//$export MONGO_URL="mongodb://localhost:27017/items";
Items =  new Mongo.Collection('items');
  items: function(){
  //  Items.insert({title:"this is title 04",cteateAt:new Date()});

i tried also but same happend

did you publish/subscribe it ?. Meteor version 1.3+ removed autopublish package so you need to pub/sub in order to work.

Please note that when you do console.log you need to add .fetch() to your query, otherwise you will log the cursor object instead of actual data, which is not very helpful. So to debug you can try:

  items: function(){
  return Items.find();

Also, I don’t see any publication and subscription code in your example. If you don’t have autopublish package added to your project you won’t get any data on the client unless you publish it on the server and then subscribe to it on the client.

Finally, you MUST run meteor like this (you can also use export clause if you want):

MONGO_URL="mongodb://localhost:27017/items" meteor

In your example you’ve set a variable before and meteor didn’t catch this, because in your output you can see that it started its own MongoDB instance:

=> Started MongoDB

That doesn’t happen when you use external db.
