This guide gives a fast and simple stroll through for introducing Node.js and NPM on two Windows and Mac. From downloading the right rendition to confirming the establishment, we cover every one of the essential moves toward preparing your set up and to begin creating.
Here is our detailed guide on introducing Node.js and NPM on Windows and Mac! Node.js has turned into a foundation in current web improvement, offering a productive and versatile method for making network applications. Close by it, Node Package Manager (NPM) fills in as the help for overseeing bundles in Node.js. Whether you’re a fledgling venturing into the universe of improvement or an accomplished proficient hoping to find a way to improve your abilities, this guide will walk you through the establishment cycle in a clear, bit-by-bit way.
What is NPM
NPM is utilized to oversee project conditions by introducing, refreshing, and dealing with the numerous libraries and bundles that an undertaking might require. Little utilities to frameworks are examples of these packages.
Each bundle incorporates a form number and a rundown of conditions, guaranteeing that ventures have all that they need to flawlessly execute. Moreover, NPM provides an enormous assortment of open-source packages, making it a significant asset for developers wishing to utilize existing arrangements or offer their work to others.
This capacity further develops improvement processes as well as empowers a worldwide developer community of sharing and cooperation.
Components of NPM
Command Line Interface (CLI): NPM gives an order line interface that developers use to collaborate with the package registry, oversee project conditions, and run scripts. This CLI instrument is fundamental for introducing, refreshing, and overseeing packages within a project, and it offers different orders to smooth out these processes.
Package.json File: The package.json file is a key component in any Node.js project using NPM.It contains metadata about the task, like name, adaptation, and conditions. This document is utilized to give data to NPM that permits it to distinguish the undertaking as well as handle the venture’s conditions.
Its non-blocking, occasion-driven architecture is considered magnificent execution, making it ideal for creating versatile network applications, for example, web servers, chat apps, and real-time communication apps.
To begin with Node.js and NPM, you’ll require a couple of fundamental components:
Operating System Compatibility: Node.js and NPM are cross-stage and might be introduced on Windows, macOS, and Linux. For the best similarity and security, ensure your working framework is state-of-the-art.
Node.js Installation: In light of the fact that NPM is incorporated with Node.js, you should initially introduce Node.js. It is accessible for download from the Node.js site. Select the right adaptation for your situation; for the most part, the LTS (long-term maintenance) variant is liked for its unwavering quality and broadened support.
Skills in Command Line Interface (CLI): Node.js and NPM frequently cooperated with utilizing an order line interface. Fundamental CLI capacities are required, for example, directories and running commands.
Internet access is required to download Node.js and NPM packages, as well as to access online resources, documentation, and communities.
Understanding of Version Control (Optional but Recommended): Comprehension of a rendition control framework, for example, Git can be helpful, particularly while dealing with bigger tasks or helping out others.
How to Install Node.js and NPM on Windows and Mac?
Installing Node.js and NPM on both Windows and Mac is a straightforward process. Here’s a step-by-step guide for both operating systems:
Run the Installer:
Run the Installer:
Using Homebrew (Alternative Method):
First, install Homebrew by opening the Terminal and running:
Then, install Node.js with:
By following these steps, you will have successfully installed Node.js and NPM on your Windows or Mac computer, setting you up for developing applications with Node.js.
How to Install Node Using “Homebrew”?
Install Node.js and NPM:
Installing Node.js and NPM on your Mac is very easy using Homebrew. Homebrew simplifies the process by managing the download, unpacking, and installation of Node and NPM for you.
First, open your Terminal and run the following command:
brew install node
This command will download and install the necessary files for Node.js and NPM. Wait for the process to complete.
Step 2: Verify Node.js and NPM Installation
After installing Node.js and NPM, it’s important to verify that the installation was successful. This process is similar to verifying the installation on a Windows system.
In your Terminal, run the following commands:
For Node.js, type and run:
This command displays the installed version of Node.js.
For NPM, type and run:
This command displays the installed version of NPM.
Homebrew also helps in keeping Node.js and NPM up to date. Ensure that you have the latest version of Node package available in Homebrew.
If you need to update Homebrew itself, run the following command:
To upgrade to the latest version of Node.js and NPM, execute
brew upgrade node
This command updates Node.js and NPM to their latest available versions.
By following these steps, you will have successfully installed and verified Node.js and NPM on your Mac using Homebrew, with the added advantage of easy updates in the future.
This format provides a clear and concise guide for Mac users to install and verify Node.js and NPM using Homebrew, along with instructions for keeping their installations up to date.
How to Install Node Using NVM – Node Version Manager?
Installing Node.js using NVM (Node Version Manager) is a great choice, especially if you need to manage multiple versions of Node.js. NVM allows you to install and switch between different Node versions with ease. Here’s how to do it:
For Linux and macOS:
Open your terminal.
To install NVM, run the following curl or wget command:
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash
wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash
The script clones the NVM repository to ~/.nvm and adds the source line to your profile (~/.bash_profile, ~/.zshrc, ~/.profile, or ~/.bashrc).
To activate NVM, either close and reopen your terminal or run the following command:source ~/.bashrc
Alternatively, for zsh users: source ~/.zshrc.
Check if NVM Was Installed Successfully:
Run nvm –version to check if NVM was installed successfully.
Now, you can install Node.js. To install the latest version, run:
nvm install node
To install a specific version, use:
nvm install 14.17.3
(Replace 14.17.3 with your desired version.)
Switch Between Node Versions:
You can switch between installed versions using:
nvm use 14.17.3
Set a default Node version with:
nvm alias default 14.17.3
Check the Node version using node -v.
Check the NPM version using npm -v.
NVM for Windows is a separate project from NVM. To install:
Download NVM for Windows:
Run the Installer:
Install and Use Node:
Key Pointers to Consider:
Installing Node.js with NPM on Windows and Mac is a simple operation that unlocks a world of possibilities in modern web development. Whether you’re a seasoned developer or just getting started, the procedures detailed in this tutorial give a clear route to efficiently setting up your work environment.
