pg-react-mindmap v1.1.3

React-nodemap

Made with create-react-library

react-nodemap(I prefer to call it react-mindmap, but it is massively used 😰) is a mindmap React component that I converted from Vue by hand,so you may expect some bugs in any stage from packaging to excution. Feel free to post any issue you find, I will try my best to take care of it.

the original Vue version: https://github.com/hellowuxin/mindmap

❗ Note

Node Data Structure Export

{
  name:'',
  children:[],
  // generated in the tree constructor, will be replaced if you have your own fields array
  size:[], 
  color:'',
  depth: 0,
  nodeId: 0,
}

• onDataChange will only fire when you add, delete, move branch, change sibling positions and change text of nodes(when a node input loses focus)
• specify the fields in fields as an array like ['id','createdAt'] to keep data clean when exporting, but 👇

! WARNING: avoid passing in fields with already taken names, see above node structure

🍻 Example

you can play around with the component <Nodemap /> even before adding any props, but be sure to add onDataChange func to update the var you passed into the value prop

React Class Component

import React, { Component } from 'react'

import Nodemap from 'react-nodemap'
import 'react-nodemap/dist/index.css'

class Example extends Component {
  constructor(props){
    super(props)
    this.state = {
      data: [
        {
          name: 'some text',
          children:[ 
            {
              name: 'some other text',
              children:[]
            }
          ]
        }
      ]
    }
  }

  onDataChange = (value) =>{
    this.setState({
      data: value
    })
  }

  render() {
    return 
    <Nodemap 
      defaultValue={this.state.data} 
      onDataChange={this.onDataChange}
      depthLimit={4}
      fields={['id','createdAt']}// output fields will be ['name', 'children','id','createdAt'], others will be omitted
    />
  }
}

or

React Hooks Component

import React, {useState, useEffect} from 'react'
import Nodemap from 'react-nodemap'

import 'react-nodemap/dist/index.css'

const App = () => {
  const [data,setData] = useState([
    {
      name: 'some text',
      children:[ 
        {
          name: 'some other text',
          children:[]
        }
      ]
    }
  ])

  return (
    <div>
      <Nodemap 
        value={data} 
        onDataChange={(value) => setData(value)}
        depthLimit={0}
        fields={['color','depth','id']}
      />
    </div>
  )
}

😵 Known problems

• change siblings position downward sometimes will not work or maybe crash
