How to Use MongoDB with Node.js in 2025

Using MongoDB with Node.js has become a common stack for building modern web applications due to their scalability and JSON-like format. With the advancements in both technologies, integrating MongoDB with Node.js in 2025 is easier and more efficient. This guide will take you through setting up a Node.js application using MongoDB and implementing key operations.

Why Choose MongoDB and Node.js?

MongoDB is a NoSQL database that stores data in flexible, JSON-like documents, which makes it ideal for applications with rapidly evolving requirement structures. Node.js, on the other hand, allows for event-driven, non-blocking I/O models, which complement MongoDB’s asynchronous nature, providing a fast and scalable tech stack.

Step-by-Step Guide to Integrate MongoDB with Node.js

1. Setting Up Your Environment

Before jumping into coding, ensure you have the following tools:

• Node.js: Ensure you have Node.js installed. Download the latest version from Node.js official website.
• MongoDB: Install MongoDB from the official MongoDB website.
• npm: This will be installed alongside Node.js.

2. Initialize a Node.js Project

Start by creating a new directory for your project and initialize it with npm:

mkdir my-mongo-app
cd my-mongo-app
npm init -y

3. Install Required Packages

For MongoDB integration, you’ll need the mongodb package:

npm install mongodb

4. Connecting to MongoDB

Create a file app.js and start by including the MongoDB client:

const { MongoClient } = require('mongodb');
const uri = "mongodb://localhost:27017";  // MongoDB connection string

const client = new MongoClient(uri, { useNewUrlParser: true, useUnifiedTopology: true });

async function run() {
    try {
        await client.connect();
        console.log("Connected to MongoDB");
    } catch (err) {
        console.error(err);
    } finally {
        await client.close();
    }
}
run().catch(console.dir);

5. Performing CRUD Operations

Create Operation: Insert a document into a collection.

async function createDocument(db) {
    const collection = db.collection('documents');
    const result = await collection.insertOne({ name: "Alice", age: 28 });
    console.log(`New document id: ${result.insertedId}`);
}

Read Operation: Retrieve documents from a collection.

async function readDocuments(db) {
    const collection = db.collection('documents');
    const documents = await collection.find({}).toArray();
    console.log(documents);
}

Update Operation: Modify documents in a collection.

async function updateDocument(db) {
    const collection = db.collection('documents');
    const result = await collection.updateOne({ name: "Alice" }, { $set: { age: 29 } });
    console.log(`Modified ${result.modifiedCount} document(s)`);
}

Delete Operation: Remove documents from a collection.

async function deleteDocument(db) {
    const collection = db.collection('documents');
    const result = await collection.deleteOne({ name: "Alice" });
    console.log(`Deleted ${result.deletedCount} document(s)`);
}

6. Running the Node.js Application

Execute your application by running:

node app.js

Ensure MongoDB is running locally or adjust the URI to connect to a remote MongoDB server.
