A koa middleware works as development server for webpack. Well tested.

• Koa v1.x

  const webpackDevServer = require('koa-webpack-dev');
  app.use(webpackDevServer(settings));

npm install koa-webpack-dev

• Can be integrated into your koa application as easy as using a serveStatic middleware. Just don't use it in production mode.

var koa = require('koa');
var webpackDevServer = require('koa-webpack-dev');
var app = koa();

app.use(webpackDevServer({
    config: './webpack.config.js'
}));

app.listen(2333);

• options:
  • config: can be the content of webpack.config.js or a string specified the path of webpack.config.js
  • watchOptions: options to be passed into the watch api of webpack. webpack#watching
  • defaultPage: default entry page for url mapped to a directory. default: index.html
  • webRoot: web root path. default: build path
