A set of awesome Rector rules.

Installation

Install via Composer:

composer require kapersoft/awesome-rector-rules --dev

Then register the rules in your rector.php config:

use Kapersoft\AwesomeRectorRules\NullableTypeToUnionTypeRector;
use Kapersoft\AwesomeRectorRules\MoveNullToEndOfUnionTypeRector;

return static function (Rector\Config\RectorConfig $rectorConfig): void {
    $rectorConfig->rules([
        NullableTypeToUnionTypeRector::class,
        MoveNullToEndOfUnionTypeRector::class,
    ]);
};

Included Rector Rules

1. NullableTypeToUnionTypeRector

Description: Converts nullable types (e.g., ?int) to explicit union types with null (e.g., int|null).

Before:

function someFunction(?int $value): ?string
{
    return null;
}

After:

function someFunction(int|null $value): string|null
{
    return null;
}

2. MoveNullToEndOfUnionTypeRector

Description: Moves null to the end of union types for consistency (e.g., null|string → string|null).

Before:

function someFunction(null|string $param): null|int
{
}

After:

function someFunction(string|null $param): int|null
{
}
