Rendering vis.js network into container via React.js

this works for me:

 var nodes = new vis.DataSet([
        {id: 1, label: 'Node 1'},
        {id: 2, label: 'Node 2'},
        {id: 3, label: 'Node 3'},
        {id: 4, label: 'Node 4'},
        {id: 5, label: 'Node 5'}
    ]);

    // create an array with edges
    var edges = new vis.DataSet([
        {from: 1, to: 3},
        {from: 1, to: 2},
        {from: 2, to: 4},
        {from: 2, to: 5}
    ]);

var data = {
        nodes: nodes,
        edges: edges
    };
    var options = {};

    // initialize your network!


var VisNetwork = React.createClass({

    componentDidMount(){
            var network = new vis.Network(this.refs.myRef, data, options);
  },

  render: function() {
    return <div ref="myRef"></div>;
  }
});

ReactDOM.render(
  <VisNetwork />,
  document.getElementById('container')
);

From React 16.3, it is recommended to use React.createRef Docs

Updating @Gino's answer with 16.3 style.

import { DataSet, Network } from 'vis';
import React, { Component, createRef } from "react";

const nodes = new DataSet([
  { id: 1, label: 'Node 1' },
  { id: 2, label: 'Node 2' },
  { id: 3, label: 'Node 3' },
  { id: 4, label: 'Node 4' },
  { id: 5, label: 'Node 5' }
]);

// create an array with edges
const edges = new DataSet([
  { from: 1, to: 3 },
  { from: 1, to: 2 },
  { from: 2, to: 4 },
  { from: 2, to: 5 }
]);

const data = {
  nodes: nodes,
  edges: edges
};
const options = {};

// initialize your network!


class VisNetwork extends Component {

  constructor() {
    super();
    this.network = {};
    this.appRef = createRef();
  }

  componentDidMount() {
    this.network = new Network(this.appRef.current, data, options);
  }

  render() {
    return (
      <div ref={this.appRef} />
    );
  }
}

Here is a modern example using functional components and React hooks.

package.json

{
  "dependencies": {
    "react": "16.13.0",
    "react-dom": "16.13.0",
    "vis-network": "7.4.0"
  }
}

VisNetwork.js

import React, { useEffect, useRef } from 'react';
import { DataSet, Network} from 'vis-network/standalone/esm/vis-network';

const VisNetwork = () => {
  // A reference to the div rendered by this component
  const domNode = useRef(null);

  // A reference to the vis network instance
  const network = useRef(null);

  // An array of nodes
  const nodes = new DataSet([
    { id: 1, label: 'Node 1' },
    { id: 2, label: 'Node 2' },
    { id: 3, label: 'Node 3' },
    { id: 4, label: 'Node 4' },
    { id: 5, label: 'Node 5' }
  ]);

  // An array of edges
  const edges = new DataSet([
    { from: 1, to: 3 },
    { from: 1, to: 2 },
    { from: 2, to: 4 },
    { from: 2, to: 5 }
  ]);

  const data = {
    nodes,
    edges
  };

  const options = {};

  useEffect(
    () => {
      network.current = new Network(domNode.current, data, options);
    },
    [domNode, network, data, options]
  );

  return (
    <div ref = { domNode } />
  );
};

export default VisNetwork;

Here is the modern Typescript way:

import React, { useEffect, useRef } from "react";
import {
  DataSet,
  Network,
  Options,
  Data,
} from "vis-network/standalone/esm/vis-network";

export const LogicTreePanel = () => {
  // A reference to the div rendered by this component
  const domNode = useRef<HTMLDivElement>(null);

  // A reference to the vis network instance
  const network = useRef<Network | null>(null);

  // An array of nodes
  const nodes = new DataSet([
    { id: 1, label: "Node 1" },
    { id: 2, label: "Node 2" },
    { id: 3, label: "Node 3" },
    { id: 4, label: "Node 4" },
    { id: 5, label: "Node 5" },
  ]);

  // An array of edges
  const edges = new DataSet([
    { from: 1, to: 3 },
    { from: 1, to: 2 },
    { from: 2, to: 4 },
    { from: 2, to: 5 },
  ]);

  const data: Data = {
    nodes,
    edges,
  };

  const options: Options = {};

  useEffect(() => {
    if (domNode.current) {
      network.current = new Network(domNode.current, data, options);
    }
  }, [domNode, network, data, options]);

  return (
    <div
      ref={domNode}
    />
  );
};
