Mongodb Get Started in NodeJs

Getting started with MongoDB in Node.js is super easy! Let me walk you through a simple "Hello MongoDB" project using both the native MongoDB driver and Mongoose, a popular ODM.


πŸš€ Step-by-Step: Connect MongoDB with Node.js


βœ… Option 1: Using the Native MongoDB Driver

πŸ“¦ Step 1: Install MongoDB driver

bash

npm install mongodb


πŸ“„ Step 2: Basic MongoDB Connection & Insert

js

const client = new MongoClient(uri);async function run() { try { await client.connect(); const db = client.db('myDatabase'); const collection = db.collection('users'); // Insert a document const result = await collection.insertOne({ name: 'Alice', age: 25 }); console.log('Inserted ID:', result.insertedId); // Find the document const user = await collection.findOne({ name: 'Alice' }); console.log('Found User:', user); } catch (err) { console.error(err); } finally { await client.close(); }}run();


πŸͺ„ Option 2: Using Mongoose (Beginner Friendly)

πŸ“¦ Step 1: Install Mongoose

bash

npm install mongoose


πŸ“„ Step 2: Connect, Define Schema & Use It

js

const mongoose = require('mongoose');mongoose.connect('mongodb://localhost:27017/myDatabase') .then(() => console.log('MongoDB connected!')) .catch(err => const userSchema = new mongoose.Schema({ name: String, age: Number});// Create a modelconst User = mongoose.model('User', userSchema);// Insert & Find a userconst newUser = new User({ name: 'Bob', age: 30 });newUser.save() .then(() => User.findOne({ name: 'Bob' })) .then(user => { console.log('Found User:', user); mongoose.disconnect(); });


🧠 Quick Tips

  • MongoDB automatically creates the database and collection the first time you insert data.

  • Use MongoDB Compass to view your local databases visually.

  • If you're using MongoDB Atlas, replace the URI with your cloud connection string.

Want to:

  • Build a full REST API?

  • Use MongoDB with Express.js?

  • Connect to MongoDB Atlas (cloud DB)?
