Getting "Router is not defined" error?

[Broham]

I am attempting to create a server side route inside of a file /server/routes.coffee using the following code:

Router.route("/revision", {where: "server"})
.get ->
  console.log "revision route...."
  ...

But when I start my app I get the following error:

W20170127-09:19:46.164(-8)? (STDERR) ReferenceError: Router is not defined

When I do meteor list I see:

iron:router 1.1.1 Routing specifically designed for Meteor

(along with many other packages)

Can anyone see why I would be getting this error?
