3000 and a web app at port 4200, which is working fine. Unfortunately I am encountering some problems that aren't described anywhere in their documentation (as far as I can tell)./about page, then it will obviously navigate to localhost:3000/blog/about instead of localhost:3000/about. One solution is to check the base path in the navigation component and then prepend localhost:3000 to the href if the base path equals blog, but that refreshes the entire app and does not result in smooth navigation, so it's not really ideal. Is there anything else can I do about this?
