angular.module (API in module ng )

The angular.module is a global place for creating and registering Angular modules. All modules (angular core or 3rd party) that should be available to an application must be registered using this mechanism.

Module

A module is a collocation of services, directives, filters, and configuration information. Module is used to configure the $injector.

// Create a new module
var myModule = angular.module('myModule', []);

// register a new service
myModule.value('appName', 'MyCoolApp');

// configure existing services inside initialization blocks.
myModule.config(function($locationProvider) {
  // Configure existing providers
  $locationProvider.hashPrefix('!');
});

Then you can create an injector and load your modules like this:

var injector = angular.injector(['ng', 'MyModule'])

However it's more likely that you'll just use ngApp or angular.bootstrap to simplify this process for you.

angular.module(name[, requires], configFn);
