How to use data toggle collapse in Reactjs with Bootstrap?

Question

I am using pure Bootstrap with Reactjs and I have build a navBar using Bootstrap component but the problem I am facing is with data toggle collapse it is not working.

When I shrink my display view size then the hamburger icon becomes visible but when I click on it then nothing happens. While it works perfect with pure HTML and JS but not working with reactjs.

Here is index.js file

import '../node_modules/bootstrap/dist/css/bootstrap.min.css';
import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import App from './App';
import registerServiceWorker from './registerServiceWorker';

ReactDOM.render(<App />, document.getElementById('root'));
registerServiceWorker();

Here is app.js

import React, { Component } from 'react';
import './App.css';
import NavBar from './components/navBar/navBar';

class App extends Component {
  render() {
    return (
      <div>
      <NavBar />
    </div>
    );
  }
}

export default App;

here is NavBar.js file

import React, { Component } from 'react';

class NavBar extends Component {
  render() {
    return (
      <div>

        <nav className="navbar navbar-expand-lg navbar-light bg-light">
          <a className="navbar-brand" href="/">Navbar</a>
          <button className="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNavAltMarkup" aria-controls="navbarNavAltMarkup" aria-expanded="false" aria-label="Toggle navigation">
            <span className="navbar-toggler-icon"></span>
          </button>
          <div className="collapse navbar-collapse" id="navbarNavAltMarkup">
            <div className="navbar-nav">
              <a className="nav-item nav-link active" href="/">Home <span class="sr-only">(current)</span></a>
              <a className="nav-item nav-link" href="/">Features</a>
              <a className="nav-item nav-link" href="/">Pricing</a>
              <a className="nav-item nav-link" href="/">logout</a>
            </div>
          </div>
        </nav>
      </div>
    );
  }
}

export default NavBar;

This is complete code I have used for navBar.

Bootstrap menu toggle is a JS functionality. It's not a good idea to mix the JS part of Bootstrap with ReactJS, since both libraries manipulate the DOM and it can lead to bigger problems.

I suggest implementing the small functionality you need. Most of the menu toggle is just a class toggle thing.

import React, { Component } from "react";

export default class Menu extends Component {

  constructor(props) {
    super(props);
    this.state = {
      menu: false
    };
    this.toggleMenu = this.toggleMenu.bind(this);
  }

  toggleMenu(){
    this.setState({ menu: !this.state.menu })
  }

  render() {

  const show = (this.state.menu) ? "show" : "" ;

  return (

    <nav className="navbar navbar-expand-lg navbar-light bg-light">
      <a className="navbar-brand" href="/">Navbar</a>
      <button className="navbar-toggler" type="button" onClick={ this.toggleMenu }>
        <span className="navbar-toggler-icon"></span>
      </button>
      <div className={"collapse navbar-collapse " + show}>
        <div className="navbar-nav">
          <a className="nav-item nav-link active" href="/">Home <span class="sr-only">(current)</span></a>
          <a className="nav-item nav-link" href="/">Features</a>
          <a className="nav-item nav-link" href="/">Pricing</a>
          <a className="nav-item nav-link" href="/">logout</a>
        </div>
      </div>
    </nav>

  );
  }
}

There is an equivalent library called "react-bootstrap" that you can use to style your components the same way as you would use bootstrap https://react-bootstrap.github.io. This way you can follow react and bootstrap best practices without making unnecessary manipulations to do DOM which can sometimes bring unwanted side effects.
