什么是 websockets，我应该使用什么 js 框架

Question

I'm very new to the Java Script world , I use Laravel already for my backend but when it came to the websockets part I kinda got messy , because when I looked for websockets I have read that they all are depending on Node JS for real time apps like chat apps but also I have seen a tutorial making a chat app in Vue Js & laravel echo only without using node js ,

now the messy part for me is , If I want to learn socket.io (for example) should I learn Node Js first ? And is Vue js an alternative for the socketio ? and How about the ajax ? isn't it able to do the same performance ?

I'm sorry but It's kinda messy for me , I have looked for that but it is still messy for me , thanks for advance

Answer 1

If I want to learn socket.io (for example) should I learn Node Js first?

Yes. Since Socket.IO is a Node.js package, it's kind of a pre-requisite to learn Node. It's one of the easiest tools to learn though, so don't be intimidated.

And is Vue js an alternative for the socketio?

No. Vue.js is front-end framework, which means it's used to build the part of the website you actually see. Socket.io is a package (or framework) that enables bi-directional communication between the front-end and the back-end of your application. You can use it for example to build a chat application.

How about the ajax ? isn't it able to do the same performance?

No. Ajax is short for Asynchronous JavaScript And XML . Which basically means that you use Ajax requests from the front-end to the back-end. The difference here is that Websockets/Socket.IO gives you the bi-directional communication that Ajax lacks. You don't need Socket.IO for all communication though

Answer 2

I agree with everything exposed in the accepted answer except that Vuejs isn't an alternative. It is true that vuejs is a javascript framework to create frontends, but, if you have a nodejs server with a socketio server, you need a client (frontend) which must be able to communicate through socketio. You can see this by yourself here , this is one of the most common vue wrappers library to use socketio from vuejs. I hope this could help
