// webpack.config.js
var path = require( "path" );
var webpack = require( 'webpack' );

module.exports = {
  entry: {
    app: [ "webpack-hot-middleware/client?reload=1", "./src/main.js" ]
  },
  output: {
    path: path.resolve( __dirname, 'dist' ),

var app = new Koa()
var compiler = webpack( webpackConf );
var middleware = koaWebpack({
  compiler:compiler , 
  dev:{
  noInfo: false,
  publicPath: webpackConf.output.publicPath
} 
}) 
app.use( middleware  )
app.use( ctx => {
  console.log(middleware.dev.fileSystem);
  const htmlBuffer = middleware.dev.fileSystem.readFileSync(`./index.html`);
  ctx.type = 'html';
  ctx.body = htmlBuffer; 
} )
app.listen( 3000 );

Expected Behavior

just rebuild html files in stream but do not need press F5 when change index.html

Actual Behavior

get error

MemoryFileSystem { data: { home: { '': true, clyde: [Object] } } }

How can we reproduce the behavior?

git clone https://github.com/dxcqcv/koa-demo.git then run node app.js in that

webpack-hot-middleare/app.js:37
