According to the webpack docs https://webpack.js.org/api/loaders/#thishot
we can know if HMR is enabled during
COMPILE PHASE.The current code increase unnecessary codes in production. ( Hot Module Reload is never enabled in production)
Hope this little change may help generating smaller output codes.
I also found that
refsvariable is never used, so it could be removed safely.
