Linux is a very popular operating system, especially on the server side. Node.js is a runtime environment that allows JavaScript code to run on the server side. In this article, we will discuss how to install the v8 version of Node.js on a Linux system.
- Update system packages
Before installing Node.js, we need to ensure that our system has been updated to the latest version. The following commands can be used to update the package list and package library:
sudo apt-get update sudo apt-get upgrade
- Add Node.js official source
First we need to add the official source of Node.js to our In the system:
curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -
- Install Node.js
After adding the source, execute the following command to install Node.js:
sudo apt-get install -y nodejs
- Verification Installation
After completing the installation, we can use the following command to verify that we successfully installed Node.js:
node -v
If the installation was successful, we should see our Node .js version number.
- Install NPM
NPM is the package manager for Node.js. If we want to install various Node.js packages, we need to install NPM. NPM can be installed using the following command:
sudo apt-get install npm
- Verify NPM installation
After the installation is complete, we should verify whether we have successfully installed NPM using the following command:
npm -v
This should output the npm version number we installed.
- Configuring NPM
We can use the following command to configure NPM to change its default location to where we want it:
npm config set prefix ~/npm
- Verify configuration changes
After completing the changes, we can use the following command to verify that we successfully changed the default location of NPM:
npm config get prefix
- Install global packages
Now, we have successfully installed Node.js and NPM and can install the global packages we need. For example, if you want to install gulp:
npm install -g gulp
- Verify global package installation
After the installation is complete, we can use the following command to verify whether we successfully installed the global package:
gulp -v
This should output the version number of gulp we installed.
Summary
In this article, we discussed how to install the v8 version of Node.js on a Linux system. First, we updated the system packages and then added the official source of Node.js. We then installed Node.js and NPM and configured the default location of NPM. Finally, we installed the global packages and verified their installation.

Using indexes as keys is acceptable in React, but only if the order of list items is unchanged and not dynamically added or deleted; otherwise, a stable and unique identifier should be used as the keys. 1) It is OK to use index as key in a static list (download menu option). 2) If list items can be reordered, added or deleted, using indexes will lead to state loss and unexpected behavior. 3) Always use the unique ID of the data or the generated identifier (such as UUID) as the key to ensure that React correctly updates the DOM and maintains component status.

The article discusses HTML5 audio formats and cross-browser compatibility. It covers MP3, WAV, OGG, AAC, and WebM, and suggests using multiple sources and fallbacks for broader accessibility.

SVG and Canvas are HTML5 elements for web graphics. SVG, being vector-based, excels in scalability and interactivity, while Canvas, pixel-based, is better for performance-intensive applications like games.

HTML5 enables drag and drop with specific events and attributes, allowing customization but facing browser compatibility issues on older versions and mobile devices.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
