what does var io = require('../..')(server) do?

I've build the project https://github.com/Automattic/socket.io/tree/master/examples/chat locally and it is working great. However, it would be nice to understand a little more about how a socket application works. In the main startup script one of the modules that is pulled in with require is var io = require('../..')(server) what does require('../..') do? thanks! When a path to a directory is given to require , it will implicitly look for an index.js in that directory. In this case, it's the equivalent of var socket = require("../../index.js"); var io = socket(server); In the example provided

Socket.IO: How do I remove a namespace

由 淺唱寂寞╮ 提交于 2019-12-05 05:49:08
I need to be able to construct and destruct socket.io namespaces on-the-fly. It is easily to find information how to create a namespace, but I find nothing about how I remove/disconnect the namespace to release its memory. Say I got the following code already running: var nsp = io.of('/my-namespace'); nsp.on('connection', function(socket){ console.log('someone connected'): }); nsp.emit('hi', 'everyone!'); How do I disconnect/remove the socket.io namespace created above? The io.of method just creates an array element: Server.prototype.of = function(name, fn){ if (String(name)[0] !== '/') name =

socket.io client connect disconnect

由 ≯℡__Kan透↙ 提交于 2019-12-02 19:12:21
I am unable to figure out why disconnecting / connecting a socket.io connection multiple times is not working ? Server side code: io.on('connection', function(socket){ console.log('a user connected'); socket.on('disconnect', function(){ console.log('user disconnected'); }); }); Client side code: var socket = io(); socket.on('connect', function() { console.log("connected from the client side"); }); $('#connect_button').click(function(){ socket.connect(); }); $('#disconnect_button').click(function(){ socket.disconnect(); }); It disconnects alright. But doesn't reconnect. I'm using Socket.io 1.0.

Socket.IO 1.0.x: Get socket by id

由 妖精的绣舞 提交于 2019-12-01 15:05:58
In the 0.9.x version, we can get socket by ID like this: io.sockets.socket(socketId) But in 1.0.x we can't. How to find a socket by id in 1.0.x? For socket.io 1.0 use: io.sockets.connected[socketId] For 0.9 its io.sockets.sockets[socketId] and not io.sockets.socket[socketId] himanshu yadav you can also use like: io.to(socketid).emit(); Socket.io Version 2.0.3+ let namespace = null; let ns = _io.of(namespace || "/"); let socket = ns.connected[socketId] // assuming you have id of the socket 来源： https://stackoverflow.com/questions/27055989/socket-io-1-0-x-get-socket-by-id
