import TurboDownloader from 'turbo-downloader';
const downloader = new TurboDownloader({
url: 'https://example.com/my_file',
destFile: '/some/path/to/save',
chunkSize: 16 * 1024 * 1024, // Size of chunk (default 16MB)
concurrency: 8, // Number of connections (default 4)
retryCount: 10, // Number of downloading retries of each chunk (default 10)
canBeResumed: true, // If true, you can resume download next time if current download failed (downloader save .turbodownload file near destination file)
transformStream: (stream: stream.Readable) => stream.Readable // Transform input data (decrypt, for example)
});
downloader
.download((downloaded, total) =>{
console.log(`Downloaded ${downloaded} of ${total}`);
})
