Introduction<\/h2>\n\n\n\n

Node.js is essentially code executed on our servers to host, create and control web applications using this type of language.<\/p>\n\n\n\n

In the following, we will focus on information for beginners. We will start by explaining how to access Node.js in N0C and we will provide a detailed example of launching and modifying an application using this interface.<\/p>\n\n\n\n

Then, for more advanced users, we will explain how to do these same operations in command line.<\/p>\n\n\n\n

Note :<\/strong> The Glossary of N0C<\/a> contains explanations on multiple topics and can be consulted to clarify certain terms.<\/p>\n\n\n\n

Documentation<\/h2>\n\n\n\n

Documentation on Node.js can be found on the Web, in particular under: https:\/\/nodejs.org\/en\/docs\/guides\/<\/a>.<\/p>\n\n\n\n

You can also refer to this site for more information: https:\/\/docs.cloudlinux.com\/command-line_tools\/#node-js-selector<\/a>.<\/p>\n\n\n\n

Debugging Applications<\/h3>\n\n\n\n

When an error occurs, a page like the one below is displayed:<\/p>\n\n\n

This page is not very explanatory. Activating the development mode allows you to investigate (please refer to the article How to Debug a Node.js, Ruby or Python Application<\/a>).<\/p>\n\n\n\n

Prerequisite<\/h2>\n\n\n\n

    Implementation of a New Node.js Application with N0C<\/h2>\n\n\n\n

    Should you decide to deploy effortlessly a Nuxt.js application on N0C hosting, please refer to this guide<\/a>. The manual approach is explained in this video<\/a>.<\/p>\n\n\n\n

    To explain the approach more easily, we will proceed with an example. <\/p>\n\n\n\n

    Let’s say you want to create the app2.js<\/strong> application that displays the words “Hello World! NodeJS”. Three steps are necessary:<\/p>\n\n\n\n

      \n
    1. First of all, you have to create an application<\/strong> in the directory intended to contain it (we will call this directory “app2<\/strong>” as an example, but the user can give it the name they desire). When it is executed, the application displays the words “It works!”.<\/li>\n\n\n\n
    2. Then you have to program<\/strong> it appropriately (in our example, so that it displays “Hello World! NodeJS”) and create a “package.json<\/strong>” file. <\/li>\n\n\n\n
    3. Finally, you have to invoke<\/strong> the application environment.<\/li>\n<\/ol>\n\n\n\n

      Step #1 \u2013 Creation of an Application with Nodejs<\/h3>\n\n\n\n

      Make sure the app2<\/strong> directory is created (please refer to the article How to Use the File Manager<\/a>).<\/p>\n\n\n\n

        \n
      1. Click on the Create <\/strong>button:<\/li>\n<\/ol>\n\n\n
