Laravel has a powerful Inversion of Control (IoC) / Dependency Injection (DI) Container. Unfortunately the official documentation doesn't cover all of the available functionality, so I decided to experiment with it and document it for myself. The following is based on Laravel 5.4.26 - other versions may vary.
I won't attempt to explain the principles behind DI / IoC here - if you're not familiar with them you might want to read What is Dependency Injection? by Fabien Potencier (creator of the Symfony framework).
<?php | |
namespace Deployer; | |
require 'recipe/laravel.php'; | |
// Configuration | |
set('ssh_type', 'native'); | |
set('ssh_multiplexing', true); | |
set('git_tty', true); // [Optional] Allocate tty for git on first deployment |
Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.
