How Do I Access Command-Line Arguments in Node.js?

Accessing Command-Line Arguments in Node.js

In Node.js, command-line arguments can be conveniently obtained via the process.argv array. This array contains all the arguments passed to the program when it was executed.

Standard Method

Node.js provides a built-in mechanism to handle command-line arguments through process.argv:

const args = process.argv.slice(2);

Here, args will contain an array of arguments passed after the Node.js executable and the script file name. For instance, running the program as node server.js folder would result in args containing ["folder"].

Example: Reading a Folder Argument

To access the specified folder argument in your web server, you can do the following:

console.log(Launching server with folder: ${folder});

This will output the specified folder, allowing you to further process it in your server code.
