The file extensions for gzip and deflate do not match the requirements. According to the task description, the extensions should be .gz for gzip and .dfl for deflate.

It looks like the file extensions for gzip and deflate haven't been updated yet from the previous review. According to the task description, they should be .gz and .dfl respectively.

const compressedFileName = `${fileName}${extensions[compressionType]}`;

res.statusCode = 200;
res.setHeader('Content-Type', 'application/octet-stream');

res.setHeader(
'Content-Disposition',
`attachment; filename=${compressedFileName}`,
);

const { Readable } = require('stream');

Readable.from(fileBuffer).pipe(compressor).pipe(res);
});

req.pipe(busboy);

return;
}

res.statusCode = 404;
res.end('Not found');
});
}
