Error message when connecting to MongoDB with NodeJs

I am connecting to my MongoDB with node.js. The server connects to the database, but I get an annoying error message.

This is the error:

(node:9252) DeprecationWarning: current URL string parser is deprecated, and will be removed in a future version. To use the new parser, pass option { useNewUrlParser: true } to MongoClient.connect.

here is my code which is located in a separate file that : server.js:

module.exports = {
    mongoURI: 'mongodb://127.0.0.1:27017/shoppinglist'
}

I wish to connect to mongodb without having any errors. I am running version 3.4.18

First of all, it is not an error, it is just a warning and it would not bother the functioning. If you don't want to see this warning, I recommend two methods.

First, by using { useNewUrlParser: true } you can avoid this warning message.

 MongoClient.connect('mongodb://127.0.0.1:27017/shoppinglist', { useNewUrlParser: true });

Second, most probably you are using mongo version >= 3.1.0 and to avoid this warning you can use 3.0.x releases.

"dependencies": {
  "mongodb": "~3.0.8"
}

It's not an error it's a warning (related to mongo version):

Mongo >= 3.1.0 

MongoClient.connect("mongodb://localhost:27017/shoppinglist", { useNewUrlParser: true })

The warning message suggestion should fix the problem, you just need to add:

{ useNewUrlParser: true }

to your MongoClient.connect to be like this:

MongoClient.connect('mongodb://127.0.0.1:27017/shoppinglist', { useNewUrlParser: true });
