How to safely use a “catch all” in production mode?

Question

Play Framework has the file routes. This file list all the routes needed by the application. By default, the route file has a line:

# Catch all
*       /{controller}/{action}                  {controller}.{action}

How to safely use it in production mode? Do I need to comment this line out?

Answer 1

Yes, ideally you should comment it in production. In fact I would comment it in development too, that way you'll notice any missing route.

Answer 2

If you still want to use it in dev (for faster development, nice error messages, ...), this is how you do it:

#{if play.mode.isDev()}
  *   /{controller}/{action}      {controller}.{action}
#{/if}
