javascript - Cross domain issues, HTTP requests with different ports -

i made client-side web application fun , try integrate server-side stuff.

using brunch starter client , gulp start server.

i not sure how send requests client when have different ports. cross domain request issues. googled still have no clue.

different ports treated different domains, xhr cross-domain rules apply. set server-side pass xhr requests using proper headers: how enable cross-domain request on server?

another way prepare cross-domain proxy forward requests wuthout editing server code, e.g.:
