Usage

Install

NPM

npm i mind-elixir -S

import MindElixir from 'mind-elixir'
import 'mind-elixir/style.css'

Script tag

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

And in your CSS file:

@import 'https://cdn.jsdelivr.net/npm/mind-elixir/dist/style.css';

Init

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

import MindElixir from 'mind-elixir'
import 'mind-elixir/style.css'
import example from 'mind-elixir/dist/example1'

let options = {
  el: '#map', // or HTMLDivElement
  direction: MindElixir.LEFT,
  toolBar: true, // default true
  nodeMenu: true, // default true
  keypress: true, // default true
  locale: 'en', // [zh_CN,zh_TW,en,ja,pt,ru,ro] waiting for PRs
  overflowHidden: false, // default false
  mainLinkStyle: 2, // [1,2] default 1
  mouseSelectionButton: 0, // 0 for left button, 2 for right button, default 0
  contextMenu: {
    focus: true,
    link: true,
    extend: [
      {
        name: 'Node edit',
        onclick: () => {
          alert('extend menu')
        },
      },
    ],
  }, // default true
  before: {
    insertSibling(type, obj) {
      return true
    },
  },
  // Custom markdown parser (optional)
  // markdown: (text) => customMarkdownParser(text), // provide your own markdown parser function
}

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('selectNodes', nodes => {
  console.log(nodes)
})

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

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

Markdown Support

Mind Elixir supports custom markdown parsing:

// Disable markdown (default)
let mind = new MindElixir({
  // markdown option omitted - no markdown processing
})

// Use custom markdown parser
let mind = new MindElixir({
  markdown: text => {
    // Your custom markdown implementation
    return text
      .replace(/\*\*(.*?)\*\*/g, '<strong>$1</strong>')
      .replace(/\*(.*?)\*/g, '<em>$1</em>')
      .replace(/`(.*?)`/g, '<code>$1</code>')
  },
})

// Use any markdown library (e.g., marked, markdown-it, etc.)
import { marked } from 'marked'
let mind = new MindElixir({
  markdown: text => marked(text),
})

Operation Guards

let mind = new MindElixir({
  // ...
  before: {
    async addChild(el, obj) {
      await saveDataToDb()
      return true
    },
  },
})

Export as a Image

Install @zumer/snapdom, then:

import { snapdom } from '@zumer/snapdom'

const download = async () => {
  const result = await snapdom(mind.nodes)
  await result.download({ format: 'jpg', filename: 'my-capture' })
}

For other export formats and advanced options, see the Mind Elixir documentation.

Deprecated API

⚠️ Deprecated: The mind.exportSvg() method is deprecated and will be removed in a future version.

// DEPRECATED - Do not use in new projects
const svgData = await mind.exportSvg()

Theme

const options = {
  // ...
  theme: {
    name: 'Dark',
    // main lines color palette
    palette: ['#848FA0', '#748BE9', '#D2F9FE', '#4145A5', '#789AFA', '#706CF4', '#EF987F', '#775DD5', '#FCEECF', '#DA7FBC'],
    // overwrite css variables
    cssVar: {
      '--main-color': '#ffffff',
      '--main-bgcolor': '#4c4f69',
      '--color': '#cccccc',
      '--bgcolor': '#252526',
      '--panel-color': '255, 255, 255',
      '--panel-bgcolor': '45, 55, 72',
    },
    // all variables see /src/index.less
  },
  // ...
}

// ...

mind.changeTheme({
  name: 'Latte',
  palette: ['#dd7878', '#ea76cb', '#8839ef', '#e64553', '#fe640b', '#df8e1d', '#40a02b', '#209fb5', '#1e66f5', '#7287fd'],
  cssVar: {
    '--main-color': '#444446',
    '--main-bgcolor': '#ffffff',
    '--color': '#777777',
    '--bgcolor': '#f6f6f6',
  },
})
