Create new mongoDB with nodejs

I installed MongoDB 4.0 in local host. There are 3 default database as below

> show dbs
admin   0.078GB
config  0.078GB
local   0.078GB

Then I tried to create a new db using nodejs

var MongoClient = require('mongodb').MongoClient;
var url = "mongodb://local:27017/mydatabase"; // mydatabase is the name of db 
MongoClient.connect(url, function(err, db) {
    if (err) throw err;
    console.log("Database created!");
    db.close();
});

Above code work fine. I can see message "Database created!".

However , when I show dbs again , newly created mydatabase does not show up. There are still 3 databases .

> show dbs
admin   0.078GB
config  0.078GB
local   0.078GB

May I know what I did wrong ?

Thanks ALex

Important thing to know while creating MongoDB database is that A database is not created until it gets content! . You need to create at least one collection.

Hopes this clears your doubt.

Your MongoDb database will not be created until you create at least one collection with at least one record, so create a collection and add at least one record in it to see the database using 'show dbs'.
