Is it possible to create a new database in MongoDB with Mongoose?

Question

I am trying to figure out if I can create a new database in MongoDB with Mongoose. I am running on Node, and I know the MongoDB driver for Node can do it, but I am wondering if

Answer 1

Just Try this code it's very simple and clean

const mongoose = require('mongoose');
mongoose.connect('mongodb://localhost:27017/yourdatabasename').then(() => console.log('Connected to MongoDB...')).catch((err) => console.error("Coudn't connect MongoDB....", err));

const customerSchema= new mongoose.Schema({ name: String,address: String,email:String,});

const Customer= mongoose.model('Customer',courseSchema);

async function createNewCustomer() {const customer= new Customer({name: 'new customer',address: 'new address',email: 'customer1@new.com',});const result = await customer.save();console.log(result);
}
createNewCustomer();

Yes, you can specify the database name in your connection string.

db = mongoose.connect('mongodb://localhost/dbname1')

As soon as you create a record with that connection, it will create the new database and collections under the database name of 'dbname1'. If you wanted to create a new database, you can specify a different connection string:

db = mongoose.connect('mongodb://localhost/dbname2')

and that will create all your records under the name 'dbname2'. Your documents will not import over to dbname2, you will have to do an import of those records if you wanted to do that. Hope that helps.
