Node.js mongodb set default safe variable

Question

I am trying to run a Node.js script locally and it\'s giving me this error message:

===============================================================         


        

Answer 1

I got it to work by setting the strict mode to false.

var db = new Db(config.dbName, new Server("127.0.0.1", 27017, {}), {safe: false, strict: false}); 

Answer 2

This worked for me!

var db = new Db((new DbServer('127.0.0.1', 27017), {w:-2,journal:false,fsync:false,safe: false})

Answer 3

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.
