groute
If you are sick of the time it takes to run rake routes
every time you want to inspect your routes or search for a particular one, check out this gem that my friend Jordan Carter wrote called groute.
It caches your routes in a temporary file so that subsequent searches are lightning fast, and only regenerates the routes when they change.
Usage
Install the gem:
$ gem install groute
and use it like this:
$ groute products
which is the same as doing:
$ rake routes | grep products
but way faster!
