Think cp -r
, but pure node, and asynchronous. ncp
can be used both as a CLI tool and programmatically.
Usage is simple: ncp [source] [dest] [--limit=concurrency limit] [--filter=filter]
The 'filter' is a Regular Expression - matched files will be copied.
The 'concurrency limit' is an integer that represents how many pending file system requests ncp
has at a time.
If there are no errors, ncp
will output done.
when complete. If there are errors, the error messages will be logged to stdout
and to ./ncp-debug.log
, and the copy operation will attempt to continue.
Programmatic usage of ncp
is just as simple. The only argument to the completion callback is a possible error.
var ncp = require('ncp').ncp;
ncp.limit = 16;
ncp(source, destination, function (err) {
if (err) {
return console.error(err);
}
console.log('done!');
});
You can also call ncp like ncp(source, destination, options, callback)
.
options
should be a dictionary. Currently, such options are available:
options.filter
- aRegExp
instance, against which each file name is tested to determine whether to copy it or not, or a function taking single parameter: copied file name, returningtrue
orfalse
, determining whether to copy file or not.
