How do I perform insert operations in MongoDB using Node.js?

You can use the MongoDB Node.js driver to perform insert operations. First, ensure you have the driver installed using npm.

What does the code look like for inserting a document?

Here's a simple example:

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

async function run() {
    const client = new MongoClient('your_mongodb_uri');
    await client.connect();
    const database = client.db('your_database');
    const collection = database.collection('your_collection');

    const doc = { name: 'Alice', age: 25 };
    const result = await collection.insertOne(doc);
    console.log(`New document inserted with the id: ${result.insertedId}`);
    await client.close();
}
run();

Can I insert multiple documents at once?

Yes, you can use insertMany() to insert multiple documents. Here's how:

const docs = [
    { name: 'Bob', age: 30 },
    { name: 'Charlie', age: 35 }
];
const result = await collection.insertMany(docs);
console.log(`${result.insertedCount} documents were inserted.`);
