How to Install NPM on Windows 10/8/vii

The other fashion to install Node.js on whatever client machine is to use a "package director."

On Windows, the NPM (Node Package Manager) download is known as Chocolatey. It was designed to be a decentralized framework for rapidly installing applications and tools that you need.

Step 1) Installing Chocolatey – The Chocolatey website (https://chocolatey.org/) has very clear instructions on how this framework needs to be installed.

• The first footstep is to run the below control in the command prompt windows. This control is taken from the Chocolatey spider web site and is the standard control for installing Node.js via Chocolatey.
• The below command is a PowerShell control which calls the remote PowerShell script on the Chocolatey website. This control needs to be run in a PowerShell control window.
• This PowerShell script does all the necessary work of downloading the required components and installing them accordingly.

@powershell -NoProfile -ExecutionPolicy Bypass -Command "iex ((new-object moisture.webclient).DownloadString('https://chocolatey.org/install.ps1'))" && Prepare PATH=%PATH%;%ALLUSERSPROFILE%\chocolatey\bin

Step 2) The side by side step is to install Node.js to your local car using the Chocolatey, package manager. This can be done past running the beneath command in the command prompt.

cinst nodejs install

Running your beginning How-do-you-do World application in Node.js

Once yous have Node.js download and installed on your computer, let'south try to brandish "Hello World" in a web browser.

var http = require('http');  http.createServer(part (req, res) {     res.writeHead(200, {'Content-Type': 'text/html'});     res.stop('Hello Globe!'); }).heed(8080);          

Code Explanation:

1. The basic functionality of the "require" part is that it reads a JavaScript file, executes the file, so proceeds to return an object. Using this object, ane tin and then use the various functionalities available in the module chosen by the require function. And so in our case, since we want to use the functionality of HTTP and nosotros are using the crave(http) command.
2. In this 2^nd line of code, nosotros are creating a server application which is based on a simple function. This function is chosen, whenever a request is made to our server awarding.
3. When a asking is received, we are request our role to render a "Hello World" response to the client. The writeHead part is used to send header data to the client, and while the terminate function volition shut the connection to the customer.
4. Nosotros are then using the server.mind function to make our server application listen to client requests on port no 8080. You can specify any available port over hither.

Executing the code

1. Save the file on your estimator: C:\Users\Your Name\ firstprogram.js
2. In the control prompt, navigate to the folder where the file is stored. Enter the command Node firstprogram.js

1. Now, your computer works every bit a server! If anyone tries to access your figurer on port 8080, they will go a "Hello World!" message in return!
2. Start your internet browser, and type in the accost: http://localhost:8080
