Preventing a 'heartbeat timeout' with websockets and SocketIO
connection-timeout, socket.io, websocket
Solution
Check out the close timeout and heartbeat timeout options here
You can set these programmatically on the server via:
var io = require('socket.io').listen(80);
io.set('close timeout', 60);
io.set('heartbeat timeout', 60);
As for the design of your application, you should check out this question for whether or not you should change the timeout.
Problem
I am using NodeJS and SocketIO for my websocket solution. It works fine, but after a few minutes, my socket server always times out with the following messages in my console: ``` debug - fired heartbeat timeout for client info - transport end <heartbeat timeout> debug - set close timeout for client debug - cleared close timeout for client debug - discarding transport ``` Here is my complete `server.js` file: ``` var app = require('http').createServer(handler) , io = require('socket.io').listen(app) , fs = require('fs') app.listen(3000); function handler (req, res) { fs.readFile(__dirname + '/index.html', function (err, data) { if (err) { res.writeHead(500); return res.end('Error loading index.html'); } res.writeHead(200); res.end(data); }); } io.sockets.on('connection', function (socket) { socket.emit('news', { hello: 'from socket server' }); socket.on('swipe', function (from, msg) { console.log('I received a private message by ', from, ' saying ', msg); socket.emit('swipe event received on server!'); }); ``` How can I prevent the timeouts from happening?
