How to Connect MongoDB with Node.js Using MongoDB Native Driver: Complete Setup and Code Example with explanation

Description :

In this article, we’ll walk through how to set up a MongoDB connection using the MongoDB native driver in a Node.js project. MongoDB is a popular NoSQL database, and connecting it with Node.js using the official driver ensures fast and direct communication without extra abstraction layers like Mongoose.
We’ll cover installing the driver, writing a reusable connection function, handling connection errors, and using the connected client to perform database operations. This is especially useful for developers who want fine-grained control over database behavior or are building scalable enterprise applications.
The MongoDB native driver offers features like connection pooling, SSL support, read/write preferences, automatic reconnection, and flexible query building. It’s officially maintained by MongoDB, Inc., ensuring it stays updated with the latest MongoDB server versions.
Whether you're creating an API, a dashboard, or a real-time app, knowing how to directly connect and interact with your database is a critical backend skill.
