Write down your doubts

What are we going to do

Create a Laravel application using modern methodologies:
 

  • TDD

  • Continuous Integration

  • Clean Code

  • Domain Driven Design

  • Hexagonal Architecture

How the workshop will be held

We are going to create an application with Laravel 5.x, using the framework as a tool.


During this journey, we'll discuss and learn all the topics we introduced to you.
 

There will be practical, theoretical and brainstorming sessions.

PHP

Evolution over time

The beginning

  • Born in 1994 as a set of “commands” written in C by Rasmus Lerdorf
     
  • Originally used for tracking visits on his websites
     
  • The name comes from “Personal Home Page Tools”
     
  • Over time, the project grows and new features were introduced
     
  • In 1995 the project becomes open source

Composer

A tool for
dependency management in PHP

PSR0 & PSR4

No, namespaces in PHP are not magic.

It's still plain PHP.

return \spl_autoload_register([$this, 'loadClass'], true, $prepend);

Scripts

They are functionality called before/after some actions

...
"scripts": {
   "post-root-package-install": [
       "@php -r \"file_exists('.env') || copy('.env.example', '.env');\""
   ],
   "post-create-project-cmd": [
       "@php artisan key:generate"
   ],
   "post-autoload-dump": [
       "Illuminate\\Foundation\\ComposerScripts::postAutoloadDump",
       "@php artisan package:discover"
   ]
},

Brainstorming

Laravel, it's a tool.

The domain, it's not a tool!

Value objects

It's an immutable object representing a value in a domain.
 

It's comparable to other value objects by its own values.

Entities

It's a mutable object with an identity, it can be represented in different ways.

 

It's comparable to other entities by its ID.

  

Repositories

It's an abstraction layer to provide access to all the entities and the value objects related to an aggregate.

Services

It's an object to use to manipulate entities and value objects when the logic doesn't fit or distort their integrity.

Not to be confused with the application or infrastructure services.

Events

It's an immutable object used to represent something important that occurred in the domain.
