Should Webpacker "support" hot module reloading?

For a long discussion on this topic, see: Hot Module Reloading #332.

Maybe this HMR will be stable eventually.

We support this feature for React on Rails via examples, but not as a core part of the gem. By this, I mean that we do not add the extra complexity of HMR. In retrospect, this was a great decision.

@justin808 I don't think webpacker provides this out-of-the-box? It does provide webpack-dev-server support, but not with --hot option. Perhaps, something to clear out in the readme.

Am I missing something here?

Because this should be already supported because of webpack-dev-server?

Must it be explicitly supported for React? For Vue, it comes out of the box whenever i switch on webpack-dev-server.

We can close this. Webpack dev server is hot reloading and the ability to have the asset helpers use a different port is money.
