Connecting to a MongoDB collection in Node.js is super straightforward with the MongoDB Node.js driver or an ODM like Mongoose.

Let’s look at both approaches 👇

📦 Option 1: Using Native MongoDB Driver

1️⃣ Install the MongoDB Driver

bash
npm install mongodb

2️⃣ Connect and Access a Collection

js
const client = new MongoClient(uri);async function run() {  try {    await client.connect();    const db = client.db('myDatabase');         // Database name    const collection = db.collection('users');  // Collection name    // Example: Insert one    await collection.insertOne({ name: 'Alice', age: 25 });    // Example: Find all    const users = await collection.find().toArray();    console.log(users);  } catch (err) {    console.error(err);  } finally {    await client.close();  }}run();

🧙‍♂️ Option 2: Using Mongoose (Easier for Beginners)

1️⃣ Install Mongoose

bash
npm install mongoose

2️⃣ Create Schema + Connect to DB

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 model (maps to 'users' collection)const User = mongoose.model('User', userSchema);// Insert a userconst newUser = new User({ name: 'Bob', age: 30 });newUser.save().then(() => console.log('User added!'));// Find usersUser.find().then(users => console.log(users));

🧠 Quick Tips

• A collection is like a table (in relational DBs).

• You don’t need to "create" collections — MongoDB creates them when you insert data.

• Use MongoDB Atlas for cloud-hosted databases.
