Class RegistryProxyMixin

Check if a factory is registered.

Registers a factory that can be used for dependency injection (with inject) or for service lookup. Each factory is registered with a full name including two parts: type:name.

A simple example:

import Application from '@ember/application';
import EmberObject from '@ember/object';

let App = Application.create();

App.Orange = EmberObject.extend();
App.register('fruit:favorite', App.Orange);

Ember will resolve factories from the App namespace automatically. For example App.CarsController will be discovered and returned if an application requests controller:cars.

An example of registering a controller with a non-standard name:

import Application from '@ember/application';
import Controller from '@ember/controller';

let App = Application.create();
let Session = Controller.extend();

App.register('controller:session', Session);

// The Session controller can now be treated like a normal controller,
// despite its non-standard name.
App.ApplicationController = Controller.extend({
  needs: ['session']
});

Registered factories are instantiated by having create called on them. Additionally they are singletons, each time they are looked up they return the same instance.

Some examples modifying that default behavior:

import Application from '@ember/application';
import EmberObject from '@ember/object';

let App = Application.create();

App.Person = EmberObject.extend();
App.Orange = EmberObject.extend();
App.Email = EmberObject.extend();
App.session = EmberObject.create();

App.register('model:user', App.Person, { singleton: false });
App.register('fruit:favorite', App.Orange);
App.register('communication:main', App.Email, { singleton: false });
App.register('session', App.session, { instantiate: false });

Register options for a particular factory.

Allow registering options for all factories of a type.

import Application from '@ember/application';

let App = Application.create();
let appInstance = App.buildInstance();

// if all of type `connection` must not be singletons
appInstance.registerOptionsForType('connection', { singleton: false });

appInstance.register('connection:twitter', TwitterConnection);
appInstance.register('connection:facebook', FacebookConnection);

let twitter = appInstance.lookup('connection:twitter');
let twitter2 = appInstance.lookup('connection:twitter');

twitter === twitter2; // => false

let facebook = appInstance.lookup('connection:facebook');
let facebook2 = appInstance.lookup('connection:facebook');

facebook === facebook2; // => false

Return a specific registered option for a particular factory.

Return registered options for a particular factory.

Return the registered options for all factories of a type.

Given a fullName return the corresponding factory.

Unregister a factory.

import Application from '@ember/application';
import EmberObject from '@ember/object';

let App = Application.create();
let User = EmberObject.extend();
App.register('model:user', User);

App.resolveRegistration('model:user').create() instanceof User //=> true

App.unregister('model:user')
App.resolveRegistration('model:user') === undefined //=> true
