Building custom directives on AngularJS pages without a specified ng-app module

Question

Building custom directives on AngularJS pages without a specified ng-app module

On some of my basic pages, I don't need to specify a particular application module in the ng-app attribute. However, these pages do utilize some custom directives that I have created.

To keep things organized, I have placed all of my directives within a separate namespace (or module) called MyApp.Directives.

This setup works well when I provide my application module, as I can add MyApp.Directives as a dependency and everything functions smoothly.

angular.module("MyApp", ["MyApp.Directives", ...])

However, I also have some very simple pages that do not require a specific application module because they only use standard Angular directives like ng-....

Question

I am aware that I can add all of my custom directives to the ng module so that they are accessible on all pages, regardless of whether they have a custom application module or not. But this goes against the modular structure that I aim for in my application. Is there a way for me to inform the dependency injector about my additional directives/filters without adding them directly to the ng module?

I want to avoid cluttering my codebase with unnecessary code to maintain the simplicity and manageability of my application (which is a core principle of AngularJS). Essentially, I am looking for a clever workaround that would make the ng module recognize my directives without actually including them in it... This question delves into more advanced aspects of Angular development, potentially involving some behind-the-scenes manipulation.

I have attempted manually adding my directives' module to the angular.module("ng").requires array, but unfortunately, that did not produce the desired outcome.

#1) To utilize only one module, you can simply use `ngApp`:

<html ng-app="MyApp.Directives">

#2) When dealing with multiple modules, make use of `angular.bootstrap` in this manner:

angular.element(document).ready(function(){
  angular.bootstrap(document,['MyApp.Directives','MyApp.Filters']);
});

#3) Alternatively, you can create a basic module for defining dependencies:

<html ng-app="myApp">

......

<script>
  angular.module('myApp',['MyApp.Directives','MyApp.Filters']);
</script>

If we had the ability to write something like this:

<html ng-app="MyApp.Directives  MyApp.Filters">

I implemented a fix in the source code:

function angularInit(element, bootstrap) {

// some code

  if (appElement) {
    bootstrap(appElement, module ? module.split(/\s+/) : []); // split by spaces :)
  }
}
