Golang gin framework using 80,443 pory

I have one application which is deployed on iis server. It is using port 80,443.

How I can deploy golang gin on same Port

You would use gin package - github.com/gin-gonic/gin - Go Packages, but the OS won’t let multiple processes listen on the same port on the same IP address. Maybe you want to front both apps with a reverse proxy.

I would like to run angular and golang on same server and same Port .

How to achieve this

You would have to build your Angular app then have your Go API serve it up as static content. Check out http/FileServer.
