Avoid Firefox and Safari 404 error in preflight request from Nuxt.js app to Laravel / OctoberCMS API.

routes.php

// When using Nuxt.js in universal mode, bounded to extra domain API written in OctoberCMS, 
// this solves CORS issue in Firefox and Safari (network error during page change)

Route::options('/{any}', function() {
    $headers = [
        'Access-Control-Allow-Methods'=> 'POST, GET, OPTIONS, PUT, DELETE',
        'Access-Control-Allow-Headers'=> 'X-Requested-With, Content-Type, X-Auth-Token, Origin, Authorization'
    ];
    return \Response::make('You are connected to the API', 200, $headers);
})->where('any', '.*');

Thanks a lot, it's working also !
I spent many months on CORS and JWT, without help and was seriously considering to move to Strapi which handles JWT natively...

Glad to be helpful!

Very valuable information. Thanks!
