What are we going to do
Create a Laravel application using modern methodologies:
-
Continuous Integration
-
Clean Code
-
Domain Driven Design
-
Hexagonal Architecture
How the workshop will be held
We are going to create an application with Laravel 6.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.
