How can I implement connection pooling in Node.js with MongoDB?

To implement connection pooling in Node.js with MongoDB, you can use the MongoDB Node.js driver. Here's a basic example.

What are the benefits of using connection pooling?

Connection pooling improves performance by reusing existing connections, reducing the overhead of establishing new connections.

Can you show me a code example for setting up a connection pool?

Sure! Here's a simple code snippet:

const { MongoClient } = require('mongodb');
const uri = 'your_mongodb_uri';
const client = new MongoClient(uri, { poolSize: 10 });

async function run() {
    try {
        await client.connect();
        console.log('Connected to MongoDB with connection pooling!');
    } finally {
        await client.close();
    }
}
run().catch(console.dir);
