Remove empty folders from directory-tree

gistfile1.txt

const dirTree = require('directory-tree')

const removeEmptyFolder = (obj, parent) => {
  const { children, name } = obj
  if (children) {
    let i = children.length
    while (i--) {
      const child = children[i]
      removeEmptyFolder(child, obj)
    }

    if (children.length === 0) {
      const index = parent.children.findIndex((child) => child.name === name)
      parent.children.splice(index, 1)
    }
  }
}

const data = dirTree('{your_folder_path}')
removeEmptyFolder(data)

Thanks for this snippet !
Line 12 should be if (children.length === 0 && parent) to handle the (corner) case where the first path given to the function is itself an empty folder. Otherwise it'll throw a TypeError: Cannot read property 'children' of undefined error.
