Since the early days of Magento, the PHP eCommerce platform has taken the world by storm. As with any new platform, there were growing pains. Five years later, we see the age of Magento 2 dawning upon us. Although not rewritten from the ground up, the architects behind the beast went back to the drawing board to create something innovative. This led to a system with configurable dependency injection, PSR compliance, decoupled modules, native composer support, and a modern tech stack. This talk looks at some ways Magento has improved. You will also learn how to create a plugin in Magento 2.

Magento 2: Installing for Development
Vagrant managed virtual machines
Docker images per-site and/or service
Zend Server also works

VagrantVirtual Machines
Fully encapsulated environment
Very simple to use
Easily maintained / updated
OneVM for everything down to one per-site basis

26. Magento 2: New and Innovative? @blackbooker / #phpworld
Vagrant Stack
Runs single environment for all sites in development
Two machines: one for database, one for application
Defaults to PHP 5.6 / MySql 5.6
Supports PHP back to 5.3 and MySql 5.1 via alt nodes
Works withVirtualBox orVMWare Fusion
Currently only tested on OS X

Docker Images
Cross-platform… but still needVM on non-Linux
Flexible and powerful for complex deploy scenarios
Ensure dev matches prod env 100% on a per-site basis
Major downfall? Complexity = steep learning curve

MageInferno Images
Single responsibility images
Docker compose for easier daily use
Built on top of Dinghy by CodeKitchen

31. Magento 2: New and Innovative? @blackbooker / #phpworld
Single Use Docker Image
Provided by the Magento team
Really only for development use
Single image for all services
Run one instance per-site
Simple, but doesn't really utilize full power of docker

Plugins
Amazingly simple…
32

33. Magento 2: New and Innovative? @blackbooker / #phpworld
Plugins
Plugins work using technique called interception
They are implemented in context of a module
You write your plugins; interceptor code is generated
