opreator.remove(from, names)
opreator.extract(from, to)
operator.zip(from, to)
operator.tar(from, to)
const prefix = '/fileop';
const operator = await fileop({
prefix,
});
const from = '/';
const to = '/tmp';
const names = [
'bin',
];
const progress = (value) => {
console.log('progress:', value);
};
const end = (op) => () => {
console.log('end');
op.removelistener('progress', progress);
op.removelistener('end', end);
};
const error = (op) => (data) => {
const msg = data + '\n continue?';
const is = confirm(msg);
if (is)
return op.continue();
op.abort();
};
operator.copy(from, to, names).then((op) => {
op.on('progress', progress);
op.on('end', end(op));
op.on('error', error(op));
});
