Diagram is the tool for making node based systems. Define your own behaviour of this react based diagram system and create your tool. Visual programming is trending right now so this is a good basis.

Live demo

Here is Live Demo of diagram used to create node based backend system

Add to yor project

$ npm install @slothking-online/diagram

$ git clone https://github.com/slothking-online/diagram
$ npm install
$ npm run start

Define spacebar menu actions

import { Graph } from '@slothking-online/diagram';
import * as React from 'react';
let allCategories = [
  {
    name: 'middlewares',
    items: [
      {
        name: 'middleware',
        type: 'middleware',
        inputs: [
          {
            name: ''
          }
        ],
        outputs: [
          {
            name: ''
          }
        ]
      }
    ]
  }
];

export const MyGraphComponent = () => <Graph categories={allCategories} />;

Now if you press spacebar when mouse is on the graph you get this menu, which creates nodes.

Serialization of data

<Graph
  categories={allCategories}
  serialize={(nodes, links) => {
    //here you receive nodes and links after every graph change
  }}
  validate={(node1, node2) => {
    // not necessary but you can add custom validation function between every node
  }}
/>
