Proxy exact paths to express

Split from #17

Could you tell me what is your browser please? Did you try on another one?

I know that there are some recent issues with the webpack proxy, and Firefox.

For me it's the same that facebook/create-react-app#6720, due to https://bugzilla.mozilla.org/show_bug.cgi?id=1536843.

In all cases, the proxy service and the HMR one are not part of this package, which is simply passing theses parameters in vue-cli services, so we should not merge theses specific modifications in here 😕.

Can you disable the proxy in the package, and try to enable it directly by following instructions here: https://cli.vuejs.org/config/#devserver-proxy and tell me if it's different?

I am having a difficult time understanding how this is related to #6720 above. The issue exists due the fact that the original proxy configuration was proxying all requests from devServer to the express server.

I followed the instructions at https://cli.vuejs.org/config/#devserver-proxy to create the proxyConfig object to selectively proxy only the requests that should be sent to express.

Looking back #17 the first image shows the devServer proxy error /sockjs-node this is because the express server is not serving a /sockjs-node route.

Original
Frontend --> devServer -(proxy: *)-> express
With PR
Frontend --> devServer -(proxy: /socket.io, proxy: /bar, ...)-> express
