Methods

• provider(name, provider);

  Register a provider function with the $injector. Provider functions are constructor functions, whose instances are responsible for "providing" a factory for a service.

  Service provider names start with the name of the service they provide followed by Provider. For example, the $log service has a provider called $logProvider.

  Service provider objects can have additional methods which allow configuration of the provider and its service. Importantly, you can configure what kind of service is created by the $get method, or how that service will act. For example, the $logProvider has a method debugEnabled which lets you specify whether the $log service will log debug messages to the console or not.

  Parameters

  Param	Type	Details
  name	string	The name of the instance. NOTE: the provider will be available under name + 'Provider' key.
  provider	Objectfunction()	If the provider is: Object: then it should have a $get method. The $get method will be invoked using $injector.invoke() when an instance needs to be created. Constructor: a new instance of the provider will be created using $injector.instantiate(), then treated as object.

  Returns

  Object

  registered provider instance

• factory(name, $getFn);

  Register a service factory, which will be called to return the service instance. This is short for registering a service where its provider consists of only a $get property, which is the given service factory function. You should use $provide.factory(getFn) if you do not need to configure your service in a provider.

  Parameters

  Param	Type	Details
  name	string	The name of the instance.
  $getFn	function()Array.<(string|function())>	The injectable $getFn for the instance creation. Internally this is a short hand for $provide.provider(name, {$get: $getFn}).

  Returns

  Object

  registered provider instance

• service(name, constructor);

  Register a service constructor, which will be invoked with new to create the service instance. This is short for registering a service where its provider's $get property is a factory function that returns an instance instantiated by the injector from the service constructor function.

  Internally it looks a bit like this:

  {
    $get: function() {
      return $injector.instantiate(constructor);
    }
  }
  

  You should use $provide.service(class) if you define your service as a type/class.

  Parameters

  Param	Type	Details
  name	string	The name of the instance.
  constructor	function()Array.<(string|function())>	An injectable class (constructor function) that will be instantiated.

  Returns

  Object

  registered provider instance

• value(name, value);

  Register a value service with the $injector, such as a string, a number, an array, an object or a function. This is short for registering a service where its provider's $get property is a factory function that takes no arguments and returns the value service. That also means it is not possible to inject other services into a value service.

  Value services are similar to constant services, except that they cannot be injected into a module configuration function (see angular.Module) but they can be overridden by an Angular decorator.

  Parameters

  Param	Type	Details
  name	string	The name of the instance.
  value	*	The value.

  Returns

  Object

  registered provider instance

• constant(name, value);

  Register a constant service with the $injector, such as a string, a number, an array, an object or a function. Like the value, it is not possible to inject other services into a constant.

  But unlike value, a constant can be injected into a module configuration function (see angular.Module) and it cannot be overridden by an Angular decorator.

  Parameters

  Param	Type	Details
  name	string	The name of the constant.
  value	*	The constant value.

  Returns

  Object

  registered instance

• decorator(name, decorator);

  Register a service decorator with the $injector. A service decorator intercepts the creation of a service, allowing it to override or modify the behavior of the service. The object returned by the decorator may be the original service, or a new service object which replaces or wraps and delegates to the original service.

  Parameters

  Param	Type	Details
  name	string	The name of the service to decorate.
  decorator	function()Array.<(string|function())>	This function will be invoked when the service needs to be instantiated and should return the decorated service instance. The function is called using the injector.invoke method and is therefore fully injectable. Local injection arguments: $delegate - The original service instance, which can be monkey patched, configured, decorated or delegated to.
