Using Node.js with MongoDB

Introduction to MongoDB

MongoDB is a popular NoSQL database that allows you to store data in a flexible and scalable way.

Step 1: Install MongoDB

Install MongoDB on your computer and start the MongoDB server.

brew install mongodb
mongod

Step 2: Install the MongoDB Driver

Install the MongoDB driver for Node.js.

npm install mongodb

Step 3: Connect to MongoDB

Connect to the MongoDB server using the mongodb package.

const MongoClient = require('mongodb').MongoClient;
const url = 'mongodb://localhost:27017';
MongoClient.connect(url, (err, client) => {
  if (err) {
    console.log(err);
  } else {
    console.log('Connected to MongoDB');
  }
});

Step 4: Create a Collection

Create a new collection in the MongoDB database.

const db = client.db();
const collection = db.collection('users');

Step 5: Perform CRUD Operations

Perform CRUD operations on the collection.

// Create a new document
const user = { name: 'John Doe', age: 30 };
collection.insertOne(user, (err, result) => {
  if (err) {
    console.log(err);
  } else {
    console.log('Document inserted');
  }
});
