I am trying to run a Node.js script locally and it\'s giving me this error message:
===============================================================
The following works for me using the 1.1.11 mongo driver:
var db = new Db(Config.dbName, new Server("127.0.0.1", 27017, {}), {safe: true});
Without the {safe: true}
parameter I do get the same warning as you show in your question.
This warning was a very recent addition to the driver; you're probably using an older version of the driver on your server which is why you don't see the warning there.
