Best Practices for Implementing AngularJS Dependency Injection

I am excited to share that I have recently started delving into my very first Angular JS project. As I navigate through this new experience, I want to ensure that I am effectively managing Multiple dependency injection. Any insights, recommendations, or feedback you may have would be immensely valuable!

var app = angular.module('app', [
  'ngRoute',
  'ngIdle',
  'ui.bootstrap'
]);

app.controller('testCtrl', [
  '$scope', '$http', '$timeout', '$location', 'SessionService',
  function($scope, $http, $timeout, $location, SessionService) {

  // Implement functionality here
}]);

Answer №1

When it comes to syntax, there are a variety of ways to handle it:

MyAppModule.controller("MyCtrl",MyCtrl);
MyCtrl.$inject = ['$scope', '$http', '$timeout', '$location', 'SessionService'];
function MyCtrl($scope, $http, $timeout, $location, SessionService){
    //..do stuff
}

I personally prefer this method because it allows for easy separation from Angular and can be enclosed in a !function(){}() to prevent global exposure. It also requires minimal effort for injector initialization.

Another option is the array syntax you have displayed, which may appeal to those who like brackets (}])).

An alternative approach is to use a build tool like ngmin to avoid manually typing string names. However, you must adhere to dependency declaration guidelines.

There isn't necessarily a set of best practices for these methods; it ultimately comes down to personal preference.
