wish helps you flowhub/the-graph expects a global React variable and It worked out by adding react and hammer in the index.html in the following manner:
code :
<body>
<div class="container"></div>
</body>
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.4.2/react.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/hammer.js/2.0.8/hammer.min.js"></script>
<script src="app/bundle.js"></script>
</html>

like below fixes the issue So the issue is here: If you are going to use the Square component, you need to create a class and then import it in main.js.
So you might have something like this:
code :
// src/square.js
import React, { Component } from 'react';
export default class Square extends Component {
  render() {
    return <div>Square</div>;
  }
}
// src/main.js
import React from "react";
import ReactDOM from "react-dom";
import "./index.css";
import App from "./App";
import * as serviceWorker from "./serviceWorker";
import Square from './square';

ReactDOM.render(<App />, document.getElementById("root"));
serviceWorker.unregister();

class Board extends React.Component {

    renderSquare() {
      return <Square />;
    }
    render() {
      return this.renderSquare();
    }

}

I wish this helpful for you namebox is a function not a component. You are trying to invoke it inside the sayHello function as a component. Try this.namebox(name) instead. You are not suppose to create a component within a component so namebox is just a function and it should start with a lower case letter.

around this issue Trying to test Formik with React. Below is the Formik Component: , Just ran into this myself. Was able to get past it using setImmediate
code :
describe('handleChange', () => {
  it('sets values state', async done => {
    const wrapper = mount(
      <Router>
        <LoginForm />
      </Router>
    );

    wrapper.find('input[id="email"]').simulate('change', {
      persist: noop,
      target: {
        id: 'email',
        value: 'test@email.com'
      }
    });

    setImmediate(() => {
      expect(wrapper.find('input[id="email"]').props().value).toEqual(
        'test@email.com'
      );
      done();
    });
  });
});
