Friends, how can I implement a similar chat https://nekto.me/chat on laravel?

Question

Chats

I'm more interested in the question of how to transfer messages between users with a minimum load, I heard about sockets, if they are the best option, then what library should I use?

Answer 1

https://laravel.com/docs/5.7/broadcasting A fairly large number of message transport options are described here.
You can also use https://pusher.com (how to make all this friends with Laravel, well, a lot of different good content in all languages, with pictures and videos)
How and where to store - how and anywhere (sql, nosql). To advise more specifically, a clearer statement of the problem is needed.
