hot-module-reload v0.4.1

What?

If you need to reload only part of your app whithout restarting whole process when code required from this part was changed, then hot-module-reload fit your needs.

Install

$ npm install hot-module-reload --save

How to use?

Pass function to hot-module-reload, it will run it synchronously and then re-run it every time code required from this function is changed.

var HotReload = require('hot-module-reload');

var devServer = { close:() => {} };
HotReload(() => {
  var config = require('./webpack.client.config');
  devServer.close();
  devServer = new webpackDevServer(webpack(config), {
    publicPath: config.output.publicPath,
    proxy: {
      '*': 'http://localhost:' + port
    }
  });
  devServer.listen(devPort, () => {
    debug('dev server started on port ' + devPort);
  });
});

var appServer = { close:(cb) => { cb(); } };
HotReload(() => {
  var app = require('./server/app');
  appServer.close(() => {
    appServer = app.listen(port, () => {
      debug('app server started on port ' + port);
    });
  })
});

In this example dev server and app server will be reloaded separately, and process will not crash if updated code doesn't compile.
