How do I delete a document in MongoDB using Node.js?

You can use the deleteOne or deleteMany methods from the MongoDB Node.js driver. Do you have a specific document in mind?

Yes, I want to delete a user with the name 'John Doe'.

You can do that with the following code:

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

async function deleteUser() {
    const client = new MongoClient('your_mongodb_uri');
    await client.connect();
    const database = client.db('your_database_name');
    const users = database.collection('users');

    const result = await users.deleteOne({ name: 'John Doe' });
    console.log(`${result.deletedCount} document(s) was/were deleted.`);
    await client.close();
}

deleteUser();

Make sure to replace 'your_mongodb_uri' and 'your_database_name' with your actual MongoDB URI and database name.

What if I want to delete multiple users?

You can use deleteMany instead. Here's how:

const result = await users.deleteMany({ age: { $lt: 18 } }); // Deletes all users under 18

This will delete all documents that match the criteria.
