Problems

IRL projects, it is inevitable for PRs that contains a lot of changes (thousands of lines, 50+ files).

For those PRs, even you have 10 people to review, they still won't cover everything 100%. Simply because it is too much.

Everybody loves small PRs and that is the undeniable fact. But how can we achieve it?

Welcome to DevFlag!

Solutions

DevFlag will help you to achieve that. Not only the tool, but also require a bit of your critical thinking.

Before starting development, you need to ensure:

  • The scope, the changes that you will do (aka Technical Breakdown)
    • This is the most important phase, you need to finalize the:
      • Schema changes: avoid updating too much
      • Code
  • Create a DevFlag
  • Start the development

Usage

Add a new Flag

Open the app/devflag.php, prepare your application's environments. Add your flag into all envs:

return [
    'local' => [
        'useNewFeature' => true,
    ],
    'testing' => [
        'useNewFeature' => true,
    ],
    'staging' => [
        'useNewFeature' => false,
    ],
    'production' => [
        'useNewFeature' => false,
    ],
];

Check

Func-way:

function transfer(): ?Transaction
{
    $useNewFeature = useDevFlag('useNewFeature');

    if (!$useNewFeature) {
        return null;
    }

    // doing awesome things
    
    return $transaction;
}

OOP/DI-way:

use ShipSaaS\DevFlag\Contracts\DevFlagInterface;

public function __construct(private DevFlagInterface $devFlag) {}

public function transfer(): mixed
{
    if (!$this->devFlag->can('useNewFeature')) {
        return null;
    }
    
    // handle new things
}
