How to Install NPM on Windows 10/8/7

The other mode to install Node.js on any client machine is to use a "package managing director."

On Windows, the NPM (Node Parcel Manager) download is known as Chocolatey. It was designed to be a decentralized framework for quickly installing applications and tools that y'all need.

For installing NPM on Windows via Chocolatey, the following steps need to be performed.

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

• The first pace is to run the beneath command in the command prompt windows. This command is taken from the Chocolatey web site and is the standard command for installing Node.js via Chocolatey.
• The beneath command is a PowerShell command which calls the remote PowerShell script on the Chocolatey website. This command needs to be run in a PowerShell command 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

Pace 2) The next stride is to install Node.js to your local car using the Chocolatey, package director. This tin can be done past running the below control in the command prompt.

cinst nodejs install

Code Explanation:

1. The bones functionality of the "crave" function is that it reads a JavaScript file, executes the file, and then gain to return an object. Using this object, one can then use the diverse functionalities available in the module called by the crave function. So in our case, since we want to utilize the functionality of HTTP and we are using the require(http) command.
2. In this 2^nd line of code, we are creating a server application which is based on a simple function. This part is called, whenever a request is fabricated to our server application.
3. When a request is received, we are asking our function to return a "Hello Globe" response to the client. The writeHead function is used to transport header data to the client, and while the end function will shut the connection to the client.
4. Nosotros are and so using the server.listen function to make our server application listen to client requests on port no 8080. You can specify whatever available port over here.

Executing the lawmaking
