Node.js MongoDB Create a Database

Node.js MongoDB: Create a Database

Creating a MongoDB database from Node.js is simpler than you may think. Connect with the MongoClient ÔÇö and MongoDB creates the database automatically if it does not already exist.

Steps

• Create a folder (e.g. MongoDatabase).
• Create createdatabase.js inside it.
• Install the driver: npm install mongodb.

createdatabase.js

const { MongoClient } = require('mongodb');
const url = "mongodb://localhost:27017";

MongoClient.connect(url, function(err, client) {
  if (err) throw err;
  const db = client.db("MongoDatabase");
  console.log("Database ready!");
  client.close();
});

Run It

node createdatabase.js
# Output: Database ready!

Modern async/await

const { MongoClient } = require('mongodb');

async function run() {
  const client = new MongoClient("mongodb://localhost:27017");
  await client.connect();
  const db = client.db("MongoDatabase");
  await db.collection("init").insertOne({ created: new Date() });
  console.log("Database ready!");
  await client.close();
}
run().catch(console.error);

Important Note

MongoDB does not actually persist the database until you insert at least one document. Connecting alone is not enough ÔÇö that is why the async example above writes a document to make the database visible in show dbs.
