The document outlines essential aspects of Magento 2, covering configuration, dependency injection, event management, service contracts, and web API creation. It includes code snippets and examples related to class definitions, service interfaces, and UI components. Additionally, it discusses features such as page caching, asynchronous processing, and themes, aimed at enhancing development and user experience.

4. Communication &
Documentation
☞ github.com/magento/
magento2
☞ devdocs.magento.com
☞ community.magento.com
☞ alankent.me

5. $ composer install

6. Console Application
$ bin/magento setup:upgrade

7. Configuration
☞ Configuration file per sub-system (events.xml, cache.xml)
☞ All xml validated
☞ 3 Stages of configuration loading:
➀ primary (app/etc/*)
➁ global (<ModuleDir>/etc/*)
➂ area (<ModuleDir>/etc/<areaCode>/*)

8. Dependency Injection
class MyClass
{
public function __construct(MagentoFrameworkEventManager $eventManager)
{
$this->eventManager = $eventManager;
}
public function someFunc()
{
// …
$this->eventManager->dispatch(‘some_event’);
// …
}
}

9. Interception
Ability to observe public method calls:
class eventManagerPlugin
{
public function beforeDispatch(EventManager $subject, $eventName, $arguments)
{
$this->log->put(“Event ‘$eventName’ was dispatched“);
}
}

10. Service Contracts
Public API of a module:
namespace MagentoCustomerApi;
interface AccountManagementInterface
{
public function createAccount(CustomerInterface $customer, $password = null);
public function activate($email, $confirmationKey);
public function changePassword($email, $currentPassword, $newPassword);
}

11. WebAPI
Easy WebAPI creation (REST & SOAP)
<routes>
<route url="/V1/customerGroups/:id" method="GET">
<service class="MagentoCustomerApiGroupRepositoryInterface" method="getById"/>
<resources>
<resource ref="Magento_Customer::group"/>
</resources>
</route>
</routes>

12. Themes
☞ More granular templates
☞ View file fallback
☞ LESS imports

13. UI Library

14. RequireJS Loader
define(
[
'Magento_Checkout/js/model/address-converter'
],
function(addressConverter) {
"use strict";
return function(addressData) {
return addressConverter.formAddressDataToQuoteAddress(addressData);
};
}
);

15. JS Mixins
var config = {
mixins: {
‘Magento_Checkout/js/model/address-converter’: {
‘My_Module/js/model/address-converter-mixin’: true
}
}
};

16. UI Components
☞ JS & CSS & HTML
☞ New forms & grids in admin and storefront

17. PageCache
☞ built-in cache in CE
☞ Varnish support in CE
☞ Private content rendered in browser

18. Asynchronous processing
☞ delayed execution
☞ ee-only
