Convert a hierarchy from flat to nested representation.
var FlatToNested, flatToNested, flat;
FlatToNested = require('flat-to-nested');
flatToNested = new FlatToNested( /* can take a config object to use other property names */ );
flat = [
{id: 111, parent: 11},
{id: 11, parent: 1},
{id: 12, parent: 1},
{id: 1}
];
var nested = flatToNested.convert(flat);
console.log(nested);
// {
// id: 1,
// children: [
// {
// id: 11,
// children: [
// {
// id: 111
// }
// ]
// },
// {
// id: 12
// }
// ]
// }The constructor accepts an optional object with some or all of these properties:
flatToNested = new FlatToNested({
// The name of the property with the node id in the flat representation
id: 'id',
// The name of the property with the parent node id in the flat representation
parent: 'parent',
// The name of the property that will hold the children nodes in the nested representation
children: 'children'
