How to configure Laravel to return empty JSON as {}?

To configure Laravel to return empty JSON as {}, you can modify the toJson() method in your Eloquent model or collection like so:

1. Open your Eloquent model file (e.g., User.php) or create a new file if needed.
2. Add the following method to the model class:

1

public function toJson($options = 0)
{
    $data = parent::toJson($options);

    $decoded = json_decode($data, true);
    return json_encode($decoded ?: (object) []);
}

This method overrides the default toJson() method provided by Laravel to check if the JSON data is null or empty, and returns an empty object {} instead.

1. Save your changes and test the API endpoint that returns empty JSON data. It should now return {} instead of null.

By implementing this custom toJson() method in your model class, you can ensure that Laravel returns empty JSON as {} when needed.

public function index()
{

    if(empty($data)) {
        return response()->json(['message' => 'No data available'], 404);
    } else {
        return response()->json($data, 200);
    }
}

In this example, if the $data array is empty, a JSON response with a message and a 404 status code will be returned. Otherwise, the data will be returned with a 200 status code. You can customize the message and status code as needed for your application.
