Only incorporate the Angular service into the controller when it is necessary

When attempting to incorporate lazy loading for angular services, controllers, directives, and filters, I discovered a way to achieve something similar using RequireJS. However, I am struggling to find a way to dynamically load a service into a controller only when it is actually needed.

Here is an example of my current controller setup:

require(["app"], function (app) {

  app.controller('dialogsCtrl',function($scope,dialogsSer){
    $scope.tooltip = function(){
      dialogsSer.tooltip(); // works fine
    }
...

What I would like to achieve (while still being able to inject the service in Angular's inline way) is this:

require(["app"], function (app) {

  app.controller('dialogsCtrl',function($scope){ 
    $scope.tooltip = function(){
      // load the service only when the tooltip function is called
      require(["dialogsSer"], function (dialogsSer){
         dialogsSer.tooltip();  
      );
    }
...

My RequireJS configuration setup looks like this:

require.config({
baseUrl: ...,    
paths: {
    ....
    'dialogService':'resources/web/app/services/dialogsSer',
     ...
deps: ['app']
});

And here is how the Dialogs service is defined:

require(["app","directives"], function (app) {

  app.service('dialogsSer', function($http,$uibModal){

  var ds = {};
  ...

Answer №1

I discovered the angular $injector method to dynamically insert services at runtime.

require(['dialogService','userService'], function(){
     if(!$rootScope.userService) $rootScope.userService = $injector.get("userService");
     if(!$rootScope.dialogsService) $rootScope.dialogsService = $injector.get("dialogsService");
     $scope.$apply(); 
});
