Broadcasting with shoe sockjs

Question

I am trying to setup a simple scenerio using shoe + dnode +sockjs and I do not know how to broadcast a message to all users connected to the web application.

Do you know if there is a function or method which manage this? or should it be make by "hand"?

Answer 1

AFAIK, you have to roll it by "hand" as you say. Here is what I do:

server.js:

var shoe = require('shoe')

var connectedClients = {}
var conCount = 0

var sock = shoe(function(clientStream) {
  clienStream.id = conCount
  connectedClients[clientStream.id] = clientStream
  conCount += 1
})

somewhere else in your server-side program:

//write to all connected clients
Object.keys(connectedClients).forEach(function(cid) {
  var clientStream = connectedClients[cid]
  clientStream.write(yourData)
})

Note, you'll want to introduce additional logic to only write to connected clients, so you'll want to remove disconnected clients from connectedClients, something like delete connectedClients[id].

Hopefully that helps.
