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:

 1class StoreUserRequest extends FormRequest
 2{
 3    use DryRunnable;
 4 
 5    public function rules(): array
 6    {
 7        return [
 8            'email' => ['required', 'email', 'max:255', 'unique:users'],
 9            'username' => ['required', 'string', 'min:2', 'max:255', 'unique:users'],
10            'nickname' => ['nullable', 'string', 'min:2', 'max:255'],
11        ];
12    }
13}

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

1// 1. "Username is unavailable" validation error
2axios.post(
3        '/users',
4        { username: 'Agent007' },
5        { headers: { 'X-Dry-Run': true } }
6     )
7     .then(response => response.status);
