A pure function to convert a map into a tree structure. Created by @romseguy and merged from romseguy/map2tree.

The following opinions must be taken into account since the primary use case of this library is redux-devtools-chart-monitor:

  • Objects and arrays deeply nested within collections are not converted into a tree structure. See someNestedObject and someNestedArray in the output below, or the corresponding test.
  • Provides support for Immutable.js data structures (only List and Map though).

Usage

map2tree(
  someMap,
  (options = {
    key: 'state', // the name you want for as the root node of the output tree
    pushMethod: 'push', // use 'unshift' to change the order children nodes are added
  })
);

Input

const someMap = {
  someReducer: {
    todos: [
      { title: 'map', someNestedObject: { foo: 'bar' } },
      { title: 'to', someNestedArray: ['foo', 'bar'] },
      { title: 'tree' },
      { title: 'map2tree' },
    ],
    completedCount: 1,
  },
  otherReducer: {
    foo: 0,
    bar: { key: 'value' },
  },
};

Output

{
  name: `${options.key}`,
  children: [
    {
      name: 'someReducer',
      children: [
        {
          name: 'todos',
          children: [
            {
              name: 'todo[0]',
              object: {
                title: 'map',
                someNestedObject: {foo: 'bar'}
              }
            },
            {
              name: 'todo[1]',
              object: {
                title: 'to',
                someNestedArray: ['foo', 'bar']
              }
            },
            // ...
          ]
        },
        // ...
      ]
    },
    {
      name: 'otherReducer',
      children: [
        {
          name: 'foo',
          value: 0
        },
        {
          name: 'bar',
          object: {
            key: 'value'
          }
        }
      ]
    }
  ]
