What is Node.js? Instructions on how to install Node.js on cPanel

Currently, it is easy to see that Node.js is being used by quite a lot of people. This is because Node.js can support users in running on multiple platforms and multiple devices. In this article, Vcloudia will share with readers in more detail about the concept of what Node.js is, along with how to install Node.js on cPanel.

What is Node.js?

Node.js is a software system designed for writing internet applications for high scalability, particularly Web servers. The program is written in the JavaScript language, utilizing event-driven and asynchronous input/output techniques to optimize costs while still enhancing scalability. Node.js includes Google's V8 JavaScript engine, libUV, and several other libraries.

In particular, when understanding clearly what Node.js is, users will see it is different from most Javascript programs. Node.js will not run on a browser, but it will run on a Server. Node.js uses many technical specifications of CommonJS and provides a REPL environment for users to conduct interactive testing.

Characteristics of Node.js

Below are four main characteristics of Node.js:

1. Asynchronous

When learning about what Node.js is, users will see that all of Node.js's APIs are asynchronous, meaning it will primarily rely on the Node.js Server foundation and then wait for the Server to return data. The server moving to the subsequent APIs after a call, along with Node.js's event notification mechanism, also helps the server get a response from previous API calls (Realtime).

2. Speed

Node.js is built on the V8 Javascript Engine platform, so program execution speed is very fast. And this is something that quite a lot of users are interested in when learning about what Node.js is.

Node.js uses a single-threaded program, and similar programs can provide services for a significantly larger number of requests compared to traditional server requirements like Apache HTTP Server. When you understand what Node.js is, you will find this truly amazing.

3. No buffering

Node.js does not buffer any data, and these applications primarily output data.

4. Licensed

Node.js is licensed under the MIT License. If you did not learn about what Node.js is, you probably wouldn't notice this.

Instructions on how to install Node.js on CPanel

- Step 1: To install Node.js, users need to access cPanel, and in the “Software” section, users click on “Setup Node.js App”.

Starting the process of installing Node.js on cPanel

- Step 2: Next, users continue to select “Create Application”.

- Step 3: At this time, a new interface page will appear; the user's task is to fill in all the information completely and accurately, then select “Create”.

+ Node.js version: Users should select the latest versions. This is what many users choose once they clearly understand what Node.js is.

+ Application module: Depending on usage needs, users can select “Development” or “Production”.

+ Application root: Users need to enter the path to the folder containing the application's code, calculated from the root directory when accessing the hosting.

+ Application URL: Users select the domain name to be used to run the Node.js application. Note that this domain name must point to the hosting's IP, then continue to enter the path to the directory containing the code

+ Application startup file: Enter the path to the file that will be used to run the script.

- Step 4: After clicking “Create”, the creation process will begin, and then the system will notify the user that the Node.js application has been successfully created.

Conclusion

In reality, clearly understanding and grasping the concept of what Node.js is, along with how to install Node.js on cPanel, is not too difficult. Using Node.js will bring quite a few notable advantages for users. Hopefully, this article by us will bring readers a lot of useful information and knowledge.
