How to connect with a Racer client running on Node to a Racer server also running on Node. You also need to comment out everything in node_modules/racer/lib/Model/connection.server.js.

example.js

var racer = require('racer');
var BCSocket = require('browserchannel').BCSocket;

racer.Model.prototype._createSocket = function(bundle) {
  var options = bundle.racerBrowserChannel;
  var base = options.base || '/channel';
  if (bundle.mount) base = bundle.mount + base;
  base = 'http://localhost:3000' + base;       /////////<====== Change this to the address and 
                                               /////////        port of your Racer server.
  return new BCSocket(base, options);
};

racer.init({
        "queries": [],
        "contexts": {
                "root": {
                        "fetchedDocs": {},
                        "subscribedDocs": {},
                        "fetchedQueries": {},
                        "subscribedQueries": {}
                }
        },
        "refs": [],
        "refLists": [],
        "fns": [],
        "filters": [],
        "collections": {},
        "racerBrowserChannel": {
                "reconnect": true,
                "hostPrefixes": null,
                "base": "/channel",
                "keepAliveInterval": 20000,
                "sessionTimeoutInterval": 30000,
                "cors": null,
                "headers": {
                        "Content-Type": "text/plain",
                        "Cache-Control": "no-cache, no-store, max-age=0, must-revalidate",
                        "Pragma": "no-cache",
                        "Expires": "Fri, 01 Jan 1990 00:00:00 GMT",
                        "X-Content-Type-Options": "nosniff"
                }
        }
});

racer.ready(function(model) {
  model.subscribe('people.520053830ec8ce34cfe72ab7', function(err) {
    if (err) throw err;
    // Now you can do something with the document you subscribed to.
    console.log(model.get('people.520053830ec8ce34cfe72ab7.name'));
  });
});
