// to handle `onFinish` event pass an additional callback
tgz_modify('files/package.tgz', 'output/package.tgz', (h, d) => d, (err) => {})
// or just await a promise
await tgz_modify('files/package.tgz', 'output/package.tgz', ...)To overwrite the .tgz file, simply use the same filename for the output file:
