How to Install Node.js on Ubuntu Server 12.04
Step 1: Update and Upgrade
Before installing Node.js, it is essential to update and upgrade Ubuntu Server to ensure that we have the latest packages and dependencies.
To update and upgrade, open the terminal and type the following commands:
sudo apt-get update
sudo apt-get upgrade
Step 2: Install Node.js
There are different ways to install Node.js on Ubuntu Server. In this article, we will be using the following commands:
sudo apt-get install -y nodejs
sudo apt-get install -y npm
After running the commands, you can verify if Node.js and npm are installed properly by typing the following commands:
node -v
npm -v
Step 3: Verify Installation
To check if Node.js and npm are installed correctly, create a test file by typing the following command:
nano test.js
Then, copy and paste the following code:
console.log("Hello, World!");
Save the file by pressing CTRL+X and then Y and Enter.
Finally, run the file by typing the following command:
node test.js
If the result is “Hello, World!”, then Node.js is installed correctly!
Step 4: Install Node Version Manager (Optional)
If you need to install different versions of Node.js or switch between them, it is recommended to install Node Version Manager (NVM). To install NVM, type the following commands:
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash
source ~/.bashrc
To check if NVM is installed correctly, type the following command:
nvm --version
Step 5: Install Global Packages (Optional)
You can install global packages using npm. To install a global package, type the following command:
sudo npm install -g [package-name]
For example, to install the express package, type:
sudo npm install -g express
Advantages and Disadvantages of Using Node.js on Ubuntu Server 12.04
Advantages
Easy to Learn and Use
Node.js uses JavaScript, a language that most developers are already familiar with. It eliminates the need to learn a new language or framework. Additionally, it has a simplified syntax that makes it easy to read and write code.
Fast and Scalable
Node.js uses an event-driven, non-blocking I/O model that makes it fast and efficient. It also has a single-threaded event loop that allows it to handle multiple connections simultaneously. This allows Node.js to handle a large number of requests and scale easily.
Large Community and Ecosystem
Node.js has a large and active community that provides support, feedback, and updates. It also has a wide range of open-source modules and packages that can be easily installed using npm.
Disadvantages
Not Suitable for CPU-Intensive Tasks
Node.js is not suitable for CPU-intensive tasks and performs poorly compared to other languages that are designed for such tasks. It is primarily designed for I/O bound applications.
Callback Hell
Node.js heavily relies on callbacks, which can lead to callback hell, a situation where the code becomes nested and difficult to read and maintain.
Immature Tools and Frameworks
Node.js is relatively new compared to other languages, which means that the tools and frameworks are still immature and may lack some features.
