HMR stopped working with RC10

Describe the bug
Hot reloading stopped working with rc10

I have the same issue, but changing it to rc9 still doesnt fix it. Is it because i use electron v2?

This appears to be related to an existing issue with webpack-dev-server.

This is what worked for me. Starting from the beginning:

1. vue create your-electron-vue-project
2. cd your-electron-vue-project
3. vue add electron-builder
4. add a vue.config.js at the root directory of the project. This allows you to configure webpack (read Vue cli docs)
5. inside the vue.config.js
   module.exports = { devServer: { headers: { "Access-Control-Allow-Origin": "*" }, https: false, disableHostCheck: true } };
6. npm run electron:serve

Everything should work fine. Should this not work for you and you find another way, kindly share here.

Happy holidays!

Closing as the issue is related to another package. Thanks for posting a solution!
