closest-package experimental

Find the closest package.json file meeting specific criteria by searching upwards from a given directory until hitting root.



closest(dir, [filter], found(err, file))

Given a starting directory dir, look up through every directory to see if it contains a package.json file matching the filter function, for example:

closest(__dirname, function(json, filename) {
  return === 'async'
}, function(err, file) {

Note that filter is optional and takes the following arguments:

  • json: the parsed package.json file.
  • filename: the package.json's absolute filename.

file = closest.sync(dir, [filter])

Same as the closest function, however executed synchronously:

var result = closest.sync(__dirname, function(json, filename) {
  return === 'async'
