3. Configure the Server: After installation, open the Couchbase Web Console by navigating to http://localhost:8091. Create an administrator account and set up the default bucket or create a new one.

1. Install Node.js: Download the latest version of Node.js from the official Node.js website. Install it using the provided installer for your platform.
2. Verify Installation: Open a terminal and run node -v to check the installed version. This ensures Node.js is installed correctly.
3. Install Couchbase SDK: In your project directory, run npm install couchbase to add the Couchbase Node.js SDK. This package allows our application to interact with Couchbase Server.
4. Create and Test a Project: Initialize a new Node.js project using npm init -y. Create a JavaScript file, typically app.js, and write a simple script to connect to Couchbase Server using the SDK. This verifies that both Node.js and Couchbase SDK are set up properly.

const couchbase = require('couchbase');
const cluster = new couchbase.Cluster('couchbase://localhost', {
username: 'Administrator',
password: 'password'
});
const bucket = cluster.bucket('default');
const collection = bucket.defaultCollection();

console.log('Connection successful');

By following these steps, our development environment for Couchbase and Node.js is ready. This setup ensures we can now build and manage high-performance, scalable applications leveraging real-time data processing capabilities.
