How to Best Handle Dependency Injection in AngularJS for Minification?

Identifying the Dependency Injection Best Practice for Minifying AngularJS Applications

Within the context of AngularJS dependency injection, it has been noted that the minification process can lead to potential issues. To address this, we explore the two available options for dependency injection in AngularJS:

Option 1 (Standard Method):

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

Option 2 (Inject Method):

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
    })
}]

Recommended Best Practice:

While it was initially believed that the Standard Method was reserved for older versions of AngularJS, the documentation clearly states that the Inject Method should be used always for minification purposes. This preference is made because:

• The Inject Method ensures that the identity of minified function arguments ($scope and $http) is preserved in string form, even if they are replaced with shorter variable names.

Alternative: ng-annotate NPM Package

As an alternative to the verbose Inject Method, developers may opt to leverage the ng-annotate NPM package during the build process. This tool automatically adds annotations to AngularJS controllers, allowing for minification without the need for explicit injection arrays.
