Actually i am getting the following error in .
Unhandled document message:[c:null,d:null]
My App.js file is given below.
var racer = require('racer'),
express = require('express'),
cookieParser = require('cookie-parser'),
redis = require("redis").createClient(6379,'127.0.0.1'),
bodyParser = require('body-parser'),
user = require("redis").createClient(6379,'127.0.0.1'),
session = require('express-session'),
RedisStore = require('connect-redis')(session),
app = express();
var mongo = require('mongojs');
db = 'entries',
collections = ['admin,entries'],
db = mongo.connect('127.0.0.1:27017/'+db, collections);
htpp = require('http'),
server = htpp.createServer(app);
//Create Store for redis and mongodb
var store = racer.createStore({
server: server,
db: require('livedb-mongo')('127.0.0.1:27017/test?auto_reconnect', {
safe: true
}),
redis: require('redis-url').connect('redis://127.0.0.1: 6379')
});

console.log('store',store);

//MiddleWare
app.use(express.static(__dirname + '/public'));
app.use(express.static(__dirname));
app.use(require('racer-browserchannel')(store));
app.use(bodyParser.json({
limit: '50mb'
}));
app.use(bodyParser.urlencoded({
limit: '50mb',
extended: true
}));
app.use(cookieParser());
app.use(session({
secret: "kqsdjfmlksdhfhzirzeoibrzecrbzuzefcuercazeafxzeokwdfzeijfxcerig",
store: new RedisStore({
host: '127.0.0.1',
port: 6379,
client: redis
})
}));

app.get('/',function(req,res){
res.sendfile('views/home.html');
});

app.get('/model', function (req, res) {
var model = store.createModel();
model.subscribe('entries', function (err, entries) {
if (err) {
res.status(500);
res.send(err);
} else {
model.bundle(function (err, bundle) {
res.send(JSON.stringify(bundle));
});
}
});
});

store.bundle(__dirname + '/client.js', function (err, js) {
app.get('/script.js', function (req, res) {
res.type('js');
res.send(js);
});
});
server.listen(8888);
console.log('server listening at the port'+8888);
Please help me for the solution.

This example hasn't been updated for a long time. I think racer has had a few API changes which most likely broke it, but I just made this as an example so I probably won't have any time to update this to a new version, sorry.

But i guess the problem is in mongodb . using this example i have already made one app.but in one app when server providing the home page,the home is loaded but looks blank.Can you please say why the below error arises.
Unhandled document message:[c:null,d:null]
Actually i am getting this error when the below code snippet started executing.

model.subscribe('entries', function (err, entries) {
if (err) {
res.status(500);
res.send(err);
} else {
model.bundle(function (err, bundle) {
res.send(JSON.stringify(bundle));
});
}
});

I'm also trying to get this to work. The official examples disappeared after racer 0.5.14. Can't get past "Unhandled document message:[c:null,d:null]".

Aha! https://github.com/derbyjs/racer-examples works!
