Package Exports

empty-dir
empty-dir/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (empty-dir) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

empty-dir

Check if a directory is empty.

Usage

var emptyDir = require('empty-dir');

// Using an error-back
emptyDir('./', function (err, result) {
  if (err) {
    console.error(err);
  } else {
    console.log('Directory is empty:', result);
  }
});

// Using a Promise
emptyDir('./').then(function (result) {
  console.log('Directory is empty:', result);
});

var result = emptyDir.sync('./test/empty');
console.log('Directory is empty:', result);

API

`emptyDir(paths, [filterFunction], [callback])`

Takes a path string or array of path strings and returns a Promise. Checks if the given paths are empty and resolves with a boolean indicating if the paths are empty directories. Optionally takes a filter function to filter out files that cause false positives. Also, can take a node-style callback function instead of returning a Promise.

`emptyDir.sync(paths, [filterFunction])`

Same as the above API but operates and returns synchronously. An error will be thrown.

Filter function

Both async and sync take a filter function as the second argument, to ignore files like .DS_Store on mac or Thumbs.db on windows from causing false-negatives.

var emptyDir = require('empty-dir');

function filter(filepath) {
  return /(Thumbs\.db|\.DS_Store)$/i.test(filepath);
}

emptyDir('./', filter, function (err, isEmpty) {
  if (err) {
    console.error(err);
  } else {
    console.log('Directory is empty:', isEmpty);
  }
});

var isEmpty = emptyDir.sync('./test/empty', filter);
console.log('Directory is empty:', isEmpty);

Promises

Global promises are required for this module. If you are using a platform that doesn't have promise support, you'll need to polyfill Promise on the global.

global.Promise = require('insert-your-promise-polyfill-here');

var emptyDir = require('empty-dir');

emptyDir('./').then(function (result) {
  console.log('Directory is empty:', result);
});
