javascript - Meteor JS: Shopping Cart Without Login - session id, etc -


i'm working on e-commerce project. customers of e-commerce site able add items shopping cart , checkout without having login.

to this, have decided store items customers add shopping cart inside collection. e.g.

cartitems = new mongo.collection("cartitems");

in order differentiate customer's shopping cart items other customers, have decided add field

 var sessid = meteor.default_connection._lastsessionid;

e.g.

{     "_id" : "hco7jysaruybnquc9",     "qty" : 1,     "productid" : "haajzgxplk4zj3pxw",     "session" : "uqtiaeqiawsxlmu7a" }

to document added cartitems collection.

the problem solution whenever page refreshed, last session id changes , therefore cart becomes empty again though same user still using page.

also, documents added collection not cleaned (deleted) have no way of detecting if session going ended browser/user.

1.) what's ideal solution problem?

2.) how implement shopping cart know though page has been refreshed user using site same person , therefore should still keep same items in shopping cart? current solution of using session ids differentiate 1 cart item seems not suitable solution this...

3.) current solution of using last session ids, collection full of cart items session ids past , provide automatic clean-up functionality within app this. what's best way clean-up? there way detect 'end of session'?

thank much.
