Get all directories with nodejs 10+ fs.promises

getAllDirectories.js

const { lstat, readdir } = require('fs').promises;
const pFilter = require('p-filter'); // Promise filter although this can easily be replaced.

const isDirectory = async source => {
  const stats = await lstat(source);
  return stats.isDirectory();
};
const getDirectories = async source => {
  const list = await readdir(source);
  const resolvedList = list.map(name => join(source, name));
  return pFilter(resolvedList, isDirectory);
};
