Node.js

Node.js is a JavaScript runtime environment that allows JavaScript code to run outside the browser — in the backend. It is used to build server-side applications, APIs, and real-time applications such as chats or live dashboards. With its asynchronous, event-driven architecture, Node.js can handle many processes simultaneously, making it ideal for scalable web applications. It is also a great choice for developing tools and automation scripts. Thanks to its integrated package manager npm, the platform is highly versatile.

Activate Node.js

You can activate Node.js from Webhosting L in konsoleH. Log in, select a domain, and click on "Services; Node.js configuration" on the left. Then you can activate Node.js on the right with the red button.

Please note: All other web applications (such as PHP or HTML applications) will be deactivated when Node.js is activated!

Node.js configuration

In konsoleH, you can configure the following and save your changes:

• Script path: Path to your script, relative to the working directory
• Working directory: Path, relative to the home directory, where your Node.js script lies
• Log file: Here you can specify a path to a log file relative to the home directory
• Memory limit: Specify a memory limit
• Version: Select the Node.js version
• Arguments: Add your own arguments
• Environment variables: Add your own environment variables from your script

Examples

     res.end('Hello World');
