I have 2 pages (I don't use the angular's routing - This constraint).

In one of them I want to use the directive ui-grid like in this demo:

var app = angular.module('myApp', ['ui.grid']);
app.controller('mainCtrl', function($scope) {
  $scope.myData = [
    {
        "firstName": "Cox",
        "lastName": "Carney",
        "pany": "Enormo",
        "employed": true
    },
    {
        "firstName": "Lorraine",
        "lastName": "Wise",
        "pany": "Comveyer",
        "employed": false
    },
    {
        "firstName": "Nancy",
        "lastName": "Waters",
        "pany": "Fuelton",
        "employed": false
    }
  ];
});

<script src=".2.26/angular.js"></script>
<script src=".js"></script>
<link rel="stylesheet" href=".css" type="text/css">

<div ng-app="myApp">
  <div ng-controller="mainCtrl">
    <div id="grid1" ui-grid="{ data: myData }" class="grid"></div>
  </div>
</div>

<div ng-app="myApp">
  <div ng-controller="mainCtrl">
    <div id="grid1" ui-grid="{ data: myData }" class="grid"></div>
  </div>
</div>

My question is if there is a way to not inject the ui-grid dependency to the app in any case but only when I need it.

Something like:

app.controller('mainCtrl', function($scope) {
   app.$inject('ui-grid');
});

Update

I tried to do:

var ui_grid = $injector.get('ui-grid');

But I've got an error:

Unknown provider: ui-gridProvider <- ui-grid

• @AT no it's not. My question is about using another module and his directives in the view not in the controller. – Mosh Feu Commented Dec 17, 2015 at 8:26
• I assume also a dupe of stackoverflow./questions/29617903/… & stackoverflow./questions/27721530/…. In Mosh’s case it’s a directive not a service – Anton Strogonoff Commented Dec 17, 2015 at 8:36
• @AntonStrogonoff No, it's not. Did you see my ment to A T? It's the same. I don't need to inject a service or factory. I need to inject a module. Can you share with me a working fiddle with solution like in your attached question? – Mosh Feu Commented Dec 17, 2015 at 8:39
• @MoshFeu I don’t think injector would help you with modules indeed, can’t help here. Note that in your second code block example you’re showing how you want to inject a directive, not a module. It’s in general confusing as to what is the goal that you’re trying to achieve. – Anton Strogonoff Commented Dec 17, 2015 at 8:53

Core Angular API does not provide this feature. ocLazyLoad is the popular library for lazy loading of modules and ponents in Angular.

You can find more info on their page: https://oclazyload.readme.io

or the GitHub repository: https://github./obe/ocLazyLoad

Core Angular API does provide this feature, simply use 'requires' property of module @ Properties section @ https://code.angularjs/1.4.7/docs/api/ng/type/angular.Module

var app = angular.module('myApp');

//Page 1 JS
//change below statement as per requirement in different pages
app.requires = ['ui.grid'];
app.controller('mainCtrl1', function($scope) {

}

//Page 2 JS
app.requires = ['ngResource', 'ui.bootstrap', 'ui.calendar'];
app.controller('mainCtrl2', function($scope) {

}

ocLazyLoad is also good solution, but I guess 'requires' property will solve your problem without much effort.

In my project I dynamically bootstrap angular modules using angular.bootstrap(). I have several pages with different sets of modules.

Example:

var app = angular.module('demo', [])
.controller('WeleController', function($scope) {
  $scope.greeting = 'Wele!';
});
angular.bootstrap(document, ['demo']);

<script src="https://ajax.googleapis./ajax/libs/angularjs/1.2.23/angular.min.js"></script>

<div ng-controller="WeleController">
  {{greeting}}
</div>

$injector is used to retrieve object instances as defined by provider, instantiate types, invoke methods, and load modules.

var $http = $injector.get('$http');

To plete your use-case:

app.controller('mainCtrl', function($scope, $injector) {
    $scope.myData = [];
    if($scope.loadGrid) {
        var ui_grid = $injector.get('ui-grid');
        ui_grid.load($scope.myData); //`.load` is just a guess, obviously read your docs
    }
});

For more information see:

• https://docs.angularjs/api/auto/service/$injector
• https://github./angular/angular.js/wiki/Understanding-Dependency-Injection

In a angularJS for injecting module you should inject it after your module name as you did.

But you have few steps to can use it:

1. Install it with this 2 way npm or bower like below:

   npm install angular-ui-grid

   bower install angular-ui-grid

2. Then add a <script> to your index.html:

   <link rel="stylesheet" type="text/css"href="/bower_ponents/angularui-grid/ui-grid.css" />
   <script src="/bower_ponents/angular-ui-grid/ui-grid.js"></script>
   

   • If you use npm, you should change the source path to/node_modules/.

After this steps each module you can have access to you module like below:

angular.module('my.module', ['ui.grid']).
