Usage

Here's a basic example of how to use Prometeo to download a file:

  connections: 4, // Number of concurrent download connections (optional)
  tempdir: '/path/to/temp/folder', // Temporary storage directory (optional)
  userAgent: 'Your User Agent', // User agent for HTTP requests (optional)
  speedLimit: 10, // Speed limit in Mbps (optional)
});

// Start a download
const download = prometeo.download({
  url: 'https://example.com/largefile.zip',
  path: '/path/to/save/',
  filename: 'save.zip' //(optional)
});

download.on('start', () => {
  console.log('Download started');
});

download.on('progress', ({speed, progress, estimated}) => {
  console.log(`Download progress: ${progress}% with a speed of ${speed} (estimated: ${estimated / 1000} seconds)`);
});

download.on('finish', () => {
  console.log('Download finished');
});

setTimeout(() => {
    prometeo.setSpeed(5)
}, 5000) //Change the limit speed to 5 Mbps before 5 seconds

let filePath = await download.start();
console.log(`file saved at: ${filePath}`)
