Rethinking the extensions framework in Magento

• Efficient, secure, easy to use

• Focus: Upgradability and Compatibility

• We are introducing new concepts and gathering feedback to

refine the ideas

Services

• Encapsulates the access to the business logic

• Provides access to the data needed in templates

• Have well defined interfaces, which allows exposing the

logic via API

• Keeps access to business logic consistent for all clients:

SOAP, internal, etc

Twig templates

• Template is populated with data

• Restricts view layer from complex business logic and data

access scenarios

• Focused on data rendering

• Development of templates become easier without risk of

changing the business logic

• Allows building a secure view layer

• Automatic output encoding

• Magento provides custom functions and filters to access the

layout functionality within a template

No more SQL queries in Templates!

Presentation tier Business logic

Define the service call configuration

Make a reference to the service call from the layout

Display service data in the Twig

Data from service call can be used in layout

Blocks encapsulation

• Just generic blocks are needed

• Each block has its own data

• Parent block doesn’t share data with child

• Layout elements can be easily repositioned

Configurable dropdown options

• via service call

• via constants

• via configuration

Service?

• Interface to Business logic

• PHP Code

• Remote Endpoint

IDL will be a combination

of PHP annotations

and external schemas

The PHP function receives an

associative array reflecting the

structure described by the annotation

– Eliminates need for polling

– Supports real-time data integrations

– Asynchronous

Webhook Config

Webhook Listener

Parsing Event Data

Extension points where callback

results influence Magento behavior

(synchronous)

Callback Extension Points

• Define your shipping config

• Use the provided callback service

Shipping Extension Config

What was that <subscriber> tag all about?

Callback Subscriber

Shipping Endpoint

Input defined in the IDL

{

"shippingMethods": [

{

"carrier": “acme",

"carrierTitle": “ACME Shipping",

"method": "ground",

"methodTitle": “ACME Ground",

"price": 3.75

}

]

}

It Works!
