`.blast()`

Broadcast a message to all sockets connected to the server (or any server in the cluster, if you have a multi-server deployment using Redis).

javascript

sails.sockets.blast(data);

or:

sails.sockets.blast(eventName, data);
sails.sockets.blast(data, socketToOmit);
sails.sockets.blast(eventName, data, socketToOmit);

Usage

	Argument	Type	Details
1	eventName	((string?))	Optional. Defaults to `'message'`.
2	data	((json))	The data to send in the message.
3	socketToOmit	((req?))	Optional. If provided, the socket associated with this socket request will not receive the message blasted out to everyone else. Useful when the broadcast-worthy event is triggered by a requesting user who doesn't need to hear about it again.

Example

In a controller action...

javascript

sails.sockets.blast('user_logged_in', {
  msg: 'User #' + user.id + ' just logged in.',
  user: {
    id: user.id,
    username: user.username
  }
}, req);

Notes

Be sure to check that req.isSocket === true before passing in req to this method. For the socket to be omitted, the current req must be from a socket request, not just any HTTP request.
