Node Js can be installed from brew Or we can download and install manually.

2. Installing node manually:
After installing the NodeJs by following either of the above 2 procedures we need to verify whether npm is ready to use.
Now, open another terminal window and type ânpmâ and hit enter.
If you observe â-bash: npm: Command not foundâ, you need to append npm location to the $PATH environment variable. Please execute the below commands in set $PATH for npm.

Your NodeJs is installed and npm is ready to use.
In order to use almost any development tools based in JavaScript, you'll need to know how to use npm and Node.js. Gulp, Grunt, and Webpack are a few examples of popular technologies you may have heard of that require a knowledge of the Node ecosystem.
I find myself writing about this over and over again in the prerequisites of an article I've begun to write. I'd prefer to write one definitive guide to refer to in the future, so here it is.
Prerequisites
Goals
What is Node.js?
JavaScript is a client-side programming language, which means itâs processed in the browser. With the advent of Node.js, JavaScript can also be used as a server-side language.
What is npm?
npm doesn't stand for Node Package Manager*, which means itâs the tool to connect to the repository containing all the Node.js programs, plugins, modules and so on.
*npm actually does not stand for 'Node Package Manager' but essentially that's what it is and does, so most people refer to it that way.
Local vs. GlobalHow To Download Npm On Mac
This is the most confusing concept to understand at first, so it's important to let this settle in. Traditionally, you're used to globally installing any sort of program or software on your computer. If you want Spotify, you'll download Spotify, and then it will be available to you.
With npm, you will have some global installs, but mostly everything will be done on a local project basis, meaning you'll have to install everything you need for each project in its own directory. If you want to have a project running Gulp and Sass, you'll create a directory, with a new npm install.
For future reference, any global installations will have the
-g flag.
Installation on Windows
Installing everything on Windows is a breeze.
Install Node.js and npm
Node.js and npm can be installed from a download link. Go to the Node installation page, and download the Node installer. I have a 64-bit Windows 10 OS, so I chose that one.
Once it's done, you can test to see both node and npm functioning by opening PowerShell (or any shell) and typing
node -v and npm -v , which will check the version number.
Install Node Js On Mac
All set.
Installation on a Mac or Linux
WinRAR 5.91 Arabic 64 bit. In order to install everything on a Mac, we'll be running commands in Terminal.app, and Linux distributions vary.
Install Node.js and npm
Weâre going to use Node Version Manager (nvm) to install Node.js and npm.
Open the
~/.bash_profile file, and make sure source ~/.bashrc is written in there somewhere. Restart the terminal.
Run the install command.
Run the use command.
Now that Node.js and npm are installed, test them by typing
node -v and npm -v .
All set.
Create a Project
At this point, you're set to start setting up Gulp, Webpack, Browserify, or whatever your aim is. We can also create a simple project to test that everything is working properly.
Initialize Project
Navigate to the directory in which you want your project to exist - in my case, sites/node-test.
Now initalize a new project with npm.
The following will pop up in the terminal, and prompt you for a few
First, it will ask for a package name.

Description.
The rest you can just press enter and skip. Now you'll notice we have a package.json file that contains all the information we entered.
A package.json is a file that contains metadata about the project, and handles the dependencies (additional software and modules) of the project.
Now, we're going to install our first dependency - a very important and useful package called left-pad, which will add white space to the left side of a string, adding up to a number.
For example, writing this:
Will output this:
left-pad is a package on npm, which as we stated previously contains the registry for all publicly available packages.
Install dependencies
To install a dependency with npm, we use the command
npm install dependency-name-here . Now, simply running npm install will download the dependency, but it won't save it to the project. Since we've already created our package.json, we'll use the flag --save to install the dependency and add it to package.json.
As long as you ran this command inside the project directory, it will successfully install the dependency by creating a node_modules directory. It will also create a package-lock.json file, which we can ignore. Finally, it updated our package.json file with a new line.
Now the project recognizes the left-pad dependency as existing
You can also run
npm install --save-dev to specify that the dependency will only be used for development (not production) purposes.
Run Node in the terminal
Let's create index.js in the root of our directory. This is everything you should have now:
For future reference, don't bother looking in the node_modules rabbit hole. It will get really overwhelming with bigger projects.
In order to use a dependency, we use
require() and put it in a variable, like so:
This will be the entirety of our index.js file, in which we require left-pad, run a
leftPad() function, and send it to the console.
Since Node.js is not recognized by the browser, we'll be testing this in the console. In your shell, run the
node command followed by the filename in the root of your project.
If everything went well, you should have printed
Hello, World! to the console, with two spaces on the left.
