  // Close daemons every 100 images to manage memory
  if (i % 100 === 0) {
    OpenComicAI.closeAllDaemons();
  }
}

​
Important notes

  • Does not interrupt currently processing images
  • Daemons will be recreated automatically on next upscale operation
  • Use this for explicit cleanup; daemons also close automatically based on idle timeout
