The options [useMongoClient] is not supported

I am using mongodb-3.6.0.

My express code is 

var promise = mongoose.connect('mongodb://localhost/myapp', {
  useMongoClient: true
});

On running the app I am getting the options [useMongoClient] is not supported. My mongoose version in ^5.0.0-rc0.

Please help.

Here's what works for me node.js v14 + mongoose v6

mongoose.connect("mongodb://localhost:27017/your-db-name", {
  auth: {
    username: "user",
    password: "password",
  },
  authSource: "admin",
});

No Need of useMongoClient Flag Now with Newer version of mongoose.

{ 
    useMongoClient : true
}

The answer to this is pretty simple just remove { useMongoClient: true } flag from your code since the option is no longer necessary in mongoose 5.x and use { useNewUrlParser: true } since you might get a message that the current URL string parser is deprecated.

const mongoose = require('mongoose');
mongoose.connect('mongodb://127.0.0.1:27017/qunar', { useMongoClient: true });
mongoose.Promise = global.Promise;
module.exports = mongoose

answer:☟

Delete the first line of code { useMongoClient: true } and then restart the server

mongoose 5 doesn't require useMongoClient anymore. 

mongoose.connect('mongodb://localhost/DB_name');

is enough. You can check for the documentation of "Mongoose 5" here

There is not much documentation about this yet as Mongoose 5 is in release candidate stage but with mongoose 5 you don't need to provide useMongoClient option. Mongoose 5 is using Mongo client by default. So just remove this option.
