Deleting data from MongoDB in Node.js is straightforward — you can delete a single document, multiple documents, or even drop an entire collection.

Let’s cover both approaches:

✅ 1. Using Native MongoDB Driver

📦 Install the driver

bash
npm install mongodb

🧹 Delete One or Many Documents

js
await db.collection('users').drop();        // Drop collectionawait db.dropDatabase();                    // Drop entire database

🪄 2. Using Mongoose

📦 Install Mongoose

bash
npm install mongoose

🔥 Delete with Mongoose

js
const mongoose = require('mongoose');mongoose.connect('mongodb://localhost:27017/myDatabase')  .then(() => console.log('Connected!'))  .catch(err => console.error(err));// Schema & modelconst userSchema = new mongoose.Schema({  name: String,  age: Number});const User = mongoose.model('User', userSchema);// Delete oneUser.deleteOne({ name: 'Bob' }).then(() => {  console.log('Deleted one user');});// Delete manyUser.deleteMany({ age: { $gt: 50 } }).then(() => {  console.log('Deleted old users');});
