Chkflow

Chkflow is a react component editor/view for tree and graph data structures inspired by workflowy's interface.

Integrate it into your react project:

yarn add chkflow

or

npm install -S chkflow

Usage:

Example usage with javascript:

import './App.css';
import ChkFlow from 'chkflow';

function getNodes(){
  let savedNodes = window.localStorage.getItem('chkFlowNodes')

  if (savedNodes) {
    console.log('retrieved nodes')
    let nodes = JSON.parse(savedNodes)
    return nodes;
  }

}

function getEnv(){
  let savedEnv = window.localStorage.getItem('chkFlowEnvironment')
  if (savedEnv){
    console.log('retrieved environment')
    let environment = JSON.parse(savedEnv);
    return environment
  }
}


function setStateCallback(state){
  window.localStorage.setItem('chkFlowEnvironment', JSON.stringify(state.environment));
  window.localStorage.setItem('chkFlowNodes', JSON.stringify(state.nodes));
}

function App() {



  const nodes = getNodes();
  const environment = getEnv();
  const settings = {
    setStateCallback: setStateCallback,
    nodes: nodes,
    environment: environment
  }  



  return (



      <ChkFlow {...settings} />



  );
}

export default App;

Example usage with typescript:

import './App.css';
import ChkFlow from 'chkflow';
import type {
  ChkFlowEnvironment,
  ChkFlowNodes,
  ChkFlowSettings,
  ChkFlowState,
  ChkFlowNode
} from 'chkflow'

function getNodes(): ChkFlowNodes | undefined{
  let savedNodes = window.localStorage.getItem('chkFlowNodes')

  if (savedNodes) {
    console.log('retrieved nodes')
    let nodes = JSON.parse(savedNodes)
    return nodes;
  }

}

function getEnv(): ChkFlowEnvironment | undefined{
  let savedEnv = window.localStorage.getItem('chkFlowEnvironment')
  if (savedEnv){
    console.log('retrieved environment')
    let environment = JSON.parse(savedEnv);
    return environment
  }
}


function setStateCallback(state: ChkFlowState): void{
  window.localStorage.setItem('chkFlowEnvironment', JSON.stringify(state.environment));
  window.localStorage.setItem('chkFlowNodes', JSON.stringify(state.nodes));
}

function App() {



  const nodes = getNodes();
  const environment = getEnv();
  const settings: ChkFlowSettings = {
    setStateCallback: setStateCallback,
    nodes: nodes as ChkFlowNodes,
    environment: environment as ChkFlowEnvironment
  }  



  return (



      <ChkFlow {...settings} />



  );
}

export default App;

Structure of Nodes: e.g.

const dummyNodes = {
    '0' : { text: '[root] (you should not be seeing this)', rel: {'child': ['1','3']}, isCollapsed: false },
    '1' : { text: 'chores', rel: {'child': ['5', '2']}, isCollapsed: false  },
    '2' : { text: 'clean', rel: {'child': ['4']}, isCollapsed: false  },
    '3' : { text: 'study', rel: {'child': []}, isCollapsed: false  },
    '4' : { text: 'bathroom', rel: {'child': []}, isCollapsed: false  },
    '5' : { text: 'groceries', rel: {'child': ['6','7']}, isCollapsed: false  },
    '6' : { text: 'milk', rel: {'child': []}, isCollapsed: false  },
    '7' : { text: 'eggs', rel: {'child': []}, isCollapsed: false  },
}
const dummyEnvironment = {
    homePath: [{rel:'root',id:'0'}, {rel:'child', id:'1'}, {rel:'child', id:'5'}] as Types.NodePath,
    activeNode: null,
}
