📖 Usage

Basic Usage

use function respond;

// Success response
return respond()->success($data, 'Operation successful');

// Error response
return respond()->error('Something went wrong', null, 400);

// Custom response
return respond()->response($data, 'Custom message', 200, true, 'custom-action');

Helper Function

The package provides a global respond() helper function:

// In your controller
public function index()
{
    $users = User::all();
    return respond()->success($users, 'Users retrieved successfully');
}

public function store(Request $request)
{
    $user = User::create($request->validated());
    return respond()->created($user, 'User created successfully');
}

public function show($id)
{
    $user = User::findOrFail($id);
    return respond()->ok('User retrieved successfully', $user);
}

HTTP Status Codes

The package provides pre-built methods for common HTTP status codes:

// 200 OK
return respond()->ok('Operation successful', $data);

// 201 Created
return respond()->created($data, 'Resource created successfully');

// 202 Accepted
return respond()->accepted('Request accepted', $data);

// 204 No Content
return respond()->noContent('Resource deleted successfully');

// 400 Bad Request
return respond()->badRequest('Invalid request data');

// 401 Unauthorized
return respond()->unauthorized('Authentication required');

// 403 Forbidden
return respond()->forbidden('Access denied');

// 404 Not Found
return respond()->notFound('Resource not found');

// 409 Conflict
return respond()->conflict('Resource already exists');

// 422 Unprocessable Entity
return respond()->unprocessableEntity('Validation failed', $errors);

// 429 Too Many Requests
return respond()->tooManyRequests('Rate limit exceeded');

// 500 Internal Server Error
return respond()->internalServerError('An error occurred');

// 502 Bad Gateway
return respond()->badGateway('Bad gateway');

// 503 Service Unavailable
return respond()->serviceUnavailable('Service temporarily unavailable');

// 504 Gateway Timeout
return respond()->gatewayTimeout('Gateway timeout');

Pagination Support

The package automatically handles paginated resources:

public function index()
{
    $users = User::paginate(15);
    return respond()->success($users, 'Users retrieved successfully');
}

This will automatically include pagination metadata in the response:

{
    "status": true,
    "code": 200,
    "action": "success",
    "message": "Users retrieved successfully",
    "data": [...],
    "pagination": {
        "total": 100,
        "per_page": 15,
        "current_page": 1,
        "last_page": 7,
        "from": 1,
        "to": 15,
        "links": {
            "current": "http://example.com/api/users?page=1",
            "first": "http://example.com/api/users?page=1",
            "last": "http://example.com/api/users?page=7",
            "prev": null,
            "next": "http://example.com/api/users?page=2"
        }
    }
}

Customizing Response Keys

You can customize the response keys by creating a new instance with custom keys:

$respond = new \Rawnoq\ApiResponse\Support\Respond(
    status_key: 'success',
    enable_status_key: true,
    data_key: 'payload',
    message_key: 'msg',
    messages_key: 'errors'
);

return $respond->success($data, 'Operation successful');

Or use the helper function with configuration:

$respond = respond();
$respond->status_key = 'success';
$respond->data_key = 'payload';
$respond->message_key = 'msg';

return $respond->success($data, 'Operation successful');

Array Messages

You can pass arrays of messages:

return respond()->error([
    'Email is required',
    'Password must be at least 8 characters'
], null, 422);

This will include both message (first message) and messages (all messages) in the response:

{
    "status": false,
    "code": 422,
    "action": "error",
    "message": "Email is required",
    "messages": [
        "Email is required",
        "Password must be at least 8 characters"
    ]
}

⚙️ Configuration

Publish the configuration file:

php artisan vendor:publish --tag=api-response-config

This will create config/api-response.php:

return [
    'status_key' => 'status',
    'enable_status_key' => true,
    'data_key' => 'data',
    'message_key' => 'message',
    'messages_key' => 'messages',
];
