Nó Socket.io

/*The following example attaches socket.io to a plain Node.JS HTTP server listening on port 3000.*/

const server = require('http').createServer();
const io = require('socket.io')(server);
io.on('connection', client => {
  client.on('event', data => { /* … */ });
  client.on('disconnect', () => { /* … */ });
});
server.listen(3000);



//Standalone

const io = require('socket.io')();
io.on('connection', client => { ... });
io.listen(3000);
//Module syntax
import { Server } from "socket.io";
const io = new Server(server);
io.listen(3000);
                               
                               
                               
//In conjunction with Express
//Starting with 3.0, express applications have become request handler functions that you pass to http or http Server instances. You need to pass the Server to socket.io, and not the express application function. Also make sure to call .listen on the server, not the app.

const app = require('express')();
const server = require('http').createServer(app);
const io = require('socket.io')(server);
io.on('connection', () => { /* … */ });
server.listen(3000);
                               
                               
//In conjunction with Koa
//Like Express.JS, Koa works by exposing an application as a request handler function, but only by calling the callback method.

const app = require('koa')();
const server = require('http').createServer(app.callback());
const io = require('socket.io')(server);
io.on('connection', () => { /* … */ });
server.listen(3000);
                               
                               
                               
//In conjunction with Fastify
//To integrate Socket.io in your Fastify application you just need to register fastify-socket.io plugin. It will create a decorator called io.

const app = require('fastify')();
app.register(require('fastify-socket.io'));
app.io.on('connection', () => { /* … */ });
app.listen(3000);

como executar o servidor Socket.io

const express = require("express");
const http = require("http");
const socketIo = require("socket.io");
const port = process.env.PORT || 8001;
const index = require("./routes/index");
const app = express();
app.use(index);
const server = http.createServer(app);
const io = socketIo(server); // < Interesting!
const getApiAndEmit = "TODO";
