I meet the same question today. let config in webpack.config.js: output.publicPath be equal to devServer.historyApiFallback.index and point out html file route。my webpack-dev-server version is 1.10.1 and work well. http://webpack.github.io/docs/webpack-dev-server.html#the-historyapifallback-option doesn't work, you must point out html file route.

for example

module.exports = {
    entry: "./src/app/index.js",
    output: {
        path: path.resolve(__dirname, 'build'),
        publicPath: 'build',
        filename: 'bundle-main.js'
    },
    devServer: {
        historyApiFallback:{
            index:'build/index.html'
        },
    },
};

historyApiFallback.index indicate that when url path not match a true file,webpack-dev-server use the file config in historyApiFallback.index to show in browser rather than 404 page. then all things about your route change let your js using react-router do it.

Question 2

I use Webpack dev server and browserHistory in React Router to manipulate with urls by HTML5 History API. historyapifallback-option does not work in my webpack config file. After refreshing http://localhost:8080/users or http://localhost:8080/products I got 404.

webpack.config.js

var webpack = require('webpack');
var merge = require('webpack-merge');

const TARGET = process.env.npm_lifecycle_event;

var common = {
    cache: true,
    debug: true,
    entry: './src/script/index.jsx',
    resolve: {
        extensions: ['', '.js', '.jsx']
    },
    output: {
        sourceMapFilename: '[file].map'
    },
    module: {
        loaders: [
            {
                test: /\.js[x]?$/,
                loader: 'babel-loader',
                exclude: /(node_modules)/
            }
        ]
    },
    plugins: [
        new webpack.ProvidePlugin({
            $: "jquery",
            jQuery: "jquery"
        })
    ]
};

if(TARGET === 'dev' || !TARGET) {
    module.exports = merge(common,{
        devtool: 'eval-source-map',
        devServer: {
            historyApiFallback: true
        },
        output: {
            filename: 'index.js',
            publicPath: 'http://localhost:8090/assets/'
        },
        plugins: [
            new webpack.DefinePlugin({
                'process.env.NODE_ENV': JSON.stringify('dev')
            })
        ]
    });
}

index.html

        <script type="text/javascript" src="http://localhost:8090/assets/index.js"></script>

index.jsx

import React, {Component} from 'react';
import ReactDOM from 'react-dom';
import {Router, Route, useRouterHistory, browserHistory, Link} from 'react-router';

  render() {
      return <div>
          I am home component
          <Link to="/users" activeClassName="active">Users</Link>
          <Link to="/products" activeClassName="active">Products</Link>

}

class Products extends Component{
  constructor(props) {
    super(props);
  }

  render() {
      return <div> I am Products component </div>;
  }
}

ReactDOM.render(
    <Router history={browserHistory} onUpdate={() => window.scrollTo(0, 0)}>
        <Route path="/" component={Home}/>
        <Route path="/users" component={Users} type="users"/>

I tried to change devServer in my config, but it didn't help:

devServer: {
    historyApiFallback: {
        index: 'index.html',
    }
},

devServer: {
    historyApiFallback: {
        index: 'index.js',
    }
},

devServer: {
    historyApiFallback: {
        index: 'http://localhost:8090/assets',
    }
},

devServer: {
    historyApiFallback: {
        index: 'http://localhost:8090/assets/',
    }
},

devServer: {
    historyApiFallback: {
        index: 'http://localhost:8090/assets/index.html',
    }
},

devServer: {
    historyApiFallback: {
        index: 'http://localhost:8090/assets/index.js',
    }
},

devServer: {
    historyApiFallback: {
        index: 'http://localhost:8090/assets/index.js',
    }
},
output: {
    filename: 'index.js',
            publicPath: 'http://localhost:8090/assets/'
},
