npm install primus-broadcast
A plugin for primus that adds a broadcast function to the socket/spark that excludes the the instance you're broadcasting from, the same way it works in socket.io.
If you are using the primus-emitter plugin as well, this will favor the .send() function over the .write() function. (You will have to pass this plugin to primus after you pass the primus-emitter one.)
var primusBroadcast = require('primus-broadcast');
primus.use('broadcast', primusBroadcast);
spark.on('data', function message(data) {
// equivalent to socket.broadcast.emit() or socket.broadcast.send() in socket.io
spark.broadcast('Received some data');
});The implementation is very simple (look for yourself) but nice to have as a module.
