Copy entire directories, safely. All work is done by pump and tar-fs. Thanks 2 mafintosh.
npm install --save pump-dir
var pumpDir = require('pump-dir')
pumpDir('./node_modules', 'clone_modules', function (err) {
if (err) return console.error(err)
console.log('cloned node_modules')
})Copy a directory. opts.ignore can be a predicate method by which all entries will be filtered. Must return true for files that shall be excluded, sig opts.ignore(name, headers), see tar-fs. Calling back like callback(err).
