How to deploy app to sub-directory

[jaichandra]

How can I deploy an app using app-router to a subdirectory? The routes are mapped to root directory by default and works fine when using localhost. But, deploying the app to a subdirectory fails to load as the routes no more work.

@jaichandra Do you have a jsbin somewhere I can take a look at? What's your path regex like?
