Why can I only hit my react/webpack app at root (/)? - reactjs

Question

I spent today setting up react-transform with the hot-loader. I have an app with 2 routes, / and /reports. I can hit the / and then click on a Link to take me to /reports and it works fine, but it I try to go to /reports straight away, then I get a 404. Here is my webpack.config.js
module.exports = {
devtool: 'source-map',
entry: {
app: [
'./App.js',
'webpack-hot-middleware/client'
],
vendors: vendors
},
output: {
filename: './bundle.[hash].js',
chunkFilename: './[id].[hash].js',
path: __dirname + '/dist'
},
module: {
loaders: [
{
test: /\.js?$/,
exclude: /(node_modules)/,
loader: 'babel',
query: {
presets: ['react', 'es2015']
}
}, {
test: /\.scss$/,
loaders: ["style", "css", "sass"]
},
{
test: /\.(png|jpg)$/,
loader: 'url-loader?limit=8192'
}
]
},
plugins: [
new HtmlWebpackPlugin({
template: 'index.ejs'
}),
new CommonsPlugin({
name: 'vendors',
filename: 'vendors.js',
minChunks: Infinity
}),
new CleanWebpackPlugin(['dist'], {
root: __dirname,
verbose: true,
dry: false
}),
new webpack.optimize.OccurenceOrderPlugin(),
new webpack.HotModuleReplacementPlugin(),
new webpack.NoErrorsPlugin()
]
};
And here is my server.js
var app = express();
var compiler = webpack(webpackConfig);
app.use(webpackDevMiddleware(compiler));
app.use(webpackHotMiddleware(compiler));
app.use(express.static('/'));
app.listen(3000);
I have tried adding a route with
app.get('*', function(req, res) {
res.sendFile(path.join(__dirname, 'dist', 'index.html'));
});
But /dist/index.html is not there because of the hot-loader has it in memory. The exact error is
Error: ENOENT: no such file or directory, stat '/Users/jason/Developer/stack/webapp/dist/index.html'
at Error (native)
What do I need to change in my configuration?

Answer 1

My express server was set up wrong. I added this route to express:
app.get('*', function(req, res) {
var memoryFs = compiler.outputFileSystem;
var index = path.join(webpackConfig.output.path, 'index.html');
var html = memoryFs.readFileSync(index);
res.end(html)
});
And now I am working perfectly.
