Webpack dev server bootstrapping twice

Question

Webpack dev server is bootstrapping twice for an unknown reason. (Note that only the dev-server has this problem, if I bundle the files, everything runs ok).

I'm seeing this line executing twice:

// Load entry module and return exports
  return hotCreateRequire(790)(__webpack_require__.s = 790); 

I can also see this line two times in my browser log:

[HMR] Waiting for update signal from WDS...

These are the used versions

"webpack": "^2.1.0-beta.21"
"webpack-dev-server": "^2.1.0-beta.4",

Answer 1

I was using HtmlWebpackPlugin,

inject: false

Did the magic as stated in this question:

All my code runs twice when compiled by Webpack
