Installation

API

const listEmptyFiles = require('list-empty-files');

listEmptyFiles(dir)

dir: string (directory path)
options: Object (readdir-sorted options)
Return: Promise<Set<string>>

The promise will be fulfilled with a Set of strings — absolute paths of all zero byte files included in the given directory.

Options are directly passed to the underlying readdir-sorted to control the order of results.

listEmptyFiles('/empty-files').then(files => {
  const iterator = files.keys();

  iterator.next().value; //=> '/empty-files/10.js'
  iterator.next().value; //=> '/empty-files/2a.js'
  iterator.next().value; //=> '/empty-files/2A.js'
});

listEmptyFiles('/dir', {
  numeric: true,
  caseFirst: 'upper'
}).then(files => {
  const iterator = files.keys();

  iterator.next().value; //=> '/empty-files/2A.js'
  iterator.next().value; //=> '/empty-files/2a.js'
  iterator.next().value; //=> '/empty-files/10.js'
});
