How do I add a catch-all OPTIONS route in Laravel

php
Route::options('/{any?}', function() {
    return response()->json([], 204);
})->where('any', '.*');

Let's break down the code:

1. `Route::options` defines a route that responds to the HTTP OPTIONS method.

2. `'/{any?}'` is the route URI. The `any` parameter is made optional by adding the `?` at the end. This allows the route to match any URI.

3. The second argument is a closure that returns the response for the OPTIONS request. In this example, we're returning a JSON response with an empty body and a 204 No Content status code.

4. `->where('any', '.*')` is a regular expression constraint that allows the `any` parameter to match any character.

This catch-all OPTIONS route will respond to any OPTIONS request made to your Laravel application, regardless of the specific URI. It's useful for handling CORS (Cross-Origin Resource Sharing) preflight requests, which are sent by the browser to check if a cross-origin request is allowed.

Make sure to place this route definition at the end of your route list, as catch-all routes should be defined last to avoid conflicts with other routes.
