dollar-inject

$inject = require('dollar-inject')

sessionController = $inject 'session', '$http',
  (session, $http) ->
    ...

basically does

function sessionController (session, $http) {}
sessionController.$inject = ['session', '$http']

Why?

Because we're still using coffee-script

And the bracket notation is a bit annoying sometimes:

sessionController = ['session', '$http', (session, $http) ->
    ...
