You can just treat $http.get() as a promise. You don't have to directly
instantiate a second promise unless you're doing something funky.
return $http.get().then(function(data){return
massageData(data)}).catch(function(err){at least you have some error
handling})
Also, if you're getting an error, what's the failed? At the very least, I'm
99.9% sure that http://localhost:/localfile.txt is an incorrect url. Don't
you have to put a port after a : in a host definition? so either
localhost/localfile or localhost:3000/localfile. So it could be that your
$http.get is just failing. You can get more information on this in the
chrome debug tools - look at your network requests, and it should show the
localfile.txt XHR, and either be black (success!) or red (fails!) and have
more information there.
