Customize how your exceptions are rendered

You can customize how your exceptions are rendered by adding a 'render' method to your exception.

For example, this allows you to return JSON instead of a Blade view when the request expects JSON.

abstract class BaseException extends Exception
{
    public function render(Request $request)
    {
        if ($request->expectsJson()) {
            return response()->json([
                'meta' => [
                    'valid'   => false,
                    'status'  => static::ID,
                    'message' => $this->getMessage(),
                ],
            ], $this->getCode());
        }
 
        return response()->view('errors.' . $this->getCode(), ['exception' => $this], $this->getCode());
    }
}

class LicenseExpiredException extends BaseException
{
    public const ID = 'EXPIRED';
    protected $code = 401;
    protected $message = 'Given license has expired.'
}
