Steps to Create Application And Installing Module
To create an application using MongoDB:
Step 1: Install MongoDB driver for Node.js
install mongodb
Step 2: Set up your MongoDB connection in your Node.js application.
npm init -y
Step 3: Install the package using the below command
npm install mongodb
The Updated Dependencies in your package.json file is:
After installing the MongoDB driver, your package.json file should include:
"dependencies": {
"mongodb": "^46.6.1
}
Example: Below is an example to show the scaling behaviour in MongoDB.
// server.js
const { MongoClient } = require('mongodb');
// Connection URI
const uri = 'mongodb://localhost:27017';
// Create a new MongoClient
const client = new MongoClient(uri);
async function main() {
try {
// Connect to the MongoDB server
await client.connect();
console.log('Connected to MongoDB');
// Use a specific database
const database = client.db('mydb');
// Use a specific collection
const collection = database.collection('mycollection');
// Insert a document
await collection.insertOne({
name: 'w3wiki'
});
console.log('Document inserted');
// Find documents
const docs = await collection.find().toArray();
console.log('Found documents:', docs);
} catch (error) {
console.error('Error:', error);
} finally {
// Close the connection
await client.close();
console.log('Connection closed');
}
}
main();
Output:
Scaling Behaviour in MongoDB
Horizontal Vs Vertical Scaling in MongoDB
Horizontal and vertical scaling are two common strategies used to handle increasing loads or data volumes in databases like MongoDB. MongoDB is a popular open-source, NoSQL database management system that uses a document-oriented data model. It has multiple features like high performance, flexibility, and scalability. In this article, we will talk about its scalability aspect.
