CORS doesn't works when I'm trying to dd(), dump().

[fesh-biz]

All requests works fine until I'm not trying to dd(), dump()

I had read several treads and didn't found solution for me, so maybe this will helps.

This is doc quote from here https://packagist.org/packages/barryvdh/laravel-cors

If you echo(), dd(), die(), exit(), dump() etc in your code, you will break the Middleware flow. When output is sent before headers, CORS cannot be added. When the scripts exits before the CORS middleware finished, CORS headers will not be added. Always return a proper response or throw an Exception.

To solve it In my case I had simply added 2 helpers and added it in composer.json

composer.json

...
"autoload": {
        "files": [
            "app/Helpers/helpers.php"
        ],
...

app/Helpers/helpers.php

/*
 * dd() with headers
 */
if (!function_exists('ddh')) {
    function ddh($var){
        header('Access-Control-Allow-Origin: *');
        header('Access-Control-Allow-Methods: *');
        header('Access-Control-Allow-Headers: *');
        dd($var);
    }
}

/*
 * dump() with headers
 */
if (!function_exists('dumph')) {
    function dumph($var){
        header('Access-Control-Allow-Origin: *');
        header('Access-Control-Allow-Methods: *');
        header('Access-Control-Allow-Headers: *');
        dump($var);
    }
}

P.S. I don't know how to use issue form correctly so I hope that I didn't broke any rules. Just wanted to help

There is solution in my message above. You need to add 2 functions ddh, dumph. ddh means that this is still dd but now it has necessary headers inside.
