connect.router error and how to re-write it in node

I'm reading "Beginning Mobile Application Development in the Cloud" by Richard Rodger and some sample codes use Connect which, I have found, no longer allows direct request processing to the router layer. Here is a sample that gives a 'has no method router' error:

var common = require('./common.js');
var util    = common.util;
var connect = common.connect;
var mongo   = common.mongo;


var server = connect.createServer( 
  connect.router(function(app){ //gives the error: "has no method 'router'

    // POST {id:<string>}
    app.post('/todo/stats/init',function(req,res,next){
      common.readjson(req,function(json){
        common.sendjson(res,{ok:true,id:json.id});
      })
    })

    // POST {time:<UTC-millis>,total:<todos>,done:<done todos>}
    app.post('/todo/stats/collect/:id',function(req,res,next){
      var id = req.params.id;
      common.sendjson(res,{ok:true,id:id});
      common.readjson(req);
    })
  })
);


mongo.init('todo','localhost');
mongo.open()

server.listen(3000);

Most of the books about node include code that doesn't work and it is very frustrating for someone who begins now to learn and un-learn a minute later. Open Source framework undergoes amazingly fast changes! I just need to learn how to do this the right way. Any thoughts?
