Greetings, dear readers! If you’re reading this article, it’s because you’re probably interested in learning how to install nodejs on your Ubuntu server. Nodejs is a popular open-source runtime environment that allows you to run Javascript on the server-side. Whether you’re a developer, a system administrator, or just a curious person, this article will guide you through the entire installation process.
Why Install Nodejs on Ubuntu Server?
Before we dive into the installation process, let’s understand why you might want to install nodejs on your Ubuntu server in the first place. Here are some of the top advantages:
1. Better Performance
Nodejs is built on top of Google’s V8 engine, which means it’s incredibly fast and efficient. This makes it an ideal choice for building real-time, data-intensive applications that require low-latency and high-throughput.
2. Cross-Platform Compatibility
Nodejs is a cross-platform runtime environment, which means that you can write your code once and run it on any operating system, including Windows, macOS, and Linux.
3. Large Community and Ecosystem
Nodejs has a large and active community of developers, which means that you’ll never be short on resources, tutorials, or support. Additionally, there are thousands of open-source packages and libraries available through the Node Package Manager (npm) that you can use to extend the functionality of your application.
How to Install Nodejs on Ubuntu Server
Now that we’ve covered why you might want to install nodejs, let’s jump into the installation process. Here are the steps you’ll need to follow:
Step 1: Update Your System
Before installing nodejs, it’s important to ensure that your system is up-to-date. You can do this by running the following commands:
“`sudo apt updatesudo apt upgrade“`
Step 2: Install Nodejs
Once your system is up-to-date, you can install nodejs by running the following command:
“`sudo apt install nodejs“`
This command installs the latest version of nodejs that’s available in the Ubuntu repositories. However, it’s worth noting that the version of nodejs that’s available in the Ubuntu repositories may not be the latest version. If you need a specific version of nodejs, you’ll need to use a different installation method.
Step 3: Install NPM
Nodejs comes with a package manager called npm, which you can use to install and manage packages. You can install npm by running the following command:
“`sudo apt install npm“`
Once npm is installed, you can use it to install packages like this:
“`npm install
Step 4: Verify Installation
Once you’ve installed nodejs and npm, you can verify that they’re working correctly by running the following commands:
“`node -vnpm -v“`
These commands should output the versions of nodejs and npm that you’ve installed.
Advantages and Disadvantages of Installing Nodejs on Ubuntu Server
Advantages
1. Fast and Efficient

Additionally, there are thousands of open-source packages and libraries available through the Node Package Manager (npm) that you can use to extend the functionality of your application.
Disadvantages
1. Asynchronous Programming
Nodejs is based on asynchronous programming, which can be difficult to understand for developers who are used to traditional synchronous programming. This can result in code that’s difficult to read and maintain.
2. Single-Threaded
Nodejs is single-threaded, which means that it can only utilize a single core of your CPU. This can limit the performance of your application if you’re running it on a machine with multiple cores.
3. Memory Management
Nodejs uses a garbage collector to manage memory, which can result in performance issues if not used correctly.
