Sails.js + Passport.js authentication through websockets

by

Alternatively, you can hijack the ‘router:request’ event to plug in passport for socket requests. I do this in ‘config/bootstrap.js’:

module.exports.bootstrap = function (cb) {

  var passport = require('passport'),
    initialize = passport.initialize(),
    session = passport.session(),
    http = require('http'),
    methods = ['login', 'logIn', 'logout', 'logOut', 'isAuthenticated', 'isUnauthenticated'];

  sails.removeAllListeners('router:request');
  sails.on('router:request', function(req, res) {
    initialize(req, res, function () {
      session(req, res, function (err) {
        if (err) {
          return sails.config[500](500, req, res);
        }
        for (var i = 0; i < methods.length; i++) {
          req[methods[i]] = http.IncomingMessage.prototype[methods[i]].bind(req);
        }
        sails.router.route(req, res);
      });
    });
  });
  cb();
};

With this approach you don’t need special handling for checking socket request authentication in policies. You do still need to hook up passport for non socket requests by way of express middleware.
