Negative regex matches

[stevenmusumeche]

I'm trying to match a catch-all route which matches all paths except those that end with .ico. The regular expression for this is straightforward:

.add(`/:path(?!.*ico)`, 'static-content')

however, I get the following error, because the exclamation point is being escaped.

SyntaxError: Invalid regular expression: /^\/(?\!.*ico)(?:\/)?$/: Invalid group

@stevenmusumeche, hey is there any workaround?
