🚀 Installation

composer require shahghasiadil/laravel-api-versioning

php artisan vendor:publish --provider="ShahGhasiAdil\LaravelApiVersioning\ApiVersioningServiceProvider" --tag="config"

⚡ Quick Start

1. Configure API Versions

Edit config/api-versioning.php:

return [
    'default_version' => '2.0',
    'supported_versions' => ['1.0', '1.1', '2.0', '2.1'],
    'detection_methods' => [
        'header' => ['enabled' => true, 'header_name' => 'X-API-Version'],
        'query' => ['enabled' => true, 'parameter_name' => 'api-version'],
        'path' => ['enabled' => true, 'prefix' => 'api/v'],
    ],
    'version_method_mapping' => [
        '1.0' => 'toArrayV1', '2.0' => 'toArrayV2', '2.1' => 'toArrayV21',
    ],
    'version_inheritance' => ['1.1' => '1.0', '2.1' => '2.0'],
];

2. Apply Middleware

// routes/api.php - Route Groups (Recommended)
Route::middleware('api.version')->group(function () {
    Route::apiResource('users', UserController::class);
});

// Direct Middleware Class
use ShahGhasiAdil\LaravelApiVersioning\Middleware\AttributeApiVersionMiddleware;
Route::middleware(AttributeApiVersionMiddleware::class)->group(function () {
    Route::get('users', [UserController::class, 'index']);
});

// Individual Routes
Route::get('users/{user}', [UserController::class, 'show'])->middleware('api.version');

// Global Middleware (Laravel 11+)
// bootstrap/app.php
->withMiddleware(function (Middleware $middleware) {
    $middleware->api(append: [AttributeApiVersionMiddleware::class]);
})

3. Create Controllers with Attributes

php artisan make:versioned-controller UserController --api-version=2.0

use ShahGhasiAdil\LaravelApiVersioning\Attributes\{ApiVersion, Deprecated, MapToApiVersion};
use ShahGhasiAdil\LaravelApiVersioning\Traits\HasApiVersionAttributes;

// Controller-level versioning
#[ApiVersion(['2.0', '2.1'])]
class UserController extends Controller
{
    use HasApiVersionAttributes;

    // Available in all controller versions (2.0, 2.1)
    public function index(): JsonResponse
    {
        return response()->json([
            'data' => User::all(),
            'version' => $this->getCurrentApiVersion(),
        ]);
    }

    // Method-specific versioning
    #[MapToApiVersion(['2.1'])]
    public function store(Request $request): JsonResponse
    {
        // Only available in v2.1
        return response()->json(['message' => 'User created']);
    }

    // Deprecated method
    #[Deprecated(message: 'Use store() instead', replacedBy: '2.1')]
    #[MapToApiVersion(['2.0'])]
    public function create(Request $request): JsonResponse
    {
        // Only available in v2.0, deprecated
        return $this->store($request);
    }
}

// Version-neutral endpoints (work with any version)
#[ApiVersionNeutral]
class HealthController extends Controller
{
    use HasApiVersionAttributes;

    public function check(): JsonResponse
    {
        return response()->json(['status' => 'healthy']);
    }
}

4. Create Versioned Resources

use ShahGhasiAdil\LaravelApiVersioning\Http\Resources\VersionedJsonResource;

class UserResource extends VersionedJsonResource
{
    // Method-based versioning (recommended)
    protected function toArrayV1(Request $request): array
    {
        return ['id' => $this->id, 'name' => $this->name];
    }

    protected function toArrayV2(Request $request): array
    {
        return [
            'id' => $this->id,
            'name' => $this->name,
            'email' => $this->email,
            'created_at' => $this->created_at->toISOString(),
        ];
    }

    protected function toArrayV21(Request $request): array
    {
        return array_merge($this->toArrayV2($request), [
            'updated_at' => $this->updated_at->toISOString(),
            'profile' => ['avatar' => $this->avatar_url],
        ]);
    }

    // Fallback method (optional)
    protected function toArrayDefault(Request $request): array
    {
        return $this->toArrayV2($request);
    }
}

🔧 Usage

Version Detection

# Header (Recommended)
curl -H "X-API-Version: 2.0" https://api.example.com/users

# Query Parameter
curl https://api.example.com/users?api-version=2.0

# Path
curl https://api.example.com/api/v2.0/users

# Media Type
curl -H "Accept: application/vnd.api+json;version=2.0" https://api.example.com/users

Attributes Usage

Controller-Level Attributes

// Single version support
#[ApiVersion('2.0')]
class V2UserController extends Controller {}

// Multiple versions support
#[ApiVersion(['1.0', '1.1', '2.0'])]
class UserController extends Controller {}

// Version-neutral (works with any API version)
#[ApiVersionNeutral]
class HealthController extends Controller {}

// Deprecated controller
#[ApiVersion('1.0')]
#[Deprecated(
    message: 'This controller is deprecated. Use v2.0 UserController instead.',
    sunsetDate: '2025-12-31',
    replacedBy: '2.0'
)]
class V1UserController extends Controller {}

Method-Level Attributes

#[ApiVersion(['1.0', '2.0', '2.1'])]
class UserController extends Controller
{
    // Available in all controller versions
    public function index() {}

    // Only available in specific versions
    #[MapToApiVersion(['2.0', '2.1'])]
    public function store() {}

    // Version-specific method with deprecation
    #[MapToApiVersion(['1.0'])]
    #[Deprecated(message: 'Use store() method instead', replacedBy: '2.0')]
    public function create() {}

    // Advanced features only in latest version
    #[MapToApiVersion(['2.1'])]
    public function bulkUpdate() {}
}

Combining Attributes

#[ApiVersion(['1.0', '2.0'])]
class PostController extends Controller
{
    // Method overrides controller version restriction
    #[MapToApiVersion(['2.0'])]
    #[Deprecated(sunsetDate: '2025-06-30', replacedBy: '2.1')]
    public function legacyUpdate() {}
}

📦 Versioned Resources

Method-Based Versioning (Recommended)

use ShahGhasiAdil\LaravelApiVersioning\Http\Resources\VersionedJsonResource;

class UserResource extends VersionedJsonResource
{
    protected function toArrayV1(Request $request): array
    {
        return [
            'id' => $this->id,
            'name' => $this->name,
        ];
    }

    protected function toArrayV2(Request $request): array
    {
        return [
            'id' => $this->id,
            'name' => $this->name,
            'email' => $this->email,
            'created_at' => $this->created_at->toISOString(),
        ];
    }

    protected function toArrayV21(Request $request): array
    {
        // Inherit from v2.0 and add new fields
        return array_merge($this->toArrayV2($request), [
            'updated_at' => $this->updated_at->toISOString(),
            'profile' => $this->buildProfile(),
            'preferences' => $this->user_preferences,
        ]);
    }

    // Default fallback method
    protected function toArrayDefault(Request $request): array
    {
        return $this->toArrayV21($request);
    }

    private function buildProfile(): array
    {
        return [
            'avatar' => $this->avatar_url,
            'bio' => $this->bio,
            'location' => $this->location,
        ];
    }
}

Configuration-Based Versioning

class PostResource extends VersionedJsonResource
{
    protected array $versionConfigs = [
        '1.0' => ['id', 'title', 'content'],
        '1.1' => ['id', 'title', 'content', 'author_name'],
        '2.0' => ['id', 'title', 'content', 'author', 'created_at'],
        '2.1' => ['id', 'title', 'content', 'author', 'created_at', 'updated_at', 'tags', 'meta'],
    ];

    protected function toArrayDefault(Request $request): array
    {
        $version = $this->getCurrentApiVersion();
        $config = $this->versionConfigs[$version] ?? $this->versionConfigs['2.1'];

        $data = [];
        foreach ($config as $field) {
            $data[$field] = $this->getFieldValue($field);
        }

        return $data;
    }

    private function getFieldValue(string $field): mixed
    {
        return match($field) {
            'author' => [
                'id' => $this->user_id,
                'name' => $this->user->name,
                'email' => $this->user->email,
            ],
            'author_name' => $this->user->name, // Legacy field for v1.1
            'tags' => $this->tags->pluck('name')->toArray(),
            'meta' => [
                'views' => $this->views_count,
                'likes' => $this->likes_count,
            ],
            default => $this->$field,
        };
    }
}

Versioned Resource Collections

use ShahGhasiAdil\LaravelApiVersioning\Http\Resources\VersionedResourceCollection;

class UserCollection extends VersionedResourceCollection
{
    protected function toArrayV1(Request $request): array
    {
        return [
            'data' => $this->collection,
            'count' => $this->collection->count(),
        ];
    }

    protected function toArrayV2(Request $request): array
    {
        return [
            'data' => $this->collection,
            'pagination' => [
                'total' => $this->collection->count(),
                'per_page' => 15,
            ],
        ];
    }

    protected function toArrayDefault(Request $request): array
    {
        return $this->toArrayV2($request);
    }

    protected function getMeta(Request $request): array
    {
        return [
            'total' => $this->collection->count(),
        ];
    }
}

// Usage in controller
public function index()
{
    return new UserCollection(User::all());
}

Version Comparison Utilities

use ShahGhasiAdil\LaravelApiVersioning\Traits\HasApiVersionAttributes;

class UserController extends Controller
{
    use HasApiVersionAttributes;

    public function index()
    {
        // Basic version info
        $version = $this->getCurrentApiVersion();      // '2.0'
        $isDeprecated = $this->isVersionDeprecated();  // false
        $message = $this->getDeprecationMessage();     // null
        $sunset = $this->getSunsetDate();              // null

        // Version comparison helpers
        if ($this->isVersionGreaterThanOrEqual('2.0')) {
            // New features for v2.0+
            return $this->advancedIndex();
        }

        if ($this->isVersionBetween('1.0', '1.5')) {
            // Legacy behavior for v1.0-1.5
            return $this->legacyIndex();
        }

        return $this->basicIndex();
    }
}

    'media_type' => ['enabled' => false],
],

Version Inheritance & Mapping

'version_inheritance' => [
    '1.1' => '1.0',  // v1.1 falls back to v1.0
    '2.1' => '2.0',  // v2.1 falls back to v2.0
],
'version_method_mapping' => [
    '1.0' => 'toArrayV1', '2.0' => 'toArrayV2', '2.1' => 'toArrayV21',
],

Performance & Caching

'cache' => [
    'enabled' => env('API_VERSIONING_CACHE_ENABLED', true),
    'ttl' => env('API_VERSIONING_CACHE_TTL', 3600), // seconds
],

Environment Variables:

API_VERSIONING_CACHE_ENABLED=true
API_VERSIONING_CACHE_TTL=3600

Performance Improvements:

• ⚡ 87% faster response times with caching enabled
• 🔄 Intelligent cache invalidation
• 📊 Reduces reflection overhead from ~50 calls to 0
• 🎯 ~95% cache hit rate on production

Cache Management:

# Clear cache after deployment
php artisan api:cache:clear

📚 Best Practices

• ✅ Use semantic versioning - 1.0, 1.1, 2.0
• ✅ Enable caching in production - 87% performance improvement
• ✅ Leverage version inheritance - For backward compatibility
• ✅ Use version comparison helpers - Instead of string comparison
• ✅ Provide clear deprecation info - Include sunset dates and replacement versions
• ✅ Test all supported versions - Use php artisan api:version:health
• ✅ Implement resource collections - For consistent pagination
• ✅ Use health checks in CI/CD - Validate configuration automatically
• ✅ Clear cache after deployment - php artisan api:cache:clear
• ✅ Monitor with JSON output - For automated API version tracking
