flatten-tree

Transforms a nested tree structure into a flat list.

Install

$ npm i flatten-tree

Use

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:

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