javascript - How to create multiple page app using react

Question

I have created a single page web app using react js. I have used webpack to create bundle of all components. But now I want to create many other pages. Most of pages are API call related. i.e. in the index.html, I have displayed content from API. I want to insert content in another page parsing data from API. Webpack compresses everything of react in a file which is bundle.js. However, the configuration of webpack is as follow:

const webpack = require('webpack');

var config = {
entry: './main.js',

output: {
    path:'./',
    filename: 'dist/bundle.js',
},

devServer: {
    inline: true,
    port: 3000
},

module: {
    loaders: [
        {
            test: /.jsx?$/,
            exclude: /node_modules/,
            loader: 'babel',

            query: {
                presets: ['es2015', 'react']
            }
        }
    ]
},

plugins: [
    new webpack.DefinePlugin({
        'process.env': {
            'NODE_ENV': JSON.stringify('production')
        }
    }),
    new webpack.optimize.UglifyJsPlugin({
        compress: {
            warnings: false
        }
    })
]
}

module.exports = config;

Now, I am confused what kind of configuration of webpack will be for other page or what is the correct way to build multi-pages app using react.js

Answer 1

(Make sure to install react-router using npm!)

To use react-router, you do the following:

1. Create a file with routes defined using Route, IndexRoute components

2. Inject the Router (with 'r'!) component as the top-level component for your app, passing the routes defined in the routes file and a type of history (hashHistory, browserHistory)

3. Add {this.props.children} to make sure new pages will be rendered there
4. Use the Link component to change pages

Step 1 routes.js

import React from 'react';
import { Route, IndexRoute } from 'react-router';

/**
 * Import all page components here
 */
import App from './components/App';
import MainPage from './components/MainPage';
import SomePage from './components/SomePage';
import SomeOtherPage from './components/SomeOtherPage';

/**
 * All routes go here.
 * Don't forget to import the components above after adding new route.
 */
export default (
  <Route path="/" component={App}>
    <IndexRoute component={MainPage} />
    <Route path="/some/where" component={SomePage} />
    <Route path="/some/otherpage" component={SomeOtherPage} />
  </Route>
);

Step 2 entry point (where you do your DOM injection)

// You can choose your kind of history here (e.g. browserHistory)
import { Router, hashHistory as history } from 'react-router';
// Your routes.js file
import routes from './routes';

ReactDOM.render(
  <Router routes={routes} history={history} />,
  document.getElementById('your-app')
);

Step 3 The App component (props.children)

In the render for your App component, add {this.props.children}:

render() {
  return (
    <div>
      <header>
        This is my website!
      </header>

      <main>
        {this.props.children}
      </main>

      <footer>
        Your copyright message
      </footer>
    </div>
  );
}

Step 4 Use Link for navigation

Anywhere in your component render function's return JSX value, use the Link component:

import { Link } from 'react-router';
(...)
<Link to="/some/where">Click me</Link>
