Regex match for optional trailing slash

Question

I'm trying to match:

/app
/app/
/app/**

but not:

/app**

The trailing slash should be optional. I can't quite get it to work.

^/app/([^/]*)/? matches /app/ and /app/**, but not /app.

Answer 1

Try this:

^\/app((\/\w+)+|\/?)$

Answer 2

This will work:

^/app(/[^/]*)?

edit: This will also work:

^/app(/.*)?
