[javascript] Bootstrap modal in React.js

I've only used bootstrap cdn (css + js) to achieve "reactstrap" like solution. I've used props.children to pass dynamic data from parent to child components. You can find more about this here. In this way you have three separate components modal header, modal body and modal footer and they are totally independent from each other.

//Modal component
import React, { Component } from 'react';

export const ModalHeader = props => {
  return <div className="modal-header">{props.children}</div>;
};

export const ModalBody = props => {
  return <div className="modal-body">{props.children}</div>;
};

export const ModalFooter = props => {
  return <div className="modal-footer">{props.children}</div>;
};

class Modal extends Component {
  constructor(props) {
    super(props);
    this.state = {
      modalShow: '',
      display: 'none'
    };
    this.openModal = this.openModal.bind(this);
    this.closeModal = this.closeModal.bind(this);
  }

  openModal() {
    this.setState({
      modalShow: 'show',
      display: 'block'
    });
  }

  closeModal() {
    this.setState({
      modalShow: '',
      display: 'none'
    });
  }

  componentDidMount() {
    this.props.isOpen ? this.openModal() : this.closeModal();
  }

  componentDidUpdate(prevProps) {
    if (prevProps.isOpen !== this.props.isOpen) {
      this.props.isOpen ? this.openModal() : this.closeModal();
    }
  }

  render() {
    return (
      <div
        className={'modal fade ' + this.state.modalShow}
        tabIndex="-1"
        role="dialog"
        aria-hidden="true"
        style={{ display: this.state.display }}
      >
        <div className="modal-dialog" role="document">
          <div className="modal-content">{this.props.children}</div>
        </div>
      </div>
    );
  }
}

export default Modal;

//App component
import React, { Component } from 'react';
import Modal, { ModalHeader, ModalBody, ModalFooter } from './components/Modal';

import './App.css';

class App extends Component {
  constructor(props) {
    super(props);
    this.state = {
      modal: false
    };
    this.toggle = this.toggle.bind(this);
  }

  toggle() {
    this.setState({ modal: !this.state.modal });
  }

  render() {
    return (
      <div className="App">
        <h1>Bootstrap Components</h1>

        <button
          type="button"
          className="btn btn-secondary"
          onClick={this.toggle}
        >
          Modal
        </button>

        <Modal isOpen={this.state.modal}>
          <ModalHeader>
            <h3>This is modal header</h3>
            <button
              type="button"
              className="close"
              aria-label="Close"
              onClick={this.toggle}
            >
              <span aria-hidden="true">&times;</span>
            </button>
          </ModalHeader>
          <ModalBody>
            <p>This is modal body</p>
          </ModalBody>
          <ModalFooter>
            <button
              type="button"
              className="btn btn-secondary"
              onClick={this.toggle}
            >
              Close
            </button>
            <button
              type="button"
              className="btn btn-primary"
              onClick={this.toggle}
            >
              Save changes
            </button>
          </ModalFooter>
        </Modal>
      </div>
    );
  }
}

export default App;
