sanctum VS echo

Going deeper than just blade files, Laravel is a full MVC framework and so includes things like Models and Controllers out of the box that can be used to organize your server-rendered code. Authentication is also baked in by default, and with first-party packages like Breeze, Sanctum, or Socialite, you can include user registration, login, API-based authentication, social sign-ups, and role-based permissions with near zero configuration.

Long story short, I found this issue that was closed and here is the comment of the laravel dev:

Laravel Sanctum is the go-to solution for token-based API authentication and SPA (Single page application) authentication. It uses an authentication guard when performing the SPA authentication.

Welcome to the dark side! If you're looking for even more reasons to love Laravel, check out Spatie's packages or some of Laravel's official ones like Cashier, Echo, or Sanctum.

See: https://github.com/laravel/sanctum/blob/eb191ddfc3ec04bbead33593bf982e871095f25c/src/SanctumServiceProvider.php#L75-L87

Laravel Echo (https://github.com/laravel/echo) is framework-agnostic; you could make it work with jQuery or anything else. Vue's not required.

Listen for events with Laravel Echo,

I use Laravel Echo https://github.com/laravel/echo

Laravel has several ways to accomplish this actually. The main being the Laravel Echo server https://github.com/laravel/echo

I'm using beyondcode/laravel-websockets with laravel/echo on localhost. Public channels work fine, I also tested private channels by giving productId manually and it works.
