Angularjs minify best practice

Question

I'm reading http://www.alexrothenberg.com/2013/02/11/the-magic-behind-angularjs-dependency-injection.html and it turned out that angularjs dependency injection has problems if you minify your javascript so I'm wondering if instead of

var MyController = function($scope, $http) {
    $http.get('https://api.github.com/repos/angular/angular.js/commits')
      .then(function(response) {
        $scope.commits = response.data
      })
  }

you should use

var MyController = ['$scope', '$http', function($scope, $http) {
  $http.get('https://api.github.com/repos/angular/angular.js/commits')
    .then(function(response) {
      $scope.commits = response.data
    })
}]

all in all I thought the second snippet was for the old version of angularjs but ....

Should I always use the inject way (the second one) ?

Answer 1

Yes, always! So this way even if your minifer converts $scope to variable a and $http to variable b, their identity is still preserved in the strings.

See this page of AngularJS docs, scroll down to A Note on Minification.

UPDATE

Alternatively, you can use ng-annotate npm package in your build process to avoid this verbosity.
