warden-authorize

Authorize access to socket.io against warden-based sessions.

Installation

npm install warden-authorize

Example usage

 
// initialize our modules
var io               = require("socket.io")(server),
    sessionStore     = require('sharedSessionStore'),
    WardenAuth       = require("warden-authorize");
 
io.use(WardenAuth.authorize({
  key:          'user',       // *optional* (default: user) the name of the model for warden session
  store:        sessionStore,        // we NEED to use a sessionstore. no memorystore please
  success:      onAuthorizeSuccess,  // *optional* callback on success
  fail:         onAuthorizeFail,     // *optional* callback on fail/error
}));
 
function onAuthorizeSuccess(data, accept){
  console.log('successful connection to socket.io');
 
  // The accept-callback still allows us to decide whether to
  // accept the connection or not.
  accept(null, true);
}
 
function onAuthorizeFail(data, message, error, accept){
  console.log('failed connection to socket.io:', message);
 
  if(error)
    accept(new Error(message));
}

Client-side

You have to provide the session-id as a query parameter like this.

socket = io.connect(socketIOURL, {
  // Note: you can get <server-session-id> from the session_id cookie
  query: 'session_id=' + '<server-session-id>'
});
