Node.js Os Module Tutorial 🎯

Welcome to our comprehensive guide on the Os Module in Node.js! In this lesson, we'll explore the Os Module, a built-in Node.js module that allows you to interact with the underlying operating system. Let's dive in!

Introduction 📝

The Os Module is a powerful tool that helps you read and manipulate system files, directories, and even the current working directory. It's essential for creating robust, cross-platform Node.js applications.

Getting Started 💡

To use the Os Module, simply require it in your JavaScript file:

javascript

const os = require('os');

Basic Usage 📝

Let's start with some basic examples:

Current Working Directory 💡

To get the current working directory, use the os.workingDir() function:

javascript

console.log(os.workingDir());

Operating System Type 💡

To determine the operating system type, use the os.type() function:

javascript

console.log(os.type());

Advanced Examples 🎯

Now that we've covered the basics, let's dive into some more advanced examples.

Reading File 💡

You can read files using the fs module, which is a child module of the Os Module. Here's an example of reading a file:

javascript

const fs = require('fs');

fs.readFile('example.txt', 'utf8', (err, data) => {
  if (err) throw err;
  console.log(data);
});

Creating Directory 💡

To create a directory, use the fs.mkdir() function:

javascript

fs.mkdir('new_directory', (err) => {
  if (err) throw err;
  console.log('Directory created');
});

Os Module Types 📝

The Os Module provides several useful objects:

os (Global Object): Main object with various properties and methods.
os.cpu(): Object containing CPU-related information.
os.network(): Object containing network-related information.
os.platform(): String representing the operating system platform.
os.uptime(): Time in seconds since the operating system was last booted.
