### Playground
- Vanilla JS - https://codepen.io/ssshooter/pen/OJrJowN
- React - https://codesandbox.io/s/mind-elixir-3-x-react-18-x-vy9fcq
- Vue3 - https://codesandbox.io/s/mind-elixir-3-x-vue3-lth484

## Usage
### Install
#### NPM
```bash
npm i mind-elixir -S
```
```javascript
import MindElixir from 'mind-elixir'
```
#### Script tag
```html
```
### Init
```html
```
**Breaking Change** since 1.0.0, `data` should be passed to `init()`, not `options`.
```javascript
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
mouseSelectionButton: 0, // 0 for left button, 2 for right button, default 0
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
```javascript
// 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: ['π'],
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
```javascript
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
```javascript
// 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
```javascript
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
},
},
})
```
## Export as a Image
```typescript
const mind = {
/** mind elixir instance */
}
const downloadPng = async () => {
const blob = await mind.exportPng() // Get a Blob!
if (!blob) return
const url = URL.createObjectURL(blob)
const a = document.createElement('a')
a.href = url
a.download = 'filename.png'
a.click()
URL.revokeObjectURL(url)
}
```
## APIs

## Theme
```javascript
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',
},
})
```
Be aware that Mind Elixir will not observe the change of `prefers-color-scheme`. Please change the theme **manually** when the scheme changes.
