The
client and server connect just fine. For some reason the emit on my
client is not firing correctly. I am trying to get the testEmit and testEmit2 working.
This is my server:
express = require 'express'
mongo = require 'mongodb'
app = express()
server = (require 'http').createServer(app)
io = (require '
socket.io').listen(server)
server.listen(8080)
app.use(express.static(__dirname + '/public'))
# db = new mongo.Db("documentsdb", new mongo.Server("localhost", 27017, auto_reconnect: true), {safe:true})
io.sockets.on 'connection', (socket) ->
console.log '
Socket.io is connected!'
#This returns an array of documents sorted via date by decreasing order. (Most recent documents first.)
socket.on 'loadRecentDocuments', ->
console.log 'Loading most recent documents.'
db.collection 'documents', (err, collection) ->
collection.find().sort(dateAdded: -1).toArray (err, documents) ->
#This emit is recieved at index.html where a javascript function sendDocuments manages the documents.
socket.emit 'sendDocuments', documents
return
#The index.html provides the code data from the search box via a javascript.
io.sockets.on 'findDocuments', (code) ->
#Returns an array of documents with the corresponding class code.
documentCodeToSearch = code
console.log 'Retreaving documents with code: ' + documentCodeToSearch
db.collection 'documents', (err, collection) ->
collection.find(code:documentCodeToSearch).toArray (err, documents) ->
socket.emit 'sendDocuments', documents
return
#Uploads a document to the server. documentData is sent via javascript from submit.html
io.sockets.on 'addDocument', (documentData) ->
console.log 'Adding document: ' + documentData
db.collection 'documents', (err, collection) ->
collection.insert documentData, safe: true
return
#Test
socket.io
io.sockets.on 'testEmit', ->
console.log('Emit recieved.')
socket.emit 'testEmit2', 'caca'
return
app.listen 1337
console.log "Listening on port 1337..."
This is my client:
