AngularJS – Get List of All Registered Services?

You can get a list of the providers (ie services/directives/controllers/factories/etc) for each module, although the list is kind of cryptic.

Say you have the following:

var mod = angular.module('myModule', []);
mod.factory('fact1', function($dependency1, $dependency2){ ... });
mod.service('serv1', function($dependency3, $dependency4){ ... });
mod.controller('ctrl1', function($dependency2, $dependency3){ ... });
mod.factory('fact2', function($dependency1, $dependency4){ ... });
...

Then the mod variable will contain an attribute called mod._invokeQueue that will contain an array of all the providers that are part of that module. The _invokeQueue will look something like this:

[
    ['$provide', 'factory', Arguments['fact1', ['$dependency1', '$dependency2', function(){}],
    ['$provide', 'service', Arguments['serv1', ['$dependency3', '$dependency4', function(){}],
    ['$provide', 'controller', Arguments['ctrl1', ['$dependency2', '$dependency3', function(){}],
    ['$provide', 'factory', Arguments['fact2', ['$dependency1', '$dependency4', function(){}]
    ...
]

So you can search through that mod._invokeQueue for each provider that it contains.

But that will only contain the list of providers for that specific module. If you want to get a list of all of the dependent modules, you will need to loop through the mod.requires array.

If the module has module-level dependencies, like so:

var mod = angular.module('myModule', ['otherModule1','otherModule2']);

Then the mod object will also have a mod.requires array that contains the names of those module dependencies, like so:

angular.forEach(mod.requires, function(requiredModuleName){
    // first get a reference to the required module by calling angular.module()
    var requiredMod = angular.module(requiredModuleName);
    // requiredMod will have its own ._invokeQueue
    // requiredMod._invokeQueue will look like the _invokeQueue from above
    ...
    // do something with the additional providers in _invokeQueue
});
