Dropping (deleting) a collection in MongoDB using Node.js is quick and easy. Here's how to do it with both the native MongoDB driver and Mongoose.

✅ 1. Using Native MongoDB Driver

📦 Step 1: Install the MongoDB Driver

bash
npm install mongodb

🧹 Step 2: Drop a Collection

js
const mongoose = require('mongoose');mongoose.connect('mongodb://localhost:27017/myDatabase')  .then(async () => {    console.log('Connected to MongoDB');    // Define model    const User = mongoose.model('User', new mongoose.Schema({ name: String }));    // Drop collection    await User.collection.drop();    console.log('Collection dropped!');    await mongoose.disconnect();  })  .catch(err => {    if (err.message.includes('ns not found')) {      console.log('Collection does not exist!');    } else {      console.error('Error:', err);    }  });

🧠 Notes

• If the collection doesn’t exist, MongoDB will throw an error — handle it gracefully.

• Dropping a collection deletes all documents and the structure of that collection.

• Be careful: This operation is irreversible.

Let me know if you want to:

• Drop all collections

• Drop an entire database

• Rebuild the collection afterward
