I was setting up a project today using Webpack, React and Bootstrap without jQuery. This supposed to be a straight forward task but turns out I have spent a bit of time to figure it out. So I’m going to document the steps as shown below:

Firstly, install all dependencies:

npm install react react-dom bootstrap react-bootstrap babel-preset-react --save

npm install webpack css-loader style-loader file-loader url-loader babel-core babel-loader babel-preset-es2015 --save-dev

Then, add the loaders in your webpack.conf.js:

var path = require('path');
var webpack = require('webpack');

module.exports = {
  entry: './main.js',
  output: { path: __dirname, filename: 'bundle.js' },
  module: {
    loaders: [
      {
        test: /.jsx?$/,
        loader: 'babel-loader',
        exclude: /node_modules/,
        query: {
          presets: ['es2015', 'react']
        }
      },
      { 
        test: /\.css$/, 
        loader: "style-loader!css-loader" 
      },
      { 
        test: /\.png$/, 
        loader: "url-loader?limit=100000" 
      },
      { 
        test: /\.jpg$/, 
        loader: "file-loader" 
      },
      {
        test: /\.(woff|woff2)(\?v=\d+\.\d+\.\d+)?$/, 
        loader: 'url?limit=10000&mimetype=application/font-woff'
      },
      {
        test: /\.ttf(\?v=\d+\.\d+\.\d+)?$/, 
        loader: 'url?limit=10000&mimetype=application/octet-stream'
      },
      {
        test: /\.eot(\?v=\d+\.\d+\.\d+)?$/, 
        loader: 'file'
      },
      {
        test: /\.svg(\?v=\d+\.\d+\.\d+)?$/, 
        loader: 'url?limit=10000&mimetype=image/svg+xml'
      }
    ]
  },
};

Next, in your main.js (or whatever your entry file), import Bootstrap CSS:

import App from './app.jsx';
import Bootstrap from 'bootstrap/dist/css/bootstrap.css';

Finally, in your app.jsx, import react bootstrap:

import React from 'react';
import ReactDOM from 'react-dom';
import { Button } from 'react-bootstrap';

const buttonsInstance = (
  <Button>Click me!</Button>
);

ReactDOM.render(buttonsInstance, document.getElementById('here'));

Not to mention you also need the div with this id as well as the bundle.js:

<!doctype html>
<html>
  <head>
    <meta charset="UTF-8">
    <title>Hello React</title>
  </head>
  <body>
    <div id="here"></div>
    <script src="bundle.js"></script>
  </body>
</html>

That’s is it! Let me know if you have any questions.
