How to include bootstrap css and js in reactjs app?

I am newb to reactjs, I want to include bootstrap in my react app

I have installed bootstrap by npm install bootstrap --save

Now, want to load bootstrap css and js in my react app.

I am using webpack.

webpack.config.js

var config = {
    entry: './src/index',

    output: {
        path: './',
        filename: 'index.js'
    },

    devServer: {
        inline: true,
        port: 8080,
        historyApiFallback: true,
        contentBase:'./src'
    },

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

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

module.exports = config;

My issue is “how to include bootstrap css and js in reactjs app from node_modules?” How to setup for bootstrap to include in my react app?
