flatten-tree

--------------

Transforms a nested tree structure into a flat list.

Install

``bash
$ npm i flatten-tree
`

Use

`javascript
import flattenTree from 'flatten-tree';

const tree = [
{
name: 'item1',
children: [
{
name: 'item2',
children: [
{name: 'item3'}
]
},
{name: 'item4'}
]
}
];

const options = {
initNode: node => node, // <= default, consider node => _.clone(node) to avoid mutating the tree
};

const list = flattenTree(tree, 'children', options);
`

Results in:

`javascript
[
{id: 1, name: 'item1', children: [2, 4]},
{id: 2, name: 'item2', children: [3]},
{id: 3, name: 'item3'},
{id: 4, name: 'item4'}
]
`

Test
