thanks lot
with io.sockets.clients[room].length; solved error get
missing error handler on `socket`. typeerror: cannot read property '8a675bfe1203e' of undefined @ socket.<anonymous> (c:\users\utente\projects\webrtc\server.js:30:38) @ emitone (events.js:77:13) @ socket.emit (events.js:169:7) @ socket.onevent (c:\users\utente\projects\webrtc\node_modules\socket.io\lib\socket.js:330:8) @ socket.onpacket (c:\users\utente\projects\webrtc\node_modules\socket.io\lib\socket.js:290:12) @ client.ondecoded (c:\users\utente\projects\webrtc\node_modules\socket.io\lib\client.js:193:14) @ decoder.emitter.emit (c:\users\utente\projects\webrtc\node_modules\socket.io\node_modules\socket.io-parser\node_modules\component-emitter\index.js:134:20) @ decoder.add (c:\users\utente\projects\webrtc\node_modules\socket.io\node_modules\socket.io-parser\index.js:247:12) @ client.ondata (c:\users\utente\projects\webrtc\node_modules\socket.io\lib\client.js:175:18) @ emitone (events.js:77:13)
from log says error thrown @ line 30: var numclients = io.sockets.clients(room).length;
the reason method io.sockets.clients(room); not longer work on socket.io v1.0+
you can obtain list of clients calling:
var clientslist = io.sockets.adapter.rooms[room]; var numclients = clientslist.length;
