io server to use with matthewmueller/io
IO-server for use with io.
IO-server supports URL-based pooling. For example:
IOconnect'/app/a/1' // gets events from sockets connected to: /app/a/1IOconnect'/app/a/2' // gets events from sockets connected to: /app/a/2IOconnect'/app/a' // gets all events from sockets connected to: /app/a/*IOconnect'/app/b' // gets events from sockets connected to: /app/bIOconnect'/app' // gets all events from sockets connected to: /app/*IOconnect'/' // gets all events from all sockets
For security purposes, you'll probably want to prevent clients from connecting to root.
Note: For pooling to work, you'll need to add the
express.querymiddleware before engine.io handles the request.
You can catch any event sent to the server by using
eson'connection' IOIOon'signup'jsonid = uid;thisemit'signup successful' json;
Authentication is delegated to the middleware level of express. You can stack authentication or validation middleware before engine.io handles the request. See the example below for more information.
