lazyLoad module for angularjs
In order to add dynamic loading of modules for angularjs, then you need to:

1. to find the line:
   forEach(loadModules(modulesToLoad), function(fn) { instanceInjector.invoke(fn || noop); });
2. replace it with:
   instanceInjector.injectModules = function (_modulesToLoad){ forEach(loadModules(_modulesToLoad), function(fn) { instanceInjector.invoke(fn || noop); }); };
instanceInjector.injectModules(modulesToLoad);
3. upload files with the modules in any way possible (eg requirejs) and call a method injectModules in service $injector

If you add this code:
//angular patch fro get modules. ensure(angular, 'modules', function(){ return modules; });
in:
return ensure(angular, 'module', function() { /** @type {Object.<string, angular.Module>} */ var modules = {};

You can write modules to add to the current application:
example code:
var _aBeforeInject = angular.extend({}, angular.modules), _aInjectModules = []; //... //You load modules code //... angular.forEach(angular.modules, function(value, key){ if (!_aBeforeInject.hasOwnProperty(key)){ _aInjectModules.push(key); } }); //inject new modules $injector.injectModules(_aInjectModules);

enjoy. =)
