Node.js installation and version management in Node.js - Mini Project: Build & Apply

Node.js Installation and Version Management

📖 Scenario: You want to set up Node.js on your computer so you can run JavaScript programs outside the browser. You also want to manage different versions of Node.js easily, like switching between versions for different projects.

🎯 Goal: Learn how to install Node.js and use a version manager to switch between Node.js versions smoothly.

📋 What You'll Learn

Create a variable called nodeVersion with the exact string value "18.16.0" representing the Node.js version to install.

Create a variable called nvmInstallCommand with the exact string value "nvm install 18.16.0" to install Node.js version 18.16.0 using NVM.

Create a variable called nvmUseCommand with the exact string value "nvm use 18.16.0" to switch to Node.js version 18.16.0.

Create a variable called checkVersionCommand with the exact string value "node -v" to check the current Node.js version.

💡 Why This Matters

🌍 Real World

Developers often need to install and switch between different Node.js versions to match project requirements or test compatibility.

💼 Career

Knowing how to manage Node.js versions is essential for backend developers, DevOps engineers, and anyone working with JavaScript outside the browser.

1

Set the Node.js version to install

Create a variable called nodeVersion and set it to the string "18.16.0" which is the Node.js version you want to install.

Node.js

// Your code here

Use const to create a variable and assign the version string exactly.

2

Create the NVM install command

Create a variable called nvmInstallCommand and set it to the string "nvm install 18.16.0" to install Node.js version 18.16.0 using NVM.

Node.js

const nodeVersion = "18.16.0";
// Your code here

Need a hint?

Use the exact string including nvm install and the version number.

3

Create the NVM use command

Create a variable called nvmUseCommand and set it to the string "nvm use 18.16.0" to switch to Node.js version 18.16.0.

Node.js

const nodeVersion = "18.16.0";
const nvmInstallCommand = "nvm install 18.16.0";
// Your code here

Need a hint?

Use the exact string including nvm use and the version number.

4

Create the command to check Node.js version

Create a variable called checkVersionCommand and set it to the string "node -v" which is the command to check the current Node.js version.

Node.js

const nodeVersion = "18.16.0";
const nvmInstallCommand = "nvm install 18.16.0";
const nvmUseCommand = "nvm use 18.16.0";
// Your code here

Need a hint?

Use the exact string node -v to check the Node.js version.
