How To Install Node.js on AlmaLinux 9

In this guide, we want to teach you How To Install Node.js on AlmaLinux 9.

Node.js is an open-source, cross-platform runtime environment for developing server-side and networking applications. Node.js applications are written in JavaScript and can be run within the Node.js runtime on OS X, Microsoft Windows, and Linux.

Also, it provides a rich library of various JavaScript modules which simplifies the development of web applications using Node.js to a great extent.

Following are the areas where Node.js is proving itself as a perfect technology partner.

• I/O bound Applications
• Data Streaming Applications
• Data Intensive Real-time Applications (DIRT)
• JSON APIs based Applications
• Single Page Applications

Steps To Install Node.js on AlmaLinux 9

To complete this guide, you must log in to your server as a non-root user with sudo privileges. To do this, you can follow our guide the Initial Server Setup with AlmaLinux 9.

Installing Node.js and NPM LTS on AlmaLinux 9

First, you need to update your local package index with the following command:

sudo dnf update -y

To install the latest release of Node.js, you need to add the Node.js LTS repository on your server.

To do this, you can run the command below:

curl -fsSL https://rpm.nodesource.com/setup_lts.x | sudo bash -

Then, use the command below to install Node.js on AlmaLinux 9:

sudo dnf install nodejs -y

Verify your installation by checking its version:

node --version

Output
v16.17.1

Also, check the NPM version:

npm --version

Output
8.15.0

That’s it, you are done.

Following are some of the important features that make Node.js the first choice of software architects.

• Asynchronous and Event Driven − All APIs of the Node.js library are asynchronous, that is, non-blocking. It essentially means a Node.js-based server never waits for an API to return data. The server moves to the next API after calling it and a notification mechanism of Events of Node.js helps the server to get a response from the previous API call.
• Very Fast − Being built on Google Chrome’s V8 JavaScript Engine, the Node.js library is very fast in code execution.
• Single-Threaded but Highly Scalable − Node.js uses a single-threaded model with event looping. The event mechanism helps the server to respond in a non-blocking way and makes the server highly scalable as opposed to traditional servers which create limited threads to handle requests. Node.js uses a single-threaded program and the same program can provide service to a much larger number of requests than traditional servers like Apache HTTP Server.
• No Buffering − Node.js applications never buffer any data. These applications simply output the data in chunks.
• License − Node.js is released under the MIT license.

Conclusion

At this point, you have learned to Install Node.js LTS on AlmaLinux 9.

Hope you enjoy it.
