Function default

converts a nested tree structure into a flat list structure

Example

import { tree2List } from "tree-handle-lib";
const inputTree = [
 {
   key: 1,
   name: "Parent 1",
   children: [
     {
       key: 2,
       name: "Child 1-1",
       children: [],
     },
     {
       key: 3,
       name: "Child 1-2",
       children: [
         {
           key: 4,
           name: "Grandchild 1-2-1",
           children: [],
         },
       ],
     },
   ],
 },
 {
   key: 5,
   name: "Parent 2",
   children: [
     {
       key: 6,
       name: "Child 2-1",
       children: [],
     },
   ],
 },
];
const _result = tree2List(inputTree);
// [
//   { key: 1, name: "Parent 1", parentKey: null },
//   { key: 2, name: "Child 1-1", parentKey: 1 },
//   { key: 3, name: "Child 1-2", parentKey: 1 },
//   { key: 4, name: "Grandchild 1-2-1", parentKey: 3 },
//   { key: 5, name: "Parent 2", parentKey: null },
//   { key: 6, name: "Child 2-1", parentKey: 5 },
// ];
