Usage

Install

NPM

npm i mind-elixir -S
import MindElixir from 'mind-elixir'

Script tag

<script src="https://cdn.jsdelivr.net/npm/mind-elixir/dist/MindElixir.js"></script>

Init

<div id="map"></div>
<style>
  #map {
    height: 500px;
    width: 100%;
  }
</style>

Breaking Change since 1.0.0, data should be passed to init(), not options.

import MindElixir from 'mind-elixir'
import example from 'mind-elixir/dist/example1'

let options = {
  el: '#map', // or HTMLDivElement
  direction: MindElixir.LEFT,
  draggable: true, // default true
  contextMenu: true, // default true
  toolBar: true, // default true
  nodeMenu: true, // default true
  keypress: true, // default true
  locale: 'en', // [zh_CN,zh_TW,en,ja,pt,ru] waiting for PRs
  overflowHidden: false, // default false
  mainLinkStyle: 2, // [1,2] default 1
  contextMenuOption: {
    focus: true,
    link: true,
    extend: [
      {
        name: 'Node edit',
        onclick: () => {
          alert('extend menu')
        },
      },
    ],
  },
  before: {
    insertSibling(el, obj) {
      return true
    },
    async addChild(el, obj) {
      await sleep()
      return true
    },
  },
}

let mind = new MindElixir(options)

mind.install(plugin) // install your plugin

// create new map data
const data = MindElixir.new('new topic')
// or `example`
// or the data return from `.getData()`
mind.init(data)

// get a node
MindElixir.E('node-id')

Data Structure

// whole node data structure up to now
const nodeData = {
  topic: 'node topic',
  id: 'bd1c24420cd2c2f5',
  style: { fontSize: '32', color: '#3298db', background: '#ecf0f1' },
  expanded: true,
  parent: null,
  tags: ['Tag'],
  icons: ['😀'],
  hyperLink: 'https://github.com/ssshooter/mind-elixir-core',
  image: {
    url: 'https://raw.githubusercontent.com/ssshooter/mind-elixir-core/master/images/logo2.png', // required
    // you need to query the height and width of the image and calculate the appropriate value to display the image
    height: 90, // required
    width: 90, // required
  },
  children: [
    {
      topic: 'child',
      id: 'xxxx',
      // ...
    },
  ],
}

Event Handling

mind.bus.addListener('operation', operation => {
  console.log(operation)
  // return {
  //   name: action name,
  //   obj: target object
  // }

  // name: [insertSibling|addChild|removeNode|beginEdit|finishEdit]
  // obj: target

  // name: moveNode
  // obj: {from:target1,to:target2}
})

mind.bus.addListener('selectNode', node => {
  console.log(node)
})

mind.bus.addListener('expandNode', node => {
  console.log('expandNode: ', node)
})

Data Export And Import

// data export
const data = mind.getData() // javascript object, see src/example.js
mind.getDataString() // stringify object
mind.getDataMd() // markdown

// data import
// initiate
let mind = new MindElixir(options)
mind.init(data)
// data update
mind.refresh(data)

Operation Guards

let mind = new MindElixir({
  // ...
  before: {
    insertSibling(el, obj) {
      console.log(el, obj)
      if (this.currentNode.nodeObj.parent.root) {
        return false
      }
      return true
    },
    async addChild(el, obj) {
      await sleep()
      if (this.currentNode.nodeObj.parent.root) {
        return false
      }
      return true
    },
  },
})
