Hot module replacement for Silhouette Play React Seed Template doesn't work


Hi First of all thanks for creating this Silhouette Play React Seed Template, this is really handy and save me time on scarfolding.

I cloned the template from I started it by running sbt run, the applications starts and I can login/ sign up. However when I make changes to /silhouette-play-react-seed/app-ui/src/routes/Admin/components/Dashboard/Dashboard.jsx. the change didn’t trigger a module reload. Just wondering did I done anything wrong?
I’m running Ubuntu 16 and my google chrome version is Version 61.0.3163.79 (Official Build) (64-bit)

Btw sbt test runs all test successfully but just hangs at the end.



You’re welcome :+1:

Yes I’ve the same issue. Sometimes it works and sometimes it doesn’t work. I hadn’t the time to dive deeper into the issue. Let me know if you find a solution for the issue.

Best regards,


Thanks Christian. I’ll give it a go.



today I stumbled over a CORS issue in my application where the webpack-dev-server needs "Access-Control-Allow-Origin": "*" header set.

By searching how this could be set I’ve found the two following issues:

Today I updated webpack-dev-server from 2.4.1 to 2.4.3 and suddenly HMR stopped working until I added this to my webpack config file:

Could you please change the line:


['neutrino-preset-react', {
  devServer: {
    headers: {
      "Access-Control-Allow-Origin": "*",


@ryan_Li Does it work for you?


Hi Akkie,
sorry didn’t get a chance to reply. I pulled the master a few days ago and HMR works after that so i assume thw fix worked for me.

Thanks for fixing that.
