Node Roundup: Surviving npm Downtime, Waf Wall of Shame, stream-chat, Vein

Posted on August 15, 2012 by Andrew Davis

Vein (License: MIT, npm: vein) is a WebSocket RPC module. It includes both client and server code, and a minimised build for browsers. RPC methods can be added using vein.add, and then called from clients:

// Server
vein.add('multiply', function(res, numOne, numTwo) {
  res.reply(numOne * numTwo);
});

// Browser
var vein = Vein.createClient();
vein.on('ready', function(services) {
  vein.multiply(2, 5, function(num) {
    // num === 10
  });
});
