Configuring public path for hot middleware reload

[beku8]

We are trying to use nextjs for certain parts of our app. So I have a proxy app running on http://localhost:8080, which will dispatch certain requests to nextjs app running on http://localhost:3000. For production environment, hopefully, it will work fine with assetPrefix: 'http://{production_url}', but for development the following requests are being made for hot module replacement:

• /_next/webpack-hmr
  - /_next/on-demand-entries-ping?page=/

which are apparently configured as a relative path, so when I access thru my proxy, it will try to access at http://localhost:8080/_next/on-demand-entries-ping?page=/ from the browser.

Is there any possible way to override the path to explicitly define to fetch from http://localhost:3000?

I tried to replicate it and my /_next/on-demand-entries-ping?page=/ and /_next/webpack-hmr both goes to the correct port. Could you provide a repository to replicate it?

Will be fixed when #2901 lands 👍
