Ability to serve base page without trailing slash?

[Norlandz]

I have a webpage with base name, say:
http://localhost:5173/app

I config vite to have base: '/app/'

I have to access it in http://localhost:5173/app/
If I try to access http://localhost:5173/app, it forces me to go to http://localhost:5173/app/.
(When its deployed to Nginx / served by expressjs.)

I tried config vite to have base: '/app', problem persists.

How can I remove that trailing slash?
