I am trying to install websocket on nodejs with npm I am getting following error.. I am installing it on windows.

npm install websocket 0 info it worked if it ends with ok 1 verbose cli [ 'C:\\Program Files (x86)\\nodejs\\\\node.exe', 1 verbose cli 'C:\\Program Files (x86)\\nodejs\\node_modules\\npm\\bin\\npm-cli.js', 1 verbose cli 'install', 1 verbose cli '[email protected]' ] 2 info using [email protected] 3 info using [email protected] 4 verbose node symlink C:\Program Files (x86)\nodejs\\node.exe 5 verbose config file C:\Users\tasleem\.npmrc 6 verbose config file C:\Program Files (x86)\nodejs\etc\npmrc 7 verbose config file C:\Program Files (x86)\nodejs\node_modules\npm\npmrc 8 verbose read json C:\Program Files (x86)\nodejs\package.json 9 verbose read json C:\Program Files (x86)\nodejs\node_modules\npm\package.json 10 verbose read json C:\Program Files (x86)\nodejs\node_modules\package\package.json 11 verbose read json C:\Program Files (x86)\nodejs\node_modules\websocket-1.0.6\package.json 12 verbose read json C:\Program Files (x86)\nodejs\package.json 13 verbose cache add [ '[email protected]', null ] 14 silly cache add name=undefined spec="[email protected]" args=["[email protected]",null] 15 verbose parsed url { pathname: '[email protected]', 15 verbose parsed url path: '[email protected]', 15 verbose parsed url href: '[email protected]' } 16 silly cache add name="websocket" spec="1.0.3" args=["websocket","1.0.3"] 17 verbose parsed url { pathname: '1.0.3', path: '1.0.3', href: '1.0.3' } 18 verbose addNamed [ 'websocket', '1.0.3' ] 19 verbose addNamed [ '1.0.3', '1.0.3' ] 20 verbose url raw websocket/1.0.3 21 verbose url resolving [ 'https://registry.npmjs.org/', './websocket/1.0.3' ] 22 verbose url resolved https://registry.npmjs.org/websocket/1.0.3 23 http GET https://registry.npmjs.org/websocket/1.0.3 24 error Error: connect ETIMEDOUT 24 error at errnoException (net.js:781:11) 24 error at Object.afterConnect [as oncomplete] (net.js:772:19) 24 error { [Error: connect ETIMEDOUT] code: 'ETIMEDOUT', errno: 'ETIMEDOUT', syscall: 'connect' } 25 error You may report this log at: 25 error <http://github.com/isaacs/npm/issues> 25 error or email it to: 25 error <[email protected]> 26 error System Windows_NT 6.1.7601 27 error command "C:\\Program Files (x86)\\nodejs\\\\node.exe" "C:\\Program Files (x86)\\nodejs\\node_modules\\npm\\bin\\npm-cli.js" "install" "[email protected]" 28 error cwd C:\Program Files (x86)\nodejs 29 error node -v v0.8.0 30 error npm -v 1.1.32 31 error syscall connect 32 error code ETIMEDOUT 33 error message connect ETIMEDOUT 34 error errno ETIMEDOUT 35 error ETIMEDOUT errno 36 verbose exit [ 1, true ]

Or I have got the WebSocket package , could someone tell where to extract this inside nodejs folder?

  • any reason why you would not just rely on socket.io to take care of web sockets for you? Commented Jun 26, 2012 at 6:24
  • No reason as such.. but I have not googled enough on Socket.io. Can it be integrated with nodejs? Commented Jun 26, 2012 at 6:35
  • There are many reasons, for example Socket.IO does not scale well. As for the question: it seems that this is a network problem. Commented Jun 26, 2012 at 6:36
  • so WebSocket is better than socket.io? @freakish Can you tell where to extract the WebSocket folder inside nodejs? Commented Jun 26, 2012 at 6:37
  • Not necessarly better - it depends on your needs. For example I use ws module. If you have WebSocket package, then you need to find a node_modules folder and extract it there. You may create one in your app's folder, if you wish to hold the library locally there. See this: nodejs.org/docs/v0.4.1/api/… Commented Jun 26, 2012 at 6:43

It seems that there is a connection problem between your site and the NPM registry. Try first to connect to NPM registry in a browser, you should have the same error.

Check your network connectivity, you can also try to ping registry.npmjs.org.

It is opening in browser but from command prompt it is telling timed out. What could be the problem?
Do you have a proxy to access to the Internet?
No i don't have. I don't know whats wrong.. Ok apart from that. If I have a WebSocket package where should I put it to use?
@Fahad - are you able to install anything using npm with the current versions of node/npm at the moment?

a "npm up -g" cannot hurt either..

I am not sure if this can help you. I was using nodejs on windows via. Cygwin and when I tried making javascripts with websockets I had problems with the standard node installation - it was too old, I then tried to install a new version of node from inside Cygwin, however this was NOT possible, so I proceeded to install it using "node-v0.10.24-x64.msi" which can be downloaded from http://nodejs.org/download/

After download I then copied manually all contents from folder nodejs to cygwin /usr/local/bin

In order to install ws (websockets) then npm is needed and for that you need the newest version - after copying manually whole folder nodejs, then you can start cygwin and write following:

node -v

it should write something like this :

$ node -v

v0.10.24

now you can procede with following:

$ cd /usr/local/bin/node_modules/npm/bin

$ node npm-cli.js install ws

$ node npm-cli.js install websockets

the npm-cli.js is a command line interface version of npm, made in javascript and nodejs can parse it, so now ws module should be installed

-- NOTE it is very important that you copy or move the folder "node_modules" after the installation to following place :

cygwin/home/ --your user-- /node_modules

Otherwise your javascript projects will not beable to see the installed modules - it is actually strange why, but I have no answer for that - I just made a copy and then it worked

I hope you can use this answer

one extra thing - if you are considering using standard websocket with javascript, then make sure you follow HyBi-10 or later, since HyBi-00 is faulty - it is however in use in old mobile phones browsers - I unfortunately could not get basic connection working with HyBi-00, due to security reasons and I guess that is why HyBi-00 is discontinued and HyBi-10 is newest standard

Step1 : Set up server Express takes the role of HTTP server, serving HTML file and wiring Websocket service

var express = require('express') var ws = require('./ws') var app = express() app.get('/', function (req, res) { res.sendfile(__dirname + '/ws.html'); }) app.listen(3000, function () { console.log('app listening on port 3000!') })

Step2 : Set up Client websocket client is a browser supported object.

Below is goind to introduce 3 importand fucntion:

ws.onopen : emmited when connected ws.send : sending a send event to websocket server ws.onmessage : event emmited when receiving message

 <script> var ws = new WebSocket('ws://localhost:40510'); // event emmited when connected ws.onopen = function () { console.log('websocket is connected ...') // sending a send event to websocket server ws.send('connected') } // event emmited when receiving message ws.onmessage = function (ev) { console.log(ev); } </script>
