Validate Your App on the Frontend With Laravel Dry Run Requests

The Laravel Dry Requests package checks if your requests would pass validation if you executed them normally. Think of it as the equivalent of a --dry-run CLI flag for request validation. Using this package, you can hit the endpoint users are using to enter a form and get real-time feedback with 100% validation accuracy:

The way it works under the hood is that it runs validation logic for a controller but skips the controller action. This package returns a 200 OK status response when given an X-Dry-Run: true header. Fields not present get omitted dynamically using the sometimes rule to ensure good UX.

You can start using this validation package by either adding a DryRunnable trait to a form request or using $request->validate() directly:

class StoreUserRequest extends FormRequest
{
    use DryRunnable;
 
    public function rules(): array
    {
        return [
            'email' => ['required', 'email', 'max:255', 'unique:users'],
            'username' => ['required', 'string', 'min:2', 'max:255', 'unique:users'],
            'nickname' => ['nullable', 'string', 'min:2', 'max:255'],
        ];
    }
}

On the frontend, you need to send the X-Dry-Run header to validate form input before submitting the whole form:

// 1. "Username is unavailable" validation error
axios.post(
        '/users',
        { username: 'Agent007' },
        { headers: { 'X-Dry-Run': true } }
     )
     .then(response => response.status);
