like below fixes the issue You will need webpack to transpile you components written in JSX to JS. Then you can import react like
code :
import React from 'react';
var webpack = require('webpack');
var path = require('path');

module.exports ={

    context: path.join(__dirname, "src"),
    devtool: "inline-sourcemap",
    entry: "./js/client.js",
    module: {
        loaders: [
            {
                test: /\.js?$/,
                exclude: /(node_modules|bower_components)/,
                loader: 'babel-loader',
                query: {
                    presets: ['react', 'es2015','stage-0'],
                    plugins: ['react-html-attrs', 'transform-decorators-legacy']
                }
            }
        ]
    },
    output: {
        path: __dirname+ "/src",
        filename: "client.min.js"
    }
}

ReactJS - how create two or more components in same page

ReactJS - how create two or more components in same page

hop of those help? I'm new user of ReactJS and I bumped in a point. I'm creating a generic map component, it works perfectly. However, only can render one component by page. I would like to instead use getElementById, I could use getElementsByClassName. , You can just iterate the result from getElementsByClassName:
code :
function renderEls(elements) {
    for (var i = 0; i < elements.length; i++) {
        if( $(elements[i]).attr('comp-url') !== undefined ) {
            var url = $(elements[i]).attr('comp-url');
        }
        ReactDOM.render(<MyMap url={url} />, elements[i]);
    }
}

renderEls(document.getElementsByClassName("MyMap"));

I wish this helpful for you So I guess I'd start by asking why you think Navigation should have this.props.children - I know it has two children, but it isn't passed them as props. It is creating them. It would receive a children props if it was invoked like this:
code :
<Navigation>
  <div>This is a child!</div>
</Navigation>
var Navigation = React.createClass({

  getInitialState: function() {
    var endpoints = require("./data/naviEnd.js");
    return {
      endpoints: endpoints
    }             
  },

  changeEndpoints: function() {
    // Get new endpoints somehow
    this.setState({endpoints: newEndpoints});
  }

  render: function() {
    return(
      <div id="navigation">
        <NavEndpt endpoints={this.state.endpoints} />
      </div>
    )
  }
});

To fix the issue you can do I have discovered couple issues while improving the solution to this issue:
When i would re-hydrate auth values, they were not properly reset when user logged out Proper way to manage auth is through the router and not though the components. This prevents needless api calls or state changes. I did some research and found the following guide: https://codepen.io/bradwestfall/project/editor/XWNWge?preview_height=50&open_file=src/app.js which i have used to adjust the auth issue
code :
import React from 'react';
import { Route, Redirect } from 'react-router-dom';
import PropTypes from 'prop-types';
import cookies from 'universal-cookie';

class AuthorizedRoute extends React.Component {
  componentWillMount() {}

  getAuth() {
    const cookie = new cookies();
    return cookie.get('auth');
  }

  render() {
    const { component: Component, ...rest } = this.props;
    return (
      <Route
        {...rest}
        render={props => {
          return this.getAuth() ? (
            <Component {...props} />
          ) : (
            <Redirect to="/login" />
          );
        }}
      />
    );
  }
}

AuthorizedRoute.propTypes = {
  render: PropTypes.any,
  component: PropTypes.any
};

export default AuthorizedRoute;
import React from 'react';
import { render } from 'react-dom';
import { Provider } from 'react-redux';
import store from './redux/store';
import { BrowserRouter, Route, Switch } from 'react-router-dom';

import LoginForm from './components/LoginForm/LoginForm';
import Home from './components/HomePage/home';
import AuthorizedRoute from './.../AuthorizedRoute';

class App extends React.Component {
  render() {
    return (
      <Provider store={store}>
        <BrowserRouter>
          <div>
            <Route />
            <Switch>
              <AuthorizedRoute exact path={'/'} component={Home} />
              <Route
               exact
               path={'/login'}
               render={props => <LoginForm {...props} />}
               />
              <Route path="*" render={props => <LoginForm {...props} />} />
            </Switch>
          </div>
        </BrowserRouter>
      </Provider>
    );
  }
}
render(<App />, document.getElementById('root'));
componentDidMount() {
    const cookie = new cookies();
    const auth = cookie.get('auth');
    if (auth) {
      this.props.history.push('/');
    } else {
      if (this.props.isLoginSuccess) {
        this.props.setLogingSuccess(false);
        this.props.setLoggedUser(null);
      }
    }
  }
  componentWillReceiveProps(nextProps) {
    const { isLoginSuccess } = this.props;
    if (!isLoginSuccess && nextProps.isLoginSuccess) {
      this.props.history.push('/');
    }
  }
case REHYDRATE:
      var incoming = action.payload.reducer;
      if (incoming) {
        return {
          ...state,
          loggedUser: incoming.loggedUser,
          isLoginSuccess: incoming.isLoginSuccess,
        };
      }
      break;
Load ReactJS component on the same page overwriting other components

Hope this helps So you want a grandchild of the Home component to override the home component? You simply can't do that this way.
If the reason you want to override, is that you don't want to show the Video and Featured component simply move up the 'step' logic to the Home component. You could then return like this:
code :
switch (step) {
      case 1:
        return (
          <Video />
          <Featured />
          <Plan
            nextStep={this.nextStep}
            handleChange={this.handleChange}
            values={values}
          />
        );
      case 2:
        return (
          <Account
            nextStep={this.nextStep}
            prevStep={this.prevStep}
            handleChange={this.handleChange}
            values={values}
          />
        );
      case 3:
       return (
        <Video>
        <Featured />
        <ThankYou />
       );

    }
class MyComponent extends React.Component {

  \\all your logic and inside the render function:
  switch (step) {
      case 1:
        return (
          <Home {...props}/>
        );
      case 2:
        return (
          <Account
            {...props}
          />
        );
      case 3:
       return (
         <Home {...props}/>
       );

    }
  }

The links do not render the components of ReactJS. The URL changes but the page does not?
