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:
- Open your Eloquent model file (e.g., User.php) or create a new file if needed.
- Add the following method to the model class:
1 2 3 4 5 6 7 |
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.
- 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.

How do I handle empty JSON responses in Laravel?
In Laravel, you can handle an empty JSON response by using the response() method and returning an appropriate HTTP status code. You can use a ternary operator to check if the response is empty and return a specific message or status code. Here is an example of how you can handle empty JSON responses in Laravel:
1 2 3 4 5 6 7 8 9 10 |
public function index() { $data = []; // Your data array or collection if(empty($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.
