Install Nodejs

Posted on  by admin

The first step in using Node.js is the installation of the Node.js libraries on the client system.

How to Install Node.js on Windows

Below are the steps to download and install Node.js in Windows:. Go to the site https://nodejs.org/en/download/ and download the necessary binary files.

How to Install NPM on Windows 10/8/7

In our example, we are going to Download Node.js on Windows with the 32-bit setup files. Step 2) Run the installation. Double click on the downloaded .msi file to start the installation.

Click the Run button on the first screen to begin the installation. Step 3) Continue with the installation steps. In the next screen, click the “Next” button to continue with the installation. In the next screen, Accept the license agreement and click on the Next button.

Step 5) Set up the path. In the next screen, choose the location where Node.js needs to be installed and then click on the Next button.

First, enter the file location for the installation of Node.js. This is where the files for Node.js will be stored after the installation. Click on the Next button to proceed ahead with the installation. Step 6) Select the default components to be installed. Accept the default components and click on the Next button.

Step 7) Start the installation.

On Windows, the NPM (Node Package Manager) download is known as Chocolatey.

  • It was designed to be a decentralized framework for quickly installing applications and tools that you 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.

Sample application

The first step is to run the below 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 below 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 wet.webclient).DownloadString(‘https://chocolatey.org/install.ps1’))” && SET PATH=%PATH%;%ALLUSERSPROFILE%\chocolatey\bin. Step 2) The next step is to install Node.js to your local machine using the Chocolatey, package manager.

Test the application

This can be done by running the below command in the command prompt. cinst nodejs install. If the installation is successful, you will get the message of the successful installation of Node.js.

Note: If you get an error like “C:\ProgramData\chocolatey\lib\libreoffice\tools\chocolateyInstall.ps1” Then manually create the folder in the path. The basic functionality of the “require” function is that it reads a JavaScript file, executes the file, and then proceeds to return an object.

Using this object, one can then use the various functionalities available in the module called by the require function.

So in our case, since we want to use the functionality of HTTP and we are using the require(http) command.

In this 2nd line of code, we are creating a server application which is based on a simple function.

This function is called, whenever a request is made to our server application.

Create a Dockerfile for Node.js

When a request is received, we are asking our function to return a “Hello World” response to the client. The writeHead function is used to send header data to the client, and while the end function will close the connection to the client.

We are then using the server.listen function to make our server application listen to client requests on port no 8080. You can specify any available port over here.

Save the file on your computer: C:\Users\Your Name\ firstprogram.js.

In the command prompt, navigate to the folder where the file is stored. Enter the command Node firstprogram.js. Now, your computer works as a server! If anyone tries to access your computer on port 8080, they will get a “Hello World!” message in return!

Start your internet browser, and type in the address: http://localhost:8080. We have seen the installation of Node.js via the MSI installation module, which is available on the Node.js website. This installation installs the necessary modules which are required to run a Node.js application on the client. Node.js can also be installed via a package manager. The package manager for windows is known as Chocolatey. By running some simple commands in the command prompt, the Chocolatey package manager automatically downloads the necessary files and then installs them on the client machine.

A simple Node.js application consists of creating a server which listens on a particular port. When a request comes to the server, the server automatically sends a ‘Hello World’ response to the client.

This recommendation also applies if you plan to use a Windows Server production environment. It is always recommended to remove any existing installations of Node.js or npm from your operating system before installing a version manager as the different types of installation can lead to strange and confusing conflicts.

For example, the version of Node that can be installed with Ubuntu's apt-get command is currently outdated. For help with removing previous installations, see How to remove nodejs from ubuntu.). Open your Ubuntu command line (or distribution of your choice). Install cURL (a tool used for downloading content from the internet in the command-line) with: sudo apt-get install curl.

Install nvm, with: curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash. As of January 25, 2022, NVM v0.39.1 is the most recent version available. You can check the GitHub project page for the latest release of NVM, and adjust the above command to include the newest version.Installing the newer version of NVM using cURL will replace the older one, leaving the version of Node you've used NVM to install intact.

For example: curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash.

To verify installation, enter: command -v nvm ..this should return 'nvm', if you receive 'command not found' or no response at all, close your current terminal, reopen it, and try again.

Learn more in the nvm github repo. List which versions of Node are currently installed (should be none at this point): nvm ls.

Install both the current and stable LTS versions of Node.js. In a later step, you'll learn how to switch between active versions of Node.js with an nvm command.

Install the current stable LTS release of Node.js (recommended for production applications): nvm install --lts. Install the current release of Node.js (for testing latest Node.js features and improvements, but more likely to have issues): nvm install node.

List what versions of Node are installed: nvm ls ..now you should see the two versions that you just installed listed. Verify that Node.js is installed and the currently default version with: node --version.

Then verify that you have npm as well, with: npm --version (You can also use which node or which npm to see the path used for the default versions).

To change the version of Node.js you would like to use for a project, create a new project directory mkdir NodeTest, and enter the directory cd NodeTest, then enter nvm use node to switch to the Current version, or nvm use --lts to switch to the LTS version.

You can also use the specific number for any additional versions you've installed, like nvm use v8.2.1.

(To list all of the versions of Node.js available, use the command: nvm ls-remote). n is a long-standing nvm alternative that accomplishes the same thing with slightly different commands and is installed via npm rather than a bash script.

fnm is a newer version manager, claiming to be much faster than nvm. (It also uses Azure Pipelines.).

Volta is a new version manager from the LinkedIn team that claims improved speed and cross-platform support. asdf-vm is a single CLI for multiple languages, like ike gvm, nvm, rbenv & pyenv (and more) all in one.

nvs (Node Version Switcher) is a cross-platform nvm alternative with the ability to integrate with VS Code. This “remote” scenario is a bit different than you may be accustomed to.

Next steps

WSL supports an actual Linux distribution where your project code is running, separately from your Windows operating system, but still on your local machine. The Remote-WSL extension connects with your Linux subsystem as if it were a remote server, though it’s not running in the cloud… it’s still running on your local machine in the WSL environment that you enabled to run alongside Windows.

Feedback

Linux-based Intellisense and linting is supported. Your project will automatically build in Linux. You can use all your extensions running on Linux (ES Lint, NPM Intellisense, ES6 snippets, etc.).
