Laravel Drift

Laravel Drift is a pre-deploy environment validation and configuration drift detection tool. It acts as a gatekeeper, comparing your .env against .env.example and running safety checks before your application boots.

Key Features

• No-Boot Validation: Runs without booting the Laravel application container for maximum safety and speed.
• Drift Detection: Identifies missing keys in .env or orphan keys in .env.example.
• Safety Gates: Prevents common deployment disasters like APP_DEBUG=true in production or using placeholder APP_KEY values.
• Extensible Rules: Easily add your own custom validation rules.
• CI/CD Integration: Simple exit code contracts to block failing builds.

Installation

You can install the package via composer:

composer require fr3on/laravel-drift

You can publish the config file with:

php artisan vendor:publish --tag="drift-config"

Usage

Run the drift check:

php artisan drift:check

In your CI/CD pipeline, use the --strict flag to treat warnings as errors:

php artisan drift:check --strict

Built-in Rules

Rule	Description	Status
AppDebugRule	Ensures APP_DEBUG is false when APP_ENV is production.	Fail
AppKeyRule	Validates presence, length, and ensures no placeholder values are used.	Fail
CompletenessRule	Compares .env keys against .env.example.	Fail/Warn
QueueDriverRule	Warns if QUEUE_CONNECTION=sync is used in production.	Warn

Custom Rules

You can create custom rules by implementing the Fr3on\Drift\Contracts\DriftRule interface:

use Fr3on\Drift\Contracts\DriftRule;
use Fr3on\Drift\EnvMap;
use Fr3on\Drift\RuleResult;

class MyCustomRule implements DriftRule
{
    public function check(EnvMap $env, EnvMap $example): RuleResult
    {
        if ($env->missing('MY_REQUIRED_KEY')) {
            return RuleResult::fail('MY_REQUIRED_KEY is missing!');
        }

        return RuleResult::pass();
    }
}

Register your rules in config/drift.php.
