What Socket.IO is

Socket

Socket.IO is a library that enables real-time, bidirectional and event-based communication between the browser and the server. It consists of:

MagicOnion is a modern RPC framework for.NET platform that provides bi-directional real-time communications such as SignalR and Socket.io and RPC mechanisms such as WCF and web-based APIs. Socket.IO Client Library for Unity (mono /.NET 4.x, Unity 2019.4.2.f1 LTS) socket.io-unity by floatinghotpot is a very good project, but it had some problems with me. For example in the use of Action or Func. Exactly I could not use UniRx.

  • a Node.js server: Source | API
  • a Javascript client library for the browser (which can be also run from Node.js): Source | API

There are also several client implementation in other languages, which are maintained by the community:

  • Java: https://github.com/socketio/socket.io-client-java
  • C++: https://github.com/socketio/socket.io-client-cpp
  • Swift: https://github.com/socketio/socket.io-client-swift
  • Dart: https://github.com/rikulo/socket.io-client-dart
  • Python: https://github.com/miguelgrinberg/python-socketio
  • .Net: https://github.com/Quobject/SocketIoClientDotNet

How does that work?

The client will try to establish a WebSocket connection if possible, and will fall back on HTTP long polling if not.

WebSocket is a communication protocol which provides a full-duplex and low-latency channel between the server and the browser. More information can be found here.

So, in the best-case scenario, provided that:

  • the browser supports WebSocket (97% of all browsers in 2020)
  • there is no element (proxy, firewall, …) preventing WebSocket connections between the client and the server

you can consider the Socket.IO client as a “slight” wrapper around the WebSocket API. Instead of writing:

You will have, on the client-side:

The API on the server-side is similar, you also get a socket object which extends the Node.js EventEmitter class:

Socket.IO provides additional features over a plain WebSocket object, which are listed below.

But first, let’s detail what the Socket.IO library is not.

What Socket.IO is not

Socket.IO is NOT a WebSocket implementation. Although Socket.IO indeed uses WebSocket as a transport when possible, it adds additional metadata to each packet. That is why a WebSocket client will not be able to successfully connect to a Socket.IO server, and a Socket.IO client will not be able to connect to a plain WebSocket server either.

If you are looking for a plain WebSocket server, please take a look at ws or uWebSockets.js.

There are also talks to include a WebSocket server in the Node.js core.

On the client-side, you might be interested by the robust-websocket package.

Features

Here are the features provided by Socket.IO over plain WebSockets:

Socketioclientdotnet

  • reliability (fallback to HTTP long-polling in case the WebSocket connection cannot be established)
  • automatic reconnection
  • broadcasting to all clients or to a subset of clients (what we call “Room”)
  • multiplexing (what we call “Namespace”)
