HMR and Rails 5.1.4

[eadz]

I followed the HMR instructions on a new rails app, and it doesn't seem to work.

The Instructions don't match the code in the latest rails/webpacker setup.

I have this in my config/webpack/development.js

const environment = require('./environment')

const configureHotModuleReplacement = require('webpacker-react/configure-hot-module-replacement')

module.exports = configureHotModuleReplacement(environment.toWebpackConfig());

and in packs/application.js changed the following
-import WebpackerReact from 'webpacker-react'; +import WebpackerReact from 'webpacker-react/hmr';

Finally, added this

if (module.hot) 
   module.hot.accept('pages/MyRoot', () =>
    WebpackerReact.renderOnHMR(MyRoot) )

The output of the server ( using --hot ) is this:

There is nothing in the browser console to indicate any error, just when I edit a file the whole page reloads. Any ideas?

Can you please show the whole application.js file (or at least the WebpackerReact.setup call and any Webpacker -related lines)?
Also, what is displayed in your console when you load the page, and then when you edit a file?
