Run nodejs command line module to output in nodejs web server?

Tag : node.js , By : dyarborough

wish of those help you could have 2 node instances. One the http server and the second instance the command line instance to run jasmine. The http server instance would spawn the command line instance. Then you could register a GET route on the http server such as someexample.com/runtests which would call the tests and wait for the tests to finish and respond with the console output. This is sort of unorthodox, but there wouldn't be a direct way to run command line applications through the browser without modifying their source.

Nodejs - websocket-node module: How to make multi-client socket-server works?

it fixes the issue You're not storing the connections on the server side. You're just setting them up on the server to communicate directly back and forth to the server. If you want messages going to the server to be sent back out to everyone, you need to set up the on.('message', ...) function for each connection on the server to have that behavior. To do this, you'll need to store the connections as they are created. Try this:
var WebSocketServer = require('websocket').server;
var http = require('http');

var server = http.createServer(function(request, response) {
    console.log((new Date()) + ' Received request for ' + request.url);
server.listen(5050, function() {
    console.log((new Date()) + ' Server is listening on port 5050');

wsServer = new WebSocketServer({
    httpServer: server,
    // You should not use autoAcceptConnections for production 
    // applications, as it defeats all standard cross-origin protection 
    // facilities built into the protocol and the browser.  You should 
    // *always* verify the connection's origin and decide whether or not 
    // to accept it. 
    autoAcceptConnections: false

function originIsAllowed(origin) {
  // put logic here to detect whether the specified origin is allowed. 
  return true;

//create an array to hold your connections
var connections = [];

wsServer.on('request', function(request) {
    if (!originIsAllowed(request.origin)) {
      // Make sure we only accept requests from an allowed origin 
      console.log((new Date()) + ' Connection from origin ' + request.origin + ' rejected.');
    var connection = request.accept('echo-protocol', request.origin);

    //store the new connection in your array of connections

    console.log((new Date()) + ' Connection accepted.');
    connection.on('message', function(message) {
        if (message.type === 'utf8') {
            console.log('Received Message: ' + message.utf8Data);

            //send the received message to all of the 
            //connections in the connection array
            for(var i = 0; i < connections.length; i++) {
        else if (message.type === 'binary') {
            console.log('Received Binary Message of ' + message.binaryData.length + ' bytes');
    connection.on('close', function(reasonCode, description) {
        console.log((new Date()) + ' Peer ' + connection.remoteAddress + ' disconnected.');
