ToFileTree is a package that turns a flat list of file paths into a directory structure.

usage:

import toFileTree  from 'toFileTree'

const files = ['index.html', 'content/index.html', 'content/leaf/index.html']
const fileTree = toFileTee(files)

fileTree will have a value of

{
    files: ['index.html'],
    directories: {
        'content': {
            files: ['index.html'],
            directories: {
                'leaf': {
                   files: ['index.html']
                }
            }
        }
    }
}
