1My question is, In mongodb I can create database using "use dbname". Is is possible to create database using node.js in mongodb ( not using mongodb interface ).vkt– vkt2016-03-02 21:38:08 +00:00Commented Mar 2, 2016 at 21:38

1I don't use either of these tech but a simple google search is showing me a lot of response on how to create a mongodb database in node.js. If these are not helping you then I can't be of much more help. Edit your post with your code, a link to the tutorial/doc your using, and the error your getting and maybe others can helpMatthew Verstraete– Matthew Verstraete2016-03-02 21:53:23 +00:00Commented Mar 2, 2016 at 21:53

1Thanks Mathhew, I got a solution. We do not have any query for creating database using node.js but If you code for insertion then it would automatically create database for you.vkt– vkt2016-03-02 22:13:11 +00:00Commented Mar 2, 2016 at 22:13

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

MongoClient.connect is deprecatedIt depends on what you're using to interact with mongo, but you don't usually need to create the database. It's usually just created when you use it in your code.
For example if you use the mongodb native driver:
MongoClient.connect('mongodb://localhost:27017/myNewDatabase', function(err, db) {
// If a database called "myNewDatabase" exists, it is used, otherwise it gets created.
var collection = db.collection('myNewCollection');
// If a collection called "myNewCollection" exists, it is used, otherwise it gets created.
});
The driver api docs have lots of examples - http://mongodb.github.io/node-mongodb-native/2.0/api/

At first, install MongoDB module by running this command.
npm install mongodb --save
Just keep in mind that you can not create only database. You have to create also the collection to see your new database.
index.js
const mongodb = require('mongodb');
const uri = 'mongodb://localhost:27017';
const client = new mongodb.MongoClient(uri);
client.connect((err) => {
if (!err) {
console.log('connection created');
}
const newDB = client.db("YourNewDatabase");
newDB.createCollection("YourCreatedCollectionName"); // This line i s important. Unless you create collection you can not see your database in mongodb .
})
Now run this index file by the following command in your terminal
node index.js
